I wanna show Customer order frequency on invoice

[scentsnsecrets]

Hi, I am looking for an option which can show me the customer order frequency on invoice
as it will help me to see if the customer is the old or new and with the frequency number I can
see that how many he/she has order so far

So, please let me know if someone can help me

Thanks,

If the order notes show up in the invoice, you could use Order Automator to automatically put the customer orders number in the notes section. It's not a default feature but there are free customizations available to do stuff like this.
