โ๏ธTechnical & Educational Details
Payment processing fees combine variable interchange fees with fixed base fees. On low-ticket digital products ($3.00 to $10.00), fixed fees (e.g., $0.30) disproportionately erode merchant margins, raising the effective fee to 10% or more. Choosing localized payment methods like iDEAL or SEPA Direct Debit eliminates percentage overhead for European transactions.

- Pricing low-ticket digital assets and micro-transactions to avoid losing 15%+ to gateway fixed fees.
- Comparing international PayPal transaction costs against European Stripe credit card processing.
