When i do a invoice to a customer once i email it to them it will automatically come up as paid

We're happy to have you here in the QuickBooks Community, @workerbeescleani. Let's work together to figure out the reason behind your invoices automatically marked as paid in QuickBooks Online (QBO) after sending them to your customers.

If an invoice is showing as paid even when there's no payment received, it's possible that the program is automatically applying adjustment notes to customers' balances. Let's go ahead and verify by following the steps outlined below.

1. Go to the Gear icon and select Account and Settings.
2. Click the Advanced tab.
3. Go to the Automation section and select the pencil icon.
4. Turn off the Automatically apply credits feature.
5. Click Save, then Done.
   

Once done, let's unlink the credit memo from the invoice to correct it. Here's how:

1. Go to Sales and click Invoices.
2. Locate the invoice in question and select Edit.
3. On the upper-right corner of the screen, click the 1 payment made hyperlink and select the date.
4. Go to the Credits section and uncheck the applied credit memo.
5. Click Save and Close.
   

Moreover, QBO provides the necessary tools to personalise your sales forms. Doing so will enhance the appearance of your invoices, which will improve business communication with your customers.

Fill me in whenever you have additional queries regarding invoices. I'm always more than willing to lend you a helping hand. Be safe and have a great rest of the day!
