You have me to help you create supplier transactions, -fm4a-co-za.
We can add a transaction either Expense, Cheque, or Bill.
You can do that by clicking the + New button and then select which of the mentioned transaction you want to create.
I've also added a reference that explains the difference between the three mentioned transactions: What is the difference between bills, Cheques, and Expenses?
As always, you can add a Reply if you have other concerns. I'll be happy to help you out!
