Our rate schedules are checked continuously against official developer documentation, central bank mandates (such as SAMA in Saudi Arabia, Banxico in Mexico, and RBI in India), and processor legal pricing updates.
Can I request a new payment gateway or marketplace calculator? ▼
Yes! Use our contact form to submit requests for new payment gateways, regional banking rails, or specialized marketplace fee calculators. Our engineering team prioritizes additions based on merchant community demand.
Do you offer custom fee calculation widgets or API integration for enterprises? ▼

What is the typical response time for support and rate inquiry submissions? ▼
Our global merchant support desk typically reviews and responds to all rate update inquiries, calculation feedback, and enterprise partnership requests within 24 to 48 business hours.
How do I report an unannounced processor rate change or fee discrepancy? ▼
If your payment processor has altered its public schedule or introduced a new regulatory compliance surcharge, please provide a link to the official processor notice or merchant statement excerpt via our contact form for expedited review.
Can I integrate FeeFlow's calculation engine directly into our ERP or billing software? ▼
Yes. We license headless algorithmic fee calculation modules and webhook engines for accounting software, invoicing suites, and marketplace platforms requiring real-time gross-up calculations.
Does FeeFlow provide formal financial, legal, or tax advice? ▼
No. FeeFlow provides algorithmic calculations and educational estimates for operational planning. For formal statutory tax filing, nexus determinations, or legal contract negotiations, merchants should consult a licensed CPA or legal counsel.
