I own a small MSP, currently myself and 1 other user. We are looking at possibly using Odoo to replace our Halo PSA, quoting tool, accounting, and some other tools in addition to adding a CRM. Are there other MSP or IT service providers here using Odoo? My primary concerns are;

For billing we bill based on locations, users and computers. Currently we get the user accounts synced from the clients O365 Tenants and the computer counts sync over from our NinjaRMM. Does anyone have some suggestions on how I could accomplish billing this out either through workflow or some kind of integration?

Also for helpdesk we make user of HelpDesk Buttons from Tier2Tickets, they don't have a direct integration with Odoo currently but they can send an email, would I be able to parse out this email to look for company names and what not to assign the ticket to the correct client?
