The verdict in three sentences
Forcing a new customer to create an account before paying is one of the costliest conversion killers. Guest checkout removes that block and gains 15 to 30 % on first purchases. The right 2026 architecture: guest by default, then opt-in account after purchase, to capture emails and numbers without ever blocking the sale.
Three account policies compared
The account has real value — repeat purchase, history, remarketing — but its placement changes everything. Imposed before payment, it costs more than it earns.
| Policy | 1st-purchase conversion | Repeat purchase | Contact capture | Verdict |
|---|---|---|---|---|
| Mandatory account before purchase | Baseline −15 to −30 % | +20 % | High | Avoid |
| Pure guest | +15 to +30 % | Baseline | Low | Good for acquisition |
| Guest + opt-in account post-purchase | +15 to +28 % | +12 to +18 % | Medium-high | Recommended |
| Account via MoMo number only | +10 to +20 % | +15 % | Medium | Simple and effective |
| Optional social login | +8 to +16 % | +10 % | Medium | Complement |
The effect on remarketing and repeat purchase
The debate is not only immediate conversion: an account raises customer lifetime value. The trick is to offer it at the right moment.
| Metric | Pure guest | Mandatory account | Post-purchase opt-in |
|---|---|---|---|
| Buyers refusing the account | — | 25-35 % lost | 0 % lost |
| Account acceptance rate | — | Forced | 40-55 % |
| Emails/numbers collected | 30-45 % | 90-100 % | 60-75 % |
| 90-day repeat purchase | Baseline | +20 % | +12 to +18 % |
| Cost on initial conversion | None | High | Near zero |

Aïcha sells natural cosmetics in Accra, 900 visits/month, average basket 18,000 FCFA (approx. €27). With a mandatory account, her conversion caps at 1.2 %, i.e. 11 orders. Switching to guest checkout with a post-payment opt-in account, she targets +22 %, i.e. 1.46 % and 13 orders, while capturing the wallet number of 50 % of buyers for her WhatsApp follow-ups. Estimated monthly gain: 36,000 to 54,000 FCFA, plus a contact base that grows every week.
FAQ
Does guest checkout lose customer data? Less than you think. By offering the opt-in account after payment, 40 to 55 % of buyers accept, and you already collect number and address during purchase for remarketing.
Doesn't a mandatory account improve loyalty? It raises repeat purchase by +20 %, but only for those who buy. Since it drives away 25 to 35 % at entry, the net balance is negative on acquisition.
Can you create an account with just the mobile money number? Yes, and it is often the smoothest local option: an account tied to the MoMo number gains 10 to 20 % conversion while keeping a reusable identifier.
When should I ask for account creation? After order confirmation, on the thank-you page: "Create your account to track your delivery." This timing reaches 40 to 55 % acceptance with no risk to the sale.
Is social login worth it in West Africa? As a complement, yes, with +8 to +16 % conversion, but it does not replace guest: many prefer to connect nothing and pay directly via mobile money.
