We recommend adding many to lower conversion rates. - **We recommend** setting a **payment covering percentage** so that slightly underpaid transactions can still count as completed. Example: If set to 5%, a $100 invoice will be treated as paid in full if $95 is received. If a payment is **partially paid** below your threshold, you will receive an email to manually process or refund.
