The Complete Evolution of Odoo ERP Software 01 to 19
May 18, 2026
The Story Behind Odoo 0 to 16 Million Users
Before we dive into the versions, it helps to understand where Odoo actually came from. In 2005, a Belgian computer science student named Fabien Pinckaers built a small accounting tool for a local business. He called it TinyERP. It was modest — basic invoicing, some inventory tracking — but it worked. And more importantly, it was open-source, which meant the world could help make it better.
That turned out to be a powerful idea. TinyERP grew. Developers in Europe, India, and the Americas contributed modules. The platform evolved into OpenERP in 2010, then became Odoo in 2014 when version 8 launched. Today, Odoo has over 16 million users across 120+ countries, a staff of 4,000+ people, and an annual experience event (Odoo Experience in Brussels) that draws thousands of partners and developers every September.
What made Odoo different — and what still makes it different — is the modular philosophy. You do not buy one enormous ERP system. You activate the apps you need, in the order you need them. Start with Accounting. Add Inventory six months later. Turn on CRM when you hire your first sales team. The platform grows with the business, not the other way around.

The Complete Odoo Version History — Every Version Explained
Let us walk through every major Odoo version chronologically. For each version, you will find the release year, the headline changes, and an honest assessment of whether anyone should still be running it today.
v1–5
TinyERP
2005–2009
End of Support
TinyERP — Where It All Began
Basic accounting and invoicing
Simple inventory tracking
HR and employee management
Python + XML-RPC architecture
Web client introduced in v5
Community-driven module library
These versions established Odoo’s core philosophy: modular, open-source, accessible to small businesses. The platform was rougher around the edges, but the architecture that would eventually support 16 million users was laid right here. Nobody should be running TinyERP today — it is completely unsupported and has not been updated since 2009.
v6
OpenERP
2010–2011
End of Support
OpenERP v6 — The Rebrand and the Web Era
Renamed from TinyERP to OpenERP
New web client (v6.1)
Improved accounting multi-company
Manufacturing (MRP) module matured
Better reporting engine
First e-commerce integration attempts
Version 6 was the platform growing up. The rebrand to OpenERP was partly marketing, partly ambition — Fabien Pinckaers wanted to position it as a serious business platform, not just a small tool. The web client in 6.1 made it genuinely accessible to non-technical users for the first time.
v7
OpenERP
2012–2013
End of Support
OpenERP v7 — The First Modern Interface
Completely redesigned user interface
Chatter and messaging system introduced
Kanban views across all modules
Improved CRM pipeline
Website module foundations
Better mobile responsiveness
Version 7 was genuinely exciting. The new UI made OpenERP feel like a modern product for the first time — Kanban boards, a conversational chatter on every record, a real CRM pipeline. Many developers still fondly remember v7. It attracted a wave of new implementations that helped OpenERP reach hundreds of thousands of users. Completely end-of-life today.
v8
Odoo
2014
End of Support
Odoo8 — The Name That Stuck
OpenERP rebranded as Odoo
Odoo.com website builder launched
eCommerce module introduced
Point of Sale module launched
Community vs Enterprise split begins
New JavaScript-based web framework
Version 8 was a watershed moment. The rebrand to Odoo was not just cosmetic — it signalled a strategic shift toward a complete business suite. The eCommerce module turned Odoo into something genuinely impressive: a single platform where you could manage your warehouse, run your website, and process online orders. This is also the version that introduced the Community / Enterprise split that still defines Odoo today.
v9
Odoo
2015
End of Support
Odoo 9 — The Accounting Overhaul
Accounting module completely rewritten
Multi-currency improvements
Voip integration added
New email marketing module
Improved reporting dashboards
Helpdesk module introduced
Odoo9 fixed the accounting module that version 8 had frankly introduced too hastily. The rewrite made it dramatically more reliable for businesses that needed serious financial management. Many accounting firms first recommended Odoo after v9 cleaned up the double-entry bookkeeping engine.
v10
Odoo
2016
End of Support
Odoo10 — The Manufacturing Leap
Manufacturing module fully rebuilt
Field Service module introduced
Discuss (messaging) module improved
Studio (customization tool) beta
New barcode scanning in Inventory
Improved POS offline mode
Version 10 was the version that made manufacturing businesses take Odoo seriously. The MRP module rebuild was comprehensive — work orders, routing, quality checks, and real-time production floor visibility. Many UAE manufacturing companies in free zones still trace their first Odoo implementation back to v10.
v11
Odoo
2017
End of Support
Odoo11 — Python 3 and a Cleaner Foundation
Migrated to Python 3 (critical for longevity)
IoT Box integration introduced
Accounting — bank synchronisation improved
HR — skills and resumé management
eLearning module launched
Livechat module improved
The Python 3 migration was the most important thing about Odoo11, even if users never saw it directly. Python 2 had reached end-of-life, and staying on it would have eventually killed Odoo’s developer ecosystem. V11 also introduced IoT Box — connecting hardware like printers, scales, and payment terminals directly to Odoo — which opened up serious POS and manufacturing use cases.
