Mobile Money Refunds: Process, Timelines and Partial Refunds (Nairobi 2026)

The verdict in three sentences

A clean refund is a retention tool, not a dead loss: refunding within 48h prevents ~60% of disputes and protects reputation. Three paths exist — the aggregator API (fastest), a manual wallet transfer, and a credit/voucher (which protects cash flow). The original debit fees (1-2%) are usually not recoverable, which is why partial refunds with a restocking fee make sense.

Three ways to refund, compared

Each method has a different cost and timeline. The right choice depends on your PSP and cash position.

The API is ideal if your PSP offers it; manual transfer remains the universal fallback; a credit keeps money with you but doesn't fit every case (unhappy customer, defective product).

Timelines and fees by PSP: 2026 order of magnitude

Here's a 2026 estimate of refund capabilities across major players (confirm in your contract).

Golden rule: on a physical product, apply a restocking fee of 5 to 15% on non-defective returns, to cover non-recoverable fees and logistics.

Mini case study

Grace runs an appliance shop in Nairobi. A customer cancels an order of 80,000 KES paid via M-Pesa, initial fees 1.5% (1,200 KES non-recoverable). Non-defective return: she applies a 10% restocking fee, 8,000 KES. She refunds 72,000 KES within 48h. Real cost to her: the 1,200 KES initial fee, well covered by the restocking fee. Result: the customer stays satisfied, no dispute opened, and her cash isn't dented. Across 12 refunds/month handled this way, she avoids several disputes that would have cost time and negative reviews.

FAQ

How fast does the customer get their money? Via a manual M-Pesa/MoMo wallet transfer, expect 24-72h; via an API refund (Flutterwave, Paystack), it's T+0 to T+2. Always tell the customer the timeline to avoid worry.

Do I recover the original payment fees? Rarely in full. The original debit fees (1-2%) often stay on you, which justifies a partial refund on non-defective returns.

Is a partial refund legal and accepted? Yes, if disclosed upfront in your terms: restocking fee 5-15% on non-defective returns. For a defective product, refund in full.

Does refunding fast really help? Yes: a refund within 48h prevents about 60% of disputes and negative reviews. Speed is your best reputation insurance.

Is a voucher better than a refund? A voucher protects cash flow and suits change-of-mind cases, but impose it only when justified: for a defective product, a cash refund remains the norm.
