If you have a SaaS app that allows customers to purchase subscription plans or pay periodic fees at regular intervals (for example. B a monthly invoice), you should consider adding clauses in your legal agreements that discuss the following: The parties accept the payment schedule described in Schedule A (the “payment plan”). The Owing Party undertakes to make payments to the due party in relation to the data in the payment plan. Payment can be made at any time of the date it is due, except in the case of commercial contracts for which payment must be made during normal operating hours. In the absence of an agreement on the place of payment, it is the debtor`s duty to take appropriate measures to search for the creditor and pay the money owed. A debtor is not entitled to a notification or a claim from a creditor without authorization. Other sections of the agreement will be discussed in more detail on every aspect of an account, including billing, refunds, acceptable payment methods, changing your subscription and terminating your account.
