Question about the client ID number on invoices

As English isn’t my native language I was wondering if the term “ID Number” is what a client expects to see on an invoice?
I was used to seeing the term “customer ID” so I just wanted to double check.

Please excuse my ignorance.

You can change it on Settings > Invoice Design > Invoice Labels.

I know, its just that if I override a label there I kill multi-language support. I just wanted to confirm with a native English speaker that “ID number” is OK to use here.

If you’re self hosting you could change the files in resources/lang/

The label seems ok to me…
