Welcome to the Community, @dadshandymancos-.

Let me help and provide information about why you're unable to use envelope to pay bills in QuickBooks Online (QBO).

To begin, you have to first send it to QuickBooks Checking so you can use the bills to pay from an envelope. To move money from an envelope to your QuickBooks Checking account, these are the steps:

1. Select Banking services, then select QuickBooks Checking.
2. In the Envelopes section, select the envelope you want to take money out of.
3. Select Get or Send Money and enter the amount you want to take out of your envelope.
4. In the From field, make sure you selected the correct envelope.
5. In the To field, select your QuickBooks Checking account.
6. Enter the amount you want to take out of your envelope and select Next. Then select Continue when the transfer request finishes.

You can check this handy article for more details: Create envelopes to set your funds aside with QuickBooks Checking.

After posting it in QuickBooks Checking, you can now pay bills with your QuickBooks Checking.

Here's how:

1. Go to Banking Services, then select QuickBooks Checking.
2. Select Pay bill.
3. Follow the prompts to schedule and pay by paper check or ACH.
