Describe the catalog and audience
Explain what you sell, who buys it and how people choose between products. Include the number of initial products and any meaningful variation in their content. If some photography or copy is unfinished, say so. The team can then plan placeholders without mistaking them for approved launch content.
List the important journeys
Describe the pages and actions customers need. A store might include collection browsing, product comparison, subscriptions or a wholesale inquiry flow. Do not assume a short phrase such as standard e-commerce captures every requirement. Clarify which journeys are essential for the first release and which can come later.
Agree on design review points
Review the homepage and a representative product page before building the full store. Include mobile layouts and the main typography and color decisions. This catches disagreements while the work is still focused. After approval, new directions should be discussed as scope changes rather than hidden inside routine revisions.
Make ownership and costs explicit
Specify who supplies the theme, domain, product content and required app accounts. Ask for additional or recurring costs to be identified before installation. Define the handoff and the launch checklist. A clear brief does not remove every unknown, but it makes the project’s assumptions visible before they become expensive surprises.

Build a simple page-and-function map
For every required page, write its purpose, primary content and main action. A collection page helps shoppers narrow options; a product page helps them decide; an FAQ answers recurring concerns. Then list functions that affect several pages, such as account access or a particular catalog rule. This keeps the brief from becoming a mixture of page names, visual preferences and technical features with no clear relationship between them.
Separate approved content from placeholders
Label product photography, reviews, claims and descriptions according to their status. A placeholder helps the design continue, but it should not be mistaken for publishable content. Assign an owner to replace each unfinished item and define the final review point. In particular, do not use invented reviews or unsupported product claims to make the demo look complete. The layout can demonstrate where verified material will appear without pretending that material already exists.
Agree on the release checklist
Describe what the team will verify before launch, including the shopping journey, navigation, required content and agreed integrations. Confirm who makes the final go-live decision and who owns the store accounts. Use a written list so both sides know what remains. Avoid treating the last visual review as proof that every operational setting has been checked; storefront appearance and store readiness are different parts of the handoff.
Keep changes reviewable
When a new request appears, compare it with the agreed scope and explain its effect before implementing it. A small content edit and a new shopping workflow are not the same kind of change. Record approved adjustments in a place both sides can access. Clear change handling protects the relationship because the client can make an informed choice about priorities instead of discovering extra work or a delayed timeline at the end.
