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 weird to email someone after six months of silence?

Not if you have a new reason and you don't pretend the old thread is still warm. Lead with the trigger, remind them who you are in one line, and make the ask optional. Nostalgia without news is just another cold email with extra steps.

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 Manufacturing invoice reminder?

Don't send a brand video. Send a process. Calling it 'AI-powered' with no description of the system. Don't open with 'it's been a while' and then paste the old pitch. Those three mistakes show up constantly in Manufacturing inboxes and they all read as "this was templated."

How do I email a plant or operations leader well?

Lead with the operational miss: late parts, scrap, changeover time, a quality escape. Ask one question. They don't have a leisurely inbox hour. If you need a meeting, say what decision it unlocks. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

Body

Hi [First Name],

Checking whether invoice [number] is with AP or waiting on something from us.

I'm writing because a line changeover, a customer quality complaint, or a dual-source mandate. Pay here: [link]. Invoice PDF is attached / linked. If the PO, coding, or approver is the blocker, tell me and I'll fix our side today.

Given this is long time no contact, ask if the old problem still exists, or if you should leave it archived.

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

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