Applying payments from multiple sources
Using Quickbooks Desktop, I record a $100 as Statement Charges for a customer named Sam. Now Sam pays $40 and using Receive Payments I record the details. Now the remaining $60 is paid by a different organization named ABC (think it like a subsidy payment). One way to record this payment is via Receive Payments for Sam and then in memo field enter relevant details of ABC. But then one can't track the payments of ABC (or generate reports) as the payments from them could be for multiple customers and the details are buried in the memo field. So how can one achieve this?
My first thought was to do something like this i.e. create a credit for the payment from ABC but assign it to Sam.The journal entry to do this would be.
| Account | Debit | Credit | Name |
| Bank | $60 | ABC | |
| A/R | $60 | Sam |
And then apply the credit using Receive Payments for Sam to the specific charge. However this is not possible since $60 does not show up as an outstanding credit for Sam. Given this limitation, how can one solve the underlying issue of applying payments from multiple sources and assign to a statement of charge while being able to track them.
