Practical Playbooks

• Invoicing & receivables. Issue invoices in EUR/USD. For crypto-forward companies, utilize compliant stablecoin rails to speed up settlements where fiat rails are too slow.
• Supplier payouts. Build approval chains with policy limits. Run mass payouts to EU and global partners via SEPA and SWIFT as needed. Ensure all compliance documentation is attached to cross-border flows.
• Treasury ops. Document corridor-specific cut-offs (e.g., SWIFT T+2) and plan liquidity accordingly. Use multi-currency support to hold operating capital in the currencies you need most.

FAQs

What makes a platform “international” vs a standard B2B payments tool?

It provides multi-currency support and cross-border rails (SEPA/SWIFT) with predictable settlement and compliance suitable for corporate KYB—not just card acceptance.

How should companies compare FX markups and fees across providers?

Normalize everything to an all-in rate: mid-market markup + per-payment fee. Test a sample invoice across vendors to compare the real cost.

What onboarding/KYB hurdles do cross-border businesses face?

Expect UBO verification, source-of-funds, and sanctions/PEP checks. Platforms like KEA specialize in unifying this process for both fiat and crypto operations.

How do these platforms integrate with ERP/accounting?

Look for exportable statements and API capabilities to automate your month-end close and map payments to your ledger.
