Building a Used Car Marketplace Like Carvana from Scratch

What is Carvana and Why Is It Successful?

Carvana Overview: Carvana is a leading online used car retailer in the United States that has revolutionized how people buy and sell cars. Founded in 2012 and based in Tempe, Arizona, Carvana operates entirely online with no traditional dealerships (Business Model Analyst). Customers can browse a vast inventory of vehicles on Carvana’s website or app, complete the purchase process digitally, and have the car delivered to their door or pick it up from one of Carvana’s iconic car vending machines. Carvana makes its money by sourcing used cars (from auctions, trade-ins, etc.) and reselling them at a profit, effectively acting as both the buyer and seller in transactions.

Key Features & Innovations: Several features set Carvana apart and have driven its success:

Extensive Online Inventory & 360° Tours: Carvana’s platform lists thousands of cars with high-resolution photos and 360-degree virtual tours of each vehicle’s interior and exterior (Snappr). This immersive browsing experience addresses a major pain point for online car shoppers. As per my research, buyers spend ~96 days researching cars on average, and 59% of that time is online. Carvana capitalized on this by offering detailed imagery and interactive galleries; studies show online car buyers consider vehicle photos 3× more important than detailed descriptions.
No-Haggle Pricing & Transparency: Carvana lists upfront, transparent prices for each car with no haggling (PitchGrade). This “what you see is what you pay” model builds trust, especially since many buyers dread the traditional dealership negotiation process. Every Carvana vehicle is “Carvana Certified” after passing a 150-point inspection and comes with a free Carfax report, clean title guarantee, and no reported accidents.
Convenience and Guarantee: The entire purchase can be done online in minutes, including financing and trade-ins. Cars are delivered to the customer’s home or retrieved from a vending machine, and Carvana offers a 7-day money-back guarantee on purchases.
In-House Financing: Carvana provides financing options directly through its platform.
Unique Marketing & Branding: Carvana’s brand centers on making car buying “fun, fast, fair, and powered by technology.” They’re known for the novelty of car vending machines and a customer-centric image.

Takeaway: Carvana works by marrying e-commerce convenience with automotive retail. It solved common buyer pain points (limited local inventory, high-pressure sales, lack of trust) through technology and customer-first policies. As I found, features like interactive car previews, no-haggle pricing, rigorous inspections, and online checkout have given Carvana a competitive edge in the used car market. These are key lessons for any entrepreneur looking to create a similar used car marketplace from scratch.

Building a Carvana-Style Platform from Scratch

Creating a Carvana-like used car marketplace involves developing a robust web platform (and possibly mobile app) that can handle listings, user accounts, transactions, and more. It requires a combination of front-end development (what users see and interact with), back-end development (server logic, databases, APIs), and scalable server architecture (hosting, cloud services, security). Below is a detailed guide to each component, including technologies and best practices, with short code snippets to illustrate core functionalities.

Frontend Technologies and UI/UX Considerations

A modern, responsive front-end is critical for an online car marketplace. Most successful platforms use dynamic JavaScript frameworks to deliver an app-like, seamless user experience on web and mobile:

Frameworks & Languages: According to industry tech stacks, popular choices for building marketplace frontends include React, Angular, or Vue.js (often combined with TypeScript for robustness) (Codica). These frameworks allow you to create a rich interactive UI where users can filter searches, view image galleries, and complete transactions without constant page reloads. For example, Carvana’s site heavily uses React for its dynamic content.
Responsive Design: Ensure the UI is mobile-friendly and works smoothly on all screen sizes. As per my research, a significant portion of users will browse car listings on smartphones. Use responsive layouts (CSS flex/grid or responsive frameworks) so that search filters, car images, and checkout flows adapt to different devices.
Intuitive Navigation & Search UI: The frontend should make it easy for users to find what they need. Implement prominent search bars and filter menus on listing pages. For example, include dropdowns or sliders for price range, make/model, year, mileage, etc.
High-Quality Imagery & Visualization: Since car buying is highly visual, prioritize displaying high-quality photos and videos on the front-end. Implement a carousel or gallery component for listings, enabling users to scroll through images. Carvana, for example, offers a 360° photo viewer for each car (Snappr).
Separate Interfaces for Different Users: Design the frontend with role-specific experiences. For instance, buyer vs. seller dashboards should surface different options. A buyer might see their saved cars, purchase history, and financing offers, whereas a seller (or dealer) would see tools to manage their listings and leads.
UI/UX Best Practices: Keep the overall design clean and fast. Use a consistent color scheme and branding (your logo, etc.) to build trust. Active voice copy and clear calls-to-action (e.g., “Browse Cars”, “List Your Car”) guide users.

