How Much Does It Cost to Build an E-commerce Website?

The honest answer to "how much does an e-commerce website cost?" is: anywhere from the price of a coffee per year to the price of a car, depending on how you build it. That range is not helpful on its own, so this article breaks the cost into its seven parts, shows how each one changes depending on whether you build from scratch or use an online e-commerce builder, and points out where the hidden costs usually sit. No made-up "average" figures — just the categories and what drives each one.

The Seven Cost Categories

Category	Building from scratch	Using an e-commerce builder
1. Platform	None (you own the code)	Subscription or yearly license — the main cost
2. Domain	Required	Optional; subdomain usually free
3. Hosting	Required, scaled to traffic	Included
4. Design / theme	Designer + front-end work	Included themes; premium themes optional
5. Payment processing	Gateway fees per sale	Gateway fees per sale; some platforms add their own fee
6. Development	The largest cost by far	Usually zero
7. Maintenance	Ongoing developer time, security, backups	Included

1. Platform

With a builder, the platform fee is what you pay for the software, hosting and updates bundled together. It is charged monthly or yearly, sometimes per plan tier. The two things to check: whether there is a per-sale commission on top, and whether the plan you can afford has product or order limits. A flat yearly fee with unlimited products is the simplest to budget.

Building from scratch has no platform fee — but every other category grows to compensate.

2. Domain

A domain name is a yearly cost from a registrar and is the same whichever route you take. It is optional on most builders because you start on a free subdomain (yourshop.platform.com). Many small stores run on the subdomain for their first year and add a domain later once the store has proven itself.

3. Hosting

A custom or self-hosted store (for example WordPress with WooCommerce) needs a server. Entry-level shared hosting is inexpensive but slow under load; anything reliable costs more, and someone has to manage it. With a hosted builder, this line is zero — hosting is part of the platform fee.

4. Design and Themes

Custom design means paying a designer and then a developer to implement the design. On a builder, the included themes cover most stores, and the design cost is your own time uploading a logo and banner. Premium themes exist on some platforms as a one-off purchase; they are rarely needed for a small catalog.

5. Payment Processing

This is the one cost you cannot design away if customers pay online: the gateway takes a percentage plus a small fixed amount per transaction, and it varies by country and gateway. Two things to watch:

• Platform transaction fees. Some builders charge their own percentage per sale on top of the gateway's fee, especially on lower plans. Over a year this can exceed the subscription itself.
• Cash on delivery. In markets where COD dominates, processing cost is effectively zero — the trade-off is handling cash and returns yourself.

6. Development

For a from-scratch store this is the dominant cost: catalog, cart, checkout, admin panel, security, and testing, all built by hand. It is measured in weeks or months of developer time. On a builder the development cost is normally zero, because the platform already has these pieces. It only reappears if you need a custom integration the builder does not offer.

7. Maintenance

Often forgotten at the planning stage. A custom store needs someone to apply security updates, fix bugs, maintain backups and keep it running when a dependency changes. Self-hosted plugin platforms need regular updates and occasionally break when plugins conflict. A hosted builder does this for you as part of the fee.

Three Realistic Scenarios

Scenario A: Low-cost hosted builder

Flat yearly license, free subdomain, included theme, cash on delivery or gateway-only fees. Your yearly cost is the license plus whatever the gateway takes on card orders. This is the cheap e-commerce website route and the right one for most first stores. Shop-E-Business is an example: 499 Tk/year in Bangladesh or 10 USD/year internationally, unlimited products, no commission, with the storefront on yourshop.shopebusiness.com. Details on the e-commerce builder page.

Scenario B: Mainstream platform with apps

Monthly subscription, a paid theme, three or four apps for reviews, delivery zones and invoices, a domain, and platform transaction fees. The yearly total is typically several times the headline monthly price. Reasonable when you use the ecosystem heavily; expensive when you do not.

Scenario C: Custom-developed store

Developer time for build, hosting, domain, design, gateway integration and ongoing maintenance. Right for businesses with genuinely unique requirements and volume that justifies the investment. Wrong for a first store.

Hidden Costs to Check Before You Commit

• Transaction fees charged by the platform in addition to the payment gateway.
• Plan limits on products, orders or staff accounts that force an upgrade.
• Apps for basics — if reviews, delivery zones or invoices need a paid add-on, add them to your total.
• Your own time — hours spent on hosting and plugin maintenance are a real cost even if no money changes hands.
• Migration — leaving a platform later means re-uploading products and photos. Choose carefully once.

How to Estimate Your Own Number

1. Decide the route: builder, self-hosted plugin platform, or custom.
2. List the seven categories and write a yearly figure for each, using the actual prices from the platforms you are considering.
3. Estimate monthly online-paid sales and apply the gateway (and any platform) percentage.
4. Add a domain if you want one now.
5. Compare the totals — and compare them against your expected monthly profit, not against each other.

Frequently Asked Questions

How much does it cost to build an e-commerce website?

From a few dollars per year on a low-cost hosted builder, to several hundred per year on mainstream platforms with apps, to thousands for custom development. The seven categories above are the full list.

What is the cheapest way to get an e-commerce website?

A hosted builder with flat yearly pricing, the included subdomain and theme, and cash on delivery or a gateway that only charges per transaction.

Are there hidden costs in e-commerce platforms?

Platform transaction fees, paid themes, paid apps for basic features and forced plan upgrades are the usual ones. Always compute the yearly total.

Is a more expensive platform better?

It is better for the business it was designed for. For a small catalog with a simple order flow, the extra features go unused and the cost is pure overhead.

Bottom Line

Most of the cost of an e-commerce website comes from development and maintenance — the two categories a hosted builder removes entirely. If your store does not need a custom checkout or unusual integrations, an e-commerce builder is almost always the affordable choice, and a flat-fee one like Shop-E-Business keeps the number predictable as you grow.
