Allow payments to be partially or fully reallocated to other invoices without requiring a refund or deletion. Current Behavior When a payment is applied to the wrong invoice, the only option is to delete and refund the payment entirely or add as a customer credit. Requested Behavior Users should be able to select an existing payment and reallocate part or all of it to a different invoice. This would allow corrections to be made internally without impacting the customer-facing record or triggering a refund. Why This Matters This feature would allow teams to correct mistakes quickly, avoid unnecessary refund processing, and maintain accurate invoice records without disrupting the customer experience.
