Who this is for

Retailers on or moving to Shopify Plus, multi-brand groups, international expansions and Magento or legacy replacements.

Why this price is worth it

  • Multiple stores, markets, currencies and languages configured properly
  • Checkout Extensibility and Shopify Functions for custom pricing, shipping and discounts
  • ERP, WMS, PIM, accounting and marketplace integrations engineered, not bolted on
  • Delivered by senior engineers at a fixed price — without the enterprise-agency overhead

Cheaper quotes usually strip out design, copy, SEO or testing and add them back as extras — or leave you with something you can’t build on. Bigger agencies charge for account managers and overhead. This price is the work, done properly, once.

Everything included

  • Shopify Plus setup or migration
  • Multi-store, markets, currencies
  • Custom checkout + Shopify Functions
  • Custom theme and design system
  • ERP / WMS / PIM / accounting
  • Amazon, eBay, Google, Meta feeds
  • Full SEO redirect mapping on migration
  • Docs, training, SLA support plan

How it works

  1. Discovery call — products, margins, suppliers, shipping and what customers search for.
  2. Fixed-price proposal — pages, product volume, apps and integrations written down.
  3. Design — home, collection and product templates approved before build.
  4. Build & configure — products, payments, shipping, tax, emails, reviews, SEO.
  5. Test orders & launch — we place test orders with you, then hand over the store.

Questions people ask

Do we need Plus?

Usually only above ~£1m revenue or when custom checkout/B2B is essential — we’ll tell you honestly.

Magento migration?

Yes, with a complete redirect map.

Fixed price on this size?

Thorough discovery, written scope, change requests quoted separately.

Why choose BDUK over a cheaper developer?

Because the price includes design, engineering, SEO, testing and handover done by one senior UK team at a fixed price — cheaper quotes usually leave out half of that and add it back as extras, or leave you with something you can’t build on.

Is the price really fixed?

Yes. The proposal lists every deliverable; that is the price. Anything outside it is quoted before we do it, never slipped in.
