Improvement v0.25.0
v0.25.0 — JPK_FA on demand: hand your invoices over as one file
Generate a JPK_FA file of your issued invoices for any date range and download it — for your accountant, or when the tax office asks. Invoices already in KSeF are left out, because the office already has them.
July 23, 2026 Invoices
When your accountant or the tax office asks for your invoices as a JPK_FA file, you can now produce it yourself in a couple of clicks.
- Any period you need. Pick a from–to date range — a month, a quarter, or an arbitrary span — and Biurko builds the JPK_FA(4) file from the invoices you issued in it.
- KSeF invoices left out. Anything already sent to KSeF is skipped — the tax office already holds those. The file covers the documents outside KSeF, which is exactly what a JPK_FA request is about during the 2026 transition.
- A download, not a filing. JPK_FA is provided on request, never on a schedule, so this is a clean download — no signing, no gateway. Each file is kept, so you can pull it again.
Fill in your company's registered address once in Settings → Company (street, building and apartment number) and the file is ready whenever it is asked for.
