I’d recommend using the drawer pay in/out feature. This will record these transactions in your drawer report, both the digital and print versions (if you use the print feature).
On your Register, go to Reports > Drawer Reports. Next, tap “Paid In/Out” and you’ll be taken to a screen where you can enter the dollar amount of the payment to your supplier. Enter the amount and type in a note for the description; I recommend the name of the supplier. Choose “Paid Out” to complete the transaction.
When you close your drawer at the end of the day you’ll see a list of the pay outs for the day. The anticipated amount in your drawer will also reflect anything paid out. I find it very easy to use since I can just go through my cash drawer report history to locate any pay outs.
This article also has a handy overview of how to do a pay out.
