The challenge
Compliancewithout the daily chore.
For a shop owner, fiscalisation is not a project — it is a task that comes with every single order.
The goal was to let WooCommerce shops connect to KigoKasa once and stop issuing invoices by hand.
What we built
Invoices issuedat checkout.
- The plugin integrates into the WooCommerce checkout process
- Each order is sent to the KigoKasa service through an API request
- KigoKasa generates an invoice or offer with Croatian fiscalisation
- A demo shop lets merchants try the integration before going live
- The documented KigoKasa API supports custom setups

The result
Shops stay compliantwithout changing how they sell.
Merchants keep their WooCommerce shop as it is, while fiscalised invoices are created automatically for each order.
