The short answer
Margin is only knowable if cost includes transport and what was lost getting goods onto the shelf, because margin against the buying price alone flatters every line in the shop. For mobile phone shops specifically, that plays out against how the trade already sells and to whom.
Pricing and margin for mobile phone shops
Handsets are serialised and depreciate quickly, while accessories are low value and easily lost, so the same shop has to control two opposite kinds of inventory at once. That is the background against which pricing and margin has to work in this trade.
What invoicing actually looks like here
Business customers buying handsets for staff expect an invoice with the company PIN. Repairs and accessories stay receipt-level, so the shop needs to handle both without treating every sale as a formal invoice.
What the rules say
This page explains how a requirement generally works. It is not tax advice, and it cannot account for the specifics of any one business. For a position you intend to rely on, confirm with KRA directly or with a registered tax agent.
Tax rules in Kenya change with each Finance Act and with regulations made during the year. Before acting on any figure, deadline or threshold, check the current position on KRA's own website.
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.
Knowing the margin requires knowing the cost
A surprising number of businesses can state their selling price precisely and their true cost only approximately, because cost means the buying price plus transport plus whatever was lost or damaged getting it onto the shelf. Margin computed against the buying price alone flatters every line in the shop.
Wholesale price changes are the silent problem
When a wholesaler raises a price and the shop does not notice, the margin on that line goes down and nothing announces it. Retailers discover this at the end of a month that felt busy and was not profitable. Checking buying prices against selling prices on the fast-moving lines, regularly, catches it.
Where this goes wrong
- Handset models losing value on the shelf
- Accessories walking out untracked
- Agency float mixed with shop money
Common questions
Does a mobile phone shop need to issue a tax invoice for every sale?
Business customers buying handsets for staff expect an invoice with the company PIN. Repairs and accessories stay receipt-level, so the shop needs to handle both without treating every sale as a formal invoice.
What usually goes wrong with records in a mobile phone shop?
The recurring problems in this trade are handset models losing value on the shelf; accessories walking out untracked; agency float mixed with shop money; repairs taken in without a record of the device. Each of them shows up in the records before it shows up in the bank balance.
How should a mobile phone shop keep stock records?
Handsets are serialised and depreciate quickly, while accessories are low value and easily lost, so the same shop has to control two opposite kinds of inventory at once. Records that do not reflect that pattern will not tell you anything useful, whatever system produces them.
