Hi @CZangabee
As it read-only property in HubSpot, you won’t be able to update it. A common workaround is to create a custom property on the invoice object or another relevant object and use that to track and update the invoice status from your external system. This custom property can then reflect the status changes as needed.
I hope this will help you out. Please mark it as Solution Accepted and upvote to help another Community member.
