Invoice automation

Replace days of manual invoicing with one click at month end.

We connect your invoicing software (Számlázz.hu, Billingo) to the spreadsheets, web shop or internal system you already use. The system calculates line items, VAT and totals, and your team only has to approve them.

Sound familiar?

  • Month-end invoicing takes days, client by client
  • Numbers are copied by hand from spreadsheets into the invoicing software
  • One typo or wrong VAT rate means a cancelled invoice
  • Every client has different rates and different line items
  • Payments from your web shop or app still need invoices issued by hand

Solution

What we automate

  • Számlázz.hu and Billingo integration

    A direct connection to your invoicing software, including e-invoices and proforma invoices.

  • Bulk invoices from Excel

    Every monthly invoice created from your existing spreadsheets in one step.

  • Custom pricing rules

    Per-client unit prices, surcharges, exchange rates and VAT handling, exactly as in your contracts.

  • Review before sending

    An editable draft and the official PDF preview of every invoice.

  • Invoices after payment

    Orders paid in your web shop or through Stripe are invoiced automatically.

  • Logs and partner records

    A searchable log of every invoice issued and up-to-date customer details.

Cash processing and cash-in-transit: monthly invoicing in minutes instead of days

The GuardAgent batch view with the companies waiting to be invoiced and an editable invoice draft
Before
Every month the invoices were built by hand in Számlázz.hu, client by client: deliveries, fuel surcharge, cash processing fees, currency and change supply, each with its own VAT treatment.
Solution
GuardAgent reads the two monthly Excel files, calculates every line item, matches each client to the partner list and prepares editable drafts with a Számlázz.hu preview.
Result
The whole monthly batch goes out as e-invoices in one step after review, calculated the same way every time.
Safety
Two-factor sign-in, a proforma test mode before going live, and a searchable log of every invoice sent.

FAQ

Frequently asked questions

Your question isn’t here? Ask us directly

  • We have built production integrations with Számlázz.hu and Billingo, and we can connect to any other invoicing software that offers an API.

  • Yes. The system reads the files you already use, so your team does not have to change how it works.

  • Every invoice appears as an editable draft before it is sent, with the official PDF preview from your invoicing software. A new setup can also run in proforma test mode first.

  • Two-factor sign-in, encrypted connections, and the invoicing software key never leaves the server.

  • It depends on scope. After the free assessment you get a fixed price in writing, which does not change without your approval.
