If the invoice numbers are not unique then the system will ignore them. In order to ensure that all the MYOB AE generated numbers are unique, we require that MYOB AE be set up to only generate unique bill numbers. To achieve this please navigate to the Maintenance section of MYOB AE and once there find the tick box as indicate below and ensure that it is ticked. ![](https://support.apxium.com/hs-fs/hubfs/How%20To%20Set%20The%20Unique%20Bill%20Number%20in%20MYOB%20AE-jpg-2.jpeg?width=1920&height=1186&name=How%20To%20Set%20The%20Unique%20Bill%20Number%20in%20MYOB%20AE-jpg-2.jpeg) - [Article Navigation Guide](https://support.apxium.com/knowledge/article-navigation-guide?hsLang=en#main-content) - [Article Navigation Guide](https://support.apxium.com/knowledge/article-navigation-guide?hsLang=en#article-navigation-guide) - [Apxium Collect](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#main-content) - [General Features](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#general-features) - [Communications](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#communications) - [Client Experience](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#client-experience) - [Payments, Settlements & Reconciliations](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#payments-settlements-reconciliations) - [Engagement / Proposals](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#engagement-proposals) - [APX Auto (Direct Debiting Invoices)](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#apx-auto-direct-debiting-invoices) - [Instalment Agreements (Non-SOR On Balance Sheet Instalments)](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#instalment-agreements-non-sor-on-balance-sheet-instalments) - [Professional Fee Funding (SOR) - Funded Instalments](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#professional-fee-funding-sor-funded-instalments) - [Reports](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#reports) - [Integrations](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#integrations) - [Onboarding Articles & Other Helpful Guides](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#onboarding-articles-other-helpful-guides) - [Apxium Audit Safe](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#main-content) - [General Features](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#general-features) - [Creating Offers/Subscriptions](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#creating-offers-subscriptions) - [Offer Emails and Documentation](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#offer-emails-and-documentation) - [Accepting / Declining Audit Safe Subscription](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#accepting-declining-audit-safe-subscription) - [Active Audit Safe Subscriptions](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#active-audit-safe-subscriptions) - [Audit Safe Renewal / Rollover](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#audit-safe-renewal-rollover) - [Pricing](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#pricing) - [Others](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#others) - [Apxium Pay My Bill](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#main-content) - [Pay My Bill](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#pay-my-bill) - [Payments and Settlements](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#payments-and-settlements) - [Communications](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#communications) - [APX Auto (Direct Debiting Invoices)](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#apx-auto-direct-debiting-invoices) - [Payrix](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#payrix) - [Client POS - Non Integrated \[North America\]](https://support.apxium.com/knowledge/client-pos-non-integrated-north-america?hsLang=en#main-content) - [Client POS - General Features](https://support.apxium.com/knowledge/client-pos-non-integrated-north-america?hsLang=en#client-pos-general-features) - [APX Capital - Tax Pay for Introducers](https://support.apxium.com/knowledge/apx-capital-tax-pay-for-introducers?hsLang=en) - [APX Capital - Tax Pay For Borrowers](https://support.apxium.com/knowledge/apx-capital-tax-pay-for-borrowers?hsLang=en) [![Apxium Advanced Software Solutions for Accountant](https://support.apxium.com/hs-fs/hubfs/Logos/apxium-logo.png?width=144&height=50&name=apxium-logo.png "Apxium Advanced Software Solutions for Accountant")](http://www.apxium.com?hsLang=en) Copyright © 2025, Apxium HQ
