Switching systems

Bring the whole ledger. Including the years behind you.

Chart of accounts, contacts, entries and open invoices all move across. You retype nothing.

Dinero, Billy, e-conomic · CSV and SAF-T · Nothing posted without your go-ahead

Four ways in. Same result.

If your old system has an API, Sparro reads your data directly with a key you create yourself. If it can only export a file, Sparro reads the file instead. Both roads end in the same place: everything is matched against the Danish standard chart and laid out as one review that you approve, before a single krone is posted.

The key is only used to read. Nothing is changed in your old system, and the key is deleted automatically once your documents have been fetched.

The fetch itself takes a couple of minutes, even on a ledger with many years behind it. The rest of the time is your own review.

The chart of accounts is matched, not guessed.

If you run the Danish standard chart of accounts, every account meets its counterpart on the number and there is nothing left to do. If only the names look alike, the match has to be very strong before Sparro dares use it. The rest lands with you.

  • Number match first. Accounts sharing a number in both systems move across 1:1 with no questions asked.

  • Name matching only well above a high threshold, and only against accounts of the same type as the old one.

  • In doubt, the account stays unmatched with up to three ranked suggestions, and the import cannot run until you have picked one.

This comes along. And this stays where it is.

An import should not pretend to do more than it can. So you get both lists before you start.

Comes along

  • The chart of accounts with your own account names, matched against the Danish standard chart.
  • Contacts with CVR, EAN and address, so invoices and bills know their counterpart.
  • Posted history, entry by entry, carrying the original voucher number as its reference.
  • Open invoices with due date and remaining balance, ready for the reminder flow.
  • VAT amounts exactly as they stood. They are copied, never recalculated.

Stays where it is

  • VAT periods you already reported from the old system are locked. They cannot be reported again from Sparro.
  • If your old system's document archive cannot be read, the PDFs stay there. Keep read access for the five years the law requires.
  • Open supplier bills are counted in the summary, but are not posted as debt in this round.
  • Products are read along and shown in the summary. The product catalogue itself arrives in Sparro later.

Do not cancel your old subscription until you have seen the numbers in Sparro. Switch to a free read-only account if the system offers one.

Nothing is posted until debit and credit agree.

The last step is a preview: how much is coming in, how it will be posted, and whether the trial balance adds up. If it does not, the button cannot be pressed. Sparro never adjusts a number to make it fit.

VAT through 30.06.2026 was reported from your old system. The period is locked.Run the import
  • You decide whether the whole history is aggregated into one opening balance, or this year's vouchers stay individually searchable.
  • Vouchers that do not balance are shown with number, date and difference. They are never closed automatically.
  • Run the import again and the same voucher is not created twice. Every line carries its own reference from the old system.
