The short answer
both are a lightweight channel for businesses issuing few invoices, and they differ in the invoicing rhythm they assume. The choice follows from how your business issues invoices: how many, how fast, and whether the connection holds while you do it.
Side by side
| eTIMS Lite | eTIMS Lite on USSD | |
|---|---|---|
| Kind of thing | A simplified channel reached through eCitizen, with USSD and mobile routes alongside it. | A USSD menu dialled from any mobile phone, working over the mobile network rather than over data. |
| Runs on | a smartphone, a laptop, a desktop, a basic phone | a basic phone, a smartphone |
| Connection | Depends on setup | Mobile network, not data |
| Invoice rhythm | Occasional, a few invoices | Occasional, a few invoices |
eTIMS Lite
The lighter route, which KRA makes reachable through eCitizen as well as through USSD and a mobile solution. Aimed at businesses issuing few invoices rather than at a busy till. Occasional invoices, raised one at a time, usually because a specific customer asked. Not a till system and not intended as one.
eTIMS Lite on USSD
The USSD route into eTIMS Lite: a shortcode dialled from a phone, with no app and no smartphone required. Single, short invoices. The format itself sets the ceiling: what fits through a USSD menu is what you can issue.
How to choose between them
Our reading, not a rule. Nothing below is a statement of what KRA requires.
eTIMS Lite gets awkward when
Any volume at all: it is built for few invoices, not many. A business that needs invoicing joined up with stock, because it is not a POS. A trade where the invoice has many lines on it.
eTIMS Lite on USSD gets awkward when
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.
KRA states that eTIMS applies across business structures and sectors, including businesses that are not registered for VAT. Whether a particular business is in scope still depends on its own circumstances, which is a question for KRA.

Common questions
Which is better, eTIMS Lite or eTIMS Lite on USSD?
Neither, as a general matter. They assume different invoicing patterns, and the one that suits a business follows from how many invoices it issues and how reliable its connection is.
When would eTIMS Lite be the wrong choice?
Any volume at all: it is built for few invoices, not many.
