Summary
Please add a setting to block or control partial card payments. Today, if a card has insufficient funds, Toast can auto-accept a partial payment. We need the option to decline partials or at least prompt before accepting them. This was available on our previous system as well.
Why this matters
Customers may not have the remaining balance, and the split makes returns messy.
Customers often want to switch to a different tender entirely.
Each swipe costs us money—on tiny partials we’d rather not run the card at all.
This has led to avoidable frustration at checkout.
What we’re asking for (minimal viable)
Setting: “Allow partial card payments” = On/Off (preferably per location/device/order type).
Prompt option: If On, show a modal when a partial is detected:
Thresholds (nice-to-have): Set a minimum partial amount or percentage to accept.
Auto-void behavior: If a partial is declined or the sale is canceled, automatically void the partial auth.
Benefit
Cleaner customer experience, fewer surprise splits, and lower processing costs on low-dollar partials.
