Is it ok to make a memo to self on a invoice?

[AlternativeWeb]

I need to make a note of something that maybe meaningless to my client, but it's something I should remember and have a record of. So, i'm wondering if it's ok to make a memo to my self on a invoice that going to a client?

Nope not at all unless the memo is removable by the time you reach your client.

If you REALLY need to remember something, why not use post its? Just stick it on your invoice and when you are done, remove it.
