About this plugin
An independent integration built by Arbictus OÜ. It is not affiliated with, endorsed by or
sponsored by Registrite ja Infosüsteemide Keskus (RIK), the operator of e-Financials /
e-Arveldaja, nor by Automattic, the owner of the WooCommerce trademark. “e-Financials”,
“e-Arveldaja” and “WooCommerce” are used here only to describe what this plugin connects to.
Background sync so checkout stays fast. Once an order is paid (or marked completed) the plugin:
- Upserts the customer as an e-Financials client.
- Ensures every ordered product exists as an e-Financials product.
- Creates and registers the sale invoice.
- Records the payment (cash fields and/or a bank transaction), gateway-agnostic.
- Optionally delivers the invoice to the customer by email or e-invoice.
- Issues credit invoices on full and partial refunds.
Merchants get a settings screen, an order list column, an order metabox with the invoice PDF,
manual order actions and an optional note on customer emails.
The plugin is compatible with WooCommerce High-Performance Order Storage (HPOS) and queues its
work through Action Scheduler, so no API call ever blocks a shopper.
