Thanks for joining this conversation, @travsirocz. I can provide steps that will surely help you include your customer's phone number when printing the invoice form.

In QuickBooks Online (QBO), when you create a custom field you also have to enable the Print on form option so it will appear on the printed sales form. Here's how to do it:

1. Log in to your QBO company and select the Gear icon.
2. Then, click the All Lists option.
3. Next, select Custom fields.
4. Locate the custom field for your customer's phone number and click the Edit button.
5. From the All Sales forms section, turn on the Print on form option.
6. Once done, click Save.

Then, let's check if the custom field for your customer's phone number will appear on the printed invoice. Please refer to these steps:

1. Select the +New button and choose Invoice.
2. Enter the necessary details.
3. Click the Customize option to choose the correct invoice template.
4. Once done, select the Print or Preview button.
5. Click Print or Preview. From there, check if you can see the custom field for your customer's phone number.

In case you'll need to review all the invoices you've recorded for a specific period, you can run the Invoice List report. Let me guide you how:

1. Open your QBO account and go to the Reports menu.
2. From the search bar, enter Invoice list and click the report to open.
3. You can also customize the report to filter the details you need to see.
