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 apology on LinkedIn instead of email?

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 Construction apology?

How should a apology to a Construction CTO change for after an invoice?

Neutral and factual. Warmth without jokes. Don't send long emails during pour days. Be concrete about schedule and docs. Fluffy 'partnership' language wastes a PM's time.

How Construction changes the note

Construction buyers are PMs, estimators, and owners who live in change orders and weather. Don't send long emails during pour days. Be concrete about schedule and docs. Fluffy 'partnership' language wastes a PM's time. A credible proof point in this vertical sounds like: shortened bid-follow-up cycles from 11 days to 4 for a regional GC. Watch the language. Words that land here include bid, RFI, retainage, punch list, GC, change order. Words that work: bid, RFI, retainage, punch list, GC, change order. A thread that ignores bid follow-up that dies, subs who go dark, and paperwork that lags the jobsite reads like every other vendor bump.

Time it for 3 days after due date. A polite reminder a few days after due, then a firmer operational note.
Don't pretend you've run a job if you haven't. They'll test you.
