8 Key Features Of Odoo Invoicing

Odoo Invoicing is defined by eight essential features that enable fast, compliant, and scalable invoicing across the entire financial lifecycle. From professional invoice creation to multi-company support and real-time reporting, these capabilities ensure operational efficiency, compliance with Australian standards, and readiness for growth.

1. Fast & Professional Invoice Management

Fast & professional invoice management in Odoo enables businesses to create compliant, clearly structured, and client-ready invoices in just a few steps, minimising administrative friction.

Although Odoo provides a standalone Invoicing app in some setups, invoicing features are fully integrated into the Accounting app once it is installed. This approach offers a centralised workspace that includes tax configuration, journal entries, reconciliation, and financial reporting. The screenshot below illustrates how a new customer invoice is directly generated in Odoo Accounting, with customer and product details automatically populated based on linked records:

• Create and send customer invoices instantly
• Print or email professional-grade invoices
• Include Incoterms® and custom payment terms
• Customise design, layout, and company branding
• Automatically manage invoice sequence numbers.

2. Automated Tax & Localisation for Compliance

Automated tax and localisation in Odoo ensures that every invoice adheres to GST requirements, BAS compliance, and ATO-recognised fiscal structures, out of the box and without manual work. The following screenshot shows that Odoo records the DGST balance as part of BAS reporting by generating a journal entry and auto-balancing tax values across the correct BAS tax grids:

• Configure GST and define tax rounding logic
• Automate tax application via fiscal positions
• Comply with invoicing rules for multiple jurisdictions
• Leverage international tax compliance templates
• Prepare for ATO-aligned BAS reporting

3. Streamlined Refunds & Credit Management

Streamlined refunds and credit management in Odoo give finance teams full control over credit notes, enabling fast reversals, transparent reconciliation, and real-time tracking of outstanding liabilities.

• Create credit notes efficiently
• Track and reconcile refunds in real time
• Set customer credit limits with automated alerts

4. Robust Vendor Invoice & Payment Workflow

Odoo provides a robust vendor invoice and payment workflow by integrating bill receipt, validation, and disbursement processes into a single platform, reducing risk and improving accounts payable efficiency. The screenshot below shows a vendor bill in draft status, ready for review before posting into the accounting ledger:

While these capabilities form the functional core of Odoo Invoicing, their full value is unlocked through strategic integrations. In the next section, we explore how Odoo connects with online payment gateways, Australian banks, and external platforms to deliver seamless automation, faster collections, and compliance with local financial systems.

What Are The Key Integrations That Enhance Odoo Invoicing?

The key integrations that enhance Odoo Invoicing are those that connect the system directly to online payment gateways, Australian bank feeds, and external accounting platforms, transforming invoicing from a stand-alone task into a connected, end-to-end financial workflow. These integrations reduce manual workload, accelerate cash flow, and ensure compliance with ATO and enterprise reporting standards.

The illustration below highlights key integrations with Australian-friendly solution providers for Odoo Invoicing:

1. Connecting with online payment gateways (e.g. Stripe, PayPal)

Odoo Invoicing Tutorial: How To Start With The Basics

Getting started with Odoo Invoicing begins by mastering the system’s foundational workflows - from issuing customer invoices and credit notes to managing vendor bills and setting clear payment terms. These core functions ensure businesses maintain accurate financial records, uphold compliance, and streamline their end-to-end billing operations. See the next illustration to have an overview of the basic steps for first-time Odoo Invoicing users:

To explore Odoo Invoicing in greater depth, refer to the official Odoo Accounting and Invoicing document or tutorial courses that guide you through invoice setup, billing operations, and best-practice configurations - perfect for new users and functional teams seeking hands-on clarity.

1. Issue a customer invoice

Issuing a customer invoice in Odoo creates a journal entry in the Sales Journal that accurately records revenue, GST, and payment terms, while automating the tracking of accounts receivable.

If the Accounting app is installed, most invoicing functionalities are already integrated within it. This unified interface provides finance teams with full control over tax configuration, journal posting, and compliance workflows. In contrast, the Invoicing app, available in some setups, offers a lighter, standalone view focused on basic billing tasks without advanced accounting features.

In this guide, we walk through the process using the Accounting app, as it offers complete visibility across your financial operations and aligns with Australian reporting standards.

• Navigate to the Accounting app and open the Customer > Invoices menu
• Create a new invoice, add product sections, and validate quantities
• Set or confirm the invoice date
• Review journal items and confirm the invoice
• Print or email the invoice directly from the chatter
• Monitor invoice status (draft, posted, paid) from the list view

2. Issue a credit note

A credit note in Odoo is a financial document used to reverse part or all of an original invoice, typically issued for product returns, disputes, pricing errors, or goodwill adjustments. It reduces the customer’s outstanding balance and is automatically reconciled with the related invoice.

You can issue credit notes directly within the Accounting app:

• Open the posted invoice in the Accounting app and click Customers > Credit Note
• Enter the reason (e.g. damaged goods), select the journal, and set a reversal date
• Choose to reverse only or reverse and create a new invoice
• Adjust product lines as needed and confirm the credit note
• Reconcile directly against the original invoice

3. Issue a customer invoice from the sales order

Creating a customer invoice from a sales order in Odoo means converting sales order data into an invoice based on product invoicing policies, reducing manual duplication and errors.

