Start with the invoice
A connected checkout passes the intended amount from the billing software to a supported payment integration. This reduces the need to enter the same amount twice and gives the workflow a shared transaction reference.
Understand the result
Approved, declined, cancelled and pending are different states. The software should record the actual result. If the connection times out, the operator needs a supported status check before trying again.
Ask the right questions
Ask which provider, device and software edition are supported; how refunds work; how settlement is reconciled; and what staff should do if a result is delayed. Availability depends on the agreed integration.
