Where each one falls short

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

Mercury

  • Treasury access requires a $250,000 balance held with Mercury
  • Non USD international wires carry a 1% conversion fee
  • Choosing OUR wire coding, which covers intermediary bank charges, costs $15 per wire
  • ACH invoicing is $1 per transaction on Mercury Plus and only free on the $299 a month Pro plan
  • Advanced and recurring invoicing require Mercury Plus at $29.90 a month

Paddle

  • Paddle charges 5% plus 50 cents on every checkout transaction, which is well above a bare payment processor rate
  • The 50 cent fixed component falls heavily on low value sales, and products under $10 require custom pricing agreed with sales
  • Invoicing is not covered by the published rate and requires custom pricing
  • As a merchant of record Paddle sits between the seller and the customer, so payouts and tax handling run through Paddle rather than the seller's own processor
