KRA eTIMS setup

Omnix has KRA eTIMS built in — no third-party middleware. Every sale can be auto-signed and submitted.

Before you start

You'll need your KRA PIN and your eTIMS credentials (the device serial + CU details KRA issued you). Have your business KRA PIN handy.

Configure eTIMS

Open Settings → eTIMS. Enter your KRA PIN, the eTIMS environment (sandbox for testing, production for live), and your device credentials. Save and run Test connection — Omnix sends a test invoice and confirms KRA accepted it.

How signing works

Once configured, every completed sale is queued for signing. Omnix submits the invoice, KRA returns a signature + QR code, and that prints on the customer's receipt. If you're offline, invoices queue and sign automatically when the connection returns.

The eTIMS queue

Reports → eTIMS shows the queue: signed, pending, and any failures. Failed invoices retry automatically; you can also retry manually or inspect the KRA error.

VAT3 return

At month-end, Omnix generates your VAT3 return from the signed invoices — output VAT, input VAT, and the net position — ready to file.
