Odoo Modules List for Odoo 19 and 20: Every App by Edition and Purpose

Most "Odoo modules list" articles were written for Odoo 15 or earlier, mix apps with features, and never say which edition includes what. This guide lists every Odoo 19 and 20 app by category, edition and purpose. Our Odoo implementation services start with exactly this scoping step.

It is for owners, operations leads and IT managers comparing Odoo apps for a first implementation or an upgrade. If you are new to the platform, read what Odoo software is first, then come back for the list.

What is the difference between Odoo apps and Odoo modules?

An Odoo app is a top-level package with its own menu icon, while an Odoo module is any installable package, including the smaller pieces an app depends on. Every app is a module, but most modules are not apps.

The Apps menu shows apps by default. The Odoo 20 docs on apps and modules explain that you must add the "Extra" filter to see modules too. That filter reveals hundreds of entries: country localizations, connectors, bridges between two apps, and technical glue.

This matters for three reasons:

• Pricing: Odoo charges per user, not per app, so the app count never changes your license. What changes it is the plan, covered below.
• Dependencies: the docs warn that installing some apps "may also install additional apps and modules that are technically required". eCommerce, for example, brings Website and Invoicing with it.
• Uninstalling: the same page says uninstalling apps "also deletes their database records", so test removals on a duplicate database first.

The phrase "Odoo ERP modules" in search results usually means the apps. This list uses "app" for the menu-level packages and "module" for everything else.

How many apps does Odoo have in Odoo 19 and 20?

Odoo has 49 apps on its official all-apps page, about 63 once you add the apps the Odoo 20 documentation treats separately, and 70-plus in a live Enterprise Apps menu that shows connectors. The honest answer depends on what you count.

Count	What it includes	Source
49 apps	Nine categories on Odoo's all-apps page, plus WhatsApp in its menu	odoo.com/page/all-apps
63 apps	Adds Payroll, Attendances, Frontdesk, Lunch, Barcode, Repairs, Shop Floor, Marketing Card, Dashboards, Calendar, To-Do, Data Cleaning, Amazon Connector	Odoo 20 docs and editions page
70-plus entries	Adds DHL, UPS, FedEx and other shipping connectors and payment providers shown as apps	Apps menu of an Enterprise database
Thousands of modules	The "Extra" filter: localizations, bridges, technical modules	Apps menu with Extra filter

Competing lists give figures from 30 to 1,000-plus without saying what they count. Use the 63 figure when you plan a project, because those are the apps a business user will actually open. Our Odoo 20 release notes track 585 changes across 52 of them.

Odoo finance and accounting modules list

Odoo's finance apps cover invoicing, full accounting, expenses, documents, e-signature, spreadsheets and ESG reporting, but only Invoicing and Expenses are in Community. This is where the edition decision bites hardest.

App	Edition	What it does	Who needs it
Invoicing	Community	Invoices, vendor bills, payments, basic journals	Every company
Accounting	Enterprise	General ledger, bank reconciliation, reports, tax returns, localizations	Companies closing their own books
Expenses	Community	Expense claims, approval, reimbursement	Teams with travel or field staff
Payroll	Enterprise	Salary rules, payslips, payroll localizations	In-house payroll
Documents	Enterprise	File storage, OCR on bills, workflows	Finance teams drowning in PDFs
Sign	Enterprise	Electronic signatures on contracts and quotes	Sales, HR, legal
Spreadsheet	Enterprise	Live spreadsheets and dashboards on Odoo data	Finance and management reporting
ESG	Enterprise	Carbon and sustainability reporting	Firms with ESG disclosure duties

The Odoo editions page marks Accounting as Enterprise only, which confuses many new users. On the Odoo forum, one asker argued the page must be wrong because invoices create ledger entries anyway.

The best answer explained that Community includes Invoicing as the basic form of accounting, with more unlocked by the "Show Full Accounting Features" group. Another reply on Odoo 18 Community was blunter: "you will need add-ons for reporting and other functionality".

Odoo sales, CRM and POS modules list

Odoo's sales apps run from lead to cash: CRM, Sales and Point of Sale are free in Community, while Subscriptions, Rental and the Amazon Connector need Enterprise. Most companies start here.

