How many times should I follow up with a CTO (after an invoice)?

First reminder 3 days after due date, then 7 days, then a call. A polite reminder a few days after due, then a firmer operational note. After that, send a breakup note and archive it. A CTO who wants it will answer a clean close more often than a fifth bump.

Should I apologize for sending an invoice reminder?

No. You can be polite without acting like asking to be paid is a favor. State the facts, offer help if something is blocked, and keep the next step obvious. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

Is it okay to send this invoice reminder on LinkedIn instead of email?

Yes if this CTO is actually active there and the thread isn't about payment details. Keep the LinkedIn version even shorter. Don't paste the full email. One context line and one question is plenty. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

What should I never say in a Legal invoice reminder?

Don't write 'we'll crush opposing counsel.' It's TV, not practice. Calling it 'AI-powered' with no description of the system. Don't threaten, guilt, or bury the amount. Those three mistakes show up constantly in Legal inboxes and they all read as "this was templated."
