Why the Gateway

Everything you need to fiscalise — nothing you don't

The gateway owns the VSDC and handles the ZRA keys, so your systems simply post sales details and receive verifiable receipts in milliseconds.

Drop-in fiscalisation API

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

We run the VSDC

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

Multi-tenant by design

Partner → Tenant (TPIN) → Branch → API key. Every credential is securely hashed, scoped, and every merchant sees only their own data.

Signed invoices + QR

Each invoice contains the SDC signature, internal tax metrics, and a dynamic receipt validation QR link for a fully compliant invoice.

Two API surfaces

A modern JSON `/api/v1` using clean scopes, and a legacy `/zm/api` compatibility surface for seamless drop-in migrations.

Live monitoring

An operator console plus per-merchant dashboards: tracking invoice throughput, VSDC status, logs and debugging diagnostics.

Seamless Integration

From sale to official invoice in three steps

The gateway acts as an intelligent intermediary between your business systems and the Zambia Revenue Authority.

Register the device

A quick one-time configuration maps your business details with ZRA, retrieving security keys and active document counter indexes.

Send the sale

Submit items and customer details. The gateway calculates the VAT (16%), constructs the signed payload, and sends it to the VSDC.

Get the official number

Read the response containing the receipt number (`rcptNo`). The gateway stores the details and provides a verified QR tax invoice receipt.

Developer Centric

Fiscalise a sale with a single request

Bearer-authenticate as a tenant, post the sale payload, and receive verified receipt data back immediately.
