E-commerce app costs in the UK

What a retail app costs against Shopify and marketplace fees, the three-year comparison, and when platform fees make a build the cheaper option.

The short answer

From £2,999 for a launched retail app on both platforms. Whether that is cheaper than what you pay now depends entirely on your volume and your fee structure, so compare over three years rather than against a monthly price.

The pattern: platforms are cheaper when you are small and get more expensive precisely as you succeed. A build is the opposite.

Common questions

How much does an ecommerce app cost in the UK?

From £2,999 for a launched app on both platforms with catalogue, cart, payment, and accounts. Agencies typically quote £20,000 to £60,000 for the same category of product.

Is it cheaper than Shopify over three years?

It depends entirely on your volume. Shopify is cheaper at low volume and its transaction and app costs scale with your sales. Run the three-year comparison on your own numbers rather than on a headline monthly price.

Do I need an app if I have a website?

Only if you have repeat customers. An app is a retention channel, not an acquisition one. For a business without regulars, spend the money on the website instead.
