International billing
Fly.io routes payments through US/EU-led stacks. Domestic debit profiles often fail verification, renewals, or cross-border authorization.
What works
Use a funded Visa built for global SaaS and subscriptions — add it in Fly.io's billing or wallet and top up before renewals.
With Plu
Fund Plu from supported rails or stablecoins, enter your Plu Visa at Fly.io, and keep payments predictable.
FAQ
Will my Plu card work for Fly.io payments?
Yes. Plu issues a Visa card built for international merchant billing. Fly.io processes payments through standard card rails, so a funded Plu card with sufficient balance clears at checkout or on renewal — including recurring charges.
Why does my local card sometimes fail on Fly.io?
Fly.io bills through US- and EU-based processors. Domestic-only debit cards or bank cards without international authorization often get rejected at the network level — not by Fly.io itself. Plu is a Visa card explicitly built for cross-border SaaS and subscription billing, so authorization profiles match what Fly.io's acquirer expects.
How do I fund Plu before paying Fly.io?
Top up Plu via local bank transfer, mobile money in supported markets (M-Pesa, Wave, Orange Money, MTN MoMo), or USDT/USDC on Tron (TRC20) or Ethereum (ERC20). Stablecoins clear in seconds with sub-$1 network fees on Tron. Once funded, add your Plu Visa in Fly.io's billing settings and you're ready to pay.
