The short answer
Stock and invoicing are the same event seen from two sides: something left the shelf and something was sold. Where the two records disagree, one of them is wrong and it is worth knowing which.
The other system
Our reading, not a rule. Nothing below is a statement of what KRA requires.
A stock system tracks what came in, what went out and what should still be there. In trades carrying thousands of lines at different speeds, it is the only thing standing between the business and losses it cannot see.
Why a business joins them
Our reading, not a rule. Nothing below is a statement of what KRA requires.
Because a sale that moves stock without producing a document, or a document without moving stock, is the signature of both an error and a loss. Joining them turns a discrepancy from something you discover at stock-take into something visible the same week.
What would move, and which way
Our reading, not a rule. Nothing below is a statement of what KRA requires.
- Out: the item, the quantity and the line that moved, which is what makes the invoice and the shelf agree
- In: purchases, so the two sides of the stock equation come from the same place
- Returns and write-offs, which are where the disagreements usually start
Settle these first
Our reading, not a rule. Nothing below is a statement of what KRA requires.
- Whether stock is counted by line or by value. Only the first tells you where a loss is.
- Short-dated lines sitting next to slow ones, which is most of Kenyan retail and where expiry losses hide
- Who is allowed to adjust stock without a document, and whether that is logged
- Whether a sale can complete when the item is not in the system, and what the system does with it afterwards
What this does not solve
Our reading, not a rule. Nothing below is a statement of what KRA requires.
- Nothing here prevents shrinkage. It makes shrinkage measurable, which is a different and more useful thing.
- A stock system does not know about tax treatment. That still lives in the price list.
The question to ask a vendor. Ask what happens when a sale is made for an item that is not in the system, because it happens daily and the answer tells you whether the stock record will survive contact with the counter.
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.
