If a payment appears in a customer's Payment History but no disbursal was received, it may have been manually added by your organisation.
Payments received outside of Access PaySuite DDCMS (e.g., via BACS or cash) aren't processed by the system but can be manually recorded.
To check if a payment was manual, review the Payment Type and Payment Method in the Payment History tab - manual entries won't show as Direct Debit.
