Ecommerce development
Storefronts that stay fast at catalogue scale and survive a campaign.
What this actually is
Ecommerce development is mostly integration and performance. The storefront is the visible part; the work is catalogue, search, checkout, payments, tax, fulfilment and the half-dozen systems that have to agree about stock.
Two things decide whether a build succeeds: whether search and discovery actually help people find things, and whether the site stays fast when the catalogue is large and the campaign lands. Both are architectural, and neither is fixable with a theme.
What we do
Platform decision
Hosted, headless or custom — argued from catalogue size, integration surface and how unusual your commercial rules are.
Catalogue and search
Data model, faceting and ranking. Most discovery failures are search failures, and they show up as an exit rather than a complaint.
Checkout
The highest-value path on the site, built for the edge cases — partial stock, mixed tax, failed payment retry — rather than the demo path.
Integrations
ERP, warehouse, payments, tax, shipping and marketing, each with its own idea of what an order is.
Performance
Measured on real devices at real catalogue size, because both change the answer.
The stack
What it connects to
Integration surface is the honest driver of effort — ten systems is not ten times one system.
- ERP and inventory systems
- Warehouse and 3PL platforms
- Payment providers and wallets
- Tax engines — Avalara, TaxJar
- Carriers and shipping rate APIs
- Marketplaces and channel managers
- Email, CDP and marketing automation
How a project runs
Discovery
2–3 weeks
Catalogue shape, integration surface, and the commercial rules that are genuinely unusual.
Foundation
3–5 weeks
Catalogue, search and checkout working against real data.
Integration
4–8 weeks
ERP, fulfilment, payments and tax connected with the failure paths tested.
Launch
2–3 weeks
Load tested at campaign volume, with redirects mapped from the old site.
Where teams use it
Replatforming
Moving off a platform that has become the constraint, without losing the SEO built up on the old URLs.
B2B commerce
Account pricing, approval workflows and reordering, which generic platforms handle badly.
Large catalogues
Where search and faceting decide whether anything past the first page is ever seen.
Multi-market
Currency, tax, language and fulfilment differing by region.
Marketplace
Multi-vendor with onboarding, commission and payouts.
When this is the wrong answer
If Shopify with a good theme covers it, use Shopify. A custom build is justified by unusual commercial rules or integration depth, not by wanting control.
A replatform that loses your URLs loses your rankings. Redirect mapping is not a launch-week task; it is a project constraint from the first day.
Site speed is a conversion feature and it degrades as the catalogue grows. Testing at 200 products tells you nothing about 200,000.
Most discovery problems are search problems. A redesign that does not fix search moves the failure rather than removing it.
Frequently asked questions
Shopify, headless or custom?
Shopify where the commercial model is standard — it is cheaper and better supported. Headless where the storefront needs to be genuinely different. Custom where the rules are unusual enough that fighting a platform costs more than building.
Will we lose SEO in a replatform?
Not if redirects are mapped properly, and that is the single most common way replatforms go wrong. It is planned from the start rather than handled in launch week.
Can you integrate our ERP?
Yes, and it is normally the largest part of the work. Stock, pricing and order status each need a defined source of truth and a defined behaviour when systems disagree.
How do we handle a traffic spike?
Static rendering and CDN caching for the catalogue, load testing at the volume you actually expect, and a defined degraded mode so checkout survives even if something else does not.
Who owns the code?
You do, from the first commit — work happens in your repository under your licence, and the contract assigns IP outright. We keep no rights and build no dependency that makes leaving expensive.
What does it cost?
We do not publish a number, because the honest one depends on scope, integrations and the accuracy bar. Tell us the budget you are working with and we will say what it buys — or say plainly if it does not buy enough.
