Inventory Lab

  • Multichannel listing requires the separate UniCon add-on, priced from $49 to $449 per month depending on tier

Shopify

  • Using any payment provider other than Shopify Payments adds a transaction fee on top of the card rate, at 2% on Basic falling to 0.2% on Plus
  • That fee makes the cheapest plan the most expensive place to use an outside processor, which is the opposite of how plans usually work
  • Card rates also improve with the plan, from 2.9% on Basic to 2.7% on Advanced
  • Amex is charged at a higher rate than other cards on every plan below Plus
  • Plus starts at $2,300 a month
  • The advertised lower monthly prices require paying a year up front