v12
Odoo
2018
End of Support
Odoo12 — Speed, Subscriptions, and Sign
Significant performance improvements across all modules
Subscriptions module launched
Sign (e-signature) module introduced
Barcode app fully redesigned
Manufacturing — quality control improvements
HR — attendance and payroll localisations expanded
Version 12 was a reliability release. It was faster, more stable, and introduced the Sign module — which became essential for UAE businesses needing compliant digital contract execution. The Subscriptions module opened up recurring revenue business models within Odoo for the first time.
v13
Odoo
2019
End of Support
Odoo13 — The Web Client Transformation
OWL (Odoo Web Library) JavaScript framework debuts
Spreadsheet module added
Documents module introduced
eCommerce — product variants redesigned
Accounting — bank reconciliation improved
Purchase — vendor price list management
OWL was Odoo’s biggest technical bet in years. By building their own reactive JavaScript framework (instead of depending on third-party libraries), Odoo gained full control over the web client’s performance and future. The Documents module and the improved Spreadsheet integration made Odoo feel more like a real productivity suite, not just a transaction system.
v14
Odoo
Oct 2020
End of Support
Odoo14 — The Modern Era Begins
Completely new UI — cleaner, more modern
Accounting — cash flow statement added
Purchase — landed costs integrated
Barcode scanning improvements
Spreadsheet module expanded
First significant GCC localisations
Odoo14 was genuinely exciting at launch — the cleanest UI Odoo had ever shipped. But it reached end-of-life in October 2023, and as of April 2026, Enterprise customers on v14 whose contracts were renewed after July 2025 are paying a 25% annual surcharge. Odoo.sh will remove v14 hosting entirely in October 2026. If you are still on v14, upgrade immediately.
v15
Odoo
Oct 2021
End of Support
Odoo15 — Refinement and Real Maturity
Spreadsheet — embeddable in dashboards
Inventory — replenishment rules improved
Website — SEO improvements
Marketing — social media scheduling
HR — appraisals redesigned
Knowledge module foundations
Odoo15 was a polishing release — it matured the features that v14 had introduced too quickly. The Spreadsheet module became genuinely useful for financial reporting. V15 reached end-of-life in October 2024. Enterprise customers still on v15 face the same 25% annual surcharge as v14 users. Upgrade to Odoo17 or Odoo19.
v16
Odoo
Oct 2022
Near EOL
Odoo16 — Speed and the Knowledge Module
60–80% faster page loads vs v15
Knowledge module fully launched
Manufacturing — Shop Floor app
Email marketing — A/B testing
Accounting — bank sync improvements
Inventory — putaway strategies expanded
Odoo16 brought the most dramatic performance improvement in Odoo’s history. Pages that took 3 seconds loaded in under a second. The Shop Floor app was a genuine breakthrough for manufacturing — a dedicated tablet interface for production workers that did not require ERP training. However, v16 is no longer one of Odoo’s three covered versions (v17, v18, v19), meaning Enterprise customers now face the 25% annual surcharge.
v17
Odoo
Oct 2023
Supported
Odoo17 — AI Arrives and WhatsApp Enters
First native AI content generation features
WhatsApp Business API integration
New website builder — completely redesigned
HR — flexible work schedules
Manufacturing — flexible BoM components
Accounting — tax closing entries automated
Inventory — product packaging unified
CRM — new pipeline views and enrichment
Odoo17 was the version where AI stopped being a future promise and became a present-day feature. The AI writing assistant appeared in the email editor, the website builder, and marketing tools. More significantly for the GCC market, WhatsApp Business integration was native from day one — making Odoo the first major ERP to offer direct WhatsApp messaging from inside the sales and accounting modules. Odoo17 is still actively supported and is a solid, stable choice for any business.
v18
Odoo
Oct 2024
Supported
Odoo18 — Studio Goes Mainstream and POS Evolves
Odoo Studio — no-code customization expanded significantly
POS — dark mode and kiosk self-service mode
Manufacturing — MRP3 quality control
eCommerce — Stripe link and Google Pay native
HR — payroll localisations for 30+ countries
Accounting — binary field imports in importer
Website — AI page builder improvements
Social media — TikTok integration added
Odoo18 focused on making the platform more self-configurable. Studio — the no-code customization tool that was once only for developers — became genuinely accessible to power users. A business owner could now create custom fields, reports, and workflows without writing a line of code. The POS kiosk mode was particularly well-received by UAE restaurant and retail clients who needed self-service capabilities for busy environments. Odoo18 is fully supported and actively recommended.
