Which documents do I need to gather?

To get started, basic information and your most recent financial statement are enough: tax number, legal form, commercial register extract if available, your most recent tax return or balance sheet, and a list of your bank accounts. For ongoing bookkeeping, you'll also need monthly outgoing and incoming invoices, bank statements, cash reports, and receipts for entertainment expenses or vehicles. Employers additionally need employment contracts, health insurance assignments, and time records. You'll find a breakdown by client group on the Documents page.
