Equipment rental invoice audit

Stop overpaying for rental equipment.

We find the overcharges on your equipment rental invoices, dispute them for you, and recover the money. Send us what you have and we'll tell you what we find within 24 hours.

No upfront cost, nothing to install. You keep 80% of anything we recover.

Invoiced monthly rate$4,850
Contracted monthly rate$4,200
Potential discrepancy$650

One line, checked against the agreement that set the rate.

We do that across every invoice you send. Illustrative figures, not a real invoice.

We find overcharges on your equipment rental invoices, dispute them, and recover the money.

  1. 01Find

    We check every charge against the agreement or rate sheet that governs it.

  2. 02Dispute

    We write the challenge, cite the terms that back it, and you approve every word.

  3. 03Recover

    We work it through to a credit or refund. No recovery, no fee.

How it works

The first four are free, findings included. The last one only happens if you want us to chase it.

What we look for

Some of these are clear-cut. Others depend on how your agreement reads or how the job actually ran. Those we flag as potential rather than confirmed, along with what it would take to settle them.

  • Contracted-rate discrepancies
  • Daily, weekly, and monthly rate errors
  • Charges inconsistent with negotiated terms
  • Duplicate or overlapping charges
  • Rental protection plan and damage-waiver discrepancies
  • Delivery and pickup fees
  • Environmental and miscellaneous fees
  • Documented off-rent billing discrepancies
  • Missing credits
  • Other invoice-to-agreement mismatches

The audit is free. After that, you keep 80%.

The findings are yours either way. Take them to your rental company yourself if you would rather. We only charge when you ask us to do the work of getting the money back.

The audit

Free

  • We review every document you send
  • The complete itemised findings
  • What each discrepancy is worth
  • How much is still within a dispute window
  • Yours to keep, whatever you do next

If you want us to pursue it

You keep 80%

of what we recover

  • We write each dispute for you
  • We work the recovery with your rental company
  • Nothing sends without your approval
  • No recovery, no fee

Our 20% comes out of the recovery, never out of pocket. Agreed in writing before we start, and you approve every message before it reaches your rental company.

Rental billing disputes can be time-sensitive.

Most rental agreements give you a window to question a charge after the invoice goes out. How long that window runs depends on your agreement and who you signed it with, so there is no single deadline we can point you to.

An invoice that sat in a folder for a year can still be worth reviewing, but your options narrow the longer it sits. Checking invoices as they arrive is how things get caught while you can still do something about them.

Start with the invoices you've already paid.

Send us recent rental history and the agreements behind it. We will show you what does not add up, including older charges you may no longer be able to claim back. Those still tell you what to watch for next time.

Questions

Anything else? Email audits@equipmentrentalaudit.com and a person will answer.

What should I upload?

Rental agreements, negotiated rate sheets, invoices, off-rent confirmations, credit memos, and related billing records. Send what you have. An invoice on its own tells us something; an invoice plus the agreement that sets its rates tells us a lot more. If we need anything else, we'll ask.

How much does the audit cost?

The audit costs nothing, and the findings are yours to keep whether or not you work with us further. If you ask us to pursue a recovery, you keep 80% of it and we take 20% — deducted from the recovery, never invoiced on top of it. Recover nothing and you owe nothing.

What do I get for free, exactly?

The complete findings: every potential discrepancy we identified, what each one is worth, which documents it came from, and how much still appears to be within a dispute window. That list is yours. Chase it yourself if you would rather, or hand it to whoever handles your invoices. What we charge for is doing that work: writing each dispute, citing the contract terms that support it, and following it through to a credit.

How quickly will I hear back?

We target an initial review within 24 hours after receiving the documents needed to begin. If what you send raises a question we can't answer from the documents, we'll come back to you sooner than that.

Do I need to install software?

No. There's nothing to install, no account to create, and no integration with your accounting system. You upload files through this website and we take it from there.

Will you contact my rental company?

Not without your written authorization, and not without you seeing the message first. When you engage us, you sign a letter of authorization that lets us raise billing questions on your behalf — then we draft each dispute, you approve the wording, and it goes out with you copied. Your relationship with your rep stays yours. This reads as you bringing in a specialist, which is normal.

Which rental companies can you review?

Any of them. We work from the documents you send and the invoices you were billed, so nothing depends on us having a relationship with your rental company. We are an independent service and are not affiliated with any of them.

What happens if you find something?

You get the findings and we walk you through them. From there it is your call: pursue it yourself with what we gave you, or have us do it. If it is us, you keep 80% of what we recover. We write each dispute and work it through, you approve every word before anything is sent, and you can stop at any point.
