System documentation
Last updated: 4 October 2026
How the books in Inzenda are organised: how a business event becomes a voucher (verifikation), how the vouchers are numbered, how a correction is made and how the books are kept. The Swedish Bookkeeping Act (1999:1078), chapter 5, section 11, asks for this description (systemdokumentation) and for a description of how each entry was processed (behandlingshistorik).
1. From transaction to voucher
Every transaction you record (by hand, from a bank file or an SIE file, an employer declaration or a year total) becomes a voucher at the same moment. Its lines are booked on BAS accounts that the category decides; you never pick an account yourself. The lines come from the same rules as the annual report and the tax return, so the books and what is filed cannot differ.
- The voucher shows when it was recorded and by whom, when the event happened, what it concerns, the amount, the counterparty and a voucher number (chapter 5, section 7).
- The receipt or invoice you attach is the voucher's supporting document.
2. Numbering
Vouchers are numbered in one series per fiscal year, A1, A2, A3 and so on, in the order they are recorded and without gaps. A number is never used twice. Opening balances have their own series, IB, as they are not business events.
3. Corrections and deletions
Nothing that has been booked is overwritten or erased (chapter 5, section 5). Editing a transaction creates a correction voucher that reverses the old lines and books the new ones. Deleting a transaction creates a reversal (makulering) of all its lines. The database itself refuses to change or delete vouchers and history.
- Every transaction has a history: every version, who made the change and when, and what changed.
- Corrections of earlier years (for example a cost missing from last year's accounts) are kept with who and when, and change the year's opening balances through a new voucher in series IB.
- An attachment added to the wrong transaction can be removed with "Wrong attachment, remove". The file is deleted, and the history shows who removed it, when, the file's name and why. It is the only attachment deleted before the retention period ends.
4. Opening balances and year-end
The year's opening balances come from last year's annual report, your answers about the year that went by and the corrections of earlier years, exactly as the year's report computes them, and are booked as a voucher in series IB. The year-end entries (depreciation from the asset register, the VAT settlement, tax and the year's result) are computed in the annual report and are not booked as vouchers.
5. Printouts and export
Under Transactions, Export books, each fiscal year has:
- General journal, grundbok (PDF): the vouchers in the order they were recorded, with every line (chapter 5, section 1).
- General ledger, huvudbok (PDF): per account the opening balance, the year's vouchers and the closing balance (chapter 5, section 1).
- An SIE 4 file per SIE file format version 4C, with the chart of accounts, opening and closing balances, results and every voucher. Other accounting programs and auditors can read it.
- All the books as JSON and CSV: vouchers, transactions and history.
6. Retention
The accounting records (vouchers, history, transactions, receipts, annual reports and tax returns) are kept until 31 December of the seventh year after the end of the calendar year in which the fiscal year ended (chapter 7, section 2), also when you close the company in Inzenda. The database is in the EU (Neon Postgres, Frankfurt). Once the retention period has ended, the books are deleted automatically.
7. Responsibility
The company is required to keep books and is responsible for every business event being recorded and for its documents being correct. Inzenda is the tool that keeps the books.
