On the Save window there is an “I’m Offline” option that enables you to save the quote and not attempt to integrate with Kaseya BMS.  

With this option, it is now easy to still save quotes in QuoteWerks even though Kaseya BMS is not available. Please note, any quotes saved while offline will need to be re-opened, linked to a Kaseya BMS contact and saved in order to update Kaseya BMS online.
