List Perfectly does not support variations on any platform but Poshmark (more platforms coming soon).  Here are some ways you can still list and crosspost variations manually with List Perfectly: Crosspost Variations from List Perfectly to Platform(s): every variation must be added as an individual product to your LP Catalog. If you have 20 shirts in the same design (10 blue, 10 red), you must Add 2 Products to your LP Catalog – 1 blue (10 quantity), 1 red (10 quantity).  Crosspost Variations from Platform to Platform(s): before crossposting, edit the listing to include any quantity and variation details that the platform offers. Then crosspost.
