Multiple Quote Numbering Formats for Different Brands

Note that if you create an invoice for a previous month, it will cause a number duplicate. As the numbering will be reset for the current month but the prefix will be for the previous month.

Yes, I know that. I am now working with Qodo to generate the correct hooks, service classes and metadata configuration to make it work. In theory, it should check the existing numbering and set the auto-incremented value to the next number for that month.
