Why the gateway

Everything you need to fiscalise — nothing you don't

The gateway owns the VSDC and the ZRA keys. Your systems post a sale and read back a verified receipt.

One call to fiscalise

POST a sale with its line items and customer; get back the official ZRA receipt number, signature and QR in one call.

We run the VSDC

The gateway hosts the device and holds the ZRA security keys. Your code never touches a device or a secret.

Multi-tenant by design

Partner, tenant (TPIN), branch, API key. Every credential is hashed and scoped; merchants see only their own data.

Signed invoices and QR

Each invoice carries the SDC signature, the internal tax metrics and a live receipt-verification QR link.

Two API surfaces

A modern JSON /api/v1 with clean scopes, plus a /zm/api compatibility surface that keeps a legacy till's request payload.

Offline-safe queueing

If the VSDC is unreachable the sale is still accepted, then uploaded in strict invoice order the moment it returns.

How it works

From sale to official invoice in three steps

Register the device

A one-time initialisation maps your business to ZRA, retrieves the security keys and syncs the document counters.

Send the sale

Post items and customer details. The gateway computes VAT, builds the signed payload and calls the VSDC.

Get the official number

Read the receipt number back, store it against your order, print the QR. The gateway keeps the audit trail.

For developers

Fiscalise a sale with a single request

Authenticate as a tenant, post the sale, read the verified receipt back from the same response. No polling, no device SDK.
