Connecting WooCommerce to Exact Online
Off-the-shelf connectors for this integration range from €12 per month (xCore, 2026) to €145 per month (Conneqt, 2026) — the difference is in B2B functionality, not necessarily in reliability. For most shops an entry-level package is enough; a custom build, an indicative €1,500 to €15,000, comes into play with real-time requirements or your own business rules.

How do you connect WooCommerce to Exact Online?
With an off-the-shelf connector, a workflow tool or a custom integration on the APIs and webhooks of both systems. The standard route turns orders, customers and payments automatically into bookings or invoices in Exact Online and is set up within a few days. What stands out is the price spread: for functionality that looks comparable on paper you pay €12 to €145 per month — so it pays to first get a clear picture of what you actually need. How the custom-build calculation works is covered in what does an API integration cost?; what such a flow looks like you can see in the interactive Flow Lab.
WooCommerce differs from closed platforms in one fundamental way: it runs on your own hosting, among your own plugins. That makes the integration more flexible — webhooks give you real-time updates where many connectors work with a polling interval — but also more vulnerable to updates and plugin conflicts.

What syncs — and what doesn't?
Orders and customers carry across on every route; the differences are in speed, inventory and B2B pricing. And unlike a closed platform, your own WooCommerce environment — plugins, hosting, updates — also determines how reliable the sync stays in practice.
| Data | Off-the-shelf connector | Custom integration |
|---|---|---|
| Orders and customers | Yes | Yes |
| Refunds and credit notes | Yes — with most connectors | Yes |
| Real-time processing | Limited — many connectors pull orders on a polling interval of minutes to an hour | Yes — WooCommerce webhooks push orders within seconds |
| Sales orders and inventory | Limited — requires Exact Online Trade and a pricier connector variant | Yes, if your Exact licence allows it |
| B2B price lists and customer-specific pricing | Limited — only in the most expensive connectors | Yes |
| History before the start date | No | Optional |
Three questions that settle the choice.
Does an entry-level connector cover your fields and volumes?
Yes → pick the cheap package and be live within days; paying more for unused B2B features makes no sense. No → first decide whether you'll really use the pricier functionality before you scale up.
Do you need real-time?
No → a polling interval of a few minutes to an hour is perfectly fine for the bookkeeping. Yes → inventory across multiple channels or fast fulfilment calls for webhooks, so for a connector that uses them or a custom integration.
How stable is your WooCommerce environment?
Tightly managed, with staging and fixed update windows → every route works. Lots of plugins and ad-hoc updates → pick an integration with monitoring and a clear owner, otherwise every next update is a gamble.
The rule of thumb: pay for the functionality you demonstrably use, and don't leave reliability to chance — monitoring belongs with this integration, whichever route you choose.
Where this integration comes unstuck in practice.
Paying for B2B features you don't use
Between €12 and €145 per month there's a factor of twelve — for functionality that partly overlaps. First draw up the list of fields and processes you truly need, and only then compare; the most expensive package isn't automatically the right fit.
An update that quietly breaks the integration
WooCommerce runs on your own hosting: a plugin, theme or PHP update can stop the sync with no error message in your shop. Test updates on a staging environment and check after every update whether orders still come through in Exact.
Polling that's too slow for your inventory
If you also sell on marketplaces or in a physical shop alongside the webshop, a polling interval can cause overselling: the stock is already gone before the sync runs. For multichannel inventory you want webhooks or a real-time integration.
VAT and ledger set up only after go-live
The integration books exactly what you configure — even if that's wrong. Agree with your accountant up front which ledger accounts revenue, shipping costs and payment costs land in and which VAT codes apply, and test every scenario with a trial order.
What shops ask us up front.
What does an integration between WooCommerce and Exact Online cost?
Off-the-shelf connectors range from €12 to €25 per month with xCore (2026) up to €145 per month with Conneqt (2026); the difference is mainly in B2B functionality such as customer-specific pricing, not necessarily in reliability. A custom build on the API costs an indicative €1,500 to €15,000 one-off; a webshop-to-accounting integration usually sits at the lower end of that, an indicative €500 to €2,000.
How long does it take to set up a WooCommerce-Exact Online integration?
An off-the-shelf connector is usually live within a few days, including setting up ledger accounts and VAT codes and testing with a trial order. A custom build takes closer to a few weeks. With WooCommerce, budget extra testing time for your own environment: the integration has to keep working after plugin and theme updates too, so a test on a staging environment is part of the job.
What if the connector stops or hits its limits?
Your data always lives in WooCommerce and Exact Online themselves, so you lose nothing — only the flow stops. Both systems have a well-documented API, so you can switch to another connector or have the integration rebuilt as a custom build. You simply carry over your ledger and VAT setup.
Who manages and monitors an integration like this?
With an off-the-shelf connector the vendor manages the software, but your WooCommerce environment remains your own responsibility: a plugin or PHP update can quietly break the sync. Agree who receives error messages, who tests updates and who steps in. We manage and monitor custom integrations for a fixed monthly fee.
Do I need to move away from WooCommerce to another platform?
No. Mature connectors with Exact Online exist for WooCommerce, and WooCommerce's webhooks even make real-time custom builds perfectly feasible. The choice between platforms is a broader trade-off of management, cost and flexibility — not a requirement of this integration.
