Invoice Dates
{% endembed %}

The insurance companies will not accept an invoice dated before the installation date. If you try to submit an invoice with the dates reversed, it will be kicked back with an error message saying the invoice date is prior to the install date. To correct the invoice date in GlassBiller, click on the invoice date here, and then select the corrected date from the calendar. If the installation date was incorrect, you can simply click here on the date and again select the corrected date from the calendar.
