Hey there, @anna-brutyan.
Happy to see you here in the Community. If you're looking for available vendor management integrations in QuickBooks Online, I recommend checking out our Apps Marketplace. There's thousands of apps on there that integrate with QBO and you're sure to find one to suit your needs.
Let me know if you have any additional questions by shooting me a reply. I'm eager to help out in any way that I can. Have a safe and productive week!
