What is the difference between ACH in the US and SEPA Instant in Europe for cross-border B2B payments?

ACH (Automated Clearing House) is the standard US electronic network for domestic batch payment transfers taking 1-3 business days, whereas SEPA Instant (Single Euro Payments Area) in Europe executes 24/7 euro credit transfers within 10 seconds across 36 European countries.

How does SynthFintech calculate fee savings for B2B multi-currency merchant accounts?

SynthFintech simulates real-time FX markups, fixed transaction fees, and cross-border routing costs across SWIFT, ACH, and SEPA networks to provide transparent side-by-side fee comparisons and net annual savings.

How does PSD3 impact B2B cross-border payment gateways in the EU?

PSD3 (Payment Services Directive 3) and PSR (Payment Services Regulation) enhance Strong Customer Authentication (SCA), combat authorized push payment (APP) fraud, and enforce non-discriminatory IBAN access across European financial institutions.
