Shopify Plus B2B vs BigCommerce B2B Edition

Both platforms now ship native B2B. The marketing pages look interchangeable. The real differences are price list modelling, catalogue segmentation, checkout extensibility and how each handles a buyer who is also a consumer — and those decide the build.

B2B Checkout: Net Terms, PO Numbers and Approval Chains

A B2B checkout is not a retail checkout with an invoice option bolted on. It has to carry a purchase order number, respect a credit limit the ERP owns, and route orders above a threshold to an approver — without becoming the slowest part of the buying process.

PunchOut Catalogues: Selling Into Enterprise Procurement

Large buyers do not shop on your website. They shop inside Ariba, Coupa or SAP, and they expect your catalogue to appear there. PunchOut is the protocol that makes your storefront a guest inside their procurement system — and it is usually a contractual precondition, not a nice-to-have.

Headless Commerce for B2B: When It Is Worth It

Going headless buys you control of the front end and costs you everything the platform used to do for free. For B2B there are three situations where that trade is clearly right, and a much larger set where a well-built themed storefront wins.

Migrating Subscriptions Without Losing the Subscribers

A subscription migration moves live billing relationships, not records. Get the payment token migration or the billing anchors wrong and the damage surfaces a full cycle later — as involuntary churn nobody connects back to the project.

MCP Servers for Commerce Operations, Not Demos
