Some of our eCommerce sales are associated with a contract. The contract specifies the payment terms. To allow customers to self-enroll in a course that is sold as part of a contract, we provide them with a coupon for 100%, which allows them to bypass the payment portal. For these transactions, we need to display a contract number in the transaction report to support our integration with accounting - ensuring that they know the course was really not free, but should be invoiced per the contractual agreement.  Any thoughts on how we could potentially accomplish this?

Thank you,
