HOW TO ADD REFERNCE

In QuickBooks Online, the reference number is labeled as Invoice no. You can use this as your main tracking number, or use the Custom fields feature to set up a separate reference number to appear on the invoice.

Here's how:

1. Go to Settings and select Custom fields.
2. Click Add field or Add custom field if this is your first time creating one.
3. Enter Reference number in the Name field.
4. Select a Data type from the dropdown.
5. Choose a category.
6. In the Select forms section, check the box for Invoice.
7. Ensure that the Print on form option is enabled to display it on printed and delivered forms.
8. Hit Save.

After that, the added field will appear just above the product or service details whenever you create an invoice.
