The verdict in three sentences
On mobile, every extra checkout field costs about 7 % of conversion — and a long payment flow is the top cause of abandonment in Lagos. A two-click Paystack Inline checkout (embedded modal, no redirect, saved details) cuts abandonment from 69 % to 41 %. At the same traffic, that's revenue gained without spending a naira more on ads.
How field count drives conversion
Less friction, more sales. Here is the effect of checkout format on a Lagos store, 2026 orders of magnitude.
| Checkout format | Fields | Time (s) | Abandonment | Completion |
|---|---|---|---|---|
| Classic form | 8 - 10 | 90 - 120 | 69 % | 31 % |
| Simplified form | 5 - 6 | 55 - 70 | 55 % | 45 % |
| Paystack redirect | 3 - 4 | 30 - 45 | 48 % | 52 % |
| Paystack Inline (2-click) | 1 - 2 | 12 - 20 | 41 % | 59 % |
Moving from classic form to Inline means +28 points of completion — nearly doubling checkout success.
Revenue uplift over 1,000 sessions
Let's project the impact over 1,000 checkout sessions with an average basket of 20,000 NGN. Figures are a 2026 estimate.
| Format | Sales / 1,000 | Revenue | Uplift vs classic |
|---|---|---|---|
| Classic form | 310 | 6,200,000 NGN | — |
| Simplified form | 450 | 9,000,000 NGN | +2,800,000 NGN |
| Paystack redirect | 520 | 10,400,000 NGN | +4,200,000 NGN |
| Paystack Inline | 590 | 11,800,000 NGN | +5,600,000 NGN |
Inline generates +5,600,000 NGN per 1,000 sessions versus the classic form — with zero extra ad budget.

Amaka, who runs a ready-to-wear store in Lagos, received 1,200 checkout sessions/month with a 20,000 NGN average basket. Her old 9-field form completed at 31 %, or 372 sales (7,440,000 NGN). After integrating a Paystack Inline checkout, completion rose to 59 %, or 708 sales (14,160,000 NGN). Gain: +336 sales, or +6,720,000 NGN/month, for a one-off integration cost and no extra ads.
FAQ
Why does Inline convert so much better?
It kills manual typing and redirects: the payment modal opens in place, details can be saved, and the customer confirms in a tap. Each field removed cuts abandonment by roughly 7 %.
Should I drop the classic form?
Keep a fallback for customers who prefer another method, but put the Inline button first. Most mobile users pick the shortest path.
Does this work with mobile money too?
Yes. The same low-friction principle applies to MTN MoMo and other wallets via deep-links and pre-filled numbers. Ideally show both card and wallet buttons.
How long does it take to integrate a one-tap checkout?
On an existing store, expect a few days of development to wire the API, the modal and the confirmation webhook, followed by a testing phase.
