Ledger and journal
A ledger that cannot be rewritten
Enter postings in the journal with account, contra account, VAT code and dimensions. Attach a voucher or generate an internal one, then post the whole batch at once.
Once posted, an entry gets a gap-free number, a registration time and the user who made it. It cannot be edited or deleted. Mistakes are corrected with a reversal, and a SHA-256 hash chain reveals any change to the books. You can verify the chain with one click.
- Journal (kassekladde) with batch posting
- Gap-free numbering, time and user on every posting
- Corrections as reversals, never edits
- A voucher on every posting, kept for five years
VAT
VAT calculated on every line
PolyOmi ships with the official Danish VAT codes, including reverse charge, partial deduction and energy duties. VAT is calculated per code on every sale and purchase.
For each period the VAT return is prepared with all boxes and rubrics A, B and C, ready to copy into the tax portal. When you settle the period, the VAT is posted and the period is locked.
- Monthly, quarterly or half-yearly periods with deadlines
- Rubrics A, B and C for EU and non-EU trade
- Settlement posts the VAT and locks the period

Questions about bookkeeping
Does PolyOmi meet the Danish Bookkeeping Act?
PolyOmi is built to meet the Danish Bookkeeping Act (bogføringsloven) and the Danish Business Authority's requirements for digital bookkeeping systems. It is a self-hosted system that is not registered with the authority, so as the owner you are responsible for meeting the requirements, for example keeping an off-site backup. The compliance checklist shows what is in place and what needs attention. Read more about PolyOmi and the Danish rules.
Can I edit or delete a posting?
No. Posted entries are final, as the law requires. You correct a mistake with a reversal, and both entries stay visible in the ledger.
Can I file the VAT return directly from PolyOmi?
PolyOmi prepares the VAT return with all boxes and rubrics A, B and C, ready to copy into the tax portal. Settling the period in PolyOmi posts the VAT and locks the period.
Can I move my books from another system?
You enter opening balances in the journal, and products can be imported from CSV. If you need help with a move, contact us.
Do I need an accountant?
PolyOmi gives you and your accountant the same ledger, reports, draft annual report and SAF-T file. Many companies still use an accountant for the annual report and tax, and PolyOmi makes that work easier.
