Hello katie10,
Managing your suppliers is an important part of your business. With QuickBooks online, you can record your operations and keep an eye on your business expenses. Here's a community link with a suppliers overview: https://quickbooks.intuit.com/community/Help-Articles/Suppliers-overview/m-p/261948.
If you paid your supplier and they don't see the money in their bank account, I suggest you get in touch with the financial institution you submitted the payment through. They'll be able to help you resolve this situation.
Reach out if you have any other questions.
