Custom E-Commerce Website Design in South Wales
Proper Banging Web Design builds custom online shops for businesses in Newport, Cardiff, Swansea and across South Wales. Every shop is hand-coded on Google Firebase with Stripe Checkout for payments and Xero for automatic invoicing. You pay once, from £3,500, and own the lot — no Shopify subscription, no transaction cut on top of Stripe, and £0 a month in platform fees.
- → A custom e-commerce site from PBWD starts at £3,500 as a one-off — standard shop with Stripe, Xero, product management and an admin dashboard.
- → You pay no Shopify subscription and no transaction cut on top of Stripe (Stripe is 1.4% + 20p per UK card sale, and that's it).
- → You own the shop outright — code, data and customer list. Stop paying and nothing disappears.
- → Hosting runs under £10/month on Firebase — the rented-platform fees are gone for good.
- → Already on Shopify, Wix or Woo? We migrate it across — products, orders and rankings included.

Us vs Shopify & WooCommerce.
A custom Firebase shop has no monthly platform fee; Shopify starts at £69/mo before you sell a thing — and takes a cut on top of Stripe. Here's what you're actually paying for with rented platform e-commerce.
| Shopify / Woo | Us | |
|---|---|---|
| Monthly Fee | £69-£384/mo | £0 |
| Transaction Fee | 0.5-2% extra | Stripe only (1.4%+20p) |
| Ownership | You rent it | You own it |
| Invoicing | Paid app | Xero (automatic) |
| Load Speed | 2-5 seconds | <1 second |
| SEO | Basic / paid apps | Full, built in |
| Maintenance | Plugin updates | Zero |
| Custom Design | Theme limitations | Completely bespoke |
How much does an e-commerce website cost?
A custom e-commerce website in the UK starts from £3,500 as a one-off. What pushes the price up is catalogue size, integrations and bespoke features — not a monthly subscription. Here's roughly how it tiers. Every quote is fixed up front, so you know the number before we start.
Up to ~50 products, Stripe Checkout, Xero invoicing, product & stock management, order tracking, customer accounts, voucher codes and a full admin dashboard. The sweet spot for most South Wales shops.
Hundreds of products, complex variants, subscriptions or recurring billing, bespoke filtering and search, advanced reporting, or integrations with your stock system or ERP. More moving parts, priced fairly.
Multi-vendor marketplaces with seller dashboards, commission tracking, product approval workflows and separate seller logins. Built bespoke from scratch — tell us what you need and we'll scope it.
Whatever the tier, it's a one-off. There's no platform subscription bolted on top, no per-sale cut beyond Stripe's standard 1.4% + 20p, and hosting on our Firebase platform sits under £10 a month. We don't do the Newport, Cardiff or Swansea web design "starts from £29/mo forever" trick — you pay once and you own it.
Is a custom shop cheaper than Shopify?
Over time, yes. Shopify feels cheap on day one because you only see the monthly figure. But you're renting your shop — and rent never stops. A custom build is a one-off: pay once, own it forever, pay £0/month in platform fees after. Here's the same shop, three years deep.
| Shopify (rented) | Custom PBWD (owned) | |
|---|---|---|
| Up-front build | £0–£500 theme | From £3,500 one-off |
| Platform fee / year | £828–£4,600+ | £0 (hosting <£120/yr) |
| Extra cut per sale | 0.5–2% on top of Stripe | £0 — Stripe only |
| Paid apps (typical) | £240–£1,200/yr | £0 — built in |
| 3-year platform cost | ~£2,500–£15,000+ | £3,500 + ~£360 hosting |
| After year 3 | Keeps charging, forever | ~£10/mo hosting, done |
The crossover point lands somewhere between 18 and 36 months depending on your Shopify plan and sales volume — after that, a custom shop saves you money every single year, and the gap only widens. On a busy shop turning over six figures, Shopify's percentage cut alone can dwarf the one-off cost of building properly. That's the whole reason we push Firebase over rented platforms: own the asset, kill the rent.
Your shop. Your data. Full stop.
You own everything
When we hand over a custom shop, it's yours — the code, the design, the customer list and every order. It's your Firebase project, your Stripe account and your Xero account, all in your name. Stop paying us and nothing switches off. That's the opposite of Shopify or Wix, where the shop you "built" vanishes the day you cancel the subscription. You're not locked to PBWD either: the code is standard and any competent developer can pick it up.
