Can I bill deposits using Cobot?
Deposits are not a explicit feature in Cobot. However, you can create them as charges.
To do so, when you enter a new member, you can go to the member's dashboard/charges/add charge.
Add a description (i.e. security deposit), an amount (whatever you want to hold as a deposit) and the correct tax rate.
Remember that deposits are sensitive charges and you should check your local legislation to find the correct VAT charge and whether deposits can be legally raised in normal invoices.
