WooCommerce boekhouden plugin voor Acumulus

The Acumulus plugin connects your Woocommerce store to the Dutch SIEL Acumulus online financial administration application. It can add your invoices automatically or via a batch send form to your administration, saving you a lot of manual, error-prone work.

The Acumulus plugin:

  • Reacts to order status changes via actions.
  • Does have 4 admin screens: a register, settings, advanced settings, and a batch send screen.
  • Offers a meta box with an overview of the status of the invoice in Acumulus on the edit order screen.
  • Does not in any way interfere with the front-end UI.

The Acumulus plugin assumes that:

If not, this plugin is useless and will not do anything.


See the Acumulus forum.


  • Settings form
  • Advanced settings form
  • Batch form
  • Acumulus invoice status overview


  1. Install the plugin through the WordPress plugins screen directly or, alternatively, upload the plugin files to the /wp-content/plugins/acumulus directory manually.
  2. Activate the plugin through the ‘Plugins’ screen in WordPress.
  3. Go to the ‘Settings – Acumulus’ page (wp-admin/options-general.php?page=acumulus_config) to configure the plugin.
  4. If you do not have yet an account with Acumulus, you can apply for one by clicking on the register now button.
  5. Complete the (basic) configuration of the plugin.
  6. Go to the ‘Settings – Acumulus advanced settings’ page (wp-admin/options-general.php?page=acumulus_advanced) to configure the plugin.
  7. If you have set so, invoices for new orders are now automatically sent to your administration at Acumulus.
  8. You can use the ‘Woocommerce – Acumulus’ page (wp-admin/admin.php?page=acumulus_batch) to send a batch of (older) orders to Acumulus.
  9. To cater for specific use cases, the plugin does define some filters and actions, so you can intercept and influence the actions it performs. See the separate filters.txt for more information.

Goede plug-in en doet wat het moet doen. Zeker met de nieuwe toepassingen voor BTW vrij maakt het een stuk makkelijker
