What is Odoo? A Complete Guide for Australian Businesses

If you've been researching business software, you've probably come across Odoo. Maybe your accountant mentioned it. Maybe a competitor switched to it. Maybe you're drowning in spreadsheets and someone said "just get an ERP." Whatever brought you here, this guide will give you a straight answer on what Odoo actually is, what it does, and whether it makes sense for your business.

Odoo in one sentence

Odoo is an all-in-one business management platform that covers accounting, inventory, CRM, sales, purchasing, manufacturing, HR, payroll, eCommerce, point of sale, project management, and more — all in a single integrated system.

Think of it as the opposite of having Xero for accounting, HubSpot for CRM, Shopify for eCommerce, Dear Inventory for stock, and Monday.com for projects — all disconnected and none of them talking to each other. Odoo puts all of that into one platform where data flows between modules automatically.

How Odoo works

Odoo is modular. You start with the apps you need and add more as your business grows. The core concept is simple:

• Apps (modules) — Each business function is a separate app: Accounting, Inventory, CRM, Sales, Purchase, Manufacturing, HR, etc. You install only what you use.
• Integrated by default — When you create a sales order, it can automatically generate a delivery order in inventory, create an invoice in accounting, and update the CRM pipeline. No manual re-entry, no CSV imports.
• One database — All your data lives in one place. Your sales team sees the same customer record as your accounts team. Inventory levels update in real time across POS, eCommerce, and warehouse.
• Web-based — Access Odoo from any browser on any device. No software to install on individual computers.

What modules does Odoo have?

Odoo has over 80 official modules. Here are the ones Australian businesses use most:

• Accounting — General ledger, accounts payable/receivable, bank reconciliation, GST/BAS reporting, financial reports. Full Australian localisation with ATO-compliant tax codes.
• Inventory — Stock management, multi-warehouse, barcode scanning, serial/lot tracking, automated reordering rules, FIFO/average costing.
• Sales & CRM — Lead tracking, pipeline management, quotations, sales orders, and reporting. CRM feeds directly into sales which feeds into invoicing.
• Purchase — Purchase orders, vendor management, automated replenishment, receipt and quality checks.
• Manufacturing (MRP) — Bills of materials, manufacturing orders, work centres, routing, quality control, maintenance scheduling.
• Point of Sale — Retail and hospitality POS with integrated payments, including Linkly EFTPOS for Australian terminals.
• eCommerce — Built-in online store or integration with Shopify, WooCommerce, and other platforms.
• HR & Payroll — Employee records, recruitment, appraisals, timesheets, expenses, and as of Odoo 19, native Australian payroll with STP Phase 2.
• Project Management — Tasks, timesheets, Gantt charts, and Kanban boards. Timesheets tie directly to invoicing for service businesses.
• Website Builder — Drag-and-drop website builder with blog, events, and online forms — all connected to your CRM and sales pipeline.

Odoo Community vs Enterprise

Odoo comes in two editions:

• Community — Free, open-source. Includes core modules like Accounting, Inventory, CRM, Sales, Purchase, and Manufacturing. No licence fee, but you handle your own hosting, updates, and support.
• Enterprise — Paid subscription (~$195 AUD/user/year for on-premise, higher for Odoo Online/Odoo.sh). Includes all Community features plus Studio (no-code customiser), Website Builder, full Payroll, Marketing Automation, IoT Box, and official support and updates.

For most Australian businesses, Enterprise is the right choice. The additional modules, automatic updates, and official support more than justify the licence cost. Community is best suited for developers or businesses with strong in-house technical capability.

Hosting options

You have three ways to run Odoo:

• Odoo Online — Odoo hosts everything for you. Simplest option, but limited customisation. No custom modules, no direct server access.
• Odoo.sh — Odoo's own platform-as-a-service. Git-based deployments, staging environments, full customisation. Best of both worlds for most businesses.
• Self-hosted — You host Odoo on your own infrastructure (cloud VPS or on-premise). Maximum control, maximum responsibility.

