Over deze plugin.
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:
You have installed WooCommerce.
You have an account with SIEL Acumulus, also see Overview of webshop connections.
If not, this plugin is useless and will not do anything.
Installation using composer and GitHub Note: this is only recommended for developers, not if you only want to use this plugin in your webshop.
Open a cmd prompt and go to the plugins folder: cd wp-content/plugins
