FX guide

FX should be explicit, transparent, and auditable.

Source-fixed payments​

Use source-fixed quotes when the sender knows how much they want to debit.

Example: pay EUR 10,000 and receive the best available USD amount.

Target-fixed payments​

Use target-fixed quotes when the beneficiary must receive an exact amount.

Example: supplier invoice requires exactly USD 25,000.

Target-fixed flows may require additional fee handling because the source amount can change.

Displaying quotes​

Show users:

  • Source amount.
  • Target amount.
  • Currency pair.
  • Rate.
  • Fees.
  • Expiry time.
  • Estimated settlement time.
  • Whether quote is guaranteed or indicative.

Quote expiry​

If the quote expires, request a new quote. Do not silently execute at a different rate without user or policy approval.

Reconciliation​

Store quote IDs with payment records. Quote IDs help explain FX rate and fee differences during reconciliation.
