Why it matters
Understanding settlement helps merchants plan cash flow and understand fees.

The architecture
Card rails: authorization + capture. Settlement T+1 to T+3.
ACH: batch-processed. Slower but cheaper.
Crypto: on-chain confirmation. Minutes to hours depending on chain.

How it works end to end
Fees: card 2-3%, ACH cents, crypto varies. Merchants weigh fees against speed and finality.
Chargebacks: card payments can be reversed weeks later. ACH also. Crypto usually final.
Reconciliation: match authorized tokens to captured funds. Discrepancies indicate fraud or errors.
