Once customers receive email about contract created they can access the Contract Page (either through a link you share or embedded on your website), they simply:

1. Enter their payment details, such as credit card information or bank account details for ACH payments.
2. Review the transaction amount and details.
3. Click on the "Pay Now" button to complete the payment. The transaction is processed securely through RapidCents, and the customer receives a confirmation email once the payment is successful.
