To view your statement go to Admin >> Schedule Master Account >> SM Statement. Your Time Sync (i.e. Schedule Master) account can be paid via paper check or electronically. The available electronic methods include credit card, eCheck and PayPal. To make an electronic payment, click on the appropriate payment link, which is located above the date/refresh section.
If you have already entered a credit card and/or bank account into the payment accounts screen, you will see them listed in the payment options. Just verify or edit your payment amount, enter the security code if using a credit card, and click Submit. If you do not have an existing payment option or want to enter a new one, you can click on the links for 'Add Credit Card' or 'Add Bank Account' to add the account.
The payment method entry screen (e.g. the credit card entry screen is pictured below) will have a checkbox for saving the payment method and a checkbox for setting it to your default method for auto-pay. If you do not want your payment method saved or do not want it automatically charged, you can un-check either of these boxes.
Once the new payment method is entered, you should be redirected back to the payment screen with the new option listed. If the new option is not listed for whatever reason, try going to to the statement and then click the payment link again.