Backend Development and APIs

The back-end is the engine powering your marketplace – it handles the business logic, database operations, and integrations with external services. When building from scratch, you’ll likely create a RESTful API (or GraphQL) that the front-end can communicate with. Key considerations for the back-end include choosing a tech stack, structuring the database, and implementing core functionalities like listings, authentication, and transactions.

Tech Stack & Frameworks

Common back-end technologies for marketplaces include Node.js (JavaScript) or Python or Ruby on Rails, among others. For instance, one development team noted using Ruby on Rails or Node/Nest.js for building a car marketplace backend (Codica). The choice depends on your team’s expertise.

Database Design

You’ll need a database to store information about cars, users, orders, etc. Relational databases like PostgreSQL or MySQL are a great fit for structured data (cars, users, transactions), and they support complex queries (e.g., searching cars by multiple criteria). Many marketplace builders use Postgres or MySQL, often alongside caching or search engines.

Core Backend Features

The backend must implement all the logic for features we’ll outline in the next section. This includes:

Listing Management: Endpoints to create, read, update, and delete car listings.
Search & Filter: A search API that takes query parameters (make, model, price_min, price_max, etc.) and returns matching cars.
User Authentication & Accounts: Registering new users, logging in, password hashing, issuing auth tokens.
Transactions & Payments: Integration with payment gateways (e.g., Stripe) to handle credit card transactions.
Third-Party Integrations: Vehicle history APIs (e.g., Carfax, AutoCheck) and maps/geolocation services.

Example – Listing Cars API

To illustrate a simple backend component, here’s a code snippet of a Node.js (Express) route that returns a list of car listings from a MongoDB database:

// Example: Express.js route to get all car listings
const express = require('express');
const app = express();
const Car = require('./models/Car');  // Mongoose model for Car

app.get('/api/cars', async (req, res) => {
  try {
    // Fetch all car listings (in real app, add filters, pagination, etc.)
    const cars = await Car.find({});
    res.json(cars);
  } catch (err) {
    res.status(500).json({ error: err.message });
  }
});

In a production setting, you’d likely add query parameters for filters (e.g., /api/cars?make=Toyota&price_max=20000), and translate those into database query conditions. Also, you’d implement pagination (limit & offset) to avoid returning too many records at once.

Server-Side Architecture, Scaling and Security

When building a platform from scratch, it’s wise to set up a scalable server architecture that can grow with your user base. Early on, an MVP can be deployed on a single server, but you should design with scalability and security in mind. Here are some best practices:

Cloud Hosting

Most modern startups deploy on cloud platforms like AWS, Microsoft Azure, or Google Cloud Platform. According to one guide, typical infrastructure choices for marketplaces include AWS or similar providers (Codica).

Microservices vs Monolith

In the beginning, a monolithic architecture is simpler and faster to build. However, design it in a modular way so that you can split services out later if needed. As your platform grows, you might evolve toward a microservices architecture.

DevOps and Deployment

Embrace modern DevOps practices:

Use Docker containers to package your app
Tools like Kubernetes or Docker Compose for container management
CI/CD pipeline (Jenkins, GitHub Actions) for automated testing/deployment
Monitoring tools for performance tracking

Scaling Considerations

As more users and listings come in:

Use Load Balancers (AWS ELB) to distribute traffic
Scale databases vertically or horizontally
Implement caching via Redis or Memcached
Use CDNs for image delivery (AWS CloudFront, Cloudflare)
Scale search services (ElasticSearch) separately

Security Best Practices

Critical security measures include:

Secure Communication: HTTPS (SSL/TLS) for all traffic
Authentication:
- Hash passwords (bcrypt)
- Use JWTs for sessions
- Role-based access control
Data Protection:
- Database security/firewalls
- Encrypt sensitive data at rest
- PCI DSS compliance for payments
Fraud Prevention:
- Email/phone verification
- Manual review of suspicious listings
- Activity monitoring
- Escrow payments (DevTechnosys)
Regular Audits:
- Software updates
- Security audits
- Compliance (GDPR, CCPA)

Cost Considerations

You can start small (even a single $50/month server for MVP) and scale as needed. The key is making architectural decisions that allow for future growth while maintaining security from day one.

