You have two options to do a make payment in MCA Suite.
1. If you want to add an extra payment at the end of the Billing schedule, increase the num left by one on the Billing schedule page.
2. If you want to hit the merchant twice in a day, create a one time payment. To create a one time payment, press the One Time payment button on the Billing schedule page. Please remember to check "Apply to Deal" if you want the system to track the transaction to increase the amount repaid on the deal.
