Get my exact number, free

Estimate only, not a guarantee. It's based on industry estimates that billing mistakes run about 3–5% of 3PL spend; we use a more conservative 2–5% range with 3% as the typical case. Your real number depends on your contract and invoices.

The tedious part

57 pages. 4,812 lines. Who has time for that?

A detailed 3PL invoice can run 50+ pages every month. Checking every line against your contract takes days, so it rarely happens, and small mistakes slip through. We do the tedious work for you.

We find nothing?

You pay $0.

The audit is completely free. No bill, no catch.

We find mistakes?

You keep most of it.

We take a small share, and only after your 3PL pays you back.

Either way, you're never out of pocket.

What we find

Small mistakes that add up to thousands

These are the mistakes we look for on every line.

  • Prices above your contract

    You agreed to $0.50 per item picked. The invoice charges $0.65.

  • Charges billed twice

    The same order or shipment shows up on your bill more than once.

  • Paying for empty space

    Storage billed for pallets and shelves that have nothing on them.

  • Fees you never agreed to

    “Misc” or “special project” charges that aren't in your contract.

  • Extra picking fees

    A case that ships as-is, billed as if every item inside was picked.

  • Minimums you didn't owe

    A monthly minimum fee charged in a month you were well over it.

Why brands use Overrate

All upside, no risk

  • Zero risk

    No upfront cost and no long-term contract. If we don't recover money, you owe nothing.

  • No work for your team

    You send a few files. We do the line-by-line checking nobody has time for.

  • Keeps things friendly

    We write findings as billing corrections, with proof attached. You decide what gets sent.

  • Stops it happening again

    Optional monthly monitoring checks every new invoice for a small flat fee, so mistakes don't creep back.

Your data is safe with us

Your numbers stay private.

Contracts and invoices are sensitive. We treat them that way, and we never share them with third parties.

  • Never sold or shared

    We don't sell your data or share it with third parties.

  • Confidential by default

    Our Terms treat your files as confidential, and we'll sign a mutual NDA whenever you want one.

  • Used only for your audit

    Your files are used to check your invoices, and nothing else.

  • No passwords needed

    We never ask for logins. Exports from your 3PL portal and store are enough.

  • Deleted when you say so

    Ask and we'll delete your files. No questions asked.

  • Benchmarks only if you opt in

    Your rates only join our anonymized benchmarks if you say yes.

Like any online business, we use a few service providers to run Overrate, such as secure hosting and the AI service that reads documents. They may only process your data to provide that service to us, never for their own use. Details are in our Privacy Policy.

Questions

Good questions, straight answers

What does Overrate do?

We check your 3PL (fulfillment warehouse) invoices line by line against your contract and your order data. When we find billing mistakes, we give you the proof and help you get the money credited back.

How much does it cost?

Your audit costs nothing up front. We take a share of the money you actually get back, so if we recover nothing, you pay nothing. After the audit, you can choose optional monthly monitoring for a small flat fee, and we'll keep checking every new invoice so you don't get overcharged again.

Is there a contract?

There's no long-term contract. For the audit, you sign a short agreement that says we're only paid from money we recover for you. Monthly monitoring is a separate plan you can add if you want it.

How accurate is the savings estimate?

It's a starting point based on industry estimates that billing mistakes run about 3–5% of 3PL spend. We use a more conservative range. Your real number depends on your contract and invoices, and the free audit tells you exactly.

Will this upset my 3PL?

We don't accuse anyone. Billing mistakes usually come from billing settings that don't match your contract, and we write them up that way. You stay in control of what gets sent.

How far back can you check?

As far back as your contract allows billing disputes, which is often only recent invoices. That's why it pays to check soon.

What do you need from me?

Your 3PL contract and any rate changes, a few months of invoices, and your Shopify orders export. We'll send you a simple checklist.

Is my data safe?

Yes. Your files are treated as confidential and used only for your check or audit, we never sell your data or share it with third parties, and we delete it when you ask. Want a mutual NDA first? We'll sign one.
