The short answer
eTIMS Lite on USSD is named as a fit for general shops because of the invoicing pattern the trade has, not because of what it sells.
eTIMS Lite on USSD in general shops
Our reading, not a rule. Nothing below is a statement of what KRA requires.
eTIMS Lite on USSD is named here as a fit for general shops because of how the trade issues invoices, not because of what it sells. A USSD menu dialled from any mobile phone, working over the mobile network rather than over data. What decides whether it works in practice is the trade's own invoicing reality: Nearly every sale is a small cash or M-Pesa transaction to a walk-in customer. A duka that is not VAT-registered still faces the question when a nearby business or a landlord asks for a proper invoice, and when its own suppliers start issuing eTIMS invoices that must be kept for the shop's own records.
What invoicing actually looks like here
Nearly every sale is a small cash or M-Pesa transaction to a walk-in customer.

The invoicing pattern it assumes
Our reading, not a rule. Nothing below is a statement of what KRA requires.
Single, short invoices. The format itself sets the ceiling: what fits through a USSD menu is what you can issue.
Where it gets awkward
Our reading, not a rule. Nothing below is a statement of what KRA requires.
- Invoices with more than a couple of lines, because a USSD session is a small window
- Anything you need a copy of on a screen afterwards
- A session that times out halfway, which is the normal frustration of the format
What the rules say
Stated by the publisher from the cited KRA material. Our reviewer has not yet re-checked it against the source, so confirm anything you are about to act on with KRA directly.
KRA identifies several categories of eTIMS solution, among them eTIMS Online, the eTIMS Client, eTIMS Lite, system-to-system integration, reverse invoicing and buyer-initiated invoicing. Which one suits a business depends on how it issues invoices rather than on what it sells.
KRA documents eTIMS Client options for Windows and for Android, and makes eTIMS Lite reachable through eCitizen, through USSD and as a mobile solution.

What we are not stating here. Some of the specific requirements relating to this topic have not yet been verified against their primary source by our reviewer, so they are withheld from this page rather than stated from memory. That means you will not find a threshold, rate, deadline or penalty figure below. For those, check KRA directly. Everything else on this page explains how the mechanism works and is not affected.
Common questions
Does a general shop need to issue a tax invoice for every sale?
Nearly every sale is a small cash or M-Pesa transaction to a walk-in customer. A duka that is not VAT-registered still faces the question when a nearby business or a landlord asks for a proper invoice, and when its own suppliers start issuing eTIMS invoices that must be kept for the shop's own records.
What usually goes wrong with records in a general shop?
The recurring problems in this trade are goods leaving on informal credit that is never written down; cash and m-pesa mixed with household money; not knowing real margin after wholesaler price changes; stockouts on the fastest lines. Each of them shows up in the records before it shows up in the bank balance.
How should a general shop keep stock records?
A few hundred fast-moving lines bought in small quantities from nearby wholesalers, often restocked several times a week, with unga and cooking oil turning fastest. Records that do not reflect that pattern will not tell you anything useful, whatever system produces them.
