Invoices straight from the booking
Your accountant retypes every booking into another program. We build invoicing into your booking system: VAT invoices from each sale, corrections, a register and e-invoicing where the law asks for it.
The prototype and the quote are free, with no commitment.

The problem
What goes wrong without it?
Business customers want an invoice for every booking. Someone copies the data by hand, and mistakes reach the tax office.
E-invoicing laws, such as KSeF in Poland, make a separate invoicing tool one more system to connect.
What we build
Built the way your business works
Pick what fits. If your rule is not here, we build that one too.
Invoice from a booking
A VAT invoice issued when the booking is paid, with the customer's company details from the booking form.
Numbering and corrections
Gapless numbers per series and year, correcting invoices and a register for your accountant.
National e-invoicing
Invoices sent to Poland's KSeF and similar systems, with receipts kept beside each invoice.
Your accounting tool
Invoices exported to the accounting program you already use.
Compared with SaaS
How is this different from a booking tool?
A tool gives everyone the same setting. Your own system follows your rules.
Work
In a SaaS tool: Invoices issued in a separate tool, by hand.
In your own system: Issued from the booking, with no retyping.
Law
In a SaaS tool: E-invoicing waits for the platform to support your country.
In your own system: Built for the rules where you operate.
