What a complete maintenance file looks like
A list that matches the equipment guide. Work orders tied to serials. Vendor rebuilds with dates. Calibration certificates for CMM and inspection. Crash logs on CNC — see CNC useful life. Press pit and foundation notes on stampers. Barrel and screw history on molders. Resonator hours on lasers.
No CMMS is allowed if you say so. Paper plus invoices still count. A blank history is a finding. “We just run it” is not a remaining-life opinion. Hire the M&E appraiser if the dollars are material.
How equipment age and capex affect value is the valuation companion. Add-backs is where unfunded maintenance dies. This page is the binder.
Fed G.17 utilization 76.0% (July 2026; Source: Fed G.17) plus hero overtime is a near-term earnings story and a medium-term capex story. Deloitte / MI talent pressure (up to 1.9 million roles potentially unfilled; Source: Deloitte / MI) makes neglected iron worse: you cannot staff a crash-prone bay cheaply. BLS May 2025 machinist median $58,750 (Source: BLS) is the labor half of that neglect.
How should deferred capex be priced?
Dollar-for-dollar against cash, or a holdback until the work is done. Split maintenance (keep current output) from growth (add a cell). Crates in the aisle are not maintenance. SBA 7(a) still caps at $5 million (Source: SBA). A buyer who must fund a $400,000 rebuild the week after close is a credit problem and a valuation problem.
There is no national maintenance-percent-of-sales on this site. Prefer plant-level: maintenance plus growth capex divided by sales. Census-sized small shops often under-spend and over-sweat. BizBuySell’s 2.75x SDE median (2021–2025; Source: Iconic recap) already describes many of those files. The chip still matters.
What severe neglect does to the method
It can flip a thin earnings file to the asset floor. A sde-under-1m general CNC cell of 2.0x–3.6x on $300,000 SDE is $600,000–$1.08 million of earnings value. A $220,000 rebuild list plus a written OLV of $1.0 million is already an asset conversation. Do not split the difference.
ISM August 2026 PMI 54.6 (Source: ISM) does not rebuild a spindle. A busy book on tired iron is how past-due backlog and scrap show up together.
| Record | Healthy signal | Deal consequence |
|---|---|---|
| Spindle / cycle hours | Logged, plausible | Missing = condition discount |
| Crash history | Disclosed, repaired | Hidden = trust + cash chip |
| Rebuild invoices | Dated, serial-matched | “Soon” = holdback |
| Calibration | Current | Lapsed = quality finding |
| No CMMS | Disclosed + paper trail | Blank = finding |
| Growth crate in aisle | Labeled unused | Not earnings |
What sellers should gather before the teaser
Serial-matched invoices, the next 24 months of known rebuilds, and an honest overtime footnote. Buyers from buy a manufacturing business will walk the scars. Sellers: sell my manufacturing business. The valuation pillar still picks the cell. Cash is where the chip lands.
How to age a work-order backlog like you age AR
Open work orders by age, by serial, by safety versus cosmetic. A 400-job backlog that is all filters is not a 400-job crisis. A 12-job backlog that is all crashed spindles is. Foot the estimated dollars. That foot is the chip conversation.
If work orders are not aged because they live in a notebook, photograph the notebook and start a list. The finding is the notebook, not the existence of work. Buyers can live with paper. They cannot live with fog.
Rebuilds that are really growth
Replacing a 1998 vertical with a 2024 5-axis is growth dressed as maintenance if the old machine still held the book. Call it growth. Do not hide it inside “keep the lights on.” Age and capex will split the two. This page should give them the invoices to split.
Conversely, a “new” control on a crashed frame may still be maintenance. The appraiser will say. OLV / FMV / FLV is the standard. Your adjective is not.
What a missing crash log does to trust
It tells a buyer the rest of the file may be missing too. OTD and scrap and job cost will be read more skeptically. A disclosed crash with a rebuild invoice is cleaner than a perfect story. QoE firms know the difference.
