Hello @Malcolm Ziman. 

Thanks for participating on this thread. I'm here to share additional details on the answer provided by my friend, @MaryGraceS.

QuickBooks Online has different types of report you can use to review transactions. If you only want to see the paid bills of a specific vendor, you'll want to use and customize the Transaction List by Vendor report. 

This is also based on the recommendation provided by the article below:

Print more than 14 lines in the voucher section of my check?

Meanwhile, if you're referring to seeing a vendor's specific payment with the bills that go with it, you can pull up and modify the Bills and Applied Payments report. Regardless of whichever report you want to use, both can give the same information you need to show. 

Again, thanks for always helping us here in the Community! If you have other questions in mind, feel free to let me know. I'll be around!
