One-sentence conclusion Β· TL;DR

Website delivery is divided into five milestones: requirements confirmation, design, development, testing, and launch, with a typical cycle of 4–6 weeks. Acceptance criteria are complete pages, functioning features, meeting performance standards, and completed basic SEO configuration. The timeline is affected by how quickly materials are provided, so both parties need to clarify time responsibilities.

Common Questions
What causes project delays?

The most common reasons are delayed provision of materials and repeatedly changing requirements. Next is repeated revisions to design drafts. It’s recommended to communicate thoroughly and clarify requirements during the requirement confirmation stage to reduce later rework and delays.

What if it fails acceptance?

Provide feedback item by item against the acceptance criteria, and the service provider will make revisions. We recommend consolidating feedback during the acceptance phase to avoid fragmented back-and-forth changes. Clear acceptance criteria are the foundation for efficiently resolving disagreements.

Can it still be changed after launch?

Yes. Minor post-launch tweaks (text edits, image swaps, etc.) are usually covered by after-sales service; larger changes (page redesigns, new features) may require separate evaluation. The exact boundaries should be spelled out in the contract.
