Welcome to the Community, @GCAGsc.
You can set up the artists as vendors in QuickBooks Online. The program tracks the payments to these consignors and once the amount reaches the $600 threshold, they'll receive a 1099.
Follow these steps to add them in QBO:
- From the Expenses menu, select Vendors.
- Click the New vendor button.
- Enter the artist's details in the Vendor Information window.
- Place a checkmark in the Track payments for 1099 box, then hit Save.
Check out this article for the details: Add contractors or vendors when preparing 1099s.
For consignment sales and payouts, I recommend visiting this link for reference: How to record consignment sales.
