Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Inventory Lab

  • InventoryLab is no longer sold standalone and is now bundled into Three Colts' Seller 365 plans starting at $69 per month for a single user, rising to $199 per month for the Pro tier
  • Multichannel listing requires the separate UniCon add-on, priced from $49 to $449 per month depending on tier

Sellfy

  • Every plan caps annual sales volume: $10k on Starter, $50k on Business and $200k on Premium
  • Exceeding the cap forces a plan upgrade rather than an overage charge, so growth is a step change in cost
  • Maximum file size per digital product is tied to the plan, at 10 GB, 15 GB and 20 GB
  • Email marketing credits are metered per plan, from 2,000 to 50,000
  • Cart abandonment, upselling and the affiliate programme all require the Business plan
  • Payment processing fees from PayPal or Stripe are charged on top of the subscription