Sellers who want a clean room should start the log now and still disclose the prior fog. Dating a log to last Tuesday and claiming five quiet years is a finding.
The equipment guide plus this file plus a written OLV is the iron packet. Do not stage the photos without the packet.
How to turn a notebook into a chip list without pretending you have a CMMS
Number the last year of vendor invoices by serial. Photograph the notebook pages that mention crashes. Ask the second-shift lead which machines they baby. Ask the programmer which control they will not run lights-out. Those four inputs will produce a better chip list than a blank CMMS login.
Foot the list in two columns: keep-current-output and growth. A new 5-axis that replaces a still-capable vertical is growth. A spindle that must be rebuilt so the current book can ship is maintenance. Sellers blur the two because growth sounds like a story. Buyers un-blur them because cash is cash.
Give the list to the M&E appraiser if the dollars are material. Remaining life in a CIM that contradicts the appraisal is a credibility problem. Remaining life in a CIM with no appraisal is a brochure. Jason Taken will tell you when to spend the appraisal fee. He will not write the remaining life.
A missing crash log is not a small omission. It tells the rest of diligence to pull harder on scrap, on OTD, and on job-cost tails. Disclose the fog and the invoices you do have. Dating a perfect log to last Tuesday fools no one who has bought a shop before.

A close-week maintenance packet that keeps cash arguments in one folder
Put the reconciled machine list, the serial-matched invoices, the crash notes, the next twenty-four months of known rebuilds, and the overtime footnote in one folder. Name the folder so a lender, a QoE analyst, and an M&E appraiser can find it without a tour guide. Shops that scatter those files across email threads pay for the scatter in exclusivity.
Write a one-page cover that foots keep-current-output dollars versus growth dollars. If the owner was the millwright, say so on that cover. The next owner buys that labor whether or not you like the sentence. BLS medians are a floor for trades, not a millwright package, and not a reason to hide the seat.
If the packet is empty, say it is empty. A blank history is a finding you can price. A perfect log dated last Tuesday is a finding you cannot. Buyers who have purchased a tired bay already know the difference. Give them the invoices you have and the fog you still have. That honesty keeps a Main Street file sellable in the published SDE cell even when the iron is tired.
Do not stage hero photos without this packet. Photos without serials and invoices become arguments. Arguments become chips. Chips become a second price. The packet is how you keep one price.
A closer read on maintenance packet
A buyer who arrives midweek should be able to foot keep-current-output dollars without asking the owner to narrate every invoice. Serial-match the last year. Separate safety work from cosmetic work. Ask the second-shift lead which machines they baby. That conversation is often worth more than a CMMS login nobody used. If the only history is a notebook, photograph it and start the list. Paper is allowed. Fog is not. Give the same packet to the M&E appraiser if the dollars are material so remaining life in a CIM cannot contradict the report. A crate in the aisle is growth, not maintenance. A crashed frame with a new control may still be maintenance. The appraiser will say. Your adjective will not. Disclose the fog you still have. Dating a perfect log to last Tuesday fools no one who has bought a tired bay. Honesty keeps a Main Street file sellable in the published SDE cell even when the iron is tired. Hero photos without this packet become a second price.
What a notebook can prove that a silent CMMS login cannot
Paper is allowed. Fog is not. A notebook with dates, serials, and what was actually done can support a Main Street CNC file in the published SDE cell even when the iron is tired. A CMMS login nobody used since 2022 cannot. Photograph the notebook. Start the list. Give the same packet to the machinery appraiser if the dollars are material so remaining life in a CIM cannot contradict the report.
Separate safety work from cosmetic work. Ask the second-shift lead which machines they baby. That conversation is often worth more than the software. A crate in the aisle is growth, not maintenance. A crashed frame with a new control may still be maintenance. The appraiser will say. Your adjective will not.
Disclose the fog you still have. Dating a perfect log to last Tuesday fools no one who has bought a tired bay. Hero photos without this packet become a second price. Honesty keeps the file sellable. A rebuilt history that starts the week of the teaser does not.
