Online store for a PVC hose manufacturer
A store where farms, workshops and food producers buy reinforced PVC hoses by the coil or cut to length — with company invoices, deferred payment for dealers and a CMS the manufacturer runs on its own.

The task
Replace a quickly assembled shop that showed €0.00 prices, broken photos and no legal pages.
The manufacturer sold through a hand-written PHP site and a separate shop. Our audit found product photos blocked by the site's own security policy, every price in the shop shown as €0.00 while checkout stayed active, an e-mail domain without an MX record — so enquiries were likely lost — and no privacy policy behind a form that collected personal data.
Business buyers needed more than a cart: net prices, a VAT invoice for every order, payment by transfer or on terms, repeat orders and order tracking. The manufacturer needed to edit products, prices and translations without a developer.
