When an invoice (sales or purchase) needs to be only partly paid/received there are two ways you can enter this.
Firstly you will be asked if you want to Save.
Then should you wish to, you can enter details of the payment on Account or just press OK.
This will put the amount you paid ON ACCOUNT in a special control account called @PONA (or @SONA)
It will show in cash flow reports under control accounts and not under the relevant nominal.
If you are using KEYPrime Property unless you enter the tenancy details it will not show on any tenancy reports.
2. PART PAYMENTS Enter your Purchase Payment and when the line(s) of invoices get listed on the bottom half of the screen, then put a Y if you are paying the WHOLE of an invoice or P if you are paying PART of one.
If there is only ONE line of detail on your invoice then the amount will automatically be allocated, in part, to that line.
If there is more than one line or you want to DEFINE WHAT IS BEING PAID, then click on ITEMS, and allocate the amounts as you want to VAT and NET.
If this is the SECOND PART PAYMENT then you will need to press ITEMS, even if there is only one line of detail.
