Pass On or Absorb Mobile Money Fees: Who Pays on Your Store?

The verdict in three sentences

On a Senegalese online store, absorbing mobile money fees protects conversion but eats 1 to 3.5 margin points depending on the payment method. Passing the surcharge on at checkout protects margin, but pushes cart abandonment up by nearly 11% the moment it appears. The right answer is neither extreme: it depends on your gross margin, monthly volume, and dominant payment channel.

The 2026 merchant fee grid

Every payment method has its cost. Here are the 2026 order-of-magnitude merchant rates in Senegal (exact rates depend on your contract and volume).

The glass half full: Wave is the cheapest way to collect for a local store, and it is often customers' preferred channel. The glass half empty: the moment a buyer pays by card, your cost quadruples.

Absorb or pass on: the margin simulation

Take a store with a 22% gross margin (typical Senegalese retail), a 15,000 FCFA average cart, i.e. 3,300 FCFA gross margin per order. Here is the fee impact by strategy and volume.

At 500 orders/month, absorbing a 1.8% fee mix costs 135,000 FCFA in margin per month, close to 1.6 million FCFA a year. Passing it on recovers that sum, but at the cost of a less frictionless checkout.

The practical conversion-threshold rule

A visible surcharge loses an average of 11% of conversion at checkout. If your average cart yields 3,300 FCFA of margin, losing 11% of buyers to save 270 FCFA of average fees only pays off if your traffic is abundant and price-insensitive. The winning hybrid strategy in 2026:

• Absorb on Wave and Orange Money (low fees, majority channel) to keep conversion.
• Pass on card fees only (3%+), where international buyers accept a surcharge more readily.
• Quietly bake 1% into the catalog price rather than showing a "fees" line that triggers abandonment.

Mini case study

Awa runs a cosmetics store in Dakar: 180 orders/month, 15,000 FCFA average cart, 22% gross margin. 70% of her sales go through Wave (1%), 25% through Orange Money (1.8%), 5% by card (3.2%). Her monthly fee cost if she absorbs everything: about 34,500 FCFA. By passing on only card fees and baking 1% into her listed prices, she recovers ~28,000 FCFA/month in margin while keeping a surcharge-free checkout on 95% of her sales. Over a year, that is 336,000 FCFA preserved without touching her conversion.

FAQ

Is it legal to charge payment fees to the customer in Senegal?

Yes, nothing forbids it, provided the amount is clearly shown before checkout. Transparency is also a requirement of the mobile money operators. Keep the surcharge honest, between 1% and 3% by method.

Which payment method is cheapest for the merchant?

Wave merchant, around 1% with no fixed fee, remains the most economical option in 2026 for a local store. Orange Money sits at 1.5–2%, bank cards at 2.5–3.5% plus a 100 FCFA fixed fee.

Does passing on fees really scare customers away?

A visible surcharge at checkout raises abandonment by roughly 11% on average. The trick is to bake a small margin into the catalog price rather than adding a "fees" line at the last second.

At what volume should you optimize fees?

From 150–200 orders/month, the gap between absorbing and passing on often exceeds 30,000 FCFA monthly. Below that, simplicity wins: absorb and focus on growth.

Can you set different fees by payment method?

Yes, a well-built store applies a per-method rule: 0% surcharge on Wave/OM, +2.5% on card. That is exactly the kind of logic we wire into our clients' checkouts.
