The verdict in three sentences
Forcing users to create an account before paying kills mobile conversions. In Dar es Salaam, guest checkout lifts completion by 22%, while a post-purchase opt-in still recovers 31% of emails. The right sequence: pay first as a guest, create the account after purchase.
The friction of a forced account
A customer ready to pay does not want to fill a signup form, pick a password and confirm an email. Every step before payment is an exit. The account must be a post-purchase bonus, never a toll gate.
| Signup field | Friction | Guest alternative |
|---|---|---|
| Email + confirmation | High | Phone only |
| Strong password | High | OTP by SMS |
| Email verification | Very high | None |
| Full profile | Medium | Filled after purchase |
| Marketing consent | Low | Optional after purchase |
| Saved address | Useful | Saved post-purchase |
Conakry confirms the cost: forcing an account accounts for 39% of cart drop-offs; guest checkout recovers them.
OTP versus password: the right mobile choice
Across West and East Africa, passwords are needless friction when the phone is enough. An OTP by SMS or WhatsApp authenticates effortlessly and sets up the loyal customer.
| Method | Login time | Failure rate | Loyal-buyer retention |
|---|---|---|---|
| Classic password | 35s | 18% (forgotten) | baseline |
| OTP SMS | 15s | 6% | +12% |
| OTP WhatsApp | 12s | 4% | +15% |
| Saved wallet | 8s | 2% | +21% |
| No account (guest) | 0s | 0% | convert later |
A wallet saved after the first purchase turns a guest buyer into a loyal customer: the second checkout takes 8 seconds.

Mini case study
Neema, who runs a fashion shop in Dar es Salaam, forced account creation: on 600 carts, a large share dropped at that step. Enabling guest checkout with WhatsApp OTP recovers most of them. Completion climbs 22%, i.e. about 130 extra sales a month. At TZS 45,000 per cart, that is meaningful additional revenue, and 31% of emails are still captured after purchase for follow-up.
