PunchOut Integration for B2B eCommerce
cXML and OCI PunchOut so your large customers can buy from your store through their own procurement system.
PunchOut is how enterprise buyers purchase: from inside their own procurement platform, they punch out to your store, build a cart, and send it back as a requisition for approval. If your biggest customers use Coupa, SAP Ariba, or similar, PunchOut is often a requirement to win or keep their business. I build cXML and OCI PunchOut integrations, including the catalog, the punch-out session, and purchase order handling, so procurement-led customers can buy from you without leaving their system.
& custom builds
My integration track record
I build the pieces PunchOut depends on in production: B2B catalogs, contract pricing driven from an ERP, and order flow, including the Options ERP platform behind Impact Office Supplies. PunchOut connects those to enterprise procurement systems.
What I build with PunchOut
The PunchOut integration work I most often take on. If yours sounds like one of these, we should talk.
cXML & OCI PunchOut
The two standards enterprise procurement uses. I build the punch-out session, the catalog hand-off, and the cart return so a buyer can move from their procurement system into your store and back with an approved order, without rekeying anything.
Customer-specific Catalogs & Pricing
Each procurement customer sees their negotiated catalog and contract pricing when they punch out, driven from your ERP so it is always the price you actually agreed.
Purchase Order Handling
Requisitions approved in the buyer's system come back to you as purchase orders, mapped into your order flow and ERP so they are fulfilled like any other order without rekeying.
Win & Keep Enterprise Accounts
For many large buyers, no PunchOut means no order. Supporting it properly is often what puts you on their approved supplier list and keeps you there.
A PunchOut integration built to last
The same approach behind every integration I ship, from the first conversation to the years of maintenance that follow.
Scope & map
We map exactly what needs to move between PunchOut and your store: orders, stock, pricing, customers, and where the awkward edge cases hide.
Build for redundancy
I build the integration around the failure modes: retries with backoff, idempotent writes, and reconciliation, so it holds up when the API has a bad day.
Test & reconcile
Tested against real data in a safe environment, with reconciliation reporting that proves PunchOut and your store actually agree before go-live.
Monitor & maintain
Monitoring and alerting from launch, so failures surface immediately, and the same developer who built it is the one who keeps it running.

Common PunchOut Integration Questions
What is PunchOut and why do I need it?
PunchOut lets a buyer shop your store from inside their own procurement platform. They punch out to your site, build a cart, and send it back as a requisition for internal approval, which then returns to you as a purchase order. Large organisations mandate this so all spend flows through their approved systems. If your biggest customers use procurement platforms, PunchOut is frequently a condition of doing business with them.
Which procurement systems does PunchOut work with?
The common ones are Coupa, SAP Ariba, Oracle procurement, and similar platforms, which speak the cXML or OCI PunchOut standards. Building to those standards is what lets your store connect to a buyer's procurement system regardless of which specific platform they run.
Can each customer see their own pricing through PunchOut?
Yes, and they usually must. Procurement-led buyers expect their contract catalog and negotiated pricing when they punch out, driven from your ERP so it reflects what was actually agreed. Getting this right is central to PunchOut being useful rather than just technically present.
Can PunchOut work with Shopify?
Yes. PunchOut is a B2B procurement capability rather than a native storefront feature, so it is built as a custom integration layer around your store and ERP. That is true whether you run Shopify, Adobe Commerce, or a custom platform. The catalog, the punch-out session, and the purchase order return all need to be implemented to the cXML or OCI standard, which is exactly the kind of work I do.
