Your London Shopify store sells T-shirts beautifully and chokes the moment a clinic orders by purchase order
Custom Shopify development for a London, Ontario medical-supply, agtech, or manufacturing seller runs $20,000 to $90,000 over 6 to 16 weeks. A theme and template store handle direct consumer sales fine. You need custom the moment your buyers order on net-30 purchase orders, your products are regulated, or your pricing depends on volume, account, and contract, none of which a theme was built to do.
You launched on a Shopify theme and it looked great for direct-to-consumer orders. Then a London clinic tried to order medical supplies on a purchase order with net-30 terms and account-specific pricing, and the theme had no concept of any of it. Your real customers are not impulse shoppers; they are procurement departments at hospitals, agtech distributors buying by the pallet, and manufacturers reordering parts on contract.
Template stores assume credit-card checkout, flat pricing, and unregulated goods. Your catalog includes items with compliance requirements, your pricing is per-account and per-volume, and your buyers need quotes, approvals, and invoicing. Every one of those is a custom build on top of Shopify, not a setting you toggle in a premium theme.
Where the off-the-shelf tools fall short
- B2B buyers need purchase orders, net terms, and approval flows that themes do not support
- Account-specific and volume-based pricing cannot be expressed in a standard theme or app stack cheaply
- Regulated medical or agtech products need compliance fields, restrictions, and documentation themes ignore
- Your ERP (Enterprise Resource Planning) or inventory system has to drive stock and pricing, and template setups leave that integration to you
Custom shopify: what London teams actually get
Build custom on Shopify when your sales are B2B, account-priced, or regulated. A custom London Shopify build adds purchase-order checkout, per-account catalogs and pricing, compliance handling for regulated goods, and a real connection to your ERP and inventory, so the store sells the way your hospital, distributor, and manufacturing buyers actually purchase.

Timeline: what happens, and when
Exactly what you get
You get a Shopify store that sells the way London hospitals, agtech distributors, and manufacturers actually buy: purchase orders with net terms, per-account catalogs and pricing, compliance handling for regulated goods, and live sync with your ERP and inventory management software. Procurement buyers reorder in seconds instead of emailing a spreadsheet. Pair it with accounting software for invoicing and business intelligence dashboards for sales reporting.
How to choose a developer in London
Hire the team that asks how your buyers pay before it asks which theme you like. B2B and regulated Shopify work is a distinct skill, so favour a developer who has shipped purchase-order checkout and ERP-driven pricing, not just attractive consumer storefronts. Ask to see a store where a procurement buyer orders on net terms with account-specific pricing, and confirm they will integrate your inventory system rather than leave that to you.
- Purchase-order and net-term checkout with approval flows for procurement buyers
- Per-account catalogs and volume pricing so each customer sees their negotiated terms
- Compliance fields and ordering restrictions for regulated medical and agtech products
- Live integration with your ERP and inventory management software so stock and pricing stay accurate
- A buyer experience tuned for reordering and bulk purchasing, not one-off consumer checkout
- More expensive and slower than launching a premium theme this week
- Custom Shopify logic and apps need ongoing maintenance as the platform updates
- Heavy customization can collide with Shopify platform limits, occasionally pushing you toward Shopify Plus costs
- If you truly sell direct-to-consumer, a good theme plus a few apps is the cheaper right answer
- !They show only consumer themes; ask how they handle purchase orders and net terms
- !No ERP integration plan; ask how stock and account pricing stay accurate
- !They ignore product compliance; ask how regulated medical or agtech items are handled at checkout
- !They assume flat pricing; ask how per-account and volume pricing works
- !No plan for reordering buyers; ask how a procurement customer repeats a 200-line order

Frequently asked questions
Can Shopify even do B2B purchase orders?
Yes, with custom development. Standard themes assume card checkout, but Shopify can support purchase orders, net terms, approval flows, and per-account pricing when a developer builds those on top of it, often using Shopify Plus B2B features. That gap between what a theme does and what procurement buyers need is the whole reason London medical and agtech sellers build custom.
Why does regulated product matter for the store?
Because medical supplies and certain agricultural products carry compliance requirements, ordering restrictions, and documentation that a generic theme has no concept of. A custom build adds the fields, restrictions, and records you need at checkout, so you sell regulated goods correctly instead of bolting compliance on after the order ships.
Will the store stay in sync with our inventory?
It should. A custom London Shopify build integrates two-way with your ERP and inventory management software so stock levels, account pricing, and orders stay accurate in real time. Without that integration you get overselling and manual reconciliation, which is exactly the problem a theme-plus-apps setup tends to leave you with.
