ERP integration for your online store

NMNorthMountain 30 May 2026 7 min read

Connecting your store to your ERP or accounting system means products, prices, stock and orders flow automatically between them. No double entry, no overselling, no end-of-day reconciliation by hand.

What integration actually syncs

  • Products & prices: maintained in one place, pushed to the shop.
  • Stock levels: updated so you never sell what you do not have.
  • Orders: sent to the ERP for fulfilment and accounting.
  • Customers & invoices: created automatically, ready for the books.

Why it is worth it

Manual data entry between a shop and an ERP is slow and error-prone. Integration removes a whole category of mistakes — wrong prices, oversold stock, missed orders — and frees your team from copy-paste work. The bigger your order volume, the faster it pays for itself.

One source of truth: decide where each piece of data "lives" (usually the ERP) and let the shop mirror it. Two systems both claiming to own stock is how chaos starts.

How it is built — and what to avoid

Most ERPs expose an API or support scheduled file exchange. We build a reliable sync with retries and logging so a hiccup never silently drops an order. Avoid brittle one-off scripts with no monitoring — that is how stores quietly desync for days.

Frequently asked questions

Which ERP and accounting systems can you integrate?
Most that expose an API or structured export — common European accounting and ERP tools included. If it has an API or scheduled file exchange, we can usually connect it.
Is the sync real-time?
It can be near real-time for stock and orders, or scheduled for less time-critical data. We match the frequency to the cost and the business need.
What happens if the ERP is briefly down?
A well-built integration queues changes and retries, so nothing is lost. Orders are never dropped — they sync as soon as the connection is back.

Tired of double data entry?

We connect your store and ERP so data flows by itself — reliably, with monitoring.
