Settlement

Settlement is when a merchant actually receives payment for transactions they’ve processed. While the mechanics sound straightforward, the settlement waterfall — how much, when, and under what conditions — is where PSPs have significant latitude to affect merchant cash flow.

The Settlement Waterfall

When a PSP settles a merchant:

1. Gross transaction volume for the settlement period is totaled.
2. MDR is deducted (interchange + scheme fees + acquiring margin).
3. Chargeback amounts from disputes received during the period are deducted.
4. Rolling reserve (if applicable) is held back — typically 5–10% of gross volume for a defined period (30–180 days).
5. Net settlement is deposited to the merchant’s designated bank account.

Settlement Timing

Standard settlement timing varies by PSP and market:

• T+1 (next business day): Common for established merchants with low-risk profiles on modern PSP platforms.
• T+2: Standard for many acquiring relationships, particularly international ones.
• T+3 to T+7: Common for higher-risk merchant categories (travel, gaming, subscription) or new merchants without history.
• Instant/same-day: Available from some PSPs (Stripe Instant Payouts, PayPal Instant Transfer) for a fee, typically 0.5–1.5% of the settlement amount.

Rolling Reserve

A rolling reserve is a holdback mechanism where the PSP retains a percentage of each settlement for a defined window (e.g., 10% of gross volume for 90 days). At the end of each window, the held funds are released — meaning at any given time, the merchant has ~10% of their trailing 90 days of volume locked up.

Rolling reserves are standard for high-risk merchants and new accounts. Negotiating them down (or converting to a fixed capped reserve) is one of the highest-value contract negotiations for volume merchants.

Settlement Currency and FX

Most global PSPs settle in USD or the merchant’s local currency. For merchants in Southeast Asia settling cross-border transactions, the FX conversion between transaction currency and settlement currency creates additional costs. The rate applied — and whether it’s marked up above mid-market — is often not disclosed transparently in PSP contracts. Merchants should require explicit FX rate disclosure as a contract term.
