Release data verified 2026-09-26
Platform & Productivity
- Odoo AIOdoo's AI app embeds assistants and automation inside the ERP: drafting content, enriching records, answering from your documents and filling fields from context — with the big advantage that the data is already there.20 changes in Odoo 20
- Odoo CalendarOdoo Calendar is the scheduling backbone the other apps lean on — meetings on CRM leads, appointment slots, activity deadlines — synchronized two-way with Google and Outlook.11 changes in Odoo 20
- Odoo DocumentsOdoo Documents is the filing layer: inboxes per workspace, OCR on inbound PDFs, and actions that turn a file into a vendor bill, task or signature request — where paper-handling time actually disappears.9 changes in Odoo 20
- Odoo PhoneOdoo's Phone app brings calling into the CRM: click-to-call from any record, call logging as activities, and VoIP integration so the softphone lives where the customer data is.10 changes in Odoo 20
- Odoo SignOdoo Sign handles e-signatures inside the flows that need them — quotes, HR contracts, NDAs — with templates, signing orders and an audit trail, instead of a round-trip through an external tool.15 changes in Odoo 20
- Odoo SpreadsheetOdoo Spreadsheet is a spreadsheet engine inside the database: cells can hold live pivots of any Odoo data, so the monthly report rebuilds itself instead of being exported and reassembled.30 changes in Odoo 20
- Odoo StudioOdoo Studio customizes without code: add fields, tweak views, build simple models and automations from the UI — the right tool for the 80% of changes that never needed a developer.9 changes in Odoo 20
Finance
- Odoo AccountingOdoo Accounting runs invoicing, bills, bank reconciliation, taxes and closing on the same database as sales and inventory, so the ledger is a by-product of operations instead of a re-keying job.45 changes in Odoo 20
- Odoo Online PaymentsOnline Payments is Odoo's payment-provider layer: one integration surface (Stripe, PayPal, Adyen, regional gateways) reused by eCommerce, invoices, subscriptions and appointments.16 changes in Odoo 20
Sales & CRM
- Odoo Point of SaleOdoo Point of Sale is a browser POS that keeps selling offline and syncs back when the line returns — registers, restaurants and self-order kiosks run on the same engine as the webshop's stock and pricing.20 changes in Odoo 20
- Odoo SalesOdoo Sales turns quotations into confirmed orders that drive everything downstream — reservations in inventory, work orders in manufacturing, invoices in accounting — which is why its configuration decides how clean the whole flow runs.27 changes in Odoo 20
Website & eCommerce
- Odoo AppointmentsOdoo Appointments is online scheduling wired to the calendar and CRM: booking pages per resource or team, buffer rules, payments at booking, and every booking a record you can automate on.19 changes in Odoo 20
- Odoo eCommerceOdoo eCommerce is a storefront on top of the ERP rather than beside it: products, prices, stock, taxes and customer accounts are the same records the warehouse and accounting use, so overselling and sync glue disappear.38 changes in Odoo 20
- Odoo WebsiteOdoo Website is a block-based site builder living on the same database as CRM, inventory and events — a form submission becomes a lead and a product page reads live stock, with no middleware.60 changes in Odoo 20
Supply Chain
- Odoo InventoryOdoo Inventory is a double-entry stock system: every move has a source and destination location, which is what makes multi-warehouse, consignment and in-transit stock auditable rather than approximate.22 changes in Odoo 20
- Odoo ManufacturingOdoo Manufacturing runs MRP end to end: multi-level BoMs, routings and work centres, scheduled against material availability and capacity, with actual costs accumulated per manufacturing order.24 changes in Odoo 20
- Odoo PurchaseOdoo Purchase runs procurement from requests to bills: RFQs, vendor pricelists, blanket orders and three-way matching against receipts, driven automatically by reordering rules and MRP.9 changes in Odoo 20
Services
- Odoo PlanningOdoo Planning is shift and resource scheduling: roles, availability and recurring templates produce a published schedule employees see in their portal, with open shifts they can claim.20 changes in Odoo 20
- Odoo ProjectOdoo Project plans and bills work: tasks and milestones feed timesheets, and billing policies (fixed, time & materials, milestones) connect delivery directly to invoicing.8 changes in Odoo 20
