• Obtain necessary licenses and permits (sales tax, business licenses, special permits)
• Follow zoning rules for your business location

Policies and Consumer Protection

• Create clear terms of service and privacy policy
• Get customer consent for data collection
• Follow consumer protection laws (FTC regulations, COPPA, advertising guidelines)
• Provide accurate product information, pricing, and policies

Intellectual Property and Copyright

• Register trademarks and copyrights
• Obtain licenses for third-party content
• Prevent counterfeit product sales

Secure Payment Processing

• Use a secure payment gateway (PCI DSS certified)
• Implement security measures (encryption, two-factor authentication, tokenization)

Stay Compliant

• Monitor legal changes and update practices accordingly
• Seek expert advice from lawyers and industry professionals

This is a checklist, not legal advice. Rules differ by state and by what you sell, and the cost of getting one of these wrong is high enough to justify an hour of a lawyer’s time.

Intellectual Property	Trademarks, copyrights, licenses, anti-counterfeiting
Secure Payments	Secure gateways, data protection, breach response
Shipping & Taxes	Shipping regulations, clear policies, sales tax
Website Accessibility	ADA, WCAG guidelines, accessible design
Staying Compliant	Monitoring legal changes, expert guidance

Setting Up Your Business

Register Your Business

To start, you need to choose a business structure. Options include:

• Sole proprietorship
• Partnership
• Limited liability company (LLC)
• Corporation

Each has pros and cons, so research them carefully before deciding.

Next, register your business with state or local authorities. This usually involves:

• Filing articles of incorporation or organization
• Getting an Employer Identification Number (EIN) from the IRS

Get Licenses and Permits

Depending on your products and location, you may need:

• Sales tax permits
• Business licenses
• Special permits (e.g., for food or pharmaceuticals)

Check with your state or local government for requirements.

Follow Zoning Rules

Zoning laws control how properties can be used in an area. Make sure your business location follows these rules.

You may need to:

• Get a zoning permit
• Obtain a zoning variance

Business Setup Step	Key Points
Register Business	– Choose business structure (sole proprietorship, partnership, LLC, corporation) – File articles of incorporation/organization – Get Employer Identification Number (EIN)
Get Licenses/Permits	– Sales tax permits – Business licenses – Special permits (e.g., food, pharmaceuticals) – Check state/local requirements
Follow Zoning Rules	– Ensure location complies with zoning laws – May need zoning permit or variance

Properly setting up your business from the start helps ensure legal compliance and avoid potential issues down the road.

Terms and Privacy Policies

Having clear terms of service and a privacy policy is vital for your e-commerce business. These documents explain the rules, rights, and responsibilities for your business and customers.

Write Terms of Service

A terms of service agreement is a contract between your business and customers. It outlines the rules for using your website and services. It should cover:

• How customers accept the terms
• Your business name, address, and contact details
• The products or services you offer
• How customers can make payments and accepted payment methods
• When customers can cancel purchases and get refunds
• Which laws govern the agreement and how disputes will be resolved
• How you’ll notify customers of changes to the terms

A clear terms of service agreement protects your business and customers, ensuring a positive and secure online shopping experience.

Create a Privacy Policy

A privacy policy outlines how your business collects, uses, and protects customer data. It should cover:

• Types of personal data collected (e.g., names, addresses, payment details)
• How personal data is used (e.g., marketing, order fulfillment)
• Parties that may access customer data (e.g., payment processors, shipping providers)
• Measures taken to secure customer data (e.g., encryption, access controls)
• How customers can access, update, or delete their personal data

A privacy policy that describes what you actually do is worth having. One copied from a generator that describes practices you do not follow is worse than none, because it is a written statement you can be held to.

Get Customer Consent

To comply with data privacy laws like GDPR and CCPA, you must handle consent properly before collecting personal data. Note that the two regimes differ: GDPR generally requires an opt-in lawful basis, while CCPA is built around a right to opt out of the sale or sharing of personal information. This can be achieved through:

Consent Method	Description
Clear Language	Using simple, easy-to-understand language in your privacy policy and terms of service
Opt-in Mechanisms	Providing customers with opt-in options for data collection and use, such as checkboxes or buttons
Transparency	Clearly explaining how customer data will be used and protected

Consumer Protection and Advertising

Follow Consumer Protection Laws

In the U.S., the Federal Trade Commission enforces the main rules that apply to online selling:

• Section 5 of the FTC Act: prohibits unfair or deceptive acts or practices. This is the statute usually meant when marketing material refers to “UDAP” – it is not a separate rule, and there is no federal statute called the Consumer Protection Act. An earlier version of this checklist listed both as if they were distinct laws; that was wrong and has been corrected.
• The Children’s Online Privacy Protection Act (COPPA): sets rules for collecting personal information from children under 13.
• State UDAP statutes: every state has its own version, and they are often stricter than federal law. If you ship nationwide, these are what you will actually be sued under.

