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.

How much does an e-commerce website cost?

A functioning online store with real checkout starts from about $150 hiring direct and runs to $10,000 or more through an agency. What moves the number most is not product count — it is how far your catalogue sits from a standard product grid.

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 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.

The seven days

Day 1 — catalogue model written down and signed off, with a confirmed price
Days 2–3 — front end on a staging URL: category, product, cart, checkout
Days 4–5 — payments, tax and shipping rules, webhook fulfilment, order emails
Day 6 — QA: real card, real phone, mobile data, declines, out of stock, keyboard
Day 7 — launch, SSL, redirects, Search Console, sitemap submitted

What genuinely adds time

A catalogue that does not fit a product grid — configurable plans, made-to-measure formulas
Integrations with accounting, dispatch or an ERP
Migration from an existing store, which needs a full redirect map
Product data entry at volume, which is real time somebody has to spend

The stage nobody should skip

Day one. Choosing a platform before writing down what a product is, and what varies, is the single most expensive mistake available in an e-commerce project — and it is paid for in week four, not week one.

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.
