Scheduled - The Australian Business Register (ABR) has scheduled system maintenance that will temporarily affect automated ABN validations in Quaderno.
Maintenance Window: 8:00 AM Saturday, 19 September to 8:00 AM Sunday, 20 September 2026 (UTC)
What to Expect: During this window, ABN validation requests will return an "unavailable" status. As a result, the tax reverse charge will not automatically apply to invoices created for new contacts during these hours.
Recommended Action: If you issue invoices to new Australian business customers during this period, please manually review their tax settings or re-validate their ABN once the maintenance window closes to ensure the correct tax treatment is applied.
