This sets the default Payment terms for your account according to how long a customer has to pay their invoice before it is considered overdue. You can have an overall default Billing Term, and can also set up individual billing terms for different clients.
Default Billing Terms:
To customize these settings in the Web Portal, go to Settings cog > Accounts > Invoices > scroll down to Default Invoice Payment Terms > select the default setting for your preference > Save at the bottom of the page.
In the App, Login > Settings cog in bottom right corner > Invoices > set the Default Payment Terms > Save.
Individual Client Billing Terms:
If you have specific customers who will have different Payments Terms to your Default Payments Terms, you can Customise the Payment Terms for each customer within the customers card in the CRM.
Go to CRM > All Contacts > select the Edit pen for the individual billing contact > scroll down to Billing terms and select the terms for the client > Save.
