FDMS developer sandbox
ZIMRA FDMS Sandbox for VFD developers.
Practice Online fiscalisation — register devices, submit receipts, and close fiscal days against an FDMS-compatible gateway. Free Mutero account · no subscription required.
Homologation and production still use ZIMRA Live — this sandbox is Mutero-hosted for development.
Build against FDMS Online before you go live.
Mutero's ZIMRA FDMS sandbox mirrors the Online protocol your Virtual Fiscal Device must speak — verifyTaxpayerInformation, registerDevice, openDay, submitReceipt, closeDay, and more.
Real device certificates
Register with a CSR and receive X.509 certs from the Mutero Sandbox CA — close to live ZIMRA FDMS Online flows.
Credential console
Generate device IDs and activation keys, open fiscal days, and exercise Online FDMS flows without a paid subscription.
OpenAPI + error catalog
Explore Online endpoints, RCPT/DEV/FISC rejects, and mTLS header alternatives for serverless clients.
