The verdict in three sentences
The advertised aggregator rate is a starting price, not a final one. Above clear volume thresholds it becomes negotiable: in Nairobi the standard 2 % drops to 1.7 % above KES 5M/month, then 1.5 % higher up. Before signing, demand the written tiers, the contract lock-in, the chargeback reserve and a custom payout schedule.
Volume tiers are never advertised
Aggregators publish their entry rate but keep the tiers for the negotiation table. Knowing the grid before the sales call shifts the balance of power. Here are the tiers observed in Nairobi in 2026.
| Monthly volume | Nairobi rate | Douala rate (ref) |
|---|---|---|
| < KES 5M | 2.0 % | 2.5 % |
| KES 5M to 15M | 1.7 % | 1.9 % |
| KES 15M to 30M | 1.5 % | 1.6 % |
| > KES 30M | 1.3 % (quote) | 1.3 % (quote) |
2026 order of magnitude. If your volume is near a threshold, project your 6-month growth and negotiate the higher tier now, with an automatic review clause.
Levers beyond the rate
The percentage is only one of five levers. A good deal optimizes the whole set. Here is what to ask for explicitly in the call.
| Lever | Standard | To negotiate |
|---|---|---|
| Transaction rate | 2.0 % | volume tier 1.5 to 1.7 % |
| Contract lock-in | 24 months | 12 months or none |
| Chargeback reserve | 10 % held 90 d | 5 % held 30 d |
| Payout schedule | weekly | daily or T+1 |
| Setup fee | KES 15,000 | waived above KES 5M/month |

Mini case study
Grace, who runs a food chain in Nairobi, collects KES 4M/month. At the standard 2 %, she pays KES 80,000/month. By negotiating the tier at 1.7 %, she drops to KES 68,000/month, saving KES 12,000 per month, or KES 144,000/year. She also secures the chargeback reserve moving from 10 % to 5 % and a T+1 payout, freeing roughly KES 200,000 of locked cash flow.
FAQ
At what volume is negotiation worth it? From about KES 4 to 5M/month. Below that the leverage is weak; above it, every tenth of a point means hundreds of thousands per year.
What if I have not reached the threshold yet? Negotiate an automatic review clause: once you exceed the tier for two consecutive months, the rate drops without renegotiating. Project your growth credibly with your own numbers.
Is the chargeback reserve really negotiable? Yes. A clean history (under 0.3 % disputes) justifies a reserve cut to 5 % and release at 30 days rather than 90.
Is the 24-month lock-in mandatory? Rarely. Many aggregators accept 12 months, or none, in exchange for a slightly higher rate. Compare total cost over your real expected duration.
Are these tiers the same everywhere? No, they are 2026 order-of-magnitude figures for Nairobi and Douala. Each aggregator has its own grid: request it in writing and compare at least two offers.
