Zimbabwe FDMS Invoice
ZIMRA Fiscalisation Data Management System for Odoo 18 & 19
Fiscalise your Zimbabwean customer invoices and credit notes directly from Odoo against the Zimbabwe Revenue Authority (ZIMRA) Fiscalisation Data Management System (FDMS) via the Fiscal Device Gateway API. JSON receipts, mandatory buyer detail, BPN validation and the verification QR — all built on the shared e-Invoice Core Engine.
FDMS Receipt Builder
Every posted invoice and credit note is converted to the ZIMRA
submitReceipt JSON structure: receipt lines, the A/B/C tax-code
breakdown, payments and decimal totals, with the canonical, signable
serialization and the device-signature hash required by ZIMRA.
Mandatory Buyer Detail
The FDMS buyerData block is populated with the buyer's registered
name, BPN/TIN, VAT number, address and contacts — enforcing the buyer-detail
transmission rule in force since 31 May 2025 so your customers can claim input tax.
Real BPN Validation
ZIMRA Business Partner Numbers are validated with the genuine mod-11
check-digit algorithm (9 digits + check character, X for remainder 10)
on company and partner records and in the onboarding wizard. VAT registration
numbers are validated structurally.
Signature Chain & QR
The receipt device-signature hash is computed with SHA-256 and chained to the previous receipt, and the ZIMRA verification QR (receipt-verification URL with the 16-character QR data) is rendered to a scannable PNG on the invoice.
Fiscal Device Gateway Client
GetConfig, GetStatus, OpenDay, SubmitReceipt and CloseDay over a resilient REST transport with retry/backoff, documented sandbox and production endpoints as editable defaults, and device-certificate (mutual-TLS) authentication. Fiscal day, receipt counter and global number are managed per device, with full transport logging.
Bring Your Own Keys
Your ZIMRA device certificate and private key stay in your database and are used only to authenticate to the gateway and seal receipts locally. Nothing is bundled and no credentials ever leave your system.

Disclosure
This module is an invoice-format generator and a bring-your-own-key transport — it is not an MRA/ZIMRA-accredited service operator. It transmits invoice data only to the ZIMRA FDMS Fiscal Device Gateway endpoint you configure, using your own ZIMRA-registered device. Your device certificate and private key are bring-your-own-key, never bundled, and never leave your database except to authenticate to the gateway you set. No data is sent anywhere else. Requires the e-Invoice Core Engine. Compatible with Odoo 18 and 19.
Currency & rate: Zimbabwe operates a multi-currency regime — receipts carry their ISO 4217 currency (ZWG, Zimbabwe Gold, and USD predominate). The applicable tax rate is driven by the device GetConfig configuration, not hard-coded; Zimbabwe's standard VAT rate rose from 15% to 15.5% effective 1 January 2026 (ZIMRA Public Notice 07 of 2026), which the per-line rate handling absorbs automatically.