Essential Features and Functionality

Building a used car marketplace involves satisfying the needs of multiple user groups. A successful marketplace “really knows consumer expectations and demands” (Codica). Here are the must-have features:

Features for Private Sellers (Individuals Listing Their Car)

On the other side, if you allow private owners to sell their used cars through your marketplace (like an individual selling to another individual or to a dealer), you must cater to their needs. Sellers are essentially your “suppliers,” and attracting them means making the listing process as easy and rewarding as possible (Eastern Peak). Key features for sellers include:

Easy Listing Creation Wizard: Provide a step-by-step, user-friendly process to list a car for sale. Many sellers are not tech-savvy, so simplify it: for example, after clicking “Sell Your Car,” walk them through a form that asks for the vital details:

Car Details: VIN (Vehicle ID Number) lookup (to auto-fill year/make/model), or manual entry of make, model, year. Then fields for mileage, condition, color, etc.
Photos Upload: Prompt the seller to upload clear photos. Allow multiple uploads at once and indicate recommended shots (front, side, interior, odometer reading, etc.). Possibly integrate a drag-and-drop or mobile photo upload directly. High-quality images are crucial since “visuals greatly influence a buyer’s interest” (Codica).
Pricing: Ask the seller’s desired price. If possible, assist them with a pricing tool – e.g., show an estimated market value range for their car based on data (like KBB value or your marketplace’s recent sales). This helps them set a competitive price.
Description: Encourage a text description for any unique selling points or disclosures.
Contact & Verification: Possibly verify their phone/email if not done already, and let them publish the listing.

Listing Management Dashboard: Once listed, sellers should have a personal dashboard to manage their listings (Codica). This includes:

Viewing all their active listings (with status: active, pending, sold).
The ability to edit details or add more photos if needed.
Option to update the price (maybe they want to lower it if it’s not selling).
A way to mark the car as Sold (if sold outside the platform or to a platform lead).
If your platform requires approval for listings, show if it’s under review.
Stats: It’s motivating to show sellers some analytics, like how many views or inquiries their listing has gotten.

Secure Messaging and Leads: Sellers should be able to receive and respond to buyer messages or offers through the platform’s messaging system. In their dashboard or via notifications, alert them when a new inquiry comes in: e.g., “You have a new message from an interested buyer.”

Trust and Verification for Sellers: To create trust for buyers, you may implement seller verification badges. For example, after a seller submits a listing, maybe you verify their phone number or ID and then show a “Verified Seller” badge on their profile/listing.

Multiple Listing Options: If you cater to both private sellers and dealers, delineate that in the UI. Perhaps during listing, ask “Are you a private owner or a dealer?” and adjust the flow accordingly.

Fast Listing Approval: If you manually review listings for quality or fraud, try to approve them quickly (within hours). Sellers appreciate a quick turnaround.

Notifications for Sellers: Keep sellers informed. For example:

Notify when their listing goes live (“Your car is now listed!”).
If a listing is about to expire (if you have time-limited listings), remind them to renew it.
If they get an offer or message, as mentioned.
If someone saves or “favorites” their car.
Weekly summaries: “Your listing had 100 views this week.”

Seller Protections: Although buyers are the ones spending money, consider features that protect sellers too. For instance, if transactions go through the platform, ensure that the payment is verified before telling the seller to hand over the car.

In summary, private sellers want a quick and easy way to turn their car into cash. By offering a smooth listing process, control over their listings, and a way to communicate with potential buyers, you lower the barrier for people to use your platform instead of trading in or using another site. As one source suggests, providing “fast upload tools for private sellers” is key, whereas dealers might need bulk tools (Codica). We turn to dealer-specific needs next.

