There are 2 ways you can do tis - My preferred method is the first one as it is easy to see one payment for one amount.

In the A/P payment module select the icon that says 'enter vendor prepayments', that will open up another box at bottom for you to enter your information in. Fill in everything as you normally would but this time enter the 100.00 in the 'Prepayment Amount' box on the bottom right. The 'Prepayment Reference No.' to the bottom left should automatically populate the Cheque No but it is a good idea to also enter the Chq date next to it.

The second is same as above except that you can enter the full 95.00 against the invoice and then enter the 5.00 into the 'Prepayment Amount' box.

Then Post.

Next time you open this vendor in the A/P payment module you will now see in red typing the 'prepayment amount. It will only have the Chq nbr and the amount hence why I suggest to also add the date at end of cheque nbr so that you know when this was created.

Do a save as first of your data and try both ways to see how it looks in the A/P payment module and also in the vendor aged detail listing.

Thanks so much for your help :) You're the best!
