# Magento ERP integration that reports one number, not three.

> E-commerce system integration between the storefront and everything behind it: ERP and SAP, CRM, PIM, warehouse, accounting, payment gateways and carriers. Two-way, queued and retryable — so stock, prices and orders agree across every system that reports them.

## What gets connected.

Adobe Commerce documents integration around products, customers and orders. That is exactly where the money leaks when it is done badly.

- **ERP and SAP integration** — Two-way sync of products, prices, stock, customers and orders with SAP, Odoo, Logo, Netsis or an in-house ERP — with an explicit source of truth per field.
- **Real-time inventory synchronization** — One stock figure across store, warehouse and ledger, with reservation logic so a product cannot be sold twice while the sync is in flight.
- **Custom payment gateway integration** — Direct integration with local banks and providers — instalments, 3-D Secure, refunds and reconciliation — including gateways with no official Magento module.
- **Shipping and logistics integration** — Carrier handover, label generation, tracking updates and returns, so a shipment moves from paid order to courier without anyone retyping an address.
- **Order management and CRM/PIM** — Order state mapping into OMS, CRM and accounting, and product data flowing out of a PIM — with retries, dead-letter handling and a log a human can actually read.

## When the systems stop agreeing.

Integration failures are rarely loud. They show up as a customer service call, a stock write-off, or a month-end that does not balance.

- **Magento inventory synchronization problem** — The site sells what the warehouse no longer has, because the sync runs on a schedule instead of on an event.
- **Orders arrive in the ERP twice** — No idempotency key, so a retry after a timeout creates a second document and a second invoice.
- **Prices differ between store and ERP** — Two systems both believe they own the price field, and the last writer wins at random.
- **The payment gateway has no Magento module** — A local bank or provider only ships an API document, and the checkout has to be built against it properly.
- **Shipments still get typed by hand** — Someone copies addresses into the carrier panel every morning, and every typo becomes a failed delivery.
- **Nobody can see why a sync failed** — There is no queue, no retry and no log — only a support ticket from the customer who noticed first.

## Integrations already running in production.

- **Edip Saat (edipsaat.com)** — Two-way sync between store, ERP, warehouse and accounting so prices and quantities update live and nothing is sold that is not there.
- **Frankenspalter (frankenspalter.ch)** — ERP feeding a Magento core that has to keep taking orders while the sync runs — queue design as much as integration work.
- **SBL Beauté (sblbeaute.com.au)** — Payments and calendar wired into one booking application, so a paid appointment and a held slot are the same event.

## Questions people ask.

**Which ERP systems have you integrated?**
SAP, Odoo and in-house ERPs, plus warehouse and accounting systems on both sides of the sync. The pattern matters more than the brand: an explicit source of truth per field, an event that triggers the sync, a queue that can retry, and a log that shows what happened.

**Can you integrate a system that has no API?**
Usually yes. Older ERPs are reachable through a database view, a file drop, a SOAP endpoint or a small adapter service installed beside them. The adapter becomes the documented boundary, so the commerce side never has to know how strange the other end is.

**How long does a first integration take?**
A single well-defined flow — orders out, or stock in — is usually weeks, not months. The time goes into the edge cases: partial shipments, refunds, cancellations and the retry behaviour when the other side is down. Those are the parts that decide whether it still works in month six.
