How to connect an e-shop with an ERP system

When the e-shop and ERP don't communicate, someone retypes orders manually — and makes mistakes. Connecting them via API removes this intermediate step and data starts flowing on its own.

The problem: two systems, one human between them

A typical scenario: an order arrives in the e-shop, someone retypes it into the ERP, checks the stock, issues an invoice and adjusts availability. Every step is time and a possible error. With dozens of orders a day it's a full-time job — and one typo is enough.

The solution: integration via API

Integration via API means the systems exchange data automatically. An order from the e-shop writes itself into the ERP, the stock updates, the invoice is issued and availability is reflected back in the e-shop. The human no longer retypes anything.

What is typically synchronized

  • Orders — from the e-shop into the ERP immediately after submission.
  • Stock and availability — a change in stock level is reflected in the e-shop.
  • Products and prices — a single source of truth, no discrepancies.
  • Invoices and documents — automatically into accounting.
  • Order status and shipping — synchronization with the courier and notifications to the customer.

What to watch out for

  • A single source of truth — agree which system „owns“ products and stock, so the data isn't overwritten back and forth.
  • Handling exceptions — what happens during an outage, a duplicate order or a return.
  • Bidirectionality — data often needs to be sent both ways, not just one.
  • API limits — every platform has its constraints that must be accounted for.

Reliability stands or falls precisely on these details. That's why integration is designed, not built blindly.

Related to warehouse and automation

Connecting an e-shop with an ERP is part of the broader process automation and goes hand in hand with warehouse digitalization. Together they form a chain where an order travels from the customer to accounting without a single manual retype.

FAQ

FAQ

Can any e-shop be connected with any ERP?

In most cases yes — either via the official API or via an intermediary if the system has no API. We'll determine the scope after mapping both systems.

What happens if one system goes down?

A good integration accounts for outages — data is queued and synchronized once the system is available again, so nothing is lost.

How long does the integration take?

Simple order synchronization is a matter of days to weeks; a complex bidirectional connection of stock, prices and accounting takes longer. We'll give an estimate after the analysis.
