Ecommerce Development UK: Online Shops That Run the Back Office Too

Ecommerce is a back-office problem as much as a front-end one

The shop window matters, but the money is usually lost behind it: orders retyped into accounts, stock levels that drift, refunds that never make it to the ledger. Our ecommerce work started there. Around 2011 we built a full KashFlow and OpenCart integration that created customers automatically, raised invoices when payment cleared, synced stock and prices, and issued credit notes for cancelled orders. We later ported it to Magento.

That is still how we approach a shop. We design the storefront with you, but we spend just as much time on what happens after the customer clicks pay: where the order goes, who needs to know, and what can be automated so your team handles exceptions instead of routine.

Choosing a platform

We also maintain CubeCart stores, which is where our own ecommerce work began.

Integrations that remove manual work

• Accounting: orders, customers, payments and refunds pushed to Xero, QuickBooks Online, Sage or KashFlow through their APIs. See accounting software integration.
• Stock and ERP: two-way sync of stock levels, prices and order status with your warehouse or ERP, with a log of every change. See ecommerce ERP integration.
• Marketplaces: listings and orders from Amazon, eBay or others brought into one place.
• Couriers: labels and tracking numbers created from the order, tracking sent to the customer.
• Payments: Stripe Payment Intents with webhooks, so an order is only released once the payment is confirmed, including after 3D Secure checks.

We build these with queues, retries and idempotency keys, because APIs go down and webhooks arrive twice. A sync that silently fails is worse than no sync at all.

Product data, feeds and catalogues

Loading products is often the hidden cost of running a shop. We have built bulk product loaders and stock feeds since our OpenCart days, and the same patterns apply on any platform:

• Importers that read supplier CSV, XML or API feeds, map their fields to yours and flag anything that does not fit.
• Scheduled price and stock updates with rules, such as minimum margin or rounding.
• Image handling that resizes, renames and serves modern formats.
• Google Merchant Center and marketplace feeds generated from your catalogue.

The aim is that adding a range of five hundred products is a supervised import, not a week of copy and paste.

The storefront: speed, checkout and trust

Once the back office is sorted, the storefront has one job: get the right customer to a completed order with as little friction as possible. In practice that means:

• Fast category and product pages, with images served in modern formats at the right size for the device.
• A checkout with as few steps as the platform allows, guest checkout where it suits you, and UK postcode lookup to cut address errors.
• Clear delivery costs and dates before the basket, not as a surprise at the last step.
• Product structured data so search engines can show price and availability.
• Analytics events on each checkout step so you can see exactly where people drop out.

Migrations without losing what works

Moving platform is risky mainly because of what gets left behind: URLs, customer passwords, order history and reviews. We have built migration tools before, including CubeCart to OpenCart and osCommerce to CubeCart, and we migrate shops in a way that keeps URL structures where possible and redirects everything else. Customers, orders and products move across with checks that the counts match. See ecommerce migration for detail.

Whichever route you take, it starts with a free chat and ends with a fixed-price quote for a defined scope. If you want the shop hosted and looked after afterwards, we can arrange that through our sister companies. Talk to us.

• A new shop or a rebuild on the platform that suits your catalogue and team
• Custom extensions, apps or modules for features the platform lacks

• Platform migration with URL mapping, 301 redirects and data transfer
• Checkout improvements, UK postcode lookup and payment gateway integration

How it works and what it costs

Every project gets a fixed-price quote after a free initial chat and a short scoping stage. You own the code and the data.

1. Free chat

   Tell us the problem in plain English: what you do now, what goes wrong and what "better" looks like. No charge, no obligation.

2. Scoping

   We map the processes, systems and data involved, agree what is in and out, and write it down so there are no surprises.

3. Fixed-price quote

   You get a fixed price for the agreed scope, or a phased plan for bigger builds, so you can start small and prove it works.

4. Build and test

   We build in short stages you can see and try, test against real data, then go live carefully with a rollback plan.

5. Hand over and look after

   You own the code and the data. We can host it, support it and keep improving it, or hand it to your own team.
