Hi PTCan,
QuickBooks Online is all about organizing and simplifying your books. The numbering system feature is ideal to keep track of your transactions and easily access them when necessary. I'll be happy to share more about this.
At the moment, the automatic numbering system is continuous for numbers and stagnant for letters.
If you'd benefit from additional options in managing the numbering system, feel free to submit feedback directly to our engineers. Your comments are crucial in driving innovation to offer the best QuickBooks experience we can.
I'll be here if you have any further questions. Enjoy your weekend!
