Launching a website for a US business is straightforward, but there are a handful of requirements that are easy to overlook and awkward to fix later — from accessibility and privacy to sales tax and payment setup. This checklist covers the essentials every US business website should have, in plain language, so you launch on solid ground rather than discovering a gap after go-live.
None of this is complicated, but skipping it can mean legal headaches or lost customers. Here's what actually matters for a US site.
The requirements that trip US businesses up aren't the flashy features — they're accessibility, privacy, and tax. Get the boring essentials right and the rest is easy.
Legal and compliance essentials
- Accessibility (ADA): your site should be usable by people with disabilities — a legal and ethical must, and increasingly litigated.
- Privacy policy: required if you collect any personal data, and expected by customers.
- Privacy laws: rules like California's CCPA may apply depending on where your customers are.
- Terms and clear contact info: including a real business address and way to reach you.
If you sell online
US sales tax is the big one, and it's genuinely complex — rates and rules vary by state, and you may owe tax in states where you have "nexus." Your store needs to calculate sales tax correctly based on where your customers are, so use a platform or tool that automates this. Pair it with reliable US payment processing and clear pricing in dollars.
The fundamentals that apply everywhere
Beyond US-specific items, the universal essentials still matter most for actually winning business: mobile-friendliness, fast loading, security with HTTPS, clear messaging, and a strong call to action. A compliant site that's slow or confusing still won't bring in clients, so don't let the checklist distract you from the basics — see why websites don't get clients.
A quick launch checklist
Before you go live: accessible design, privacy policy, HTTPS, mobile-friendly and fast, clear contact details, and — if you sell — automated sales tax and reliable payments. Tick those and you've covered what most US small businesses need. This isn't legal advice, so check anything specific to your situation with a professional.
Frequently Asked Questions
What does a US business website legally need?
The main essentials are an accessible design usable by people with disabilities (ADA), a privacy policy if you collect any personal data, awareness of privacy laws like California's CCPA, and clear terms and contact information. If you sell online, you also need correct sales tax handling. This isn't legal advice, so confirm specifics for your situation with a professional.
Does my website need to be ADA accessible?
You should treat accessibility as a requirement. Making your site usable by people with disabilities is both an ethical standard and increasingly a legal one, with accessibility lawsuits becoming more common. Following recognised accessibility guidelines during design and build is far easier than retrofitting later, and it also improves usability for all of your visitors.
How does US sales tax work for an online store?
US sales tax is complex because rates and rules vary by state, and you may owe tax in states where you have a connection, or nexus. Your store must calculate the correct tax based on where each customer is. The practical solution is to use a platform or tool that automates sales tax calculation rather than trying to manage it manually.
Do I need a privacy policy on my US website?
Yes, if you collect any personal data — which most sites do through contact forms, analytics, or sales. A clear privacy policy explaining what you collect and how you use it is expected by customers and required under various privacy laws. Depending on where your customers live, rules like California's CCPA may impose additional requirements you need to meet.
What's the most overlooked US website requirement?
Accessibility and sales tax are the two most commonly overlooked. Businesses often focus on design and features while forgetting that their site must be usable by people with disabilities and, if selling, must handle multi-state sales tax correctly. Both are awkward to retrofit, so building them in from the start saves real trouble and expense later.
Do compliance requirements matter more than good design?
Both matter, but don't let compliance distract you from the basics that win business. A fully compliant site that's slow, confusing, or not mobile-friendly still won't bring in clients. Cover the legal essentials, then focus on speed, clear messaging, and a strong call to action — because those are what actually turn visitors into customers.
