Basics
Getting started
Install Omnix, activate your licence, complete the setup wizard, and ring your first sale.
Welcome to Omnix — the offline-first POS and business software for Kenyan businesses. This guide takes you from download to your first sale in about ten minutes.
Download and install
Get the latest installer from omnix.co.ke/downloads. Run the .exe. If Windows shows a SmartScreen warning ("Windows protected your PC"), click More info → Run anyway — the installer is verified by a SHA-256 hash shown on the downloads page.
Omnix installs per-user (no admin rights needed) and takes about 30 seconds.
Activate your licence
On first launch you'll see the activation screen. If you've already bought a licence, paste the licence key — it binds to this machine and you're ready to go.
Haven't bought yet? Click Buy now right on the activation screen — it opens the checkout in your browser, you pay once (KES 30,000, one-time, no subscription), and the key arrives by email. Paste it back into Omnix to activate.
Complete the setup wizard
The wizard collects:
1. Your trade — tailors the app to your business. 2. Business details — name, address, phone, KRA PIN. These print on receipts and eTIMS invoices. 3. Owner account — your sign-in. Only the owner can reset other users' passwords or change billing.
Ring your first sale
Open POS, search a product (or scan its barcode — Omnix detects USB scanners automatically), add it to the cart, and hit Pay. Choose cash, M-Pesa, or card. Done — your first sale is recorded, stock is decremented, and (if eTIMS is configured) a KRA invoice is auto-signed.
