What makes a promotion work
A sales promotion is a temporary offer designed to change customer behaviour: to buy now, buy more, try something new, or come back. The key word is temporary and purposeful, a promotion should have a specific goal and an end, not become a permanent discount that erodes your margin and trains customers to wait.
Promotions can serve different goals: clearing slow or aging stock, lifting a predictably quiet period, rewarding loyal customers, or introducing a new product. The design should match the goal, a clearance discount for old stock is different from a loyalty reward for regulars.
The difference between a profitable promotion and a costly one is margin and measurement. You must design the offer so you still make money (or strategically accept a small loss for a clear gain), and you must measure afterwards whether it actually drove the result you wanted, so you repeat what works and drop what does not.
How to run a promotion, step by step
Goal, margin, promote, measure.
- 1
Step 1: Set a clear goal
Decide exactly what the promotion is for: clear slow stock, lift a quiet period, reward regulars, or launch a product. The goal shapes the offer.
- 2
Step 2: Design the offer to protect margin
Work out the numbers so you still make money, or knowingly accept a small loss for a clear strategic gain. Never discount blindly into a loss.

Step 3: Set a clear start and end
Give the promotion a defined period. A deadline creates urgency, and an end stops it becoming a permanent discount.

Step 4: Promote it where customers are
Tell customers through WhatsApp, at the counter, and in local groups. An unpromoted offer does nothing.

Step 5: Track it as it runs
Watch sales during the promotion to see if it is working, so you can react, extend a winner or end a flop early.

Step 6: Measure whether it paid off
Afterwards, compare sales and profit to a normal period. Did it actually drive profitable sales or just give away margin? Use the answer next time.
Promotion mistakes
No clear goal
A promotion without a specific purpose is hard to design or judge. Decide what it is for first.
Discounting into a loss
Cutting prices without checking the margin can mean selling more while earning less. Design the offer to protect profit.
No end date
A promotion with no end becomes a permanent discount that erodes margin and trains customers to wait. Set a clear deadline.
Not promoting it
An offer customers do not know about cannot work. Promote it where your customers actually are.
Never measuring
Without measuring, you cannot tell if the promotion paid off or just cost you margin. Always check the result.
A shop runs a promotion that pays off
A shop in Nairobi used to run vague discounts that felt busy but never seemed to help, and may have been losing money.
For its next promotion, the owner set a clear goal (clear aging stock), designed the discount so it still covered cost, gave it a one-week deadline, promoted it on WhatsApp and at the counter, and tracked sales.
Afterwards she compared the week to a normal one: the old stock cleared, overall sales rose, and margin held. A deliberate, measured promotion worked where the old vague discounts never had.
When M-Pesa payments are not matched to sales, a missing payment, a staff shortfall or a double charge can slip past you until the money is already gone.
Veira reconciles M-Pesa Till and Paybill against every sale, so a mismatch surfaces the same day instead of at month end.
How Veira makes promotions pay
Veira shows your sales and margins before, during and after a promotion, so you can design offers that protect profit and measure whether each promotion actually paid off. You see if it lifted sales, cleared the stock, or just gave away margin.
With that data, promotions become a deliberate tool rather than a gamble: you repeat what works, drop what does not, and grow profitable sales, all from your phone, from KES 2,999 a month.