Ensure Truthful Ads

Ads must be accurate and not misleading. E-commerce businesses should:

• Clearly disclose product features and benefits.
• Avoid false claims about products or services.
• Provide clear information about products, services, and any risks or limitations.
• Disclose material connections in reviews, endorsements, and influencer posts, which the FTC treats as advertising.

Provide Clear Information

Customers need clear, transparent details to make informed purchases. E-commerce sites should:

Information to Provide	Details
Product Pricing	Clearly list product prices and any additional fees.
Product Descriptions	Detailed specifications and descriptions of products.
Shipping Policies	Outline shipping costs, methods, and estimated delivery times.
Return/Refund Policies	Clear policies on returns, refunds, and any associated fees.

Hidden fees revealed at checkout are the most common version of this failure, and several states now regulate them directly.

Intellectual Property and Copyright

Register Trademarks and Copyrights

Registering trademarks and copyrights protects your business’s intellectual property. Trademarks safeguard your brand identity, like logos, slogans, and business names. Copyrights protect original works, such as website content, product descriptions, and images.

To register a copyright:

1. Submit a completed application 2. Provide a copy of the material to copyright 3. Pay a filing fee

How long this takes depends on how you file. The U.S. Copyright Office publishes its current processing times: online applications with a digital deposit average about 3.6 months when no correspondence is needed, rising to around 5 months when the examiner has questions, while paper filings average over 6 months and can run much longer. Registration is not what creates the copyright – that exists from the moment the work is fixed – but you generally need it before you can sue in the U.S.

Get Necessary Licenses

When using third-party content on your website, ensure you have the proper licenses or permissions. This includes images, videos, music, and other digital content. Stock photo licences in particular have limits on commercial and print use that people routinely ignore. Verify the licensing terms for any third-party content you use, and keep the licence record.

Prevent Counterfeit Sales

To prevent counterfeit or pirated goods from being sold on your platform, take these steps:

• Verify the authenticity of products before listing them
• Monitor your platform for suspicious activity
• Respond promptly to customer complaints about counterfeit products
• Collaborate with law enforcement and intellectual property owners to address counterfeit issues

Action	Purpose
Verify product authenticity	Prevent listing counterfeit goods
Monitor platform activity	Identify suspicious listings or sellers
Respond to customer complaints	Address counterfeit product issues
Collaborate with authorities	Work with law enforcement and IP owners

Secure Payment Processing

Handling customer payments securely is crucial for e-commerce businesses. Follow these steps to protect payment information and prevent fraud.

Use a Secure Payment Gateway

Choose a payment gateway that meets PCI DSS (Payment Card Industry Data Security Standard). PayPal, Stripe, and Square all handle card data on their own infrastructure, which is the point: if card numbers never touch your server, your own PCI scope shrinks dramatically. Building your own card handling to save on transaction fees is almost always a bad trade for a small merchant.

Implement Security Measures

Protect customer payment data with these security measures:

• Encryption: Use SSL/TLS encryption to secure data transfer between customer browsers and your server.
• Two-Factor Authentication: Require two-factor authentication on your admin and payment accounts.
• Tokenization: Replace sensitive payment details with a unique token to reduce data breach risks.
• Security Audits: Regularly check for vulnerabilities and address them promptly.

Prepare for Data Breaches

Have a plan ready in case of a data breach. All 50 states have breach notification laws with their own deadlines, so the plan needs to name who decides and how fast.

Action	Details
Notify Customers & Authorities	Inform customers and relevant authorities about the data breach.
Incident Response Plan	Develop a plan to quickly respond and minimize damage.
Customer Support	Provide support to address customer concerns and questions.

Shipping and Customs Rules

Understand Shipping Regulations

Different countries have varying rules for shipping items. You must follow these regulations to avoid legal issues and ensure smooth delivery to customers. For example, there are strict rules for shipping hazardous materials, including proper packaging, labeling, and documentation. Lithium batteries catch out more small sellers than anything else on that list.

