The verdict in three sentences
In Lagos in 2026, payment abandonment is the biggest leak in your funnel: between the "Pay" click and the Paystack confirmation, you often lose more than one shopper in two. The cause is almost never price, but technical friction: broken redirects, too many fields, manual card and OTP entry. By cutting effort to three fields and an inline modal, a store routinely moves from 45 % to 72 % checkout conversion without adding traffic.
Exactly where shoppers drop off
The payment funnel plays out over four micro-steps. Each one has its own leak rate. Here is a 2026 order of magnitude observed on Nigerian stores:
| Checkout step | Average drop | Dominant cause |
|---|---|---|
| Choosing a payment method | 8 % | Too many options, no card/transfer clarity |
| Entering details | 18 % | Long form, forced account creation |
| Redirect to payment page | 22 % | Full-page redirect vs inline modal |
| OTP / PIN validation | 12 % | Manual entry, timeout, no auto-fill |
Stacked together, an unoptimised funnel converts only 40 to 48 % of shoppers who reached payment. The good news: the three biggest leaks (form, redirect, OTP) are fixed in a few days of development.
The before / after, optimisation by optimisation
Each lever delivers a measurable gain. Here is the typical, cumulative impact on checkout conversion:
| Optimisation | Before | After | Gain |
|---|---|---|---|
| Cut to 3 fields (name, phone, amount) | 45 % | 52 % | +7 pts |
| Paystack inline modal (no redirect) | 52 % | 61 % | +9 pts |
| One-tap OTP (SMS auto-fill) | 61 % | 66 % | +5 pts |
| Payment logos + reassurance | 66 % | 69 % | +3 pts |
| USSD / bank transfer fallback | 69 % | 72 % | +3 pts |
The inline modal is the highest-ROI lever: it removes the full-page redirect where users leave your store and often never come back. Keeping payment on-page adds 8 to 10 points of conversion on its own. For feature phones, a USSD fallback and bank transfer via virtual account catch shoppers who cannot use card flows.

Mini case study
Chidi runs a cosmetics store in Ikeja, Lagos. He gets 900 checkout sessions per month, with an average order of NGN 22,000. His old funnel converts at 46 %, or 414 orders and NGN 9,108,000 in monthly revenue.
After the rebuild (3 fields, Paystack inline modal, OTP auto-fill), he reaches 71 % conversion: 639 orders, or NGN 14,058,000. Net gain: +225 orders and +NGN 4,950,000 per month, for a checkout rebuild that pays for itself in under two weeks. He did not raise his ad budget by a single naira.
FAQ
Should I really remove forced account creation? Yes. Requiring an account before payment costs on average 20 to 35 % of conversion. Offer guest checkout and capture the WhatsApp number after purchase to retain without friction.
Does the inline modal work on all phones? On smartphones, yes. For feature phones, always provide a USSD fallback and a bank transfer via virtual account, which cover the shoppers who cannot complete card or app flows, under 10 % of urban buyers.
How many fields should I show at most? Three are enough for a payment: name, phone, amount. Each extra field removes roughly 2 to 5 % of completion. Ask for the delivery address after payment is confirmed.
How long does it take to implement these optimisations? An optimised checkout (inline modal + OTP auto-fill + real-time status) usually ships in 5 to 10 days of development, testing included.
What realistic gain should I expect? From a 45 % baseline, targeting 68 to 72 % is realistic in Lagos in 2026. This is an order of magnitude: your exact gain depends on average order value and traffic.