App	Edition	What it does	Who needs it
CRM	Community	Pipeline, leads, activities, forecasts	Any team with a sales cycle
Sales	Community	Quotations, orders, pricelists, online signature	Every company that sells
Point of Sale (Shop)	Community	Retail checkout, offline mode, loyalty, receipts	Shops and showrooms
Point of Sale (Restaurant)	Community	Tables, kitchen display, split bills, tips	Restaurants, cafes, bars
Subscriptions	Enterprise	Recurring plans, renewals, churn, MRR reports	SaaS, memberships, contracts
Rental	Enterprise	Rental orders, pickup and return, late fees	Equipment and vehicle rental
Amazon Connector	Enterprise	Sync Amazon orders and deliveries with Sales	Marketplace sellers

CRM and Sales are the two apps most often chosen under the One App Free plan. Pick one, and dependencies such as Contacts and Discuss come free with it.

Odoo supply chain modules: inventory, manufacturing and purchase

Odoo's supply chain apps include Inventory, Manufacturing, Purchase, Maintenance and Repairs in Community, with Barcode, Quality, PLM and Shop Floor reserved for Enterprise. Product companies usually need five or more of these together.

App	Edition	What it does	Who needs it
Inventory	Community	Warehouses, routes, lots and serials, reordering, valuation	Anyone holding stock
Purchase	Community	RFQs, purchase orders, vendor pricelists, receipts	Anyone buying goods
Manufacturing	Community	Bills of materials, manufacturing orders, work orders	Makers and assemblers
Shop Floor	Enterprise	Tablet view for operators, work order control panel	Factories with workstations
Quality	Enterprise	Control points, checks, alerts	Regulated or high-scrap production
PLM	Enterprise	Engineering change orders, BOM versions	Firms with frequent design changes
Maintenance	Community	Equipment, preventive and corrective requests	Plants with machines
Barcode	Enterprise	Scanner-driven receipts, picking, counts	Busy warehouses
Repairs	Community	Repair orders on sold or returned products	After-sales and service centers

Odoo lists Manufacturing as Community but marks its "Shopfloor, Control Panel, Scheduling" line as Enterprise, so a plant that wants tablets on the floor needs the paid edition.

Repairs is missing from the editions table, but the Odoo 20 Repairs docs cover it, and the repair module ships in Odoo's open-source code.

Odoo website, eCommerce and marketing modules list

All six Odoo website apps are in Community, and so are Email Marketing, SMS Marketing, Events and Surveys, while Social Marketing and Marketing Automation need Enterprise. This is the most generous category for Community users.

App	Edition	What it does	Who needs it
Website	Community	Drag-and-drop builder, SEO tools, multi-language	Any company with a website
eCommerce	Community	Online shop, cart, payment providers, delivery	B2C and B2B online sellers
Blog	Community	Articles, tags, comments	Content marketing teams
Forum	Community	Q&A communities with gamification	Product communities, support
Live Chat	Community	Website chat, chatbots, ratings	Sales and support teams
eLearning	Community	Courses, quizzes, certifications	Training providers, onboarding
Email Marketing	Community	Mass mailings, templates, A/B tests	Anyone sending newsletters
SMS Marketing	Community	SMS campaigns via IAP credits	Retail and appointment-heavy firms
Events	Community	Registration, tickets, booths, event pages	Trade shows, webinars
Surveys	Community	Questionnaires, scoring, live sessions	HR, customer feedback
Marketing Card	Community	Personalized shareable image cards	Event and referral campaigns
Marketing Automation	Enterprise	Multi-step workflows triggered by behavior	Teams nurturing leads at scale
Social Marketing	Enterprise	Post scheduling and streams for social accounts	Brands on several networks

eCommerce depends on Website and Invoicing, which Odoo's pricing FAQ uses as its own example. If eCommerce is your one free app, you get those two free as well.

Odoo HR modules list

Odoo's HR apps include Employees, Recruitment, Time Off, Attendances, Fleet and Lunch in Community, with Payroll, Appraisals, Referrals and Frontdesk in Enterprise. The Light User license changes the math for large workforces.

App	Edition	What it does	Who needs it
Employees	Community	Records, departments, skills, contracts	Every company with staff
Recruitment	Community	Job posts, applicants, interview stages	Growing teams
Time Off	Community	Leave types, allocations, approvals	Every company with staff
Attendances	Community	Check-in and check-out, kiosk mode, overtime	Hourly or shift-based teams
Fleet	Community	Vehicles, contracts, fuel, odometer	Firms with company vehicles
Lunch	Community	Meal ordering from vendors	Offices with catering
Payroll	Enterprise	Salary structures, payslips, localizations	In-house payroll teams
Appraisals	Enterprise	Review cycles, goals, feedback	HR running formal reviews
Referrals	Enterprise	Employee referral programs with rewards	Companies hiring at volume
Frontdesk	Enterprise	Visitor check-in kiosk	Offices and plants with visitors

An employee who only needs payslips, time off or attendance can be a Light User at US$8.90 or Rs 195 a month instead of a full user. Our guide to the Odoo 20 Light User explains who qualifies and the catches in the subscription agreement.

