Setting cashier discount limits at the till
How a shop can stop cashiers giving discounts beyond what it allows, with a cashier limit, supervisor approval above it and house rules for the reasons.

Of everything a cashier does, discounting is one of the few things that costs the business money every single time. A regular gets something off, a scuffed box is marked down, a friend of a friend asks for "the staff price". By month end the margin is thinner than the price list promised, and nobody can say who gave what, or why.
Banning discounts is not the answer: a sensible markdown on damaged stock, or a gesture after a complaint, is good business. What a shop needs is a clear rule about who may give how much, a till that enforces it, and a habit of sending bigger discounts to someone else for a decision.
Here is how a shop in South Africa, Nigeria or Kenya can set that up with Achekam's till.
How margin slips away without anyone noticing
The common leaks are familiar:
- Friends-and-family discounts that nobody approved.
- Price matching on a customer's word, with no proof of the competitor's price.
- Damaged-stock markdowns given on stock that was not damaged.
- A whole-basket discount used to round a total down to a neat figure.
Very few of these are dishonest. Most come from cashiers trying to be helpful without a rule to follow. The cure is a rule the till enforces, so the cashier does not have to say no on their own.
Line discounts and whole-sale discounts
Achekam's till allows two kinds. A line discount applies to one item: the dented tin, the last one in a colour you are not reordering. A whole-sale discount applies to the entire basket: a trade arrangement, or goodwill after a complaint.
Line discounts are usually easier to justify afterwards, because the reason belongs to the item. Whole-sale discounts deserve more scrutiny, because they can quietly cover anything in the basket.
The cashier limit and the supervisor above it
The business sets a cashier limit. Below it, the cashier can give a discount without help. Above it, only a supervisor or manager can give the discount. A limit like this is one kind of internal control; ACCA's overview of internal controls explains the control environment, the main types of control and segregation of duties.
Choosing the limit takes judgment. Set it too low and supervisors are called to every till for routine markdowns, which slows the queue and teaches everyone to wave approvals through. Set it too high and it stops nothing. Start from what a cashier honestly needs for everyday markdowns, then look again after the first month of trading.
Why the server checks the discount a second time
Achekam checks the discount at the till and checks it again on the server. A sale carrying a discount above the cashier limit, without a supervisor or manager behind it, is not accepted.
The second check is what makes the limit real. A rule enforced only on the screen depends on the screen; a rule enforced on the server applies however the sale arrives, including sales held in the browser during a dropped connection and sent once it returns.
The server applies another rule that helps here: it refuses any till sale that is not paid in full. A discount cannot be used to leave part of a sale owing, so "pay the rest next time" is not something a cashier can ring up.
No PIN: the person signed in is the cashier
Achekam's till has no cashier PIN. The cashier is the user who is signed in. That has practical consequences:
- Every cashier needs their own login. A shared "till" login turns every discount into an anonymous one.
- A supervisor who signs in to approve a discount should sign out again before handing the till back.
- At a shift change, the outgoing cashier signs out and the incoming one signs in, even if the till stays open.
The same approach covers refunds, voids and cash paid out, which also need a supervisor or manager; see refunds, voids and store credit at the till and safe drops, cash paid out and banking the takings.
House rules for discount reasons
The till enforces the limit. Your house rules supply the judgment. A workable set looks like this:
- List the reasons that justify a discount in your shop, such as damaged goods, price match with proof, staff purchase or agreed trade terms.
- A supervisor approving a discount sees the item or the proof first.
- Staff purchases are approved by someone other than the buyer.
- Whole-basket discounts above the cashier limit are kept for complaints and trade arrangements.
- A manager looks over the week's discounted receipts and asks about anything unusual.
Write these down and put them where cashiers can see them. A cashier who can point to the house rules finds it much easier to tell a pushy customer that a bigger discount needs a supervisor.
Where discounts show in the books
Every till sale posts a balanced journal: the payment to its own account, revenue, output VAT, and cost of sales at the product's cost price. A discount lowers what is charged while the cost of the goods stays the same, so heavy discounting appears as a thinner gross margin. What a till sale posts to your books explains which accounts to watch.
If gross margin drops in a month when prices and suppliers did not change, discounting is one of the first places to look.
Decide the cashier limit, write the list of acceptable reasons, and give every cashier and supervisor their own login before the next trading day. Those three steps close most of the gaps that let margin drift away.
