Add HST number to invoices

How do I add the business HSt number to the client invoices? I cannot find a field within the Letterhead section to add it.

Does it show up on the “Billing” worksheet (in the “Registration details” field")?

It’s likely on any of the invoicing templates but I have the following code at the bottom of my invoice.

{{# CurrentClient.BillingWorksheet.Totals.RegistrationDetails }}{{ CurrentClient.BillingWorksheet.Totals.RegistrationDetails}}{{/ CurrentClient.BillingWorksheet.Totals.RegistrationDetails}}

In your Options Profile, go to return Preparation > Invoicing and enter your tax ID here:

This populates the Registration details on the Billing Worksheet which is included on the Invoice template.

You can use the code @kevin posted to add it to your letterhead or simplify it to {{# CurrentClient.BillingWorksheet.Totals.RegistrationDetails }}{{ . }}{{/ CurrentClient.BillingWorksheet.Totals.RegistrationDetails}}
