I bought and used an APP called Transaction Pro, installed the program/app and in the Target in program properties I typed "C:\Program Files (x86)\Transaction Pro\Transaction Pro.exe" /RECPAY3.
When I setup the excel worksheet, I when I applied a check payment from the customers for instance and I used the same check number but added ".001" to the check. For Example if check # 1108 paid four invoices from four different customers I would show on the Excel Worksheet Ck # 1108.001 on the first Line (row), Ck # 1108.002, on the second row, etc. I then imported the Excel worksheet (csv) into Quick Books. For example the columns looked like this:
| Date | Type | Check Number | Apply to Invoice | Amount | Deposit To | Discount Amount | Discount Acct | Memo | AR ACCT |
