The verdict in three sentences
Between 60 and 75 % of carts are abandoned, and most of it happens at payment: forced account, surprise fees, payment too slow. The winning decision combines a simplified guest checkout (adding about 10 % conversion) and an immediate WhatsApp reminder (recovering 15 to 20 % of lost carts). 1-tap mobile money — Wave, Orange Money, MoMo — removes the final friction and turns intent into a sale.
Why carts die at payment
An abandoned cart is not a lost customer: it is a customer who hit a specific obstacle. Identifying them lets you fix them one by one rather than rebuilding the whole funnel.
| Abandonment cause | Estimated weight | Fix |
|---|---|---|
| Mandatory account creation | 22 % | Guest checkout by default |
| Fees/shipping shown too late | 18 % | Fees visible from the cart |
| Payment too slow or failing | 17 % | 1-tap mobile money |
| Slow site at payment | 14 % | Payment page < 2 s |
| Lack of trust/security | 11 % | Badges, reviews, visible contact |
| Final price too high | 10 % | Promo codes, pay in 2 |
| Others (distraction, comparison) | 8 % | Multichannel reminder |
Recovery tactics and their yield
A reminder is not spam: it is a useful nudge sent on the right channel at the right time. Local mobile money makes resuming payment nearly instant.
| Tactic | Send delay | Recovery rate | Cost |
|---|---|---|---|
| WhatsApp reminder | Day 0 (30-60 min) | 15 to 20 % | near zero |
| WhatsApp follow-up reminder | Day 1 | +5 to 8 % | near zero |
| Email reminder | Day 0 to Day 2 | 4 to 6 % | low |
| SMS with payment link | Day 0 | 8 to 12 % | ~15-25 FCFA/SMS |
| -5 % promo code (2nd reminder) | Day 2 | +6 to 10 % | margin |
| Guest checkout (preventive) | immediate | +10 % conversion | one-off |
The most profitable combination in Senegal, Côte d'Ivoire and Nigeria: guest checkout + Day-0 WhatsApp reminder with a mobile money payment link. The customer resumes where they stopped and pays in one gesture.
Mini case study
Fatou sells cosmetics in Lagos: 1,000 carts created/month, of which 680 abandoned (68 %), average basket 15,000 FCFA. Without reminders, those 680 carts = 0 FCFA. She turns on a Day-0 WhatsApp reminder with a 1-tap payment link: 18 % recovered = 122 orders = an extra 1.83 M FCFA/month. Adding a guest checkout (she previously forced account creation), base conversion also rises by 10 %. Setup cost: about 250,000 FCFA, repaid in under two weeks.

Why does WhatsApp recover better than email?
Because in West Africa WhatsApp is opened several times a day and read rates exceed 90 %, versus 20 to 30 % for email. A WhatsApp reminder sent within the hour recovers 15 to 20 % of carts, three to four times more than email.
Is guest checkout risky for retention?
No. You capture the phone number and email at checkout, so you can retain customers afterward. Forcing an account before purchase costs about 22 % abandonment for almost no benefit.
When should I remind without being intrusive?
The optimal window is 30 to 60 minutes after abandonment, while intent is still warm. A second reminder at Day 1 is acceptable; beyond two messages, yield drops and annoyance rises.
Does mobile money really change the abandonment rate?
Yes. A 1-tap Wave or Orange Money payment avoids card entry and bank failures, the main cause of technical abandonment. It is common to see -15 to -20 % payment abandonment after switching to 1-tap mobile money.
Should I offer a promo code in the reminder?
Not in the first message, or you train customers to abandon to get a discount. Reserve the -5 % promo code for the second reminder, only for those hesitating on price.
