Greatwill is Finnish consolidation software built for preparing consolidated financial statements under the Finnish Accounting Act (FAS, Finnish GAAP). It breaks the consolidation down into group events: each event is a short form, and the elimination entries, reconciliations and the consolidation worksheet are generated from the data entered in the forms. There is a form for every group event: founding and acquiring a subsidiary, intra-group income, expenses, receivables and payables, unrealised margins in inventory and fixed assets, intra-group dividends, translation differences of foreign subsidiaries, minority interests, the transfer of depreciation differences and tax-based reserves to equity and deferred tax, equity-method accounting for associates, and the sale or merger of a subsidiary. Each form asks only for what matters; exchange rates, tax effects and minority shares are handled automatically. The subsidiaries' own bookkeeping stays untouched. Each company prepares its financial statements in its own accounting software, and the finished statements are imported into Greatwill as files. They are mapped automatically to the FAS group chart of accounts, and accounts marked as intra-group are eliminated directly from the imported figures. A form filled in once carries over to the following financial years: goodwill amortisation, the unwinding of purchase price allocations and recurring eliminations are generated automatically for later periods. Reconciliation statements reveal forgotten or incorrectly filled forms, and every elimination entry can be traced back to the form it came from. The consolidation worksheet, the financial statements and the general journal and ledger are downloaded as Excel files, and auditors can be given read-only access directly in the system. Pricing is based on a base fee plus the forms the group needs, not on user counts or revenue. Data is stored in the EU. Greatwill Oy was founded in 2024 and is based in Helsinki, Finland.
