User wants to remove "Billing From" and "Billing To" on invoices.
This can be changed from the company menu > Settings > Global Settings > Billing. You can enable the option to "Show billing through on invoices.' This will replace the 'Billing From' and 'Billing To' dates on the invoices with a 'Billing Through' date. However, there is no option to hide both dates.
The BQE Custom Services team offers the option to create a custom invoice to meet the specific needs of your business and can be contacted for this.
