Does anyone know how I can link to data on an SQL server so that I can create a dynamic sales pipeline with data drawn from estimates actually created?
You could use their API to build a custom solution or use applications like Zapier which allows you to build rules using their API (no coding requred)
Info in API: http://www.smartsheet.com/developer
Didn't see an option from Zapier
I dont use SQL myself so I am not sure if it will work for GC4676 but I saw there was a connection between Smartsheet and SQL Server which is why I suggested it...
use Smartsheet ODBC and upload data via SSIS to SQL Server
