Australia GST Compliance for Odoo: what it covers, what to prepare and which version

Australia GST Compliance fits if you run Odoo 17, 18, 19 or 20 and want the quarterly BAS form, ITC tracking with apportionment, multi-company GST groups and an audit log inside Odoo. It is worth testing it on a copy of your database before deciding. Here is what it covers, what data to prepare and which version to buy.

What it covers according to its documentation

The module's published documentation is a README listing the screens planned for its gallery. According to that README, these are the expected surfaces:

  • A GST registration dashboard with the overall GST status and a rolling turnover widget (rolling turnover).
  • The quarterly BAS form with auto-calculated fields, G1 to G10.
  • ITC eligibility tagging and apportionment management for mixed use.
  • Multi-entity GST group setup with a consolidated view of its members.
  • An immutable audit log with a 5-year retention policy.
  • Further surfaces the README only names: fuel credits, export GST and validation gates.

The same README lists test cases with names such as GST Registration view load, Rolling turnover calculation result and Supply type classification form. If what you need is on that list, the module is aimed at it; if it is not, do not assume it is included.

The 5-year retention is the policy the module describes for its audit log. Do not take it as the legal period that applies to you: check it with your tax adviser.

Published Odoo versions and their price

Australia GST Compliance is published on Odoo Apps for 17.0, 18.0, 19.0 and 20.0. On the listing for each of those versions it costs €9, a one-off payment per version, excluding VAT (listings checked in November 2026).

Pick the listing that matches your database's version: if you run Odoo 18, buy the 18.0 one. You will find them on the Odoo Apps listing.

What changes when you upgrade Odoo

What changes depends on where you bought the module:

  • On the Odoo App Store, each Odoo version is bought there. If you move from 17 to 18, you buy the 18.0 listing.
  • On flexigotech.com with a subscription, the module for new Odoo versions is included.

The subscription is FlexigoTech Cloud's local service. According to the listing, it includes:

  • Monitoring of the module's reference sources, with their alerts and a calendar of their deadlines.
  • Monitoring of the module's health in your database, with alerts.
  • Support with response times: the first response within 1 working day.
  • The service on the staging and test copies of your database.

The local service costs €29/month or €290/year excluding VAT (Pro: €58/month or €580/year). Without a subscription, or with the service suspended, whatever the subscription provides stops; your data stays in your Odoo.

What data to have ready before installing

The columns of the lists the module adds help you prepare your data before you start:

  • GST configuration: Company, Sales GST GL Account, Purchases GST GL Account, GST Payable GL Account and Fuel Credit. Decide which accounts from your chart of accounts you will enter in each.
  • GST groups: GST Group Name, Representative Member, Group ABN, Status and Created. If you will work with a group, have its ABN to hand and know which company you will set as Representative Member.
  • Group members: Group, Company, Effective From, Effective To and Status. Be clear on the dates you will enter in Effective From and Effective To for each company.
  • BAS: Company, Gst Group, Fiscal Year, Fiscal Quarter, Period Start and Period End.
  • GST settings: Enable GST, Representative Member and the G1, G2 and G3 sales accounts.
