Hi Dan,
Thank for your reply 
I have a few counter questions. Firstly yes, we are planning to create the properties on company level for time between each consecutive stage. Like for example in our case we would have:
→ Time spent between Target to Prospect
→ Time spent between Prospect to Awareness
→ Time spent between Awareness to MQA
→ Time spent between MQA to SAA (Sales Accepted)
→ Time spent between SAA to SQA
→ Time spent between SQA to Customer
Sometimes companies move directly from Target to stages ahead of Prospect. So for that we’ll also have:
→ Time spent between Target to Awareness
→ Time spent between Target to MQA
Sometimes it can directly go to SAA and SQA if its driven by sales:
→ Time spent between Target to SAA (Sales Accepted)
→ Time spent between Prospect to SAA (Sales Accepted)
→ Time spent between Awareness to SAA (Sales Accepted)
→ Time spent between Target to SQA
→ Time spent between Prospect to SQA
→ Time spent between Awareness to SQA
My follow up question to you is how do we exactly do this? → Then, to calculate conversion rates manually, you can use these custom properties in HubSpot’s reporting tools. This means crating custom reports that:
Count companies in each stage during a specific time period
Calculate conversion percentages between stages
Are these two different reports? Also how do you achieve it? Can you give me a step by step solution?