v19
Odoo
Sep 2025
Latest
Odoo19 — AI Is No Longer an Add-On, It Is the Platform
AI Agents across all modules — configure without code
Natural language database queries — English or Arabic
Voice-to-text meeting transcripts into CRM records
OCR bank reconciliation — AI matches transactions automatically
Twilio integration — SMS directly from Odoo
Dun & Bradstreet partner autocomplete
Google Places address autocomplete
ESG sustainability module — native reporting
POS — completely rebuilt interface, dark mode, combo deals
Livechat AI agent — generates and routes leads automatically
Gemini AI provider support — use your own account
Mobile-first interface with cached data navigation
Odoo19 is the version that finally delivers on the AI promise. Every previous version had dabbled — AI writing here, a chatbot there. Odoo19 put AI into the infrastructure of the platform itself. You can now describe a workflow in natural language and have Odoo create it. You can ask your database a question in plain Arabic or English and get an answer. Bank reconciliation happens automatically. Leads generate themselves from your live chat. This is Odoo19 — and it is the version every new implementation should start on today.
Still running Odoo16 or older?
You are currently paying a 25% annual surcharge. Transines Solutions handles the full upgrade to Odoo17 or Odoo19 — including custom module migration, data validation, and go-live support.

Odoo Version Support Status — What Is Covered in 2026
This is the most practically important table in this guide. Odoo officially maintains the three most recent major versions at any given time. As of May 2026, those are Odoo17, Odoo18, and Odoo19. Everything else is unsupported — and from April 2026, Enterprise customers whose contracts were renewed after July 2025 pay a 25% annual surcharge for staying on legacy versions.
| Version | Release Date | End of Support | Status (May 2026) | Surcharge (post Jul 2025 renewal) | Our Recommendation |
|---|---|---|---|---|---|
| v1–v12 | 2005–2018 | Varies | Fully deprecated | Surcharge applies | Upgrade immediately |
| Odoo13 | Oct 2019 | Oct 2022 | End of Support | Surcharge applies | Upgrade immediately |
| Odoo14 | Oct 2020 | Oct 2023 | End of Support + Odoo.sh removal Oct 2026 | 25% surcharge | Urgent upgrade required |
| Odoo15 | Oct 2021 | Oct 2024 | End of Support | 25% surcharge | Upgrade this quarter |
| Odoo16 | Oct 2022 | ~Oct 2025 | Not a covered version | 25% surcharge | Upgrade recommended |
| Odoo17 | Oct 2023 | ~Oct 2026 | ✓ Supported | No surcharge | Good — stable and supported |
| Odoo18 | Oct 2024 | ~Oct 2027 | ✓ Supported | No surcharge | Excellent — actively developed |
| Odoo19 | Sep 2025 | ~Oct 2028 | ✓ Latest version | No surcharge | Start all new implementations here |
The 25% Surcharge — What It Really Means
If your Odoo Enterprise annual subscription is AED 40,000, and your contract was renewed after July 2025, you are now paying AED 50,000 — an extra AED 10,000 per year for staying on Odoo16 or below. Divide your upgrade cost by that annual penalty. For most businesses, the upgrade pays back in 12–18 months.
Odoo17 vs Odoo18 vs Odoo19 — Feature Comparison
If you are deciding between the three currently supported versions, here is the direct comparison that matters for businesses implementing Odoo in 2026:
| Feature | Odoo17 | Odoo18 | Odoo19 (Recommended) |
|---|---|---|---|
| AI agents — all modules | ✗ | ◑ Partial | ✓ Full native AI |

Odoo Community vs Odoo Enterprise — The Honest Difference
One of the most searched questions about Odoo is whether the free Community edition is good enough. Here is an honest answer: Community is excellent for developers and for businesses with technical teams that can build and maintain their own modules. For most mid-market businesses — especially in the GCC with compliance requirements — Odoo Enterprise is not optional, it is essential.
| Capability | Community (Free) | Enterprise (Paid) |
|---|---|---|
| Core modules (Accounting, Sales, CRM, Inventory) | ✓ Included | ✓ Included + enhanced |
| UAE FTA e-invoicing localisation | ✗ Not available | ✓ Native |
| Saudi ZATCA e-invoicing | ✗ Not available | ✓ Native |
| WPS payroll (UAE) | ✗ Not available | ✓ Native SIF file |
| Odoo Studio (no-code) | ✗ Not available | ✓ Full access |
| Multi-company management | ✗ Not available | ✓ Unlimited companies |
| Advanced manufacturing (MRP2/MRP3) | ✗ Not available | ✓ Full suite |
| Odoo.sh hosting | ✗ Not available | ✓ Included |
| Mobile app (iOS + Android) | ✗ Not available | ✓ Full mobile app |
| AI agents (Odoo19) | ✗ Not available | ✓ All modules |
| Official Odoo support | ✗ Community only | ✓ Direct Odoo support |
| ESG sustainability reporting | ✗ Not available | ✓ Native (Odoo19) |
| Cost | Free (self-host) | From $24.90/user/month (Odoo Online) |
Our Recommendation for GCC Businesses
If your business is in the UAE, Saudi Arabia, or any GCC country with VAT compliance requirements, you need Odoo Enterprise. The UAE FTA e-invoicing, ZATCA, WPS payroll, and multi-country localisations are all Enterprise-only. The difference in subscription cost is trivial compared to the cost of building these compliance features from scratch on Community.