• Create a quotation in the Sales app and confirm it as a sales order
• Use sectioned line items for clarity and grouping
• Generate a draft invoice when invoiceable items are available
• Choose between standard and down payment options
• Confirm and send the invoice - Odoo retains the sales order layout
• Use batch tools to process multiple invoices simultaneously

4. Register a vendor bill

Registering a vendor bill in Odoo refers to capturing and validating a supplier invoice, either from a purchase order or manually, and posting it into accounts payable for future reconciliation.

• Generate a bill from the Purchase app > Purchase Order > Create Bill
• Use auto-complete for vendor details, dates, and product lines
• Edit and confirm the bill to post journal entries
• Register payment, reconcile, and track vendor balances
• Reset to draft or cancel if changes are required

5. Vendor bill digitisation

Vendor bill digitisation in Odoo uses AI and OCR to extract invoice data from PDFs received via email alias or uploads, reducing manual data entry and speeding up approval cycles.

• Upload or scan vendor bills into the Documents app
• Use the scissors tool to split and organise multi-page PDFs
• Launch vendor bill creation with OCR-assisted field recognition
• Autofill vendor, dates, amounts, and tax details
• Detect duplicates, validate, and confirm bills with attached source files

6. Payment terms and conditions

Payment terms and conditions in Odoo define invoice due dates and legal disclaimers, ensuring billing transparency and enforceability with each transaction. These configurations are available under the Accounting app:

• Go to Accounting > Configuration > Invoicing > Payment Terms
• Define schedules with multi-line due dates or percentage splits
• Add plain-text explanations of payment terms on the invoice
• Configure default terms and conditions in Accounting Settings
• Include return policies, legal clauses, or external links
• Track payment delays using the Aged Receivables report

Now that we’ve explored how to operate Odoo Invoicing on a functional level, the next question is one of strategic fit: Is Odoo Invoicing built for the regulatory, financial, and digital needs of Australian businesses? In the next section, we’ll assess Odoo’s localisation for ATO compliance, Peppol readiness, and how it supports Australian business structures out of the box.

Is Odoo Invoicing Right for Australian Businesses?

Yes - Odoo Invoicing is purpose-built to meet the complex compliance, localisation, and operational needs of Australian businesses. From automated GST handling to Peppol eInvoicing and native support for ABA payments and Australian fiscal rules, Odoo provides a complete invoicing platform that aligns with both regulatory expectations and business realities.

1. Australian Taxation and GST Compliance

Odoo Invoicing ensures strict alignment with Australia’s taxation system by embedding GST rules, fiscal-year logic, and BAS-ready features directly into the accounting and invoicing engine. These features make it a practical choice for businesses transitioning from tools like Xero or MYOB, supporting seamless data exchange during upgrade projects, and helping businesses meet ATO audit readiness while maintaining operational continuity.

• Automatically applies GST to invoices and credit notes
• Supports Australia’s fiscal year and default fiscal period settings
• Clean, standardised tax documents with ABN and ACN fields
• Compatible with Anglo-Saxon accounting logic and exchange difference accounts
• Direct support for BAS lodgement, FBT reporting, and GST grouping from Odoo 18 onward
• Smart lock date handling and reconciliation features for audit readiness

2. Peppol eInvoicing Support

Peppol eInvoicing in Odoo allows businesses to meet ANZ government invoicing mandates by generating and exporting structured XML eInvoices, fully compliant with the A-NZ PEPPOL BIS Billing 3.0 format. For teams evaluating whether Odoo 18 or 19 meets these compliance needs, our guide on Odoo Accounting Software explains what’s improved, why it matters, and how finance teams can prepare for Peppol adoption.

• Generate Peppol-compliant XML invoices without third-party add-ons
• Simplify compliance with local eInvoicing mandates
• Roadmap toward native Peppol access point functionality under development
• Future support for Open Banking standards to automate invoice receipt and payments

For businesses preparing to upgrade to Odoo 18, understanding the “why” (e.g. Peppol mandates), “how” (e.g. data migration from Xero/MYOB), and “what” (e.g. localisation features, ATO compliance tools) ensures the transition delivers both operational and regulatory value.

3. Localisation for Australia

Odoo’s localisation goes beyond compliance - adapting invoicing workflows, payment formats, and reporting logic for Australian businesses. This includes EFTPOS and Buy Now, Pay Later options like Afterpay and Humm, and seamless integration with Stripe for real-time online payments. On the vendor side, automated ABA file exports and structured bill digitisation are closely aligned with what’s covered in our Odoo Purchase module, ensuring both sales and procurement flows are tax-compliant and streamlined.

• AU-dedicated hosting improves speed and data residency confidence
• The default chart of accounts is aligned to local product categories
• ABA file export for batch vendor payments
• EFTPOS and Buy Now, Pay Later integration (Afterpay, Humm, Zip Pay)
• AsiaPay and Tyro integrations for AU payment processing
• Internalised payroll and superannuation automation (from Odoo 19)
• Customisable invoice templates with legal disclaimers and payment conditions

For Australian businesses, Odoo Invoicing is not just a capable tool - it’s a regulatory-compliant, scalable, and fully integrated solution that supports long-term financial control and operational agility.
