Odoo 20: What You Get Today
The points below come from Odoo’s official release notes, as summarized by a partner.
AI Agents and MCP
Odoo 20 moves AI from suggestions to action. Agents create and update records, including from an uploaded PDF, and connect to your database through MCP. MCP is an open protocol. It lets outside AI tools talk to Odoo without a custom bridge. ecosire
Other AI changes:
- Automated and scheduled actions call agents.
- Users dictate requests by voice.
- Odoo picks the AI model for each task.
- Agent conversations stay stored for up to 30 days.
AI costs extra. All AI features need credits bought through IAP. Budget for this before you roll AI out to a team. ecosire
Offline Mode and Mobile
Users create, edit, archive and delete records without a connection. Warehouse and field teams gain the most. Mobile forms are redesigned for touch, and you share files from your phone into Odoo to create bills, tasks and leads. ecosire
Simpler Access Rights
Odoo 20 removes record rules and places a domain on the access right itself. This change affects every custom module with security rules. Test those modules on a copy of your database before you upgrade. ecosire
Accounting
- Parent accounts replace account groups. Account codes become optional.
- Depreciation models replace asset models.
- Payment labels change. “In Process” becomes “Paid” and “Paid” becomes “Reconciled”.
- One bank transaction splits across several accounts.
- Duplicate bill detection improves and a wizard warns about double payments.
Check any report or export built on the old payment labels.
Inventory and Manufacturing
- Odoo suggests min and max reorder levels from demand history.
- A stock aging report arrives in Moves Analysis.
- Continuous production starts the next operation as soon as some quantity is ready.
- You split a running manufacturing order and finish the rest later.
- Work orders gain Kanban and drag-and-drop Gantt views.
Sales, eCommerce and Point of Sale
- Pricelist rules apply to specific periods or weekdays.
- Commissions follow the amount paid.
- eCommerce adds returns, review requests and cross-sell suggestions.
- POS handles several currencies and several printers.
- POS runs without the Inventory app.
Industry Packages and Localizations
Odoo 20 adds 13 new industry packages and refreshes more than 12 others. These are starting setups. They speed up a rollout but do not replace fitting Odoo to your process. linkedin
Localizations form the largest part of the release notes. Examples include FBR e-invoicing for Pakistan, ZATCA batch processing for Saudi Arabia and a VAT audit file for the UAE. ecosire

What Features to Expect in Odoo 21
Odoo has published no Odoo 21 feature list. Be careful with articles claiming one. Many pre-launch Odoo 20 articles listed AI forecasting and multi-calendar scheduling. Those lists were expectations, not official notes. The same applies here. ksolves
These expectations follow the direction Odoo 20 set:
- Deeper AI agents. Expect more actions, more apps covered and more control over what agents touch.
- Wider MCP use. Expect more tools connecting to Odoo through the protocol.
- More offline coverage. Odoo 20 started this work. More apps should follow.
- More industry packages. Odoo adds a batch each year.
- More localizations. E-invoicing rules keep changing across countries, so expect new entries.
- API changes for developers. Odoo postponed removal of the old RPC services. The removal now sits at Odoo 21.1 or 22. Move integrations to the JSON-2 API now. odoo

- On Odoo 18. You have support to about 2027. Plan the upgrade for 2027 and skip ahead if you want.
