Frequently asked questions
What is the best B2B platform for cross-border trade?
For African-funded corridors: KeyBS Pay — the only one on this list with registry-backed verification and escrow. For US/EU domestic-heavy payables: BILL or Tipalti by scale.
Can one platform do everything?
Rarely well. The common stack is an AP/workflow tool plus a cross-border execution specialist for the corridors it cannot price.
KeyBS Pay is a business payments platform built around Verify-Then-Pay: registry-backed beneficiary verification and TradeScore™ before funds move, global payouts through partner rails, China supplier payment capability, treasury tools and virtual cards. Registrations and security details are published for independent review.