Migrating off Shopify, Wix or Woo
Already trapped in a rented platform? We get you out. We migrate your products, images, prices, customer accounts and order history across to a custom Firebase build, set up redirects so the rankings you've earned carry over, rebuild the design properly, and wire up your Stripe and Xero. You walk away from the monthly fees with your data intact. We run this exact stack on our own sites and ten South Wales city pages, so we're not guessing — we live in it daily.
Every shop also ships with full SEO built in — clean schema, fast loads and proper product pages — because a shop nobody can find isn't selling anything. Want to talk it through? Give us a shout and we'll scope your shop and quote a fixed price. We also build for businesses up the road in Bristol and across the M4 corridor.
Questions About E-Commerce.
How much does an e-commerce website cost in the UK?
A custom e-commerce website in the UK starts from £3,500 as a one-off with Proper Banging Web Design. That standard tier covers Stripe payments (Card, Apple Pay, Google Pay), Xero invoicing, product management, shopping cart, order tracking, customer accounts and an admin dashboard. Larger product catalogues, custom integrations and multi-vendor marketplaces run higher — typically £5,000 to £8,000+. There is no monthly platform fee like Shopify, so the price you pay is the price you pay.
What makes one e-commerce website cost more than another?
Three things drive the price: catalogue size and complexity, integrations, and bespoke features. A 50-product shop with standard checkout sits at the £3,500 entry tier. Add hundreds of products, variants, subscription billing, ERP or stock-system sync, or a multi-vendor marketplace and you move toward £8,000+. We quote a fixed price up front so there are no surprises.
Is a custom shop cheaper than Shopify over time?
Yes, over the long run. Shopify costs roughly £828 to £4,600+ per year in subscription alone, plus a 0.5–2% cut of every sale on top of Stripe, plus paid apps. Over three years a Shopify shop can cost £2,500 to £15,000+ in platform fees. A custom shop from PBWD is a one-off from £3,500 with £0 monthly platform fees — hosting on Firebase runs under £10/month. Most shops break even versus Shopify inside 18–36 months, then save money every year after.
Do I own my online shop?
Yes. You own the code, the design, the customer data and the order history outright. It is your Firebase project, your Stripe account and your Xero account. Stop paying us and nothing disappears — unlike Shopify or Wix, where your store vanishes the moment you cancel the subscription.
Can you migrate my existing Shopify, Wix or WooCommerce shop?
Yes. We migrate products, images, prices, customer accounts and order history off Shopify, Wix or WooCommerce onto a custom Firebase build. We set up redirects so your existing rankings carry over, rebuild the design properly, and connect your Stripe and Xero. You keep your data and stop paying monthly platform fees.
Why don't you use Shopify or WooCommerce?
Shopify charges monthly fees plus a percentage of every sale and locks you into a rented platform. WooCommerce is a WordPress plugin that needs constant updates and security patches and breaks when plugins conflict. We build custom e-commerce on Google Firebase with Stripe. You own everything, pay no ongoing platform fees and never deal with plugin conflicts.
What payment methods do your e-commerce sites accept?
All major cards (Visa, Mastercard, Amex), Apple Pay, Google Pay and bank transfers via Stripe. Stripe charges 1.4% + 20p per transaction for UK cards and handles PCI compliance, so your customers' card data is always secure. We never add a cut on top of Stripe. We can also set up payment links and recurring subscriptions.
Does invoicing and stock sync with Xero automatically?
Yes. Every sale automatically generates an invoice in Xero — no manual data entry. Order comes in, Stripe processes payment, Xero creates the invoice, the customer gets their receipt and stock levels update. Your accounts stay reconciled and your accountant gets clean data.
Can I manage products and stock myself?
Yes. Every shop comes with an admin dashboard. Add products, set prices, manage variants and stock, view and export orders, and create voucher codes. No technical knowledge needed — if you can use a spreadsheet, you can run your shop.
How many products can the shop handle?
As many as you like. Your products live in Firestore, Google's scalable database — the same platform behind apps with millions of users. A few dozen products or tens of thousands, it stays sub-second fast. We explain the platform in detail on our Firebase web development page.
Do you build marketplace websites with multiple sellers?
Yes. Multi-vendor marketplaces with seller dashboards, commission tracking, product approval workflows and separate seller logins. Each seller manages their own products and orders through their own dashboard, while you keep oversight and take your commission automatically.
Ready to sell online properly?
Custom e-commerce. Stripe payments. Xero invoicing. Admin dashboard. No Shopify fees. No WooCommerce headaches. Just your shop, built properly.
