Settlement
The point at which a payment method says the seller has received final or usable value. What counts as final differs by method.

In practice
A card charge is captured and the funds become usable under the merchant's setup; the later payout to the seller's bank account is a separate event with its own timing.
The distinction
Settlement is not delivery, and delivery is not acceptance. A payment can settle while the work arrives late, omits a requirement or fails review — and a settled payment on one rail carries very different recourse from a settled payment on another.
Nine events, one word
Payment products use similar language for different things. A joined record separates them: commercial intent, delegated authority, credential, payment authorisation, initiation, clearing or transfer, settlement, ledger and invoice, and reconciliation or remedy.
The owner changes at almost every step. The buyer owns purpose and policy. A wallet or issuer owns the credential. A processor, bank or network records the payment event. Finance systems own the ledgers. Operations owns delivery and acceptance. A network, bank, arbitrator or court may own part of the remedy.
Unknown is a legitimate state
A client can time out after a processor accepted a charge. A stablecoin transaction can be broadcast but not confirmed. A webhook can arrive late. A bank transfer can land without an invoice reference.
The safe response is to mark the outcome unknown, preserve the original attempt and its external references, query the authoritative processor or network, and only create a new attempt once duplicate risk is closed. A retry policy that turns every timeout into a fresh payment duplicates value.
Recourse follows the route
Card disputes are decided by an issuer under scheme rules and evidence deadlines. A refund is a separate adjustment with its own lifecycle. Onchain stablecoin settlement carries no native chargeback, so refund or credit terms have to be written into the contract before the route is enabled.
Deciding what "settled" entitles the buyer to is part of choosing the rail, not an afterthought.
