Starting to sell online, or scaling up, you reach the same question: a ready platform like Shopify, or a store built just for you?

Either can be right. What is wrong is deciding on launch cost alone.

When a ready platform is strong

Ready platforms come with payments, shipping, invoicing integrations, product management and themes. You can be selling within weeks, and security and updates are the provider's job.

They are usually the right choice when:

• You are new and still testing product-market fit.
• Your product structure is standard: variants, cart, checkout, shipping.
• Your team is small and cannot spare resources for technical upkeep.
• Most sales already come from marketplaces and the site is a supporting channel.

The hidden costs of ready platforms

• App and plugin fees: every feature on top of the base plan, such as advanced filters, loyalty or B2B pricing, adds another monthly charge.
• Transaction fees: some platforms take a cut per sale, or charge extra if you do not use their payment system.
• The mould: if your sales model does not fit the platform's logic, you bend your processes to the software.
• Sameness: among thousands of stores using the same themes, brand experience struggles to stand apart.

A ready platform sells you a fast start. A custom build sells you the ability to grow on your own rules. Which you need depends on where you stand.

Signals that favour custom

• Complex pricing: dealer, wholesale and retail tiers, customer-specific discounts, volume pricing.
• Unusual product structure: made to measure, personalisation, configurators, rental or subscription.
• Deep integration: a store that must talk in real time with ERP, production planning, warehouse or accounting.
• Brand experience: a site that is itself part of the brand, telling a story and inviting interaction.
• Scale: monthly fees and commissions together now exceed what a custom system would cost to maintain.

The risks of custom

Custom means longer development, higher upfront cost and responsibility for maintenance. There is also dependency risk: if the code, server access and documentation are not yours, changing partners can lock your store. Settle this in the contract. We covered similar traps in agency contracts separately.

A simple test

In the last six months, how many times did you say "I wish our site could do this" about something the platform could not solve? If never, stay on the platform and spend on marketing. If several times, and they affect sales directly, compare a custom build on three-year total cost. What an admin panel should include is in our admin panel guide, and the cost items are in our build-cost breakdown.

Frequently asked questions

Will I lose SEO moving from a platform to a custom build?

Not if it is planned. Old URLs need permanent (301) redirects to their new equivalents, titles and descriptions should be kept, structured data carried over, and Search Console watched closely after launch. Most ranking losses come from forgotten redirects.

What is headless e-commerce, and do I need it?

Headless separates the storefront from the commerce engine behind it. It gives full design freedom and multichannel flexibility but raises development and maintenance cost. Consider it if brand experience is a priority and you have a technical team or partner; most small stores do not need it.

If I sell on marketplaces, do I need my own site?

Marketplaces bring traffic, but they keep most of the customer relationship, data and pricing control. Your own site lets you build a direct relationship with repeat buyers and sell without commission. For many brands the right model is marketplaces to win customers, their own site to keep them.

We build custom e-commerce sites with their own admin panel, designed around how you sell. Details are on our web and e-commerce page.