Features for Dealers and Dealerships

Professional car dealers (used car dealerships or even new car franchise dealers with used inventory) can be important users of your marketplace. Many online car platforms generate revenue by serving dealers who want to list their inventory to a large audience. If your business model includes dealers, you should build features that cater to them:

Dealer Accounts and Inventory Integration

Special dealer account type with dealership profile (name, location, logo)
Bulk upload capabilities (CSV imports, API integration with dealership management systems)
Mass listing tools for high-volume inventory (Codica)

Dealer Dashboard and Analytics

Centralized inventory management
Performance analytics (views, leads, conversion rates)
Lead management system with CRM integration
Account billing and subscription management
Team access for multiple salespeople

Special Listing Features

Verified dealer badges for licensed dealerships
Enhanced media options (video tours, YouTube embeds)
Virtual appointment scheduling tools
Live chat functionality for real-time buyer engagement

Dealer Subscriptions and Packages

Tiered subscription plans (free/premium tiers)
Listing limits enforcement based on plan level
Online plan upgrade functionality
Recurring payment integration

Location and Geotargeting

Advanced location-based search filters
Regional service area definitions
Multi-country support for international markets
Service availability indicators (delivery range, shipping options) (Eastern Peak)

Trust and Compliance Tools

Automated compliance documentation (Buyer’s Guide templates)
VIN-based vehicle history report integration
Standardized disclosure requirements

Communication & CRM Integration

Flexible lead delivery options (in-platform, email, API)
SMS lead generation capabilities
CRM system synchronization

Featured Dealer Listings and Ads

Paid priority placement in search results
Promoted inventory slots
Banner advertising opportunities
Sponsored listing capabilities

In short, dealers want bulk management, insights, and ways to reach more buyers. By building dealer-specific functionality, you not only enhance their experience but also create monetization avenues (through subscriptions or advertising). As noted in one source, the platform should cater to both dealers and private sellers, offering different features to suit their needs (DevTechnosys). Many car marketplaces attribute a large part of their inventory (and revenue) to dealer listings, so it’s wise to make your platform dealer-friendly from the start, even if you launch small.

Admin Features (Platform Administration)
Behind the scenes, your team will need an admin panel (administrator backend) to oversee the marketplace’s operations. This is not customer-facing, but it’s crucial for maintaining quality, security, and smooth transactions. Essential admin capabilities include:

User Management: As an admin, you should be able to view and manage all user accounts (buyers, sellers, dealers). This means an interface to search users, see their details and activity, reset passwords or force email verification if needed, and ban or suspend accounts that violate policies.

Listing and Content Moderation: The admin panel should list all vehicle listings with the ability to filter by status (pending approval, active, reported, etc.). Admins can then review new listings (to approve or reject them). They should also see flags or reports – e.g., if users report a listing as fraudulent or offensive, it pops up for review. The admin needs to be able to “check listings and observe user activity” efficiently (Eastern Peak).

Transaction Oversight: If transactions (payments) happen through your platform, provide an interface to monitor these. For example, show a list of recent purchases, their status (paid, in escrow, released, refunded).

Dispute Resolution Tools: Occasionally, buyers and sellers may get into disputes (e.g., a buyer claims the car wasn’t as described). Your admin backend should allow you to intervene.

Analytics Dashboard: Having a bird’s-eye view of platform metrics helps you make decisions. Build an admin dashboard that shows stats like:

Number of active listings, new listings today
User signups per day
Total sales through platform (if applicable)
Most popular search queries or car models
Revenue figures (from fees, etc.)

Content Management (CMS): If your marketplace has content beyond listings – such as a blog, FAQs, or marketing pages – having an admin CMS to edit those pages is useful.

Notification and Email Tools: Give admins the ability to send out notifications or emails to users. For example, a broadcast message: “We will have maintenance at midnight” or a promotional email to all users about a new feature.

System Configurations: A section for adjusting config options like pricing of fees, feature flags to turn on/off certain features, etc., can be handy.

Security & Audit Logs: An admin should also have access to logs of important events (who logged in, failed payments, etc.). In case of malicious activity, these logs help track what happened.

Overall, the admin panel is your command center to keep the marketplace healthy. It should allow you to ensure quality control, support users, and adapt settings without needing a developer for every little change. Research underscores that an efficient admin dashboard is needed for checking performance and resolving disputes on the marketplace. As you build from scratch, don’t neglect admin tools – they will save you immense time managing the platform and scaling your operations.

