How an Interac e-Transfer actually moves money
An Interac e-Transfer feels like sending money by email or text, but the email/phone alias and the notification are just messages, the actual money moves as a debit and credit between the two people's banks, with the interbank position settled through Payments Canada's underlying clearing and settlement system.
Canadians, founders, and ops people who use e-Transfer daily and assume the money travels with the email.From a card tap to settlement: the four-party model (Visa as the example)
When you tap a card, an authorization is a real-time check and hold that moves no money; the network switch routes that message and later the clearing records, and only afterward do the banks settle the actual money, typically funding the merchant a day or two later, net of fees.
Founders, product, and ops people who see a card payment as one instant event and don't realize auth, clearing, and settlement are separate.ACH credit vs ACH debit: who pulls and who pushes

A chargeback is the network process for forcibly pulling a disputed card payment back from the merchant to the cardholder; the merchant can fight back by submitting evidence in a step called representment.
Founders, ops, product, and BD who take card payments and want to understand disputes before one lands.How a marketplace pays out its sellers
A marketplace collects the buyer's card payment into its own settlement account, tracks each seller's share on a ledger, and then pushes payouts out to sellers (often by ACH or an instant rail), minus its fees and any held reserves.

Recurring billing relies on a stored mandate or saved payment credential that lets a merchant pull an agreed amount on a schedule, with each pull running as its own authorization and settlement.
