Desktop & Integrations
QuickBooks Desktop talks to Mutero through the Web Connector (QBWC) and the local desktop agent. Invoices and credit notes flow into the fiscal queue with idempotency keys so retries do not double-submit. When a receipt stalls, check tax mapping and customer TIN fields first — those are the most common ZIMRA validation failures — then inspect the desktop queue for the exact FDMS message.
