Odoo Field Service Australia: Scheduling, Mobile, and GST Invoicing for Trades and Service Businesses
How Odoo Field Service works for Australian trades and service businesses. Scheduling, mobile worksheets, GST invoicing, and inventory in one platform.
By Josh Craig, Director, Auboros ·
If you run a field service business in Australia, you’ve likely stitched together a handful of tools to keep the wheels turning. A job management app here, an invoicing platform there, maybe a spreadsheet for parts. It works, until it doesn’t. Odoo Field Service is one module inside a larger ERP, which means it connects to your inventory, your accounts, and your customer records rather than sitting in its own silo. This post covers what it actually does, where it fits well, and where it has limits.
What does Odoo Field Service actually do?
Odoo Field Service is a job dispatch and management tool. You create tasks, assign them to technicians, track completion, log parts used, and generate invoices, all within the same system your accounts team is already using. The scheduler sees a kanban or calendar view of the whole team. Technicians get a mobile app. Customers get a portal where they can view their job history and invoices.
What makes it different from a standalone tool like Fergus or ServiceM8 is the integration depth. A completed field job can automatically pull the parts used from your warehouse stock, create a draft invoice with GST calculated correctly, and post to your general ledger without anyone re-entering data. That’s the trade-off: you get more integration, but you’re also committed to a full ERP rather than a lightweight app.
Scheduling and dispatch in practice
The scheduling side of Odoo Field Service gives dispatchers four views: kanban, calendar, Gantt, and map. The map view is particularly useful for route planning when you’ve got multiple technicians covering a region. You can drag and drop jobs between team members, set dependencies (don’t go to site B before site A is done), and see everything in hourly, daily, or weekly resolution.
Recurring jobs are also supported natively, so if you have maintenance contracts or regular service visits, these generate automatically on the schedule you set. For businesses running preventive maintenance programs across a portfolio of equipment, this removes a significant amount of manual scheduling work.
Tasks can also be created automatically rather than manually dispatched. A sales order, a helpdesk ticket, a web form, or an email alias can all trigger a new field job. For businesses where the gap between “client signs up” and “job gets booked” is a constant source of friction, this matters.
The mobile experience: what technicians can do on-site
The Odoo mobile app covers the essentials for field technicians. They can view their assigned jobs, update task status, fill in worksheet forms, record parts used, capture customer signatures, and generate a draft invoice on the spot. There’s a built-in timer for tracking labour time, which feeds directly into the invoice.
Worksheets are customisable. You can build templates specific to your service types, so an electrical inspection checklist looks different from a plumbing fault report. Completed worksheets can be sent to the customer as a PDF report at job close-out. If you need pre-built Australian compliance templates covering standards like electrical (AS/NZS 3000), HVAC, heights safety, and fire safety, our FieldPro field service solution includes these out of the box alongside Odoo.
One practical limit worth knowing: Odoo’s mobile app works best with a stable internet connection. Offline mode is available in Odoo v19 for some functions, but it’s not as fully developed as some purpose-built field service apps. If your technicians work in areas with poor mobile coverage regularly, test this carefully before committing. For businesses where offline capability is non-negotiable, our FieldPro app works fully offline and syncs back to Odoo when connectivity is restored.
Parts, inventory, and GST invoicing
When a technician records parts used on a job, those stock movements update inventory in real time. If you’ve set up reorder rules, a low stock alert can trigger a purchase order automatically. For businesses that carry a van stock of commonly used parts, this kind of visibility is genuinely useful.
On the invoicing side, completed field jobs generate a draft invoice that includes labour time (from the timer), parts used (from the worksheet or parts list), and any additional charges. GST is applied according to your tax rules in Odoo’s accounting module, which handles the Australian 10% GST rate and generates invoices in the correct format for ATO compliance. Business Activity Statement (BAS) reporting pulls from the same invoicing data, so there’s no manual export or reconciliation step.
For businesses managing warehouse stock alongside field operations, having both sides inside Odoo means your field team and warehouse team are working from the same inventory data rather than separate systems that get reconciled at month end.
