E-Commerce Contract Negotiation

Before signing an ecommerce website development agreement, make sure you and the developer can describe the same store, launch process, and support plan. Ask each bidder to respond to the same brief so you can compare what the price covers.

Define what the store needs at launch

List the essentials, such as product variants, payment methods, shipping rules, and order notifications. If you are replacing an existing store, specify which products, customer records, orders, and URLs need to move. Put optional integrations and automation in a separate phase so you can price them independently.

Compare proposals using the same checklist

Ask each developer to break out design, development, data migration, testing, training, and post-launch support. Identify recurring charges for hosting, subscriptions, and extensions. Confirm who supplies product information and photography, and who sets up accounts with the payment processor and shipping provider.

Agree on milestones and acceptance tests

Tie milestones to work you can review, such as an approved prototype or a test store ready for checkout testing. Agree on how changes affect pricing and timing. Before launch, place a test order on a phone and a desktop, check confirmation emails and shipping charges, and test a refund and any inventory updates. Assign someone to sign off and decide who can pause or reverse the launch if a critical issue appears.

Plan access, handoff, and ongoing support

Agree on who controls the domain, hosting, store administrator account, and third-party subscriptions. Ask for a handoff that covers backups, updating products, and handling orders. Clarify how to report a checkout outage, what support covers after launch, and what work costs extra.

Keep performance goals measurable

If a proposal links fees to sales or traffic, agree on the baseline, data source, and measurement period. Promotions, inventory availability, and ad spending can affect results independently of the website. Use launch acceptance tests to measure the work the developer directly controls.
