1. Define the decision the website must support
A useful website proposal begins with a clear business situation. A professional services company may need prospects to understand its offer and request a conversation. A product business may need visitors to compare variants and complete a purchase. Describe the customer, their questions and the action you want to support. These details help an agency estimate the work behind the interface.
Include the current website, the reason for the project and the constraints that shape a decision. A launch date, an existing sales process or a small internal content team can change the appropriate scope. Identify which needs are essential for launch and which can follow later. This gives every supplier the same starting point and makes their assumptions easier to compare.
2. Turn the page list into a content inventory
A list that says home, services and contact leaves important questions open. Specify how many services need their own page, whether the team maintains project examples and whether each language needs complete content. Mark what already exists, what needs rewriting and who can approve it. Content preparation belongs in the project plan because design and development depend on it.
Describe representative examples rather than sending an unfiltered archive. One typical service page, a product with several options and a real enquiry scenario reveal more than a folder of disconnected references. Where materials contain personal or confidential information, prepare a suitable demonstration. Label examples clearly so a supplier can distinguish a requirement from a visual reference.
3. Use a scope matrix to expose assumptions
The following is an illustrative procurement framework. Add an owner and acceptance condition to each line; it becomes a shared document for comparing proposals and checking delivery.
- Pages and templates: name each content type and the examples included at launch.
- Content and languages: state who writes, translates, uploads and approves each version.
- Integrations: identify the systems involved, available access and the person who owns them.
- Handover: specify editing guidance, account access, documentation and the support period requested.
4. Agree acceptance before approving the design
Visual approval should sit alongside practical checks. Can a visitor use the mobile menu, understand a service and submit the intended form? Can an editor update a page without breaking its structure? Include the devices, key journeys and error states that matter to the business. Make the acceptance process understandable to the person who will sign off the work.
For forms, W3C guidance on accessible forms explains the value of clear labels, instructions and feedback. Ask the proposal to include those behaviours. A mockup of a successful submission alone does not describe incomplete fields, errors or the confirmation a visitor receives after sending an enquiry.
5. Include performance and measurement responsibilities
Agree how the team will examine loading, interaction and layout stability. Google describes Core Web Vitals as measures of those aspects of real user experience. Define an appropriate verification approach and the relevant page types. Avoid treating a single laboratory score as a guarantee of commercial performance or a permanent result across every device.
Measurement also needs an owner. List the actions that need checking, the tools already in use and the access needed for testing. Separate a click on a contact button from a successfully submitted enquiry. If a booking or sale happens in another system, identify that dependency before assuming the website can report the final outcome.
6. Compare exclusions and change handling
When proposals arrive, compare what is included, excluded and assumed. A lower estimate may reflect fewer templates, client-supplied copy or a different support arrangement. Ask how revisions are handled, what triggers a scope change and who can authorise it. Recording these rules helps both parties respond when the business learns something new during the project.
Platform selection is one of those decisions, but the brief should make its implications visible. Our existing guide to choosing a website platform provides related reading. Confirm the proposed editing experience, maintenance responsibilities and integration limits against your actual requirements before accepting a recommendation.
7. Send a brief that can start a useful conversation
You do not need to solve the entire project before speaking to an agency. Bring the commercial objective, a representative page inventory, your existing systems and the decisions that remain open. A good discovery conversation should reduce uncertainty and turn those inputs into a scope the business can review.
Explore WIDECREATION’s website and digital marketing services, then share your website brief with the current URL, priority audience, required languages and intended launch. Include any fixed constraints so the proposed next step addresses the project you actually need.
