We introduced a custom cart feature within Pocketknife, to support high volume B2B ordering, bulk ordering and real time pricing logic - ensuring performance and reliability at scale. Our feature removes friction from bulk ordering - making large, complex purchases fast, reliable, and scalable for B2B customers.

This Shopify piece on B2B ecommerce challenges highlights how complex ordering workflows can get:

But one thing we see often (especially in B2B) is the scale of the cart itself. The challenge is that Shopify’s native cart isn’t designed for that scale out of the box.

Shopifys native cart has a 500 line item limit.

What did we build?

Our feature removes native constraints, enabling the reliable processing of large-scale orders, without predefined line item limits.

A feature where B2B clients can have:
• No item limit
• Bulk ordering

What it solves:
Removes limitations around large orders, allowing hundreds of line items to be processed reliably. This is essential for clients like Modern Star, where large cart sizes, real-time ERP-driven pricing, and multiple B2B storefronts demand performance, data consistency, and resilience across the ordering workflow.

Where it adds value:
Particularly useful for B2B businesses managing bulk or repeat ordering, where speed and accuracy matter.

For businesses placing hundreds of items per order, this creates performance issues and friction in the ordering process. This is particularly valuable for clients like Modern Star, who operate multiple B2B commerce sites under a single ecosystem.
