Business Advice · Tax Compliance
Your clients are keeping a list of who can give them a fiscal invoice. Make sure your name is on it.
From 2026, VAT-registered businesses in Zimbabwe are actively choosing suppliers who issue fiscalised invoices — because it is the only way they can claim their input tax back. Here is what fiscalisation means, why it matters for your revenue, and exactly how to get set up.
Picture this: a procurement manager at a well-run company is comparing two suppliers. The products are similar. The prices are close. One supplier hands over a fiscalised tax invoice with a QR code that validates on the ZIMRA portal. The other gives a Word document with a logo. The procurement manager chooses the first supplier every time — not out of preference, but because their finance team needs that QR code to claim back input VAT on their next return.
This is the quiet shift happening across Zimbabwean business right now. Fiscalisation has gone from a compliance box to a commercial differentiator. The businesses that understood this early are already winning the contracts. The ones that have not yet registered are losing sales they do not even know they lost.
What fiscalisation actually is
Fiscalisation is ZIMRA's system for recording every taxable sale at source. Under the Fiscalisation Data Management System (FDMS), every VAT-registered operator must issue invoices through an approved fiscal device — hardware or virtual — that reports the transaction directly to ZIMRA in real time.
The result is a Fiscal Tax Invoice with a QR code that any customer, auditor, or ZIMRA official can scan and validate at fdms.zimra.co.zw. If the QR code validates, the invoice is real and the input tax claim holds. If it does not, the claim fails.
Why your B2B customers need your fiscal invoice
Input tax recovery
VAT-registered businesses can offset the VAT they paid on purchases against the VAT they collected on sales. Without a valid fiscal invoice, the input tax claim is disallowed — so they pay more tax than they should.
Audit defence
During a ZIMRA audit, every input tax claim must be supported by a valid fiscal invoice. A non-fiscal supplier invoice exposes the buyer to reassessment and penalties.
Procurement policy
Many larger companies and NGOs now require fiscal invoices as a condition of payment. Without one, your invoice goes to the bottom of the pile — or gets rejected entirely.
Hardware device or virtual device — which one is right for you?
ZIMRA gives you two routes to compliance. The right one depends on how your business operates.
Option A — Hardware fiscal device
A physical device installed at your point of sale, supplied by a ZIMRA-approved hardware vendor. The supplier tests and registers it with FDMS on your behalf.
Best for
Retail shops, restaurants, and businesses with a fixed till that process high transaction volumes in person.
Option B — Virtual fiscal device (API)
A software integration between your invoicing or accounting system and the FDMS API. No physical hardware. Works from any device, anywhere.
Best for
Service businesses, consultants, wholesalers, and any business that invoices clients rather than running a physical till. This is how Marii connects.
How Marii keeps you on top of your tax
Tax compliance is only a burden when your records are scattered. Every invoice you raise on Marii is stored, dated, and linked to the customer who received it. When tax season arrives, the numbers are already organised.
Fiscalised tax invoices
Once your FDMS registration is active, every invoice you raise through Marii carries the required QR code and fiscal reference — ready for your customer to claim input tax.
QPD preparation
Your Quarterly Payment Dates require you to estimate your VAT liability for the period. Marii's sales records give you a clear, exportable view of your output tax — so the QPD calculation takes minutes, not hours.
VAT7 return support
Your VAT7 return requires a total of all taxable sales, exempt sales, and input tax claimed for the period. Marii keeps this data organised by date, customer, and tax category — exactly the structure your accountant needs.
Verifiable invoice trail
Every fiscal invoice has a QR code that validates on the ZIMRA FDMS portal. Your customers can verify invoices instantly, and your records are audit-ready at all times.
Fiscalisation is a Pro feature
FDMS-connected fiscalised invoicing is available on Marii Pro plans, starting at $7 per month or $60 per year. The annual plan works out to $5 per month — less than a cup of coffee, and fully deductible as a business expense.How to get your online fiscal device — step by step
For the virtual (API) route — which applies to most Marii merchants — here is what the ZIMRA onboarding process looks like from start to finish.
Option B — Virtual Fiscal Device registration
Download the API documentation
Download the FDMS API document from the ZIMRA website. This covers the technical specification for connecting your software to the FDMS platform.
Contact ZIMRA to request test environment access
Email the three ZIMRA FDMS contacts below to request registration in the test environment and to receive the API endpoint details.
Test your integration
Use the FDMS test platform to generate sample Fiscal Tax Invoices, Credit Notes, and Debit Notes. Close a fiscal day and confirm there are no errors.
Submit samples to ZIMRA for approval
Send your sample documents — Fiscal Tax Invoice, Credit Note, Debit Note — to ZIMRA for review and approval.
Go live
Once ZIMRA approves your samples, your device is registered in the FDMS live environment. You can start issuing fiscalised invoices immediately.
ZIMRA FDMS contacts — email all three
In your email, introduce your business, state that you are applying for virtual fiscal device registration under Option B, and ask for the test environment details and API endpoint configuration.
Connecting your fiscal device to Marii
Once ZIMRA has registered you in the live FDMS environment, you will have three credentials: a Device ID, Serial Number, and Activation Key. These come from the ZIMRA TaRMS Self-Service Portal — log in, navigate to Fiscalisation → Add Virtual Device, and they are generated for you there.
Bring those three values into Marii and the rest is automatic.
Marii dashboard → Settings → Billing & Tax
Open ZIMRA Fiscalisation in Marii Settings
Go to your Marii dashboard, navigate to Settings → Billing & Tax. You will see the ZIMRA Fiscalisation card (Pro plan only).
Enter your three ZIMRA credentials
Paste in your Device ID (a number, e.g. 33250), Serial No. (e.g. MARII-01), and your Activation Key (8 characters, from TaRMS).
Click "Save ZIMRA Config"
Marii registers the device against your tenant, securely encrypts the Activation Key, and connects to the FDMS portal. The card will show an Active badge once registration succeeds.
Confirm your device status
After saving, two live indicators appear on the card: a Device QR link that opens your device record on the ZIMRA FDMS portal, and a Certificate valid until date with a countdown chip so you know when the certificate needs renewal. Both pull directly from ZIMRA — if they are visible, your device is connected.
Use Resync if you need to refresh
The Resync with ZIMRA button re-pulls the latest device status, QR URL, and certificate expiry from the FDMS portal on demand. Use it if the portal status changes or after a certificate renewal.
Fiscalisation menu missing in TaRMS?
If you log into the ZIMRA TaRMS Self-Service Portal and the Fiscalisation menu is not visible, your account is likely registered for Income Tax only. Email fiscalisation@zimra.co.zw to request the Virtual Fiscal Device module be activated on your TaRMS profile.Pro plan · from $7/month or $60/year
