You’ve watched this one unfold. A project manager needs a scissor lift tomorrow. You have several, and every one of them is out on another job or waiting on a part. So someone calls a vendor, a re-rent lands on the project, and now there’s a third-party contract with its own rate, its own billing cycle, and its own return date sitting outside the system that runs the rest of your fleet. The job gets its lift. Your month-end just got more interesting.
That re-rent, or cross hire, is normal. Most contractors do it every week. What is not normal is how little visibility most of them have into what it costs. Equipment tracking tends to work well for the units you own and fall apart the moment a third party enters the picture. This post covers why that happens, what it costs, and what it looks like when the re-rent is handled from the contract instead of from an inbox.
The hidden cost of a re-rent nobody tracks
A typical re-rent touches four people and four places. The coordinator emails the vendor. Accounting raises a PO later, sometimes days later, and often with a different description than the one on the job. The vendor rate lands in a spreadsheet, or in someone’s memory. The delivery date lives in a text thread. The job gets billed at your internal rate, and nobody compares the two numbers until the vendor invoice arrives.
Here is the problem with that sequence. If your job rate for a 26 foot scissor lift is $650 a month and your vendor charges $700 for the same unit, you are paying $50 a month for the privilege of supplying it, and you will not see that until the invoice is coded, which could be 45 days after the lift showed up. Multiply that across a season of re-rents on a busy job and the leak is real, and it never appears as a line item anywhere. It just shows up as a job that finished tighter than it should have.
| 26 ft scissor lift, one month | Rate |
|---|---|
| Job rate you bill | $650 |
| Vendor re-rent rate you pay | $700 |
| Margin on the unit | Minus $50 per month |
| When you find out | ~45 days later, when the invoice is coded |
There are three specific failure points worth naming.
- The PO is disconnected from the demand. When the purchase order is raised in a separate system after the fact, it loses its link to the contract line that created the need. Reconciling vendor invoices back to jobs becomes manual work, and the equipment cost lands on the job late or in the wrong bucket.
- Logistics run on side conversations. Whether the vendor delivers or your team picks up, that decision usually lives outside the system. Trucks show up at the yard nobody planned for, or a unit sits at the vendor for two days because nobody flagged the pickup.
- Margin is invisible until it is history. Without the vendor rate and the job rate on the same screen, there is no way to see, at the moment of commitment, whether the re-rent makes or loses money. You find out after.
What good rental equipment tracking looks like for re-rents
The fix is not more spreadsheets or a tighter email process. The fix is handling the re-rent where the demand originates: on the contract.
When a coordinator sees that a fleet unit is unavailable, the system should offer the alternatives right there. Purchase it and drop ship it to the job, with the full value charged to that project. Or re-rent it from a preferred vendor for a short term gap. Either decision should generate the downstream paperwork automatically, tied to that contract line, so accounting never has to rebuild the link later.
Logistics should be a field on the order, not a phone call. Vendor delivery or self-pickup, chosen at the point of order, with the pickup visible to whoever plans your routes.
And the rate sheet should show both numbers. The rate you charge the job and the rate the vendor charges you, side by side, before the PO goes out. If you have negotiated rates with your preferred vendors, those should populate automatically so the comparison costs nobody any effort.
That is the standard. Most equipment tracking tools, and most ERP rental modules, do not meet it. In a recent review of 15 equipment management platforms, re-rental with a back-to-back PO appeared in only one, and the buy against rent against re-rent margin analysis appeared in none.
Is this worth fixing at your company?
A few questions tell you quickly.
- How many re-rents did your company place last quarter, and could you pull that number in under five minutes? If not, the re-rents are not being tracked as a category of spend.
- When a vendor invoice for a re-rent arrives, how long does it take to match it to a job, and who does that work? If the answer is a person in accounting with a spreadsheet, the PO is disconnected from the demand.
- Can a coordinator see the vendor rate and the job rate together at the moment they place the order? If not, margin on re-rents is a guess until the invoice comes in.
If any of those answers made you wince, the gap is costing you money on every job that re-rents, and it is one of the faster problems to close because it lives in a single workflow.
Rental equipment tracking FAQ
What is rental equipment tracking?
Rental equipment tracking is the process of recording where every rented or re-rented unit is, which job and contract line it is charged to, what it costs per period, and when it comes off rent. Done well, it covers both the fleet you own and the equipment you re-rent from vendors on the same screen.
What is a re-rent or cross hire in construction?
A re-rent, also called a cross hire, is when a contractor rents equipment from a third party vendor to cover a job when its own fleet unit is unavailable, then supplies that unit to the project. The contractor pays the vendor rate and bills the job at its internal rate.
Why do contractors lose margin on re-rented equipment?
Margin leaks when the vendor rate and the job rate are never compared at the moment of commitment. The PO is raised later in a separate system, logistics live in side conversations, and the cost only becomes visible when the vendor invoice is coded, often weeks after the unit arrived.
How should rental equipment tracking software handle re-rents?
It should offer the re-rent as an option on the contract line the moment a fleet unit shows unavailable, generate the back to back PO automatically, capture vendor delivery or self pickup as a field on the order, and show the vendor rate next to the job rate before the PO goes out.
