Hello!
We are trying to figure out how we should solve our deal process / integration.
In short:
Customer can have have multiple offers leading in to only one deal.
In our custom app these offers have all unique IDs and also the finals deal have unique ID differing from the offer IDs.
How could should build pipeline & deal to be able to track win/loss rates, generated revenue etc?
I’ve been trying to figure it out for day, but have not been able to solve this issue. 
@samuli3 - This sounds like a good use case for a ‘Offer’ custom object: Create and edit custom objects
If you do not have an Enterprise subscription, and therefore do not have access to Custom Objects, would it be viable to use the Quotes object in HubSpot to capture the information about each of the offers associated to a deal? Resources: Create and share quotes and Quotes API
Hi, @samuli3 ,
The first thing that comes to mind is using the Product library and add line items for every offer. Here’s more information on how they work - Create and manage products
Also, there is an API integration if that’s something you want to link within your custom app - Accounts Dashboard | HubSpot
Would that help?
