The verdict in three sentences
Instant settlement costs a little more (often +0.3 to +0.5 point), but frees your money the same day instead of T+1. Whether that surcharge pays off depends on your cost of capital: if every day of blocked cash forces an overdraft or denies you a profitable restock, instant pays for itself. In Nairobi in 2026, the switch point sits around a 15 %/year cost of capital and strong sales seasonality.
Fees, delay and tied-up cash: the comparison
Comparing instant and T+1 without pricing tied-up cash is looking at only half the equation.
| Option | Delay | Fees | Tied-up cash (8 M FCFA/month) |
|---|---|---|---|
| Instant rail | T+0 | ~1 % | 0 days |
| Standard aggregator | T+1 | ~1.5 % | ~1 rolling day (~265,000 FCFA) |
| Aggregator + instant option | T+0 | ~1.9 % | 0 days |
| Bank transfer | T+2/T+3 | low fixed | ~2-3 days (~530-800,000 FCFA) |
On 8,000,000 FCFA/month, one extra settlement day permanently ties up about ~265,000 FCFA (rolling). If your cost of capital is 15 %/year, that day costs roughly 3,300 FCFA/month in opportunity cost — to weigh against the instant option surcharge.
When instant pays off
| Annual cost of capital | Cost of 1 blocked cash day (8 M/month) | Instant surcharge (+0.4 %) | Instant worth it? |
|---|---|---|---|
| 8 % | ~1,800 FCFA/month | ~32,000 FCFA/month | No |
| 15 % | ~3,300 FCFA/month | ~32,000 FCFA/month | Rarely |
| Overdraft at 24 % | ~5,300 FCFA/month | ~32,000 FCFA/month | If cash peaks |
| Urgent restock (30 % margin) | value > surcharge | ~32,000 FCFA/month | Yes in high season |
The real trigger is not average cost but seasonality: in peak demand, having cash the same day to restock a high-margin product earns far more than the 0.4 point paid. In low season, standard T+1 is enough.

Mini case study
Sophie runs a ready-to-wear store in Nairobi, 8,000,000 FCFA/month, with two annual peaks (major holidays). In low season she stays on standard T+1 at 1.5 %. As the holiday peak nears, she activates the instant option (+0.4 %, i.e. ~32,000 FCFA for the month) to collect same-day and restock at 30 % margin: the freed cash enables 1,200,000 FCFA of extra restock, i.e. 360,000 FCFA of margin. For that month, the math is decisive.
FAQ
Is instant always worth its surcharge? No. With comfortable cash and low season, standard T+1 is more profitable. Instant is justified mainly in demand peaks or cash tension.
How much does one blocked cash day cost? On 8,000,000 FCFA/month, one extra settlement day ties up ~265,000 FCFA rolling, i.e. ~3,300 FCFA/month at 15 % cost of capital. Weigh it against the instant surcharge.
Is the instant rail really T+0? The instant rail offers same-day settlement at ~1 %. Most aggregators are T+1 at ~1.5 %, with an instant option at +0.4 point.
Can I enable instant only in high season? Yes, and that is the optimal strategy: instant during peaks, standard T+1 the rest of the year. You only pay the surcharge when it earns.