How Odoo Field Service connects to the rest of the business
The integration with Odoo’s other modules is the main reason you’d choose this over a cheaper, simpler field service app. From a single job record, you can see the customer’s full history (quotes, previous jobs, open invoices), the stock levels of parts you’ll need, and the profitability of the project once it’s closed. That kind of connected view is hard to get from a stack of separate apps.
“Most field service businesses we work with are running three or four separate systems. Scheduling in one place, invoicing in another, inventory somewhere else. Odoo isn’t the lightest tool on the market, but once it’s set up properly, the fact that a technician can close a job on their phone and the invoice is ready to approve in accounting ten minutes later is where the real efficiency shows up.”

Odoo Field Service also connects naturally to the CRM module if you’re managing service contracts as part of a sales pipeline, and to the project module if your field jobs are part of a larger project with multiple stages. For businesses already using Odoo CRM, adding field service means your service delivery and customer relationship data live in the same place.
Does Odoo Field Service suit Australian trades businesses?
Construction is Australia’s largest industry by business count, with 462,939 businesses recorded by the ABS at 30 June 2025, and the sector grew 2.2% in the 2024-25 period. Most of them are small. According to the ABS, 91% of construction businesses have fewer than five employees. But plenty of those businesses have real operational complexity: quoting, dispatching, parts tracking, invoicing, BAS reporting. The tools that handle a sole trader at 20 jobs a month stop working well at 200.
Where Odoo fits best in this market: businesses that have outgrown simple job management apps and need their field operations connected to real accounts, real inventory, and proper BAS reporting. If you’re quoting, dispatching, and invoicing all from a single system, you remove a significant amount of double-handling.
Where it may not be the right fit: very small operations (under five people) where the setup cost and learning curve of a full ERP outweighs the benefit, or businesses that need deep integration with Australian-specific trade platforms like Simpro or Fergus. Those tools have more trade-specific features, but they don’t include a full ERP behind them.
For businesses considering Odoo as a full ERP platform, the field service module is included in the Enterprise subscription rather than charged separately. If you’re already running Odoo for accounting, inventory, or sales, adding field service doesn’t add to the per-user cost.

Frequently asked questions
Does Odoo Field Service work offline?
Odoo v19 includes limited offline capability for the mobile app, covering basic task viewing and updates. Full offline functionality, including parts recording and invoice creation, typically requires a connection. If your technicians work in areas with poor mobile coverage, it’s worth testing this in a demo environment before you commit. It’s improving with each release, but standalone trade apps like Simpro handle offline better. If full offline functionality is a firm requirement, our FieldPro solution is built specifically for this and syncs with Odoo when back online.
Can Odoo generate GST-compliant tax invoices from field jobs?
Yes. Odoo’s accounting module includes Australian GST tax rules, so invoices generated from completed field jobs include the correct 10% GST breakdown and meet the ATO’s requirements for a valid tax invoice. These invoices also feed into your BAS reporting automatically. For more on how the localisation works, see our post on Odoo’s Australian localisation for BAS and STP.
What’s the difference between Odoo Field Service and Odoo Project?
They’re related but serve different purposes. Odoo Project is built for multi-task, multi-stage work where the focus is tracking progress and collaboration. Odoo Field Service is optimised for dispatching mobile workers to specific locations, capturing on-site work records, and generating invoices from those records. For a plumbing firm responding to service calls, Field Service makes more sense. For a construction company managing a multi-month build, Project is the better fit. Many businesses use both.
Is Odoo Field Service available on iOS and Android?
Yes, the Odoo mobile app is available on both iOS and Android and supports the Field Service module. Technicians can access their scheduled tasks, fill in worksheets, record parts, capture signatures, and create invoices from their phone or tablet.
How does Odoo Field Service handle subcontractors?
Odoo can assign tasks to external contractors as well as internal staff. The vendor management and purchase order functionality handles subcontractor costs, which can be included in job profitability reporting. The level of visibility into subcontractor time and work completion depends on whether they have access to your Odoo instance, which some businesses allow and others prefer to manage externally.