User Account Management Features

Account management spans across all user types (buyers, sellers, dealers) and is fundamental to the platform’s security and personalization. These features deal with how users sign up, log in, and control their profile and settings. Key account management features include:

User Registration & Login

Simple signup process (email + password with verification)
Social login options (Google, Facebook)
Email verification to reduce fake accounts
Separate dealer onboarding with additional verification
CAPTCHA or email confirmation for bot prevention
Optional two-factor authentication (2FA) for security

Profile Management

Basic info (name, contact details, location)
Additional fields for sellers/dealers (business info, VAT numbers)
Profile avatar/photo upload capability
Credibility indicators (verification badges, ratings, transaction history) (Codica)

Account Dashboard

Buyer dashboard (saved cars, inquiries, purchase history)
Seller dashboard (current listings, performance stats)
Unified account settings (profile edit, password change, notifications)
Control panel for all user activities

User Authentication & Security

Secure password storage (bcrypt with salted hashes)
Email confirmation for sensitive changes
Login attempt rate-limiting
Secure session management (httpOnly cookies/JWT tokens)

Password Recovery

“Forgot Password” flow with secure reset tokens
In-account password change capability
Balanced password complexity requirements

Privacy Controls

GDPR-compliant data management
Account deletion requests
Marketing email opt-in/out preferences
Data download capability

Activity History

Buyer viewing history (searches, viewed cars)
Seller activity logs (listing changes)
Transaction history visibility
Internal action tracking

Example – User Authentication Code
Simplified Node.js/Express JWT login implementation:

// Example: User login endpoint (Node.js/Express)
app.post('/api/login', async (req, res) => {
  const { email, password } = req.body;
  const user = await User.findOne({ email });
  if (!user || !user.checkPassword(password)) {
    return res.status(401).json({ error: 'Invalid credentials' });
  }
  // Create a JWT token (with user id and role claims)
  const token = createJwtToken({ userId: user._id, role: user.role });
  res.json({ token });
});

Cost Estimation for Building the Platform

Building a full-fledged car marketplace like Carvana from scratch is a significant undertaking. Here’s a detailed cost breakdown considering development, infrastructure, maintenance, and marketing. As per my research, estimates for custom car marketplace platforms range from tens of thousands to a few hundred thousand dollars in development alone (Depex Technologies).

Development Costs (Design & Build)

Feature Scope and Complexity

Basic MVP (user accounts, simple listings, search, basic payments): 30k−30k−60k
Advanced platform (e-commerce, 360-tours, financing integrations): $100k+
Industry estimates range from 35,000to35,000to250,000+ depending on features (Depex Technologies)

Design (UI/UX)

Professional UI/UX design: 5k−5k−15k (web only)
Mobile app design adds to cost
Sample allocation: 56 hours UX + 64 hours UI at 50/hour= 50/hour= 6k

Development Team & Hours

North America/Western Europe rates: 50−50−150/hour
Eastern Europe/India rates: 20−20−50/hour
MVP development typically requires 2000-3000 hours
Example: 2000 hours at 50/hr=50/hr=100k (DevTechnosys)

Platform (Web vs Mobile)

Responsive web app covers basic needs
Native mobile apps (iOS/Android) can double frontend costs
Basic single-platform app: 10k−10k−25k
Comprehensive apps significantly more

Third-Party Services and Licensing

Vehicle history checks (Carfax, etc.) – pay-per-use
Map services beyond free quotas
Development tools/project management software: few hundred/month
API integration costs for payments, etc.

Summary of Development Cost: Taking all these into account, here’s a possible scenario:

Basic MVP (few core features, web-only): ~$30,000–$60,000 (assuming a small team 3-6 months of work).
Full-featured platform (web + mobile, many integrations): $100,000–$200,000 (could be 6-12+ months of development).
High-end, Carvana-scale (robust, highly polished, perhaps with emerging tech like AI): $250,000 or more.

Cost Variability
These numbers can fluctuate. If you are savvy and use off-the-shelf components (like an existing marketplace software or open-source code to bootstrap), you might lower dev costs. Conversely, if you hire a top-tier agency in an expensive city, costs could exceed these ranges. It’s wise to start with a clear list of features (a MVP feature set) and get quotes. Also, building incrementally (launch basic, then iterate) can spread costs over time.

Infrastructure and Hosting Costs

Infrastructure refers to the servers, cloud services, and other tech resources needed to run the platform. Unlike development, which is an upfront project cost, infrastructure is an ongoing expense (usually monthly) but will grow with your user base.

