Belize Tax Service · Electronic Tax Documents

Enforcement begins in 2027.
There's a clock over every business that invoices.

When the Belize Tax Service requirement for Electronic Tax Documents takes effect, an invoice is no longer something you print — it has to be issued in an exact format, signed to a government-defined policy, and filed electronically. Get any part of it wrong and the document is rejected.

01 A strict XML format

UBL 2.1 with Belize's national EFDR profile — not a PDF, not a spreadsheet.

02 A real digital signature

An enveloped XAdES-EPES signature tied to your certificate and the BTS signature policy.

03 Submission to BTS

Sent to the VERTX-BZ platform over an authenticated, encrypted connection.

None of this is optional, and none of it is something you should have to build.
If you run Odoo, it is already handled.
If you don't, the same work happens behind one API call.

Where things stand

1 January 2025 GST (Amendment) Act 2024 in force

10 March 2026 Budget commits to e-invoicing

You are here September 2026 BTS publishes e-invoicing FAQs

2027 Enforcement begins, large taxpayers first

The technical specifications, registration procedures, accreditation requirements and exact mandatory implementation dates will be published by the Belize Tax Service.

If you are registered for GST — annual sales above $BZD 75,000 — this applies to you.
The standard GST rate does not change.
What changes is how the document carrying it is built, signed, and authorized before it reaches your customer.

Get ahead of the deadline

The product

Sign and files your tax documents - automatically.

Install the two apps, connect your ClearSign key, and carry on working the way you already do. Invoices, debit notes, credit notes and tax receipts from Sales.

Two apps: Sales & Point of Sale

Customer invoices, debit notes and credit notes from Sales; tax receipts issued as you close each order at the register. Install both if you sell at a till.

Sell through an outage

A failed sign never blocks a sale. Receipts queue at the register and a worker signs them automatically every few minutes, with duplicate-submission protection.

Contingency mode

Keep issuing when BTS is unreachable. The window is logged, the documents are marked accordingly, and they regularize automatically once the platform is back — reusing the identical document identifier, so nothing is duplicated.

Compliant printed output

Invoice PDFs carry the full BTS Graphic Representation — QR code, document identifier, authorization protocol — and POS receipts print the QR and identifier at the register.

Supplier invoices, answered

Photograph the QR on a supplier's invoice, pull the document from BTS, then accept it, annotate it, request a correction, or refuse it — each response filed as an event against the original.

One key per register

Each POS register carries its own ClearSign key, so every till issues on its own BTS series — and contingency can be switched on for one register without touching the others.

The API

Not on Odoo? Same engine, direct.

The Odoo apps are a client of a REST API you can call yourself. One request builds the document, signs it, and files it with BTS — every document type, plus cancellations and the responses you file against documents you receive. Separate sandbox and production keys, document sequencing handled server-side, an OpenAPI spec, and a full audit trail.

For growing businesses

Most businesses need more than a plug-in.

Signing credits get you compliant. The real work is connecting compliance to how your business actually runs — your systems, your data, your workflows. That's an integration project, and it's where ClearCommerce and ClearSign become the team you talk to.

Self-serve Credits & API

The Odoo apps or a direct API key, running on prepaid credits. One credit per document you file — invoices, receipts, debit and credit notes, and the events you file against them. The credits never expire.

Where the value is Integration project

We connect ClearSign to your ERP, point of sale, ecommerce and back office. Discovery, build, testing against BTS until every one of your document types comes back authorized, then cutover with us on the line through the first day of live filing.

Scoped and quoted after discovery

Ongoing After go-live

Changes, questions and help, sold as service hours scoped to your setup rather than a standing plan. BTS still has specifications to publish; when they land, somebody has to read them and make your integration match.
