## Skildring

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](https://wordpress.org/plugins/woocommerce/).
 * You have an account with [SIEL Acumulus](https://www.siel.nl/acumulus/), also
   see [Overview of webshop connections](https://www.siel.nl/acumulus/koppelingen/webwinkels/WooCommerce/).

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.

 1. Open a cmd prompt and go to the plugins folder: cd wp-content/plugins
 2. Download the zip from https://github.com/SIELOnline/Acumulus-for-WooCommerce, either:
 3.  * The latest version: https://github.com/SIELOnline/Acumulus-for-WooCommerce/archive/
       refs/heads/master.zip
     * A specific version, e.g.: https://github.com/SIELOnline/Acumulus-for-WooCommerce/
       archive/refs/tags/7.6.5.zip
 4. Extract the zip and rename the folder Acumulus-for-WooCommerce-[master|7.6.5] to
    acumulus
 5. cd acumulus
 6. composer update –no-dev

Note this won’t install the test classes from WooCommerce and WordPress that are
required by our own tests.
 Installing the test environment for this plugin is yet
to be described here.

## Installasjon

 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 yet have 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](https://plugins.svn.wordpress.org/acumulus/trunk/filters.txt)
     for more information.

Nooit de moeite genomen om een review te schrijven. Maar het moest er toch een keer
van komen, want ik heb Acumulus al bijna 10 jaar in gebruik naar volle tevredenheid!

 [webwitnl](https://profiles.wordpress.org/webwitnl/) 1. november 2024

De Acumulus API was van de week uren down, en haalde de hele backend van wordpress
onderuit. Ze hebben hierover helemaal niks gemeld, wat bizar is. Het moet bovendien
dan niet de backend onderuit halen, maar ze menen zich ook al dagen in stilzwijgen
te moeten hullen over dit bugreport. Dit is een totaal verkeerde instelling en maakt
deze plugin onbetrouwbaar.

Programma dat alles doet wat je nodig hebt. Gaat er ergens eens iets mis dan is 
de support geweldig!

Uitstekende plugin die precies doet wat «ie moet doen. Er zijn erg veel opties, 
dus het duurt ongeveer een half uurtje om alles in te stellen. Verder goed om te
weten dat het e-mailadres waar vanuit facturen verzonden worden beperkt configureerbaar
is in Acumulus. Desalniettemin uitermate tevreden, zeker in vergelijking met alternatieven
die ik eerder heb gebruikt.

Behalve dat je toch «n tikje inzicht in boekhouden nodig hebt, zeker als je ook 
buiten NL verkoopt, is het erg toegankelijk/relatiev makkelijk… technisch zonder
meer probleemloos.
