Tiiso
Lesotho development preview. Mock demonstrations only; not RSL-accredited.

For VAT-registered businesses

From your invoice to its QR code.

Tiiso connects your accounting system to your country’s tax e-invoicing system.

Lesotho is our first development target, for RSL Lekuka. Other countries are planned, not available yet.

About this development preview

This is not participation in RSL’s taxpayer pilot. Current demonstrations use a mock gateway, not authority acceptance.

The document’s return path

Sent isn’t done.

From the invoice you create to the answer you need.

Sending is not acceptance. The portal design separates submission results from slip and QR report readiness, so you can see what needs attention.

When the connection drops

A place for documents to wait.

The planned Evolution connection keeps captured documents on your computer while offline. When the connection returns, signing and submission resume in order.

RSL’s guide covers offline batches, but our capture queue does not issue offline fiscal invoices. Confirm the authorised mode and timing with RSL before trading during an outage.

No answer is not a refusal. If a submission’s result is unknown, pause the device and check its status before sending again.
