Yes. You can accept any form of payment that you would like - cash, Venmo, Zelle, PayPal, etc. There is a way to account for it in Motil by the click of a button - i.e. cash transaction.
Additionally, Motil has built a fully compliant payment system so your customers can pay you with credit and debit cards directly via the app as well. That money flows directly into your bank account. This way you have all options when it comes to payments.
