The Contracts Every E-Commerce Business Needs (2026 Checklist)

An online store is a chain of promises: to the customer who buys, to the supplier who ships, to the processor who takes payment, and to the regulator who protects shoppers. Each link needs a contract, and a missing one usually shows up as a chargeback, a stockout, or a complaint. This page is a practical checklist of the contracts an e-commerce business actually needs, what each one does, and the common gap owners leave. Rules vary by country and state (the United States, United Kingdom, and India differ, especially on consumer rights), so treat this as general information, not legal advice, and adapt it to your market. ## Customer-facing contracts and policies These govern the sale itself and are the ones regulators look at. - Website Terms and Conditions (Terms of Sale). The contract formed when a customer places an order: how an order is accepted, price and taxes, delivery, risk and title, and liability. Common gap: no clear point at which the contract forms, so pricing errors cannot be corrected.

• Returns, Refunds, and Cancellation Policy. What a customer can send back, by when, and how refunds work. In many places consumers have statutory cancellation rights for online sales that you cannot remove. Common gap: a policy that is stricter than the law allows, which is unenforceable and invites complaints.
• Privacy Policy. The public notice of what personal data you collect and why, required almost everywhere you sell. Common gap: a generic template that does not match the trackers and tools actually running on the site.
• Cookie and tracking notice. Consent for analytics and advertising cookies, required in the UK and EU and increasingly elsewhere. Common gap: firing tracking cookies before consent is given.
• Acceptable Use and account terms. Rules for registered accounts, reviews, and user content. Common gap: no licence to use customer reviews and photos you later want to reuse in marketing. ## Supply and product contracts These keep stock flowing and define who is responsible when a product is faulty. - Supplier or wholesale purchase agreement. Terms with the businesses you buy stock from: price, lead times, minimum orders, quality, and returns of defective goods. Common gap: buying on purchase orders alone with no master terms, so faulty-goods liability is unclear.
• Manufacturing agreement. For own-brand products, covering specifications, tooling, quality control, and who owns the designs. Common gap: not securing ownership of designs and tooling, so you cannot switch manufacturers.
• Dropshipping agreement. If a third party ships directly to your customers, this sets who is responsible for stock accuracy, delivery times, and faults. Common gap: carrying the consumer-law liability for a supplier you do not control, with no indemnity.
• Product liability and compliance terms. Warranties and indemnities from suppliers for safety and labelling. Common gap: no indemnity, so a recall lands entirely on you. ## Fulfilment, payment, and logistics contracts - Fulfilment or 3PL agreement. Terms with the warehouse that stores and ships your stock, covering responsibility for loss, damage, and delays. Common gap: no clear liability for stock lost or damaged in the warehouse.
• Shipping and courier agreements. The carrier terms, including claims for lost or late parcels. Common gap: assuming the carrier covers full value when liability is usually capped.
• Payment processor and gateway terms. The agreement with the processor that handles card payments, including fees, chargebacks, and reserve rights. Common gap: not planning for chargeback liability and processor reserves on refunds.
• Marketplace seller agreements. If you also sell on a marketplace, its seller terms govern fees, payouts, and account suspension. Common gap: building a business on a marketplace account that can be suspended with no warning and no plan B. ## Data and marketing contracts - Data Processing Agreement (DPA). Back-to-back data terms with the vendors that process customer data for you, such as your platform, email, and analytics providers. Required under UK and EU GDPR and expected under India's Digital Personal Data Protection framework. Common gap: no DPA with a key processor, which is a compliance failure.
• Influencer and affiliate agreements. Terms with creators and affiliates who promote your products, covering disclosure of paid promotion, content rights, and payment. Common gap: no written disclosure requirement, which breaches advertising rules in many markets. ## People contracts - Employment agreements. For your own team, including confidentiality and, where relevant, assignment of any work they create. Common gap: no confidentiality terms for staff who see supplier pricing and customer lists.
• Contractor agreements. For designers, developers, and agencies, with clear IP assignment for the site and brand assets. Common gap: not owning the website or logo you paid a freelancer to make. ## A simple way to prioritise If you are starting out, the order that protects you most is usually: terms of sale with a clear order-acceptance point, a returns policy that matches the law, a privacy policy and cookie notice that match your site, a DPA with your main data vendors, and clear supplier terms for faulty goods. Add fulfilment, payment, and marketplace terms as those parts of the business grow. Keep one current version of each, because an outdated returns policy on a live site is a real liability. ## Keeping all of this in one place The hard part is rarely writing one policy. It is that the supplier agreement is in email, the 3PL terms are in a drawer, the DPA is in a shared drive, and nobody knows which returns policy is live or when the supplier contract renews. Drafting, review, e-signing and e-stamping, tracking, and governance of all these contracts can live in one AI workspace tuned to your company and built on Claude, with public per-seat pricing and a 7-day free trial. Adira is India-first while aiming to be global-capable, so jurisdiction depth varies by region and is worth confirming during the trial, and the single-pane Command Centre that shows what renews and what is at risk is on the roadmap. See how it works. The checklist above stands on its own whatever you use to manage it. ## Bottom line An e-commerce business needs customer contracts and policies (terms of sale, returns, privacy, cookies), supply and product contracts (supplier, manufacturing, dropshipping, product liability), fulfilment and payment contracts (3PL, shipping, payment processor, marketplace terms), data and marketing contracts (DPA, influencer and affiliate terms), and people contracts (employment and contractor agreements with IP assignment). Start with terms of sale, a lawful returns policy, privacy and cookie notices, a DPA, and clear supplier liability. Consumer rights and data rules vary by jurisdiction, so adapt each document to where you sell and have a lawyer check the ones that carry real risk.
