Can I have a tax point date and an invoice date on a sale invoice in Quickbooks online?

There is not currently a set field for tax point date. You can set invoice date,due date,shipping date automatically on an invoice. If you wanted a tax date added as well you could use a custom field. This adds a custom field box with a name you set up on the invoice, you do have to manually enter the date each time, however. To set a custom field go to the settings cog in the too right of QuickBooks>custom fields>add>save. Any questions let us know,
