What to Do When an Invoice Goes to the Wrong Person at a Company

You sent the invoice 30 days ago. You followed up. Crickets. Then you find out the person you sent it to left the company two months ago, or never handled AP in the first place, and your invoice has been sitting in a dead inbox the whole time.

This is one of the most common reasons invoices get "lost" inside client companies. It's not malice. It's not even disorganization, really. It's just that the person you have a relationship with isn't the person who pays bills, and nobody told you that.

Here's what to actually do when an invoice goes to the wrong person at a company — how to find the right AP contact, re-route the invoice, and reset the payment clock without making it weird.

First, figure out what actually happened

Before you start firing off emails, take 60 seconds to diagnose. There are usually three flavors of this problem:

1. You sent it to your contact (the project manager, the marketing lead, etc.) and they never forwarded it to AP. Super common. They got busy. The email got buried.
2. The AP contact changed at your client. Someone left, got promoted, or the company restructured. The old AP email is dead or unmonitored.
3. The company uses a specific invoice intake system — an AP portal, a dedicated email like invoices@company.com, or a vendor system like Bill.com or Tipalti — and you sent it to a human instead.

Each of these has a slightly different fix. Don't lump them together.

Step 1: Ask your existing contact directly

Your first move isn't to hunt down the right AP person yourself. It's to ask the person you already know.

Here's the email I send:

Subject: Quick check on invoice #1042

Hey [Name] — I sent invoice #1042 over on [date] but haven't seen movement on it. Just want to make sure it's not stuck somewhere.

Two quick questions: 1. Should I be sending invoices to a different email or portal at [Company]? Want to make sure I'm not missing your AP process. 2. Who's the right person on your finance side I should loop in directly going forward?

Thanks!

That's it. Short, no blame, frames it as your problem ("I want to make sure I'm not missing your process") rather than their problem ("you didn't pay me").

About 70% of the time, this email gets you the right contact within a day. Your existing contact will say something like "Oh yeah, send it to Maria — she handles AP" and you're back in business.

Step 2: If your contact doesn't respond, find AP yourself

If you don't hear back within a couple business days, time to do some light digging.

Things to try, in order:

• Check the company website. Bigger companies often have an "accounts payable" or "vendor" page listing exactly where to send invoices. Search "[Company name] accounts payable" or "[Company name] vendor invoice submission."
• LinkedIn. Search the company and filter by titles like "Accounts Payable," "AP Specialist," "Accounting Manager," or "Controller." For smaller companies, "Operations Manager" or "Finance" often doubles as AP.
• Look at the original contract or PO. Sometimes there's a billing address or AP email buried in the boilerplate you signed months ago.
• Check past payments. If they've paid you before, look at the email confirmation, ACH details, or check stub. The remitter info often tells you which team or system processed it.

Once you have a name, send something like:

Subject: Invoice #1042 for [Company] — confirming the right AP contact

Hi [AP Person] — I'm [Your Name], I do [work type] for [Company] and have been working with [Your Contact] on [Project]. I sent invoice #1042 over on [date] but I think it may have gone to the wrong person on your end.

I've attached it again here. Can you confirm receipt and let me know if there's a different submission process I should use going forward?

Thanks!

Notice the framing: you're not accusing anyone, you're confirming a process. That tone matters because you're cold-emailing someone who has no idea who you are and gets a hundred emails a day.

Step 3: Resend, don't restart

Here's where a lot of freelancers mess this up. They figure out the right AP contact, then send a brand new invoice with today's date — which quietly resets the payment clock to Net 30 from now, not from the original send date.

Don't do this. The invoice was already sent. The work was already done. You're not starting over.

Resend the original invoice with the original issue date. In your email, make it clear:

Hi Maria — re-sending invoice #1042 (originally issued [date]) since I learned it was sent to the wrong contact on your end. Net 30 terms based on the original issue date would put this at due on [date]. Let me know if you need anything else from me.

If the original due date has already passed, this is also where you politely note that it's overdue and ask for a timeline. Don't apologize for the re-route — it's not your fault their internal email chain dropped the ball.

Step 4: Update your records so it doesn't happen again

This is the boring step everyone skips, and it's the one that actually fixes the problem long-term.

For every client, you should have:

• The name and email of your day-to-day contact
• The name and email of their AP contact (or the AP intake email/portal)
• Any specific invoice submission requirements (PO number format, required attachments, portal logins, etc.)

Keep this somewhere you'll actually look — a CRM, a spreadsheet, a Notion doc, the notes field in your invoicing tool. Anywhere but your head.

Then make a habit: every 6 months on long-term clients, send a quick "just confirming you're still the right person for invoices" email. People leave companies constantly. The AP contact you had in January might be gone by July, and nobody's going to proactively tell you.

A note on bigger companies and AP portals

If your client is mid-sized or larger, there's a decent chance they use a vendor portal — Bill.com, Coupa, Ariba, Tipalti, something like that. Invoices emailed to a human get ignored or bounced. You have to go through the portal.

If you're not set up in their portal yet, ask. It usually takes a couple of weeks to onboard a new vendor (W-9, ACH details, vendor code, etc.), so the sooner you start that process, the sooner you stop having invoices vanish into the void.

This is also a useful filter when you're scoping new clients. Ask up front: "What's your invoice submission process?" If they hesitate, that's a sign you're going to be doing some unpaid administrative work to figure it out later.

The pattern is bigger than one invoice

If you're a freelancer or small business owner, you've probably had this happen multiple times across multiple clients. It's a structural problem, not a one-off.

The fix isn't to send more reminders to the wrong person. The fix is to know who actually pays the bills before you send the first invoice, and to have a system that follows up on overdue invoices automatically so you catch the "wrong contact" problem in week one, not week six. Tools like automated payment reminder software can handle that follow-up cadence for you so you spot the dead-inbox problem before it becomes a cash flow problem.
