How can our agency deliver websites and apps through a partner?
Agree on the delivery model, named responsibilities, client communication, scope and approvals before quoting. Use a shared brief, an early feasibility review and clear acceptance tasks. Define confidentiality, ownership, support and handover in the appropriate agreement, then test the partnership on a manageable project.
The key idea
A partner should extend what your agency can deliver while making responsibility clearer for the client. A hidden chain of assumptions creates more work for everyone.
Choose a delivery model you can explain
Decide whether the agency is the main delivery contact, the client contracts separately with the developer, or the teams present a joint scope. Agree how the relationship is described and what the client needs to know. Do not invent credentials or claim your agency performed specialist work that another team actually delivered.
An illustrative design agency might own research, branding and page copy while a partner owns application implementation and release preparation. Name the boundaries and the person who resolves a gap. The client should know where to send a question without being forced to manage the supplier relationship themselves.
Check feasibility before the proposal becomes a promise
Bring the proposed user journey, integrations, languages and launch constraints to the technical team early. A campaign concept may require a payment account, catalogue data or a staff system the client does not yet have. Identify these dependencies before putting a fixed launch promise in a sales presentation.
Use a prototype or focused discovery where uncertainty is substantial. Record what is included, what must come from the client, and what needs confirmation by another provider. Keep optional features separate so a change in scope does not appear later as a surprising extra bill.
In practice · illustrative example
Hand over the design's behaviour, not only its appearance
An agency prepares a campaign page with a prominent enquiry form. The development partner needs to know which fields are required, where the enquiry goes and what the confirmation means. Include mobile layouts, error wording and the intended staff response in the handover. Otherwise, a visually faithful implementation can still behave differently from the offer the agency sold.
Keep one consolidated feedback route for the client, agency and developer. Decide who resolves conflicting edits and who can approve a change to the customer promise. Review a complete test enquiry together before launch. This makes the partnership a clear delivery chain rather than a sequence of isolated screenshots.
The campaign handover includes behaviour
-
Approve the offer
The client and agency agree what the customer is being promised.
-
Specify the journey
Design files include form states, mobile behaviour and response wording.
-
Implement and test
The developer demonstrates the complete enquiry and its exception path.
-
Accept together
The responsible teams check the page and receiving operation together.
Make the design handoff about behaviour
A set of attractive screens does not explain loading, errors, long Arabic names or unavailable appointments. Include the important states and the content that appears in them. For an example booking project, show how the customer chooses, changes and cancels, and what the staff member sees afterward.
W3C’s guidance on form notifications is useful context for clear feedback. Review the wording and behaviour with both teams rather than assuming the developer will invent them from a visual layout. Agree how approved design changes are recorded, and avoid sending different instructions through separate chat threads.
Keep feedback and approvals in one place
Name the client decision maker and the agency contact responsible for collecting feedback. Ask for consolidated decisions at agreed stages. Conflicting messages from several people can cause the technical team to rebuild the same feature while everyone believes they approved something different.
Use a simple decision record: issue, proposed option, impact and approval. When a request changes scope, explain the consequence before implementing it. A partner meeting should end with a clear owner and next step, not only a friendly discussion of possibilities.
Make the post-launch arrangement part of the offer
Decide who receives defects, who handles customer support, and who estimates new work. Distinguish content changes from technical maintenance and third-party outages. Agree response coverage that the teams can actually support, with costs and exclusions visible in the client-facing scope.
Define the agreed account ownership, documentation, repositories where contracted, and handover assistance. Protect confidential client information and share it only with authorised participants. Have the appropriate advisers review commercial and confidentiality wording. Start with one manageable engagement and review whether the handoffs work before expanding the partnership.
A worksheet for your team
A handover sheet for agency projects
Attach this to the approved design so the developer can implement the intended experience.
| Decision | Evidence to request | What to do next |
|---|---|---|
| Form behaviour | Required fields, errors, destination and confirmation. | Resolve missing states before estimating implementation. |
| Approval route | One contact who consolidates client feedback. | Keep conflicting instructions out of the delivery queue. |
| Launch responsibility | A completed test enquiry and named receiving staff. | Agree who maintains the page after launch. |
A shared test is often the quickest way to expose a misunderstanding. Run it while copy, design and implementation can still be corrected together.
A partnership brief to prepare together
- Delivery model and honest client-facing description.
- Agency, developer and client responsibilities.
- Feasibility review and dependencies before promises.
- Design states, content and acceptance scenarios.
- One feedback and change-approval record.
- Confidentiality, ownership, support and handover arrangements.
Frequently asked questions
Can the development work be delivered under our agency brand?
Agree the permitted presentation, contracting roles and intellectual-property arrangements. Keep factual claims accurate, including who performed specialist work. The client-facing responsibilities should remain clear.
Should the technical partner join client discovery?
Include technical expertise where integrations, unusual workflows or delivery constraints need clarification. Agree who leads the meeting and records decisions so the client gets one coherent process.
Who should own the support relationship?
Choose the arrangement the teams can operate and explain it in the scope. Separate the client contact from the technical escalation route, and test the handoff before launch.
