You have paid, and you want to see it land on your account straight away. Often it is quick, but "instant" is not guaranteed — a short delay between paying and seeing it is normal and not a cause for concern.
Why there can be a short gap
A payment passes through the banking network before it settles and is applied to your account. A card payment usually confirms within minutes to a few hours; a Faster Payments transfer is typically same-day; a Direct Debit settles on or just after the due date. During that window it may show as pending. See what a pending payment means and how long a payment takes to clear.
When to check
If a payment has not appeared well beyond the usual times — a transfer not showing after a couple of working days — check it. See when a payment doesn't appear and how to check whether a payment has reached us.
Do not pay again in a panic
Waiting a little beats paying twice. See I paid twice by mistake.
Credicorp lends to companies rather than to you personally, so this is business finance outside the consumer-credit regime. That does not change the practical steps below.
