How do I follow up on an unpaid invoice without damaging the relationship?

Assume a process issue first. Put the facts up top, offer to fix coding or PO problems, and keep the tone operational. Escalate to the original buyer only after AP has had a fair chance. Rage emails get paid last.

Is it okay to send this thank you on LinkedIn instead of email?

Yes if this procurement officer is actually active there and the thread isn't about long attachments. 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 thank you?

Don't imply their mission is inefficient. Help them tell it better. Trying to go around them to the business owner in a way that's obvious. Don't threaten, guilt, or bury the amount. Those three mistakes show up constantly in Non-Profit inboxes and they all read as "this was templated."

How should donor follow-up sound?

Grateful, specific, and light on pressure. Name the program the gift touched. Ask for a conversation when it's real, not after every newsletter. People give again when they feel remembered, not processed. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

How should a thank you to a Non-Profit Procurement Officer change for after an invoice?

The procurement officer is guarding policy, vendor risk, and negotiated value, so the ask should stay at "the next document or a date for review, not a 'relationship meeting'."
