How correlation scoring works

When a remittance email is received, either in the body of the email or as an attachment, Cash App first attempts to determine a single “best” remittance total before matching it with a payment. To do this, Cash App evaluates several factors and assigns scores across four categories: the amount (comparison between the payment amount and the remittance total extracted), the email domain (whether the sender’s domain matches the expected customer/payor), the date (how close the remittance date is to the payment date), and the count (the expected number of remittances compared with the number of payments during that time period). These factors combine into an overall correlation score. If the score meets the configured threshold, the system automatically links the payment and remittance. If it does not, the pair is routed for manual review to prevent incorrect or risky automatic matches.
