Top 5 Contracts Every E-Commerce Business Needs

E-commerce looks simple from the outside — list a product, take an order, ship it — but underneath every store is a web of relationships that can each turn into a dispute: suppliers who don't deliver, customers who chargeback, contractors who built your site, and platforms that hold your account. After 20 years litigating business disputes, I've seen online sellers get blindsided not by their product but by the paperwork they never put in place around it. Here are the five contracts every e-commerce business needs, and what each one is quietly protecting you from.

1. Website terms of service and purchase terms

Your storefront is a contract with every customer, whether you wrote one or not — so write one. Clear terms of service and purchase terms govern the sale itself: what the customer is buying, your refund and return policy, shipping and delivery expectations, limitations on your liability, and how disputes get handled. This is your first line of defense against the customer who claims they were promised something you never offered, or who wants to reverse a sale on terms you never agreed to. Well-drafted purchase terms set expectations up front and give you something concrete to point to when a transaction goes sideways. Without them, every dispute is your word against the customer's, decided by default rules you didn't choose.

2. A supplier or manufacturer agreement

Your business depends on other people delivering goods on time, at the promised quality, at the agreed price — and a handshake with a supplier is a risk to your entire operation. A supplier or manufacturer agreement defines quantities, quality standards, timelines, pricing, what happens when a shipment is late or defective, and who's responsible when it is. It's what protects you when a supplier misses a season, ships the wrong product, or tries to change terms once you're dependent on them. For an e-commerce business, supply is everything, and a written agreement turns "they let me down" into an enforceable obligation with defined consequences. The time to set those terms is before you've built your store around a supplier, not after they've become a single point of failure.

3. A privacy policy and data terms

Selling online means collecting customer data — names, addresses, payment details, browsing behavior — and that comes with legal obligations you can't ignore. A clear privacy policy tells customers what you collect, how you use it, and how you protect it, and it's increasingly required rather than optional. Beyond compliance, it's part of the trust that makes people comfortable buying from you. Getting this right protects you from regulatory exposure and from the reputational damage of a data problem handled badly. Data is one of the areas where the rules are real and the penalties are real, so it deserves a proper document rather than a paragraph copied from another store that may not fit how your business actually operates.

4. Work-for-hire agreements for your site and content

Someone built your store, designed your brand, wrote your product descriptions, and shot your photography — and under copyright law, whoever created that work owns it by default. That means the developer or agency behind your site, and the freelancers behind your content, may legally own the assets your business runs on unless they signed the right agreement. A work-for-hire agreement — with a backup IP assignment and confidentiality — transfers that ownership to you before the work begins. For an e-commerce business whose brand and storefront are core assets, this is not optional. Skip it, and you can find yourself unable to modify your own site, or facing a claim from the very person you paid to build it. If this is new to you, read what is a work-for-hire agreement and when do you need one.

5. Contractor and service agreements for your team

Most e-commerce businesses run on a bench of contractors — ad buyers, VAs, fulfillment help, customer service, developers — and each of them is a relationship that needs terms. A solid contractor agreement defines scope, payment, confidentiality, ownership of anything they create, and how the engagement ends. It protects your systems, your customer data, and your processes from walking out the door, and it keeps a routine hiring from becoming a dispute over what was owed or who owns what. As you scale, the number of people touching your business grows, and each one is either governed by an agreement or a gap in your defenses. Standardizing these agreements is how you grow without accumulating risk.

Bottom line

An e-commerce business is a network of relationships — customers, suppliers, data, and the people who build and run your store — and each one holds up on paper or fails in a dispute. Purchase terms, a supplier agreement, a privacy policy, work-for-hire, and contractor agreements close the gaps most sellers leave open. The Contract Library has the agreements to lock down each relationship, every one built by a 20-year litigator and paired with training. Defense wins championships.

Frequently asked questions

What contracts does an online store need?

At minimum: website terms of service and purchase terms, a supplier or manufacturer agreement, a privacy policy, work-for-hire agreements for your site and content, and contractor agreements for your team.

Why does an e-commerce business need a supplier agreement?

Because your business depends on suppliers delivering on time, at quality, at the agreed price. A written agreement defines those terms and the consequences when a supplier fails, turning a letdown into an enforceable obligation.

Do I own my e-commerce website and product photos?

Only if the developers and freelancers who created them signed a work-for-hire agreement with an IP assignment. By default, the creators own their work, even after you've paid.

Does my store need a privacy policy?

Yes. Selling online means collecting customer data, which carries legal obligations. A clear privacy policy supports compliance and builds the trust customers need to buy.
