The True Cost of Mobile Money Collections in Kenya (2026 Breakdown)

The verdict in three sentences

In Kenya, the true cost of collecting a mobile money payment is not just the M-Pesa fee: you must add the API/Daraja cost, the manual reconciliation time and the cost of failed payments. A key lever is the Till (Buy Goods) vs Paybill difference — Till is often effectively free to the merchant while Paybill carries a percentage (~0.55% order of magnitude 2026). This model gives you the cost per transaction and the real net margin across three volume levels.

Cost per transaction, line by line

Values are 2026 estimates for a KES 1 500 average basket. Adjust to your tariff.

Manual reconciliation is the forgotten line: at 45 seconds per op and 300 ops/month, that is 3.75 hours/month of unbillable work.

Net margin across 3 volumes (KES 1 500 basket)

As volume rises, fixed costs (API, dashboard) dilute and the effective rate edges down — the case for automating early: the more you collect, the more automation pays for itself.

The cost of failed payments

A failed payment isn't neutral: it triggers a retry and sometimes a lost basket. If 3% of 300 transactions fail, that is 9 baskets/month at KES 1 500, i.e. KES 13 500 of revenue at risk. Halving that failure rate with a robust checkout (auto-retry, managed timeout via Daraja STK Push) recovers margin directly.

Mini case study

Wanjiru, who runs an online grocery in Nairobi, handles 300 orders/month at KES 1 500 (KES 450 000). On Paybill at ~0.55% she pays about KES 2 475. She also spends ~4 hours/month reconciling manually (internal cost ~KES 2 000) and loses ~2% of orders to failures (~KES 13 500 revenue). By switching to Till where suitable, automating reconciliation and adding retry, she recovers the hours and halves failures: ~KES 9 000/month of value regained, over KES 100 000/year.

FAQ

What's the difference between commission and true collection cost?

Commission is the wallet's cut. True cost adds Daraja API, manual reconciliation and failed payments, which can add 30-50% on top — even when Till itself is near-free to the merchant.

Till or Paybill for my business?

Till (Buy Goods) is often effectively free to the merchant, while Paybill carries ~0.55%. Choose Till for simple retail collections; Paybill when you need account references and structured reconciliation.

Is the Daraja API worth it?

Yes as volume grows: STK Push plus webhooks removes manual entry and makes accounting reliable. The fixed cost dilutes and the effective rate drops with volume.

How do I reduce failed payments?

A checkout with STK Push retry, timeout handling and clear messaging can halve the failure rate. On 300 orders that can mean tens of thousands of KES recovered monthly.

How do I cost manual reconciliation?

Multiply time per op (30-60 s) by monthly volume, then by your internal hourly cost. At 300 ops, expect ~3-4 hours/month, usually invisible in the budget.
