KSeF in your company — we set up the process, not just issue invoices
From 1 January 2027 several things change at once: the obligation extends to the smallest taxpayers, and the KSeF number must be quoted when paying structured invoices. We review how your invoices flow today and get them to a point where no manual work is needed.
Invoices, KSeF and Comarch Optima in one office · Service in Polish, Ukrainian, English and Russian
What we check
- How and where your invoices are created today — software, spreadsheet, online shop, order panel.
- Whether purchase invoices received in KSeF reach your accounts without retyping.
- Whether KSeF data matches your ledgers and JPK files.
- Whether your Comarch Optima integration covers invoices, contractors and payments.
