I'll share some details about the Online Bill Pay process.
When you add a vendor, they are set up to be paid via check by default. Going to the Pay Bills page just serves to keep track of the bill payments you've made. You must still process payments in the manner specified by your vendor.
To manually record payments made towards a bill, you can follow these steps:
Go to + New > PayBills.
From the Paymentaccount drop-down, select the account you paid the bill from. For instance, if you paid from your checking account, select checking. Tip: To record payments for the same bill from different accounts (i.e. part by check and part by credit card), or record separate payments on different days. If you select a checking or savings account, you can enter the Starting check no. This is optional.
Enter the paymentdate.
Put a checkmark on the bills you made a payment towards.
In the Paymentcolumn, enter the amount you paid for each bill. Tip: If you have credit with the vendor, you can apply it in the CreditApplied column.
When you're done, click the Schedulepayments online drop-down. Then hit Save, or Saveandclose. Or select Schedule payments online to learn about available payment processing options.
