The Acumulus plugin connects your OpenCart 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 events.
* Does have 4 admin screens: a register, settings, advanced settings, and a batch send screen.
* Does not in any way interfere with the front-end UI.

The Acumulus plugin assumes that you have an account with SIEL Acumulus, also see Overview of webshop connections. If not, this plugin is useless and will not do anything.
