The verdict in three sentences
A rechargeable prepaid balance turns ten small payments into a single top-up, which cuts per-transaction fees by 50 to 70 % and locks the customer into your brand. Purchase frequency climbs 1.8× and the average basket 20 %, especially with a 5 to 10 % top-up bonus. The real risk is financial: that balance is a float to provision, not earned revenue.
Wallet, subscription or points card?
Three mechanics drive loyalty, but they don't tie up the same cash or engagement. The stored wallet prepays consumption; the subscription bills access in advance; the points card rewards after the fact with no cash upfront.
| Mechanic | Cash tied up | Frequency effect | Fees avoided |
|---|---|---|---|
| Prepaid wallet (stored value) | High (customer float) | 1.8× | 50-70 % |
| Subscription | Medium (monthly) | 1.5× | Variable |
| Points card | None | 1.2× | 0 % |
The wallet wins when customers buy small amounts often: coffee, meals, data top-ups, everyday goods. Each individual micro-payment carries fixed fees; bundling them into one top-up melts the cost away.
The arithmetic of a top-up
The 2026 figures below are order-of-magnitude estimates for a high-frequency retail business in Kampala. They show the fee saving and the bonus's effect on re-loading.
| Indicator | 2026 order of magnitude |
|---|---|
| Fee saving (bundled top-up) | 50-70 % |
| Example | 1 top-up of UGX 55,000 vs 10 payments |
| Top-up bonus | +5 to +10 % |
| Purchase frequency lift | 1.8× |
| Average basket | +20 % |
| Re-load rate | 55-65 % |
| Float to provision | 100 % of unspent balance |
Across 10 payments of UGX 5,500, if each transaction carries UGX 110 of fixed fees, the customer (or you) pays UGX 1,100. A single UGX 55,000 top-up pays those fees once, a saving of around 60 %.

Mini case study
Aminata runs a fast-food spot popular with students in Kampala. Average basket: UGX 7,000, 4 visits/month per regular. She launches a prepaid wallet with a +8 % bonus on any UGX 55,000 top-up.
A student tops up UGX 55,000 and gets UGX 59,400 of balance. Convenience and bonus bring them back: visits rise from 4 to 7 per month (1.75×), average basket lifted to UGX 8,400. Over the month they spend UGX 58,800 instead of UGX 28,000. Aminata has tied up a float, but revenue per customer doubles and her re-load rate settles at 60 %.
FAQ
Does the prepaid balance belong to me? No, it's a float: customer money to be consumed, provisioned at 100 %. Spending it like revenue exposes you if many customers ask for a refund at once.
Is the top-up bonus profitable? Yes, if it triggers extra visits. An 8 % bonus costs UGX 4,400 on 55,000, easily offset by 1.8× frequency and a 20 % bigger basket.
What about dormant balances? Set clear rules: expiry, partial refund or re-engagement. A 55-65 % re-load rate means a third of customers leave a residual to handle cleanly.
Wallet or subscription — which to choose? The wallet suits frequent small purchases; the subscription suits predictable regular access. The wallet avoids 50-70 % of fees when tickets are small and numerous.
