Hello there, @Cartman,
I'll provide clarification regarding your concern.
Currently, we're unable to raise the same invoice numbers in QBO with your GoCardless data. The system will still auto-follow the numbering sequence from the last transaction created. I recognize the value of having this feature, as this helps meet your business needs. I'll make sure to take note of this.
I'd still suggest performing the workaround provided by SarahannC above to set your numbering preference.
For the time being, I recommend visiting this link to learn more about our product enhancements: UK Blog.
Lastly, you can check out this website: GoCardless Guide. It contains more details about using the application in QBO, managing mandates, scheduling a direct debit, and reconciling with your bank.
Please let me know if you need anything else. I'll gladly help. Keep safe.
