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 juice bars specifically, that plays out against how the trade already sells and to whom.
Pricing and margin for juice bars
Fruit that must be bought, used and written off within days, where a wet week or a bad delivery turns directly into loss and there is no way to hold stock through a slow period. That is the background against which pricing and margin has to work in this trade.
What invoicing actually looks like here
Pure receipt trade in normal operation, with invoices appearing only for event and office supply orders.
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
- Fruit spoilage with no salvage value
- Recipe consistency between staff
- Fruit price volatility by season
Common questions
Does a juice bar need to issue a tax invoice for every sale?
Pure receipt trade in normal operation, with invoices appearing only for event and office supply orders.
What usually goes wrong with records in a juice bar?
The recurring problems in this trade are fruit spoilage with no salvage value; recipe consistency between staff; fruit price volatility by season; cash trade with no record of what sold. Each of them shows up in the records before it shows up in the bank balance.
How should a juice bar keep stock records?
Fruit that must be bought, used and written off within days, where a wet week or a bad delivery turns directly into loss and there is no way to hold stock through a slow period. Records that do not reflect that pattern will not tell you anything useful, whatever system produces them.
