Honest comparison
Apex Applications vs InventoryLab / Seller 365
InventoryLab is now presented within Threecolts Seller 365, so the thing you would buy is the bundle rather than the standalone product people remember. Compare the current bundle's listing and shipment functions and its accounting workflow, not the legacy description. On our side, be clear about state too: Apex Red, which covers the shipment and prep workflow, is in beta.