Frequently Asked Questions — Odoo Versions
What is the latest version of Odoo?
As of May 2026, Odoo19 is the latest stable version, officially released on September 18, 2025 at Odoo Experience 2025 in Brussels. Odoo19 is the first version with full native AI integration across all modules. It is supported by Odoo until approximately October 2028. Odoo20 is expected around September 2026.
What are the key features of Odoo19?
Odoo19’s headline features include: built-in AI agents across all modules configurable without code, natural language database queries in any language (including Arabic), OCR-powered automated bank reconciliation, Twilio SMS integration, WhatsApp improvements, a completely rebuilt POS interface with dark mode and self-service kiosk, native ESG sustainability reporting, Google Places address autocomplete, Dun & Bradstreet partner data, mobile-first interface with cached navigation, and AI-powered live chat lead generation. It is supported until 2028.
Which Odoo version should I use in 2026?
New Odoo implementations in 2026 should start on Odoo19. It is the most feature-rich, most AI-capable, and most future-proof version available. Businesses already on Odoo17 or Odoo18 can stay on those versions — both are actively supported. Businesses on Odoo16 or below should upgrade urgently to avoid the 25% annual Enterprise surcharge and security exposure.
What is the difference between Odoo Community and Odoo Enterprise?
Odoo Community is free and open-source. It includes core accounting, sales, CRM, and inventory modules. Odoo Enterprise is a paid subscription that adds advanced modules including Studio, multi-company, eCommerce, advanced manufacturing, payroll, Sign, Documents, mobile app, Odoo.sh hosting, AI agents, and all GCC localisations (UAE FTA e-invoicing, Saudi ZATCA, WPS payroll). For GCC businesses, Odoo Enterprise is essential.
How often does Odoo release new versions?
Odoo releases one major version per year, typically in September at the Odoo Experience event in Brussels. Odoo17 launched October 2023, Odoo18 in October 2024, and Odoo19 in September 2025. Each version is supported for approximately 3 years before reaching end-of-life.
Can I still use Odoo16 in 2026?
Technically yes, but it is not advisable. Odoo16 is no longer one of Odoo’s three officially supported versions (currently v17, v18, v19). Enterprise customers whose contracts were renewed after July 2025 now pay a 25% annual surcharge for staying on v16. It also no longer receives security patches. Upgrading to Odoo17 or Odoo19 is strongly recommended.
What modules are available in Odoo19?
Odoo19 includes 50+ modules: Accounting, Invoicing, Expenses, Sales, CRM, Purchase, Inventory, Manufacturing (MRP), HR, Payroll, Recruitment, Project, Helpdesk, Field Service, eCommerce, Website, Point of Sale, Email Marketing, Social Marketing, Sign, Documents, Knowledge, Discuss, Fleet, Maintenance, Quality, Repairs, Subscriptions, Rental, Events, eLearning, Studio (Enterprise), and the new ESG Sustainability module. Plus AI agents across all modules in Odoo19 Enterprise.
What happened to Odoo1, 2, 3, 4, and 5?
Odoo began as TinyERP in 2005, founded by Fabien Pinckaers in Belgium. Versions 1 through 5 were released under the TinyERP name between 2005 and 2009. The platform was rebranded to OpenERP with version 6 in 2010, and then renamed Odoo when version 8 launched in 2014. These early versions are completely end-of-life and unsupported.
What is the upgrade path from Odoo16 to Odoo19?
Odoo provides an official upgrade service at upgrade.odoo.com that migrates databases from older versions to Odoo19. You can upgrade directly from Odoo16 to Odoo19 without upgrading through each intermediate version. Any custom modules or third-party apps must be separately migrated to Odoo19 compatibility. Transines Solutions provides end-to-end upgrade services including custom module migration, data validation, UAT, and go-live support.
When will Odoo20 be released?
Odoo20 is expected around September 2026, following Odoo’s annual release cycle. As of May 2026, Odoo20 is in active development. Businesses on Odoo19 will be able to upgrade when it is released. Early signals suggest Odoo20 will build further on the AI foundation laid by Odoo19, with deeper ESG capabilities and expanded localisations.
