Indian GST return workflows now support online filing through Odoo's IAP service. Businesses can send and review GSTR-1 summaries, match GSTR-2B data, and view GSTR-3B reports more directly from Odoo, reducing manual filing effort.

GSTR-1: Send and view a summary report
GSTR-2B: Matching
GSTR-3B: View report

Field Service can now automatically create follow-up tasks for regular interventions such as inspections or maintenance. This helps teams avoid missed visits by scheduling the next task based on the previous planned or completion date, with recurrence options controlled from settings.
