Accounting for Swedish groups of companies

Every company in the group, reconciled to zero.

Koncernbok keeps the books for a whole group in one place – bank, payroll, year-end and the auditor's binder – built on the Swedish Bookkeeping Act from the first line of code.

What it does

One set of books per company, one view of the group.

Each company keeps its own ledger and its own database. Koncernbok ties them together where the group needs it – intercompany balances, consolidation and a single year-end routine.

A ledger that can't be rewritten

Verifications are append-only and hash-chained. A mistake is corrected with a new verification that points to the old one – as the Bookkeeping Act requires.

Bank, down to the öre

Statements come in and meet the ledger. What's left is one work list grouped by cause, with bulk and partial matching and suggested postings for the rest.

Runs alongside Fortnox and Bokio

Mirror the books you already keep, move over at your own pace, and send corrections back with a reference so both systems agree.

Payroll and employer returns

Schedules, absence and the Annual Leave Act, salary runs with corrections and retroactive pay, and the monthly AGI file for Skatteverket.

Year-end as a guided path

Checklist, account reconciliations, accruals, tax and INK2, and a K2 annual report produced as an archivable PDF.

Your shops and web shop, booked

Point-of-sale Z reports, WooCommerce orders, Svea and card settlements become verifications every night – with the trail back to each order.

Audit-ready

The auditor's binder, kept by the system.

Thirty-three areas in the order an auditor works through them – bank, loans, receivables, inventory, payroll, tax, equity, related parties, events after the balance sheet date – each showing what is done and what is missing.

  • Bank confirmations and loan statements uploaded once, attached where they belong.
  • One download: a folder per area with reconciliations, original files and a SHA-256 checksum for every file.
  • A time-limited, read-only auditor login with two-factor sign-in. Every page view is logged.
Progress

In daily use, and honest about what's next.

Koncernbok runs the books of four companies in its own group, and the 2025/26 year-end is being closed in it. Every release passes more than 2,400 automated tests first.
