When the Custom SMS feature is enabled, you will be able to choose either 'Email Invoice' or 'Text Invoice' when sending the invoice. If you choose 'Text Invoice,' the “allow customers to pay online” checkbox will be checked and cannot be unchecked.
An SMS text message will be sent from your custom SMS phone number to the customer with the following message: “Invoice due from [COMPANY NAME]. Click the link to review and pay.” It also includes a link to pay the invoice. The customer can then review the Job Summary and enter their credit card information to pay.
