CASE FILE №17: THE MACHINE SHOP THAT FOUND $412,000 IT ALREADY HAD
STRATEGY & LEADERSHIPLEADERSHIPSTRATEGY & EXECUTION
9/12/2026
This case file is an illustrative composite, assembled from patterns and results we see repeatedly across owner-operated industrial businesses. The research cited for each intervention is real; the "patient" is representative, not a specific client.
FILE OPENED: APRIL — STATUS: CLOSED, 12 MONTHS
The Patient
Precision machine shop. 24 employees, 19 years old, second-generation owner. $4.1M revenue, respected work, full order book — and a net margin of 4.8% that had drifted down for five straight years while everyone worked harder than ever. Owner's summary at intake: "We're busier than we've ever been and making less than we did in 2019. I don't understand where it goes."
Presenting Symptoms
▸ Quotes priced from a spreadsheet last updated "sometime before Covid," with material costs up ~30% since. ▸ Invoices sent in a month-end batch; receivables aging quietly past 50 days. ▸ Rework running at 6.1% of jobs, absorbed as "the cost of doing precision work." ▸ Two customers = 41% of revenue, terms and prices untouched for years out of fear. ▸ Owner personally quoting every job, approving every purchase, and working 68-hour weeks as the shop's most expensive bottleneck.
Diagnostics — Baseline vs. Month 12
Metric Before After
Net margin 4.8% 11.2%
Days sales outstanding 54 days 38 days
Rework rate 6.1% of jobs 2.3%
On-time delivery 71% 94%
Quote turnaround 4–6 days <24 hours
Owner's work week 68 hours 48 hours
Revenue $4.10M $4.28M (+4%)
Net profit $197K $479K (+$282K)
Total value recovered in year one — profit gain plus one-time cash freed from receivables (~$130K) — approximately $412K, on essentially flat revenue.
The Interventions — in order
01 Repriced from current costs, not 2019's
Rebuilt the quoting model on live material and labor costs; corrected prices with 60 days' notice and a plain-language explanation of what had changed. Two small accounts left; the rest stayed. Effect: roughly half of the total margin recovery, from this alone.
Basis: pricing research — 1% price improvement ≈ 11% operating profit (Price Intelligently); explained increases retain 75% more customers (WinSavvy)
02 Invoiced on delivery + automated the follow-up
Invoices moved from month-end batches to same-day-as-shipment, with an automated reminder sequence behind them. DSO fell 16 days, releasing ~$130K of working capital — the shop's "missing" cash, found in its own receivables.
Basis: Xero — online-payment invoices settle up to 2× faster; Chaser — following up on 90%+ of invoices predicts payment within a week of due date
03 Attacked rework at the root, not the symptom
Every rework incident got a 15-minute root-cause review; the top three causes (an ambiguous drawing-approval step, one worn fixture, a training gap on the newest mill) were fixed permanently. Rework fell from 6.1% to 2.3% — and with it, the overtime and expedite fees it had been generating.
Basis: cost-of-poor-quality research — quality failures typically consume 15–20% of sales; $1 of prevention ≈ $10 of correction
04 Fired the owner from two of his jobs
Quoting was documented, templated, and handed to the senior estimator (with a review threshold for jobs over $25K); purchasing authority under $2K moved to the shop lead. Twenty hours a week returned to the owner — reinvested in the two anchor-customer relationships and a weekly numbers review that now catches drifts in weeks instead of years.
Basis: Gallup — effective delegators grow revenue ~33% faster; leadership studies — owners average 68% of time in daily operations
Examiner's Notes — Transferable Findings
1. The $412K was not created; it was recovered. Every dollar was already inside the business, leaking through prices set in an old cost world, cash parked in receivables, quality failures absorbed as culture, and an owner doing $18/hour work at the most expensive desk in the building.
2. Sequence mattered: pricing first (biggest lever, fastest effect), cash second (funds patience for the rest), quality third (compounds monthly), delegation last (locks it all in place).
3. Nothing here required talent the shop didn't have in year one. It required measurement, courage on one letter, and twelve months of a weekly review that nobody was allowed to cancel. File closed.
