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

First reminder 3 days after due date, then 7 days, then a call. On the review date you set. If you didn't set one, five business days. 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.

What if they go silent after receiving the proposal?

Assume a process problem before you assume a no. Ask which layer is stuck and offer a thinner version. If you get nothing after a breakup note, archive it. Endless bumps after a proposal train them to wait for a discount.

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 Non-Profit invoice reminder?

Don't imply their mission is inefficient. Help them tell it better. Calling it 'AI-powered' with no description of the system. Don't resend the PDF with 'just bumping this.' Those three mistakes show up constantly in Non-Profit inboxes and they all read as "this was templated."

Friendly reminder: invoice [number]

Body

Hi [First Name],

This is a reminder, not a scare note. Invoice [number] is still open.

I'm writing because a gala, a grant deadline, or a board meeting with a gap in the packet. If this needs to be split across two cost centers, I can reissue it.

Offer to cut scope, split phases, or walk a second stakeholder through one page.

Reply with 'received' if it's already in process so I stop bumping it.

Best,
[Your Name]
[Your Title]
[Your Company]
