The verdict in three sentences
A flat per-transaction fee (like Paystack's +NGN 100) turns small baskets into money pits: on a NGN 1,000 sale, that NGN 100 is a 10% effective fee. The fix is not to switch provider but to set a minimum order value derived from the fee math. The most profitable lever: bundling, which raises the average basket and dilutes the flat fee.
The effective fee collapses as the basket rises
A "1.5% + 100 flat" fee does not read at the same rate depending on the amount. Here is the real effective fee by basket tier.
| Basket | Fee (1.5% + 100 flat) | Effective fee |
|---|---|---|
| 500 FCFA | 107 FCFA | 21.4% |
| 1,000 FCFA | 115 FCFA | 11.5% |
| 2,500 FCFA | 137 FCFA | 5.5% |
| 5,000 FCFA | 175 FCFA | 3.5% |
| 10,000 FCFA | 250 FCFA | 2.5% |
| 20,000 FCFA | 400 FCFA | 2.0% |
Below 2,500 FCFA, the effective fee tops 5% and devours a small product's margin. Above 10,000 FCFA the flat fee becomes negligible. Your minimum order should target an effective fee below 3%.
Bundling against the flat fee
Compare a shop selling per unit vs the same shop enforcing a minimum basket via bundling, over 300 orders/month.
| Strategy | Avg basket | Effective fee | Net margin / order |
|---|---|---|---|
| Unit sale | 6,000 FCFA | 3.17% | Low |
| 2-item bundle | 12,000 FCFA | 2.33% | Medium |
| Bundle + free-delivery threshold 15,000 | 15,000 FCFA | 2.17% | High |
Raising the average basket from 6,000 to 12,000 FCFA not only cuts the effective fee by a point, it lifts total volume: a free-delivery threshold at 15,000 FCFA mechanically nudges the customer to add an item. The same logic makes small baskets profitable AND grows revenue.

Mini case study
Aminata, who runs an online grocery in Lagos, was stuck with a 4,500 FCFA average basket and a 3.7% effective fee. By creating "meal baskets" at 12,000 FCFA and offering free delivery above 15,000 FCFA, her average basket rose to 13,000 FCFA. The effective fee dropped to 2.3%, and above all her revenue jumped 35% at constant order volume. On 250 orders/month, that is roughly 2.1M FCFA of extra monthly revenue.
FAQ
Why is a flat fee so punishing on small baskets?
Because it does not shrink with the amount: a flat 100 FCFA is 20% on a 500 FCFA basket but only 0.5% on 20,000 FCFA. The smaller the basket, the more the effective fee explodes.
How do I set my minimum order value?
Target an effective fee below 3%. With a 100 FCFA flat fee, that means a minimum around 5,000-7,000 FCFA. Below that, each sale bleeds too much margin.
Doesn't bundling scare customers off?
Built well, no: a bundle offers perceived savings while raising your basket. The customer feels they got a deal, you dilute the flat fee.
Does the free-delivery threshold really help?
Yes, it is one of the strongest levers: set just above your average basket, it pushes the customer to add an item to reach it, lifting both basket and volume.
