erarium

The invoice arrives. The journal entry is already waiting.

erarium reads your clients' received invoices, checks them and proposes the booking. The accountant reviews and confirms, and the export goes to Vasco.

The path of one invoice

  1. It arrives on its own

    The client sends it to their invoice address, uploads it in the portal, or you drop it into the app. ZIPs and e-invoices too.

  2. Read and checked

    Supplier, amounts, VAT rates and the VAT ID against VIES. What doesn't match is flagged, never hidden.

  3. A proposed booking

    Accounts follow your rules for that client. Correct it once and it remembers.

  4. You confirm

    Enter after Enter through the queue. Nothing is booked without the accountant.

  5. Export to Vasco

    Journal entries as KN-21, with the bank statement and the VAT return for the same month.
