Hubspot order fulfillment app

Hi fellow indie hackers !

I was thinking of building a Hubspot App that would help order fulfillment.
Currently, for e-commerce like solutions you have no Hubspot integrated app to manage your physical goods orders.

The app would be synchronized to Hubspot to enable within Hubspot to :

• Create new orders for each new Hubspot deal
• Synchronize Hubspot deal with order status
• Connect to shipping plateforms like UPS
• Update the inventory
• Display orders information in the contact or company information

All this would match the Hubspot products.
Would be suitable to any store that sells or rent physical goods. I haven't seen an app like that that is fully integrated to Hubspot.

What do you think ?
