A website development company checklist should help you verify the proposed work before paying for it. Ask for relevant evidence, a written scope, an editing demonstration, clear account ownership and measurable acceptance criteria. A portfolio alone cannot confirm how your own project will be delivered.
Use the same brief with each shortlisted supplier. Otherwise, one quote may cover five prepared pages while another includes content planning, integrations and migration. The prices will look comparable even though the work is different.
Write a brief that a supplier can estimate
State what the website must help visitors do. Examples include requesting a quotation, booking an appointment or accessing an account. Identify the main audiences, required pages, languages and integrations. Mark each requirement as essential for launch or suitable for a later phase.
Also list the materials you will supply. Copy, photographs, product data and approvals can affect delivery. A useful proposal explains what happens when an input arrives late or changes after approval.
Ask for evidence you can assess
Request a demonstration of a relevant workflow, not just a collection of homepages. For an enquiry website, inspect a service page, a mobile menu and the enquiry journey. For a portal, ask to see appropriate account permissions and error handling using demonstration data.
Respect confidentiality. A supplier should not expose another client’s private customer records to prove experience. A sanitised demonstration, an authorised reference or a public project explanation can provide evidence without disclosing protected information.
Website development company checklist
| Ask for | What a useful answer contains |
|---|---|
| Scope | Page types, features, integrations, content responsibilities and exclusions. |
| Acceptance | Specific tasks that must work and who will sign them off. |
| Ownership | Control of the domain, hosting, CMS, repository and relevant licences. |
| Change process | How a new requirement affects the price and schedule before work begins. |
| Handover | Training, documentation, backups and access transfer. |
| Support | Included defect fixes, response arrangements and separately charged work. |
Turn broad promises into acceptance checks
“Mobile friendly” is too broad on its own. Specify which page types and actions will be checked on representative screen sizes. “SEO included” also needs detail: page metadata, redirects, indexing settings and content work are different responsibilities.
Accessibility deserves a practical check. Ask whether the proposed journey works with a keyboard, has meaningful form labels and presents readable content. The W3C accessibility easy checks provide a useful starting point; a quick check is not a complete accessibility audit.
For forms, agree on a controlled test that confirms both submission and delivery to the intended system. A success message on the page does not prove that the sales team received the enquiry.
Resolve access and recurring costs early
Document who will hold each business account and who can recover it. Ask which paid tools are billed to your company and which are covered through the supplier. Establish what happens if you change suppliers or stop a maintenance arrangement.
Review renewals and third-party charges alongside the build fee. The website cost and quotation guide explains why a low headline price can leave important costs outside the comparison.
Use the proposal to make the decision
Score the evidence against your requirements. A supplier may be excellent at brochure websites but unsuitable for a complex internal application. Another may have strong engineering skills but need a separate content partner. Fit matters more than a broad claim to do everything.
Before signing, resolve assumptions in writing. Link payments to agreed deliverables and acceptance steps. Have the commercial terms reviewed appropriately for your business; this checklist does not replace a contract review.
Common questions
Should I choose the lowest quotation?
Compare equivalent scope first. Then weigh ownership, support, relevant evidence and the cost of omitted work alongside the price.
Is a high SEO score enough to approve delivery?
No. It does not confirm form delivery, accurate content, accessibility, reliable integrations or future search performance.
What if the supplier cannot show private client work?
Ask for public examples or a sanitised demonstration. Respecting client confidentiality is compatible with providing relevant evidence.
