Currently, Event Temple doesn't have a dedicated field for tax, HST, or VAT numbers on invoices. However, there are a couple of easy workarounds:
Add It to the Invoice Title
Go to Settings > Invoices
Edit the Invoice Title
Enter your tax number here (e.g., Invoice – HST #123456789)
This will display the tax number at the top of your invoice, directly under the heading.
✅ Note: Only users with the Admin role can update Invoice Settings.
Add It to the Property Address (Use With Caution)
You can also include your tax number in the property’s address field, but keep in mind this will appear wherever the address is used, including documents—so be cautious with formatting and placement.
