How long does an e-commerce site take to build?

About seven days from signed scope for a standard catalogue store, provided your product content exists on day one. Larger catalogues, custom pricing logic or third-party integrations add time — and a supplier should tell you that before you commit rather than in week two.

How do I write a website brief?

Answer four things: what the site must do, who produces the content, what it must integrate with, and when it has to launch. Every scope dispute I have seen traces back to one of those being left implicit, and a clear brief also makes quotes comparable.

What do you need from me to start a website project?

One person who can make decisions within a day, your content or a decision to reuse what exists, photographs of real work, and access to your domain and hosting in your own name. The first item matters more than all the others combined on a short build.

Process

How long does a website take to build?

A small business website takes about three days of build time once scope is agreed and content exists. An e-commerce store takes about a week, a custom application about ten days. What stretches those timelines is almost never the code — it is decisions and missing content.

Where the time actually goes

Phase	Business site	Store
Scope agreed in writing	Day 1	Day 1
Build on a staging URL	Day 2	Days 2–3
Payments and integrations	—	Days 4–5
QA on real devices	Day 3	Day 6
Launch and indexation	Day 3	Day 7

The two things that move the date

Decision latency — on a three-day build, a decision that waits a day costs a third of the project
Content readiness. The build finishes and the site has eleven products because nobody was assigned the other three hundred

What a short timeline does not mean

It does not mean a template. It means the sequence is fixed rather than improvised. What should worry you in a quote is not a short timeline — it is a quote given before anyone asked what your catalogue looks like.

The longer version

This answer is deliberately short. If you want the full treatment, E-commerce website development: what the whole build actually involves covers it in about 7 minutes — free, ungated, written from client work.
