U.CASH charges nothing on the PromptPay rail. Thai banks send PromptPay transfers free or near-free. Settlement is seconds, around the clock. Orders hold for 30 days.
PromptPay runs as a manual rail: the buyer initiates the transfer against your published coordinates and includes the per-order payment reference, which is what makes the reconciliation one click rather than a hunt. Settlement lands in the rail's own window, which the fees and settlement section states; there is no processor in the middle to wait on. That directness is also the operational trade: the rail sees a plain transfer, so the reference discipline is what keeps reconciliation mechanical.
The currencies PromptPay settles, THB, also exist on-chain where peg families trade: settle the same corridor as a token, non-custodial, final on confirmation, at network fees instead of rail fees. Buyers choose their rail; your ledger sees the same currency either way. The operational difference worth planning around is reversal: the crypto leg settles finally with no dispute window, which suits invoices and known customers, while the traditional rails keep the protections and processes their buyers expect.
