Under German tax laws and GoBD guidelines, managing advance payments and client packages manually in spreadsheets is highly risky. Recording VAT (Umsatzsteuer) liabilities and tracking remaining client balances manually often leads to auditing issues.
Zenbooks customer wallets simplify upfront billing for German businesses. Load the client's balance in EUR (€). When they return, create the invoice and pay it using the wallet balance—calculating 19% VAT and generating a compliant invoice automatically.
