Hi Chrisbrownsgardenmaintenance, you can sync your eBay data with QuickBooks Sole Trader Plus using a supported connector within the product. To get started, navigate to My Integrations iconbeside the Settings icon. Search for available eBay connectors in the search bar and click Get Integration Now. Once done, you'll be able to link your eBay account and begin syncing your data automatically.
Regarding Vinted, QuickBooks doesn't currently have a direct integration for it. I recommend searching for a third-party bridge application outside of QuickBooks to connect the two.
