Thanks for the reply but having trouble following you.

How do we "treat the payment as on Account"?  Do it at Banking >> Deposits?

How do we "pay by allocation"?  Do it at Sales >> Allocate Customer Payments or Credit Notes?

I actually tried doing this before trying Customer Payments but did not see where to enter check number.

Thanks for the reply.  Accounting wants to be able to see the check number on some of the reports and be able to find the payment using the check number (ie to allocate the payment); so I don't think Memo box will work.

When entering a payment from customer (from Sales >> Customer Payments), we do not see a box for check number (nor for payment type, ie check).  We thought about using the Reference box but issue arises when we tried to enter the same value for the Reference box.  System would not allow us because “the entered reference is already in use”.

Are we going to the wrong page to do customer payment?  I checked setup and do not see an option to add a check number box (nor payment type box) to the form.  We need to be able to enter multiple payments with the same check number.  Is this possible?  Any help will be greatly appreciated.
