No, there is not a maximum number of invoices with Momenteo. Our plans are based on the number of clients you have. If you just started your career as a lawyer and only have two clients, it is free – even if you send them 30 invoices. If you have dozens of clients, you can choose our Plus plan so that you can send invoices to an unlimited number of clients. As well, we do not take any commission on your payments, unlike other invoicing software.