Provide Clear Shipping Information

Be transparent about shipping costs, delivery times, and any customs duties or taxes. Customers dislike unexpected fees or delays, so set clear expectations upfront. You can:

• Negotiate rates with shipping providers
• Choose appropriate packaging
• Consolidate shipments
• Use hybrid shipping services

This can help reduce shipping costs.

Collect Sales Tax

Your e-commerce platform should calculate and collect the correct sales tax based on the customer’s location. Since the Supreme Court’s 2018 South Dakota v. Wayfair decision, states can require sales tax collection from sellers with no physical presence there, subject to each state’s economic nexus thresholds. Track your sales by state, because crossing a threshold creates an obligation whether or not you noticed.

Shipping Requirement	Key Points
Understand Regulations	Follow rules for prohibited items, agricultural regulations, packaging, labeling, customs processes, and required documents.
Provide Clear Info	Communicate shipping costs, delivery times, and customs duties/taxes upfront to set expectations.
Collect Sales Tax	Calculate and collect the correct sales tax based on the customer’s location to comply with laws.

Making Your Website Accessible for Everyone

Create an Accessible Website

It’s important to make your e-commerce website accessible so that all customers, including those with disabilities, can use it easily. This includes adding features like:

• Alternative Text for Images: Screen readers can describe images to visually impaired users.
• Keyboard Navigation: Users who can’t use a mouse can navigate with a keyboard.
• Screen Reader Compatibility: Visually impaired users can access content with screen readers.

Here are some additional tips for an accessible website:

• Use clear and consistent navigation menus
• Provide closed captions for audio and video
• Ensure all content works with assistive technologies

Follow ADA Guidelines

Be precise about what the law says here, because a lot of accessibility marketing is not. The Department of Justice’s 2022 guidance states that the ADA applies to the web content of businesses open to the public, but it does not adopt a specific technical standard for them. The 2024 final rule that mandates WCAG 2.1 Level AA applies to state and local government entities under Title II, not to private online retailers. In practice, private sellers are exposed through private lawsuits rather than a regulator’s checklist, and courts have treated WCAG as the de facto benchmark.

What that means for you:

• Use the Web Content Accessibility Guidelines (WCAG 2.1 AA) as your reference standard, because it is what a plaintiff’s expert will use
• Regularly check for and fix accessibility issues
• Provide a website accessibility statement with a contact route for people who hit a barrier
• Include “skip navigation” links and proper heading tags on all pages

Be sceptical of overlay widgets sold as instant ADA compliance. They have not reliably prevented lawsuits and accessibility practitioners generally advise against them.

Accessibility Feature	Purpose
Alternative Text	Describes images for visually impaired users
Keyboard Navigation	Allows navigation without a mouse
Screen Reader Compatibility	Enables access for visually impaired users
Closed Captions	Provides audio/video transcripts
“Skip Navigation” Links	Helps users bypass repetitive content
Proper Heading Tags	Organizes content for screen readers

Stay Up-to-Date

Laws and rules for e-commerce businesses change frequently. Keeping track of these updates avoids unpleasant surprises.

Monitor Legal Changes

Regularly check for new laws and regulations related to:

• Consumer protection
• Data privacy
• Taxation

State privacy laws are the fastest-moving area. More than a dozen states now have comprehensive privacy statutes with different thresholds and rights, so “we comply with CCPA” stopped being a complete answer some time ago.

Seek Expert Advice

If you’re unsure about legal requirements, consult a lawyer who works with online sellers. The two areas where paid advice reliably pays for itself are multi-state sales tax registration and any product category with its own regulator, such as food, supplements, cosmetics, or anything medical.

Action	Purpose
Monitor Legal Changes	Stay informed about new laws and regulations
Adjust Business Practices	Ensure compliance with the latest rules
Seek Expert Advice	Get guidance on complex legal requirements

Conclusion

Following this checklist protects your e-commerce business from legal trouble. Compliance is ongoing rather than a one-time project, because the rules keep moving.

Online sellers face obligations across consumer protection, data privacy, intellectual property, accessibility and tax. Non-compliance leads to fines, lawsuits, operational disruption, and reputational damage. Most of the checklist above is cheap. The expensive part is discovering an obligation after you have breached it.

Practical priorities:

• Track sales by state so you know when you cross an economic nexus threshold
• Make sure your published privacy policy matches what your site actually does
• Fix the accessibility basics: alt text, keyboard navigation, headings, contrast
• Get advice on any product category with a specific regulator
