There was a glitch in BlinkBid Online that changed the Invoice Date label to Date Due. To change it back, go to the Settings Document appearance section and edit the Invoice Date field label.
We noticed in this industry that invoices are submitted as “due upon receipt,” but it still takes weeks to get paid. So the Invoice Date that appears on the document is the date the invoice was created, not the due date. You can manually change the Invoice Date in the job window. In an estimate, the date that displays is the date the document was printed.
