How ThatFiscal Works — Cloud Fiscalisation Explained
Overview. ZIMRA requires every VAT-registered business to fiscalise its invoices — sign them digitally and submit them to the Fiscalisation Data Management System (FDMS) in real time. ThatFiscal is a virtual fiscal device in the cloud that does this for you:
Your System Raises an Invoice
In Odoo, Zoho Books, QuickBooks, Sage, Excel — wherever you already work. Nothing about your workflow changes.
ThatFiscal Signs & Submits It
We sign it with your registered device key, chain the hash to the previous receipt, auto-fill any missing HS codes, and submit to ZIMRA within seconds — invoices and credit notes.
The Proof Comes Back
QR code, verification code and fiscal numbering land in your portal and on your invoice. Your customer can verify it on the ZIMRA site instantly.
What makes us different: no software to install, no plugin portals, no per-machine add-ins. One account, one API key, and most connections are live in minutes — the comparison table below shows the exact path for every system.
