Hi there brooke-matter-ap,
It's vital that all of your accounts are set up correctly so that all your books will end up being balanced. QuickBooks Online is a great tool that's able to connect to various services through apps in order to import and export different types of data. I can provide some information about apps.
QuickBooks Online itself can't directly connect with a service such as Novatek. However, there are apps created by various third-party developers available to connect with different services. To see if there are any apps available to connect with the services you use, navigate to the Apps tab and search for the name of your service.
If you can't find any apps available for your service, another way to possibly connect your services to QuickBooks would be through your service provider's site. There may be a function on their site that connects directly with QuickBooks Online.
If you have any other questions, feel free to reach out here.
