My company too can’t make HubSpot our ‘Hub’ for quoting. We need the flexability of custom properties like you can add to contact, company and deal records.
Custom properties also need to be set as text, monetary value or percentage. Similar to the way excel lets you format a cell.
The price table on the quote also needs to have the option to select what properties (default & custom) are shown.
Then we can make HubSpot our true Sales Hub.
And if we are asking for the world, make a hyperlink available too. We have 8.5x11 sized specification sheets that would be great to link to. Not everyone can put a thumnail image of their product right in the table.
