THE SHORT ANSWER

Custom ecommerce in short.

Custom ecommerce is a store built around complex requirements that standard platforms handle poorly.

WHO IT IS FOR
Businesses with large catalogues, customer-specific pricing, portals, quotations or heavy integrations.
WHAT IS INCLUDED
Architecture, B2B features, ERP and CRM integration, workflow automation and scaling.
BEFORE YOU CHOOSE
It takes longer and costs more than a standard platform, so confirm the requirement before choosing it.
WHEN CUSTOM MAKES SENSE

Custom is the answer when the platform becomes the problem.

Shopify and WooCommerce suit most stores. Custom ecommerce makes sense when you’re working around them more than with them. These are the signals.

CATALOGUES + PRICING

Thousands of products. Every customer’s price.

Technical catalogues with deep categories and specifications, and a pricing engine that applies contracts, tiers and quantity breaks for each account in real time.

B2B + CUSTOMER EXPERIENCE

Built for the way businesses buy.

Business buying involves accounts, approvals, quotes and repeat orders. We design those workflows into the platform instead of bolting them on.

COMPANY BUYING

Ordering built for business customers.

Company accounts with multiple buyers, contract pricing, quick ordering and payment on account — designed for repeat, high-volume purchasing.

  • Company accounts and branches
  • Contract and tiered pricing
  • Quick order by SKU and CSV upload
  • Pay on account with credit limits
