When you send a payment request to your team, you can enter custom amounts that team members are required to pay. This is helpful if your team members are required to pay different amounts (e.g. discounted fees, siblings in the same team etc).
When you go to the Payment Requests page in your Teammo account, click '+ New Payment Request' and fill in the form.
In step 2, you select your team members. You can manually change the amounts people are required to pay in the Amount field to the right of each person.
In the scenario below, the team manager requires $10.00 from every team member. However, Sarah Dillon has two children in the same team, so the team manager has doubled the amount requested from her ($20.00).