Hosting Servers

Basic cloud setup: ~$50/month (ServerMania)
Example: 8GB RAM, 2 CPU server on AWS/DigitalOcean
Separate servers for database, application, search services
Early stage: few hundred dollars per month

Scaling Costs

Medium architecture: few thousand dollars/month
Production database service (AWS RDS): 500–500–1000/month
CDN costs (~$0.10/GB after free tier)
Millions of visits: significantly higher cloud costs

Storage & Backup

Cloud storage (AWS S3): ~$0.023/GB/month
Example: 10,000 listings with 50MB images = 500GB (~$12/month)
Database backups: 50–50–100/month

Domain, SSL, and Misc.

Domain registration: $10-20/year
SSL certificates: free to $100/year
Transactional email: $10-20/month
SMS verification: few cents per message

Maintenance and Ongoing Development

Launching the platform is just the beginning; ongoing maintenance and support are needed to keep it running smoothly and to add improvements.

Bug Fixes and Updates

Routine maintenance: 1,000to1,000to5,000 per month (Depex Technologies)
Includes updates, small feature tweaks, server monitoring
Higher costs in initial months post-launch

Scaling and Optimization

Performance optimization
Infrastructure scaling
DevOps support: $500+/month

Customer Support

Founders handle initially
Dedicated support rep as you scale
Helpdesk software: $50-100/month

Continuous Development

Quarterly feature releases
Recommendation engines, mobile apps, etc.
Funded through revenue or investment

Security and Compliance

Security patches and certificate renewals
Yearly security audit: 5k−5k−10k
Compliance updates as laws change

Maintenance Budget

Recommended 15-20% of initial development cost/year
Example: 100kdevelopment=100kdevelopment=15-20k/year (~$1.5k/month)

Marketing and Go-to-Market Costs

Building the marketplace is one half; marketing it to buyers and sellers is the other half. Marketing costs can vary widely depending on strategy, but let’s break down some typical expenses:

Digital Advertising

Online ads (Google, Facebook/Instagram)
Initial campaigns: 5,000−5,000−100,000+ (Business of Apps)
Example: $5k test campaign in one city
Digital channels more cost-effective than traditional media

Content Marketing & SEO

Blog posts, guides, video content
Outsourced content creation: few hundred dollars per article
Monthly budget: 1k−1k−2k for content creation
Long-term organic traffic benefits

Organic social media management
Part-time social media manager: 500−500−1,000/month
Contests and referral programs
Community building strategy (VoyMedia)

Promotional Material

Traditional marketing (flyers, car shows)
Local event sponsorships
Printing costs: few hundred dollars
Event sponsorships: thousands

PR (Public Relations)

Press coverage in tech blogs/local news
PR agency: 2k−2k−5k for launch campaign
Alternative: free platforms like HARO

Incentives

Seller incentives (free listings, gift cards)
Referral bonuses ($20 per referral)
Early-stage liquidity building

Launch Event

Optional local launch event
Venue and refreshments: ~$1k
Press conference/demo day

Given these, a go-to-market budget could reasonably be in the low five figures at launch (say $10k-$20k) to get initial traction (ads + content + PR). Then ongoing marketing might be a few thousand a month, scaling up if results are good. For context, some app launches spend relatively modestly, while others go big; industry data shows app marketing launch budgets can range up to $100k and beyond for competitive spaces. Since the used car market is competitive, be prepared that customer acquisition might be costly. However, creative strategies (SEO, partnerships) can mitigate some direct spend by leveraging organic growth.

Cost Recap: Putting it all together:

Development: e.g., $50k for MVP (upfront).
Infrastructure: e.g., $200/month at start, scaling to $1000+/month as we grow.
Maintenance: e.g., $2k/month for ongoing improvements and support.
Marketing: e.g., $10k launch budget, then $3-5k/month in various campaigns (scaling with user growth).

This is a hypothetical mid-range scenario. Always remember to adjust these estimates to your specific context (maybe you have an in-house tech co-founder, reducing dev cost; or perhaps you plan a slow growth so lower marketing spend). If you target both US and Europe from the start, marketing and compliance costs might double as you’re essentially launching in two markets with different tactics.

Lastly, it’s prudent to have a contingency in your budget (10-20%) for unplanned expenses (maybe a needed feature you didn’t initially consider, or legal fees for compliance adjustments).
