Make the scope concrete before comparing estimates.
Give each prospective partner the same brief: the user, the required outcome, existing systems, and the conditions for acceptance. Ask which assumptions sit behind the estimate and which unknowns need investigation. A quote is difficult to compare when one includes migration and deployment while another covers only development.
Separate required deliverables from possible additions. Ask how review rounds, corrections, and requests for new behaviour are distinguished. The answer should make it clear how a change is assessed and approved.
Agree who speaks to the client.
Decide whether your agency handles all communication or invites the development partner to selected technical conversations. Name the person who can approve changes, answer product questions, and make delivery commitments.
Discuss branding and confidentiality explicitly. A useful arrangement records how the partner is introduced, what they can access, and whether work may be referenced publicly. Avoid leaving client expectations to an informal understanding.
Ask to review working delivery.
Ask how you will see progress and give feedback. A checkpoint should show the relevant user journey or technical behaviour, with known limitations visible. Screenshots can support a review, but they do not establish that permissions, integrations, or failure paths work.
Agree acceptance examples early. For a workflow, include a duplicate trigger and missing data. For an application, include the roles and actions that matter. A labelled demonstration can help you inspect an approach, but it is not evidence of a past client outcome.
Clarify ownership, licences, and access.
The agreement should define rights to the deliverables and identify third-party services, libraries, and licence constraints. Ask who controls the repository, hosting, domain, deployment credentials, and paid service accounts. Confirm what the client will receive and when.
Use only the access needed for the work and agree how it is removed at the end. Plan a secure process for credentials rather than including them in a project brief.
Plan the handover before launch.
Request a proposed handover list: setup instructions, configuration references, deployment notes, known limitations, and recovery procedures where relevant. Decide who will receive reports after launch and who will triage them.
Support needs a stated scope. Confirm any included period or coverage in writing, how new features are estimated, and who remains responsible for hosting, updates, and provider costs.
Start with a project you can evaluate.
Choose a bounded piece of work with a named reviewer and a clear definition of done. It should be meaningful enough to reveal how communication and delivery work together. Keep your client commitments aligned with the scope and dependencies that both teams have agreed.
A comparison sheet for your first conversation
- Scope: record what is included, excluded and still unknown.
- Review: name the approver and the journey they will test.
- Communication: agree who speaks to the client and approves changes.
- Ownership: list the code, accounts, documentation and rights to be handed over.
- Support: identify the reporting contact, coverage and ongoing costs.
Use the same headings for each potential partner. Follow up on unanswered items before comparing headline prices.