Odoo services and productivity modules list

Odoo's services apps include Project and Timesheets in Community, while Helpdesk, Planning and Appointments are Enterprise, and most productivity apps beyond Discuss, Calendar and To-Do are Enterprise too. Service firms should budget for Enterprise.

App	Edition	What it does	Who needs it
Project	Community	Tasks, stages, milestones, profitability	Agencies, consultancies, internal teams
Timesheets	Community	Time logging; grid view and timer are Enterprise	Billable teams
Helpdesk	Enterprise	Tickets, SLAs, portal, ratings	Support teams
Planning	Enterprise	Shift scheduling; includes Field Service in Odoo 20	Dispatch and shift-based teams
Appointments	Enterprise	Online booking linked to calendars	Clinics, salons, consultants
Discuss	Community	Chat, channels, notifications	Every company
Calendar	Community	Shared calendars, Google and Outlook sync	Every company
To-Do	Community	Personal notes and tasks	Individual users
Knowledge	Enterprise	Internal wiki and article templates	Teams documenting processes
Approvals	Enterprise	Custom approval requests and rules	Companies with formal controls
Phone (formerly VoIP)	Enterprise	Calls from Odoo, recording, transcription	Sales and support teams

Studio	Enterprise	No-code fields, views, reports, automations	Customizing without code
IoT	Enterprise	Printers, scales, scanners, cameras	Shops and factories with devices
Data Cleaning	Enterprise	Duplicate merging, field formatting	Databases with messy contacts

Odoo's documentation notes that "as of Odoo 19.0, the VoIP module has been renamed to Odoo Phone". Timesheets shows how an app can be split: the app is Community, but its grid view, timer and validation features are Enterprise.

Which Odoo modules are Community and which are Enterprise only?

Odoo Community includes roughly 40 apps covering invoicing, sales, stock, manufacturing, purchase, project, website and basic HR, while Enterprise adds about 23 more plus mobile apps, hosting and upgrades. The table sums up the split by area.

Area	Community (free)	Enterprise only
Finance	Invoicing, Expenses	Accounting, Payroll, Documents, Sign, Spreadsheet, ESG
Sales	CRM, Sales, Point of Sale	Subscriptions, Rental, Amazon Connector
Supply chain	Inventory, Purchase, Manufacturing, Maintenance, Repairs	Barcode, Quality, PLM, Shop Floor
Websites and marketing	Website, eCommerce, Blog, Forum, Live Chat, eLearning, Email, SMS, Events, Surveys	Marketing Automation, Social Marketing
HR	Employees, Recruitment, Time Off, Attendances, Fleet, Lunch	Payroll, Appraisals, Referrals, Frontdesk
Services and productivity	Project, Timesheets, Discuss, Calendar, To-Do	Helpdesk, Planning, Appointments, Knowledge, Approvals, Phone, WhatsApp, AI, Studio, IoT

The editions page also lists Enterprise-only items that are not apps: mobile apps for Android and iOS, version upgrades, hosting and functional support. For the full trade-off, including OCA alternatives for Community gaps, read our Odoo Community vs Enterprise comparison.

Enterprise pricing is per user, not per app. On the Odoo pricing page, US Standard is US$31.10 per user a month billed yearly (US$24.90 in the first year) and Custom is US$61.00 (US$49.00 first year). In India the figures are Rs 725 and Rs 1,350. Both plans include all apps.

What changed in the Odoo modules list in Odoo 20?

Odoo 20 keeps the same app families as Odoo 19 but merges Field Service into Planning, moves the AI app onto Odoo's own IAP credits, and adds hundreds of smaller changes across 52 apps. Nothing you rely on in Odoo 19 disappears, but a few menus move.

1. Field Service became part of Planning. The Odoo 20 docs no longer list Field Service as its own app. Odoo Online got this in version 19.2; Odoo.sh and on-premise users get it at the Odoo 20 upgrade. Our post on the Odoo 20 Field Service change covers dispatch and worksheets.
2. AI runs on IAP credits. The Odoo 20 AI docs state that AI usage consumes IAP credits, priced at EUR 1 per credit with 20 free. The Odoo 19 option to use your own OpenAI or Gemini key is gone.
3. Agentic AI needs the Custom plan. Odoo's pricing page lists "Odoo Studio / Agentic AI" under Custom, alongside multi-company and the external API.
4. VoIP is Phone. The rename happened in 19.0 and carries into 20, so look for Phone, not VoIP, in the Apps menu.
5. Repairs and Shop Floor are documented as their own apps. They are not new modules, but the separate doc sections are one reason app counts keep climbing.

