How to add sale and purchased invoice in two extra collum for expiry date and batch number

Thank you for reaching out to us here in the Community, @USGENERICS_ASGME1.

Let me share with you some insights about adding a column in an invoice.

Currently, QuickBooks Online doesn't have the option to add a column. However, we can add a custom field instead. 

Here's how to set up custom fields to appear on sales forms:

1. Go to Settings ⚙.
2. Choose Account and settings under Your Company.
3. Click Sales tab.
4. From the Sales form content section, there are 3 empty fields under the Custom fields header.  Add the fields you want by adding it a title.
5. Tick the Public checkbox if you want the form to appear on printed and delivered forms.
6. Click Save.

For more tips on how to use the Custom Field, you may refer to this article: How to add custom fields to sales forms and purchase orders
