The amount of FNCTION cashback depends on the current portal rate, eligible products, order value, exclusions, and promotional terms. Cashback rates may be a percentage of the purchase or a fixed reward.

**When will my FNCTION cashback appear in my account?**
FNCTION cashback often appears as pending within a few hours or days after a tracked purchase. Processing times vary because the retailer and cashback portal may need to confirm the order.

FNCTION cashback usually becomes payable after the retailer’s return, cancellation, and validation period ends. The exact time depends on the portal’s terms and the type of purchase.

FNCTION cashback may remain pending while the retailer verifies the order, confirms payment, and checks that the purchase was not returned or canceled. Review the portal’s estimated validation period before contacting support.

**Why did my FNCTION cashback fail to track?**
Cashback tracking can fail if cookies are blocked, an ad blocker is active, another coupon or referral link overrides the portal tracking, the purchase is made in a different session, or the order includes excluded items.
