The verdict in three sentences
A "pending" payment is neither a success nor a failure: it's a temporary state between the attempted charge and confirmation. The 2026 best practice is an expiry window (typically 2 to 15 min) with automatic polling, never a blind manual decision. Statistically, around 92% of pendings resolve to success — the key is to release or cancel nothing before the final outcome.
Why a payment stays pending
Causes are almost always network- or customer-side, rarely a bug in your code. A slow USSD, a late PIN entry, a saturated provider: the payment floats for a few minutes.
| Cause | Relative frequency | Typical window | Likely outcome |
|---|---|---|---|
| Slow USSD network | high | 2-5 min | success |
| PIN not entered in time | medium | 3-10 min | failure (timeout) |
| Saturated provider (peak) | variable | 5-15 min | delayed success |
| Insufficient balance | low | immediate | failure |
| Customer abandons | medium | 15 min max | expiry |
Rule: never show "failure" before the window expires. A customer who sees "failure" while their payment is about to succeed will often pay again — and now you have a double charge.
The three-state status policy
An order moves through three clear states. The transition happens via webhook OR getStatus polling, never by hand.
| Status | Meaning | System action | Customer message |
|---|---|---|---|
| pending | Payment in progress | Hold stock, ship nothing | "Payment in progress, please wait…" |
| success | Confirmed | Validate order, release prep | "Payment confirmed ✓" |
| failed | Failed/expired | Release stock, offer retry | "Failed, please retry" |
The safety window: after 15 minutes without confirmation, mark failed, release reserved stock, and invite a retry. Treat the rare late confirmations as orphans to reconcile.

Mini case study
Fatou sells fabrics online in Thiès: 900 orders/month. About 7% pass through a pending state, i.e. 63 orders/month. At first she cancelled every pending after 3 min: she lost ≈ 40% of sales that would have succeeded, i.e. 25 orders × 15,000 FCFA = 375,000 FCFA/month evaporated. By extending the window to 12 min with getStatus polling every 30 s, 92% of pendings confirmed. Recovered sales: ~350,000 FCFA/month, with not a single double charge.
FAQ
How long should I leave an order pending? In 2026, a 2-to-15-minute window covers nearly all cases. Beyond 15 min, mark it failed and release stock; later confirmations are handled in reconciliation.
Should I ship a pending order? Never. Pending means the money isn't confirmed. Wait for success; shipping a pending order means giving away goods if the payment fails.
What message should I show the customer? A reassuring, active message: "Payment being validated, don't close this page…". Avoid a premature "failure," which pushes re-payment and thus double charges.
What share of pendings ends in success? 2026 order of magnitude: around 90 to 92% with a proper window and polling. The remaining 8-10% are genuine failures (PIN timeout, insufficient balance, abandonment).
How do I handle confirmations that arrive too late? Treat them as orphans: match them to unfulfilled sales, contact the customer, and fulfill or refund. A good transaction log makes this trivial.