How much does Odoo cost?

Odoo's pricing has several components:

• Licence fee — Community is free. Enterprise starts at approximately $195 AUD/user/year for on-premise. Odoo Online and Odoo.sh have different pricing tiers that include hosting.
• Implementation — The cost of configuring Odoo for your business, migrating data, and training your team. For Australian SMEs, this typically ranges from $15,000 to $120,000+ depending on complexity.
• Hosting — Free if using Odoo Online (included in subscription). Odoo.sh starts around $250 AUD/month. Self-hosted varies by provider.
• Ongoing support — Optional support contracts with your implementation partner for post-go-live assistance.

Compared to alternatives like SAP Business One ($100K–$500K+), NetSuite ($50K–$300K+), or the hidden cost of running 5+ disconnected SaaS tools, Odoo is typically the most cost-effective option for mid-market businesses.

Australian compliance

This is where many international ERPs fall short. Odoo's Australian compliance has improved significantly:

• GST & BAS — Full GST configuration with 10% standard, GST-free, and input-taxed categories. BAS reporting labels (G1–G11, 1A, 1B) built into the tax report.
• Bank feeds — Basiq (CDR), Yodlee, and SaltEdge supported for automatic bank transaction imports from all major Australian banks.
• Payroll — As of Odoo 19, native Australian payroll with STP Phase 2, PAYG withholding, superannuation, and leave management.
• Chart of accounts — Ships with an Australian default chart of accounts based on the standard business reporting taxonomy.
• Multi-currency — AUD as base currency with full multi-currency support for businesses dealing internationally.

Who is Odoo good for?

Odoo's sweet spot in Australia is growing businesses doing $2M–$100M in revenue that have outgrown basic tools like Xero or MYOB but don't need (or can't afford) enterprise platforms like SAP or NetSuite. Specifically:

• Wholesale & distribution — Businesses managing inventory, purchase orders, and warehouse operations alongside accounting.
• Manufacturing — Companies needing BOM management, production planning, and quality control integrated with their financials.
• Professional services — Firms that need timesheets, project management, and invoicing in one system.
• Retail — Businesses with physical stores (POS), online stores (eCommerce), or both.
• Multi-entity businesses — Companies running multiple brands, locations, or legal entities that need consolidated reporting.

Who is Odoo NOT good for?

Being honest:

• Very small businesses — If you're a sole trader or micro-business that just needs invoicing and bank reconciliation, Xero is simpler and cheaper.
• Businesses with no appetite for change — Implementing an ERP requires effort. If your team won't engage with training and process change, any ERP will fail.
• Highly regulated industries with niche requirements — Healthcare, financial services, and government may need industry-specific systems that Odoo doesn't cover out of the box.
• Businesses already deep in SAP/Oracle — If you've invested heavily in a tier-1 ERP and it's working, switching to Odoo for cost savings alone usually isn't worth the disruption.

How to get started with Odoo in Australia

• Try it yourself — Odoo offers a free trial at odoo.com. Spend an hour clicking around the main modules to get a feel for the interface.
• Talk to a local partner — An Australian Odoo partner (like us) can give you a tailored demo based on your industry and requirements. This is far more useful than a generic trial.
• Start small — You don't have to implement everything at once. Many businesses start with Accounting + Inventory or CRM + Sales, then add modules as they grow.
• Budget for implementation — Odoo isn't plug-and-play for anything beyond basic use. Factor in professional configuration, data migration, and training.

The bottom line

Odoo is the most capable all-in-one business platform available at its price point. For Australian businesses that have outgrown spreadsheets and disconnected SaaS tools, it offers a genuine path to running your entire operation from a single system — accounting, inventory, sales, manufacturing, HR, and more.

The catch is that it needs to be set up properly. A well-implemented Odoo system transforms how a business operates. A poorly implemented one creates more problems than it solves. The software is excellent — the implementation is everything. If you want to explore whether Odoo is right for your business, get in touch for an honest conversation.
