Why is the amount deposited in my account less than what I charged my customer?

Breezeworks Payments by Finix charges a fee of 2.9% + 30¢ per transaction and Square charges 2.6%+ 10¢  for a swiped transaction and 2.9%+ 30¢ for an invoice payment. This is automatically deducted from your customer’s payment before funds are deposited into your account.