Our Odoo 20 AI features and IAP credits breakdown estimates what the AI app costs per month for typical teams.

How do you choose which Odoo modules to install?

Choose Odoo modules by starting from the transactions you must record, adding apps only when a real process needs them, and checking the edition and plan each one pulls you into. Fewer apps at go-live means faster training and cleaner data.

1. List your core flows. Quote to cash, procure to pay, make to stock, hire to retire. Each flow maps to two to four apps.
2. Pick the apps for phase one. Most companies start with Sales, Purchase, Inventory and Invoicing or Accounting. Add CRM if sales cycles are long.
3. Check the edition. If your phase-one list includes Accounting, Helpdesk, Planning, Quality or Studio, you need Enterprise.
4. Check the plan. Multi-company, Studio, agentic AI, the external API and Odoo.sh or on-premise hosting require Custom. Odoo's pricing FAQ says installing Studio or adding a company switches you automatically.
5. Map dependencies. Install your list on a trial database and note what else gets installed. Remove anything unplanned before go-live, not after.
6. Defer the rest. Marketing Automation, eLearning, PLM and Knowledge are rarely phase-one apps. Schedule them for month three or later.

A forum user who added Studio during a trial later asked whether it was safe to uninstall. The best answer: back up first, because "you will not be able to get back any data once deleted". Planning the list up front avoids that question.

Our free Odoo App Selector does steps two to five for you. Pick an industry preset or your own apps, set users and hosting, toggle Odoo 19 or 20, and it returns the app list with dependencies marked, an edition verdict and an indicative license cost.

Which Odoo modules does your industry need?

Each industry leans on a different slice of the Odoo modules list, and the edition decision usually follows from two or three must-have apps. The table shows the common starting sets we see.

Industry	Pain or cost driver	Odoo approach	How iVentureTeam helps
Manufacturing	Excel BOMs, no shop floor visibility, scrap	Manufacturing, Inventory, Purchase, Quality, Shop Floor	Model BOMs and routings, set up work centers
Wholesale and distribution	Stock-outs, manual purchase orders	Sales, Purchase, Inventory, Barcode, Accounting	Design warehouse routes, migrate stock
Retail and eCommerce	Separate shop, web and stock systems	Point of Sale, eCommerce, Website, Inventory	Connect channels to one stock ledger
Professional services	Unbilled hours, project overruns	Project, Timesheets, Sales, Helpdesk, Planning	Set up billing rules and time tracking
Field service	Paper worksheets, idle technicians	Planning with Field Service, Inventory, Sales	Configure dispatch and mobile worksheets
SaaS and subscriptions	Manual renewals, revenue leakage	CRM, Sales, Subscriptions, Accounting, Website	Build plans, pricing rules and dunning
Healthcare and clinics	No-shows, paper records	Appointments, Website, Invoicing, Documents, Sign	Configure booking and patient documents
Education	Enrollment chaos, course delivery	eLearning, Events, Website, Invoicing, Surveys	Build course catalogs and enrollment flows

Implementation effort scales with the app count and the edition. Our published Odoo implementation cost ranges run from US$3k to US$9k for a small project of a few apps (4 to 8 weeks) to US$27k to US$150k-plus for large rollouts (12 to 24 weeks). These are ranges, not quotes.

Odoo modules list case study: KMF Technologies

A West African IT services and hardware distributor started with four Odoo apps instead of twenty, and ended its stock-outs within an eight-week phased rollout. KMF Technologies supplies hardware and network infrastructure to institutions across The Gambia.

Before Odoo, products and categories lived in hand-maintained lists, departments could not see each other's data, and customers waited while staff checked stock with each team. Reporting was slow and limited.

We ran a seven-phase implementation covering Sales, Purchase, Inventory and Accounting, configured around KMF's actual workflows. The work included warehouses, stock locations, role-based access, four custom PDF report formats and a chart of accounts localized for The Gambia.

KMF now runs an integrated purchase-to-delivery workflow with live stock across warehouses and fewer entry errors. Its director said: "We went from guessing stock levels to trusting them." Read the full KMF Technologies Odoo inventory implementation case study.

The bottom line on the Odoo modules list

Odoo 19 and 20 give you about 63 named apps, roughly 40 of them free in Community, and the right plan is to pick the four to six that record your core transactions first. Edition follows from your must-have apps; the plan follows from Studio, multi-company, AI and hosting choices.

Treat the list above as a menu, not a shopping cart. Install what a live process needs, check what Odoo installs alongside it, and add the rest in later phases when your team is ready.
