We are a boutique residential apartments developer and are in the hunt for a real estate developer system out there that can integrate with Hubspot and do any of the following:
Inventory Management - Hold the master inventory, book units, reserve, sell, etc
Payment Plans - Have pre-determined payment plans that you can choose at the time of booking a unit
Give accurate financial reports based on cash flow projections based on sold, available and reserved properties
Sales Contracts - to be able to generate Reservation Agreements, Purchase Agreements, etc
I haven't been able to find any real estate developer systems that have existing and publicly accessible integrations with HubSpot, but that isn't to say there isn't a solution out there.
I'll leave the rest of the Community to respond, but may I also suggest reaching out to Bertrand, your channel consultant?
