Hi there glenile,
I can see how organizing information such as available payment methods for your supplier would make doing your books and paying your bills an easier process. QuickBooks Desktop makes it easy to keep your supplier information organized and I'd like to explain one way that you can enter this information into your supplier profile.
Start by accessing the Supplier Centre by choosing Suppliers from the left-side menu, or by navigating to Suppliers then picking Supplier Centre from within the File menu. It sounds like you're already familiar with adding suppliers, but I'd like to draw your attention to the Notes field in your Supplier Information page. Across the page you'll see tabs such as Transactions, Contacts, To Do's, Notes, and Sent Email. Navigate to the Notes section. This is where you can enter information that there's not a already a specific field for like accepted payment methods.
Since it sounds like having a specific field for this information would be beneficial to your business, I suggest submitting feedback to our product development team. They are responsible for future program updates and improvements and love hearing from customers like you. To submit feedback, navigate to the Help menu, then choose the option for Feedback.
I wish you all the best!
