payout
A payout is the transfer of settled funds from the regulated party holding them to the business's or seller's own bank account, on a schedule such as daily, weekly or on demand. In a marketplace, each seller receives their own payout; the platform's fee is paid out to the platform.
Settlement moves money from the card issuer to the acquirer. Payout moves it the last step, to the bank account of the business that earned it. In a simple shop those happen together. In a marketplace or a software platform with many customers they are separate decisions: when each seller is paid, whether refunds and disputes are netted off first, whether a seller can be paid on demand, and what happens when a seller's balance goes negative.
Why it matters to a platform: payouts are the product its sellers notice most. A seller who can see what is coming, when, and why the figure is what it is, stays. A seller who gets an unexplained amount on an unpredictable day calls support or leaves. Payout schedules, statements and the ledger behind them are part of what we mean by payment products.
Who runs the payout: in a regulated-partner model the regulated acquiring partner holds the funds and executes the payout under the platform's rules. Synapto does not hold or move the money. What to watch: the regulated partner will delay payouts on new or higher-risk sellers until verification is complete, so the onboarding flow should say so before the seller is surprised.
