B2B store with ERP integration

We build B2B stores wired into your ERP: real-time stock and contract prices per client, orders landing in the ERP as sales order drafts and the ERP staying the source of truth. Nobody retypes anything, that is the whole point.

What is a B2B store with ERP integration?

A B2B store with ERP integration is an ordering platform where the ERP stays the source of truth. The store reads live stock, contract prices and payment terms from the ERP, and every order a customer places lands back in it as a sales document. Nobody retypes anything; the office stops being a human API.

It is a different discipline than consumer eCommerce: company accounts with roles, per-customer price lists, credit limits and approvals. The storefront can be simple; the integration and the data contracts underneath decide whether the platform works.

The three numbers a B2B portal works for

A B2B build is judged in the back office, not in a lookbook. These move first.

Cost per order

CPO

Orders enter the ERP as documents, not as e-mails to retype. Sales reps sell; the office stops rewriting.

Errors from retyping

≈0

Live stock and contract prices at the moment of ordering: customers order what exists, at the price that applies.

Orders beyond office hours

24/7

Returning buyers place and repeat orders when it suits them. The portal keeps no business hours.

A B2B portal wired into the ERP or orders by e-mail?

Most wholesale still runs on inboxes and phone calls. This is what actually changes with a portal.

A dozen loyal customers and a few orders a week? A disciplined e-mail process may be enough. The Blueprint shows when the portal pays for itself.

B2B Store with ERP

The ERP is the source of truth, the store must respect that

B2B eCommerce fails when the store and the ERP disagree: a price the salesperson does not recognise, stock that exists in one system only, an order retyped with a typo. Our integration principle is strict: prices, stock, clients and terms live in the ERP; the store reads them live and writes orders back as drafts.

The hard part is never the API, it is the mapping. Which price list wins for which client, how reservations affect visible stock, what happens to blocked customers. The Blueprint answers those questions field by field with your ERP administrator at the table, before any code, which is why our integrations go live without surprises.

How we do it

A B2B + ERP build, week by week

A typical launch closes in about 9 weeks; the ERP analysis up front is what keeps that date honest.

Week 0

ERP Blueprint

Audit of ERP objects: products, price lists, stock, documents and permissions. Integration map, risks and a fixed quote.

Weeks 1–2

Foundation

Environments, the commerce core and company accounts with roles, plus the first read-only ERP sync: products and stock.

Weeks 3–5

The integration core

Contract prices, payment terms and order push into the ERP as sales documents, with error queues and retries.

Weeks 6–7

Customer portal

Quick ordering by code and CSV, order lists, one-click reorder, approvals and credit limits.

Weeks 8–9

Pilot and launch

A pilot group of real customers, sales team onboarding, then go-live with hypercare and Maintenance & Growth.

Who a B2B + ERP build is for, and who it is not for

A good fit when

  • Distributors and manufacturers with returning customers and repeatable orders that still arrive by e-mail and phone
  • The ERP is the source of truth and the office retypes into it by hand
  • Sales reps spend their days handling orders instead of selling

A poor fit when

  • Sales are purely project-based and every deal is negotiated from scratch
  • The ERP is mid-replacement: stabilise it first; the Blueprint can plan for the future API
  • A handful of customers with sporadic orders; process discipline is cheaper than a platform

FAQ

B2B store with ERP integration

Our ERP is old and has no API. Is integration possible?

Almost always, file exchange, database views or an integration layer are workable. Slower sync intervals are honestly stated in the Blueprint, not discovered after launch.

What happens if the ERP is offline?

The store degrades gracefully: catalog stays browsable, ordering queues or pauses per your rules, and sync resumes automatically. That behaviour is designed, not accidental.

Which ERP systems do you integrate with?

Any system with an API or file exchange, in practice mostly Polish ERPs and SAP. The Blueprint defines the exact field-by-field scope before the build.

Stays the ERP the source of truth?

Yes, prices, stock and clients live in the ERP; the store reads them and writes orders back. No second catalog to maintain.

How long does the ERP integration take?

It is built inside the standard engagement, a typical B2B store with ERP launches in about 8 weeks, integration included.

Which ERP systems do you integrate with?

The ones common in Poland and the EU: Comarch ERP, Subiekt, enova365, SAP Business One and others. If the system has an API or any structured export, there is something to talk about; the Blueprint verifies the details.

What if our ERP has no API?

File-based exchange on schedules still beats retyping: a slower sync rhythm, the same zero manual work. We have run integrations through staging tables and file drops where that was the honest option.

Can the portal run alongside e-mail orders?

Yes. Rollout is gradual: a pilot group first, then customer cohorts. E-mail does not disappear overnight; it just stops being the system of record.
