WHY

Why we built it.

We believe every vendor deserves the tools of a big company. A stall, a duka or a pharmacy keeps a community running. It should never run blind.

◔

Cash goes missing

Paper books and memory lose money quietly, one sale at a time.

▤

Stock runs out

You find out when a customer is already standing at the counter.

§

Tax feels heavy

eTIMS should be a habit you keep, not a fear you carry.

WHY, WHAT, HOW IN MOTION

See it in motion.

The Omnistack film. Watch the problem, then the fix.

WHAT

What you get.

One system to sell, count and report. Everything a Kenyan business needs, in one place.

◎

Cash and M-Pesa

Take both at the same till. Every payment lands in the right place.

▥

Live stock

Every sale updates your shelves. See what is low before it is gone.

✓

eTIMS ready

Stay on top of tax with receipts and records that follow the rules.

↗

Reports that make sense

Daily sales, best sellers and profit, without a spreadsheet.

☺

Your team, your rules

Give each person the access they need and nothing more.

▭

Any device

Use it on a phone, tablet or computer. Open it and sell.
