API
Invoices by API
Create and send fiscal invoices to the national e-Invoice system programmatically or in one click — numbering handled, status tracked back from the authority.
invoicing + accounting, one system
Issue the invoice by API. The books post themselves.
Generate invoices through the national e-Invoice API; the VAT, totals and ledger entry compute themselves.

how it works
Three steps, and the math happens on its own.
01
Connect
Link the company's fiscal account once. ActiveCont talks to the national e-Invoice API on its behalf — no portal logins per document.
02
Generate and send
One API call, or one click, issues the invoice to the tax authority with series, numbering, VAT and totals computed for you.
03
Books post themselves
The sale, the VAT and the receivable become a balanced entry automatically. The accountant reviews a ready ledger.
Invoicing and accounting as one system, not two.
Dt = Ct
Accounting, computed
Every document becomes a balanced double-entry on its own. The numbers are worked out, not keyed.
5342
VAT and filing
Register and return built from the entries, reconciled, and submitted.
531
Payroll and staff
Salaries accrued and paid, contributions computed, each run posted automatically.
242
Bank and close
Statements matched line by line; depreciation and the month-end close run as a guided sequence.
why now
The invoice went electronic, and gained an API. Software can issue it now — and models read a fiscal document as well as a junior accountant. The manual bridge between them stops being necessary.

That is the edge: a built-in first customer, a direct channel to other accounting firms, and a hard-won grasp of the tax rules most software gets wrong.
