Hello sylvaino,
Having the opportunity to complete all of your business tasks through one program is a great option, so I can appreciate why you'd be looking to also pay your suppliers directly through QuickBooks Online. I can go over this with you.
At QuickBooks, our goal is to provide users with the features that help them optimally manage their books. A lot of the features that are added are based on input from users using the Feedback option, and that's what I suggest to you now. I don't have information on when or if being able to pay suppliers directly through QuickBooks Online will be available, but you can share your voice on this request by leaving feedback. Here's how it's done: How do I submit feedback?
To keep in the know with new features added to QuickBooks Online, feel free to bookmark our QuickBooks Online Feature and Product Updates page, where our team shares information about new and upcoming features to the program.
In the meantime, you can go with what @LeithG suggested and use a third-party service or app that syncs with QuickBooks Online to get the job done. Whether you use Plooto as they've suggested or go with another option, you can use and review the Apps tab in your QuickBooks Online account to see what's available. Some services also offer third-party integrations which are done from their end of things rather than through QuickBooks Online.
I hope this has been helpful for clarifying your options. I'll be here if you have further questions.
