Built for Engine Building / Machine Shop shop owners.
Built for specialty and performance shops - Engine Building / Machine Shop included. Grounded in real business owners who quote builds, chase parts, and manage enthusiast customers, not generic web guesses.
What Engine Building / Machine Shop shops ask about
Pricing custom work
Quoting builds, tunes, wraps, and one-off fabrication without eating the overrun.
Build timelines
Setting deposits, deadlines, and the awkward call when parts are 6 weeks out again.
Enthusiast customers
The customer who wants 800 hp for $5k. Saying no, scoping the real build, keeping the relationship.
Specialty techs
Finding a real tuner, diesel tech, or fabricator. Paying them enough to not lose them to the shop down the street.
Marketing to the scene
YouTube, Instagram, local meets, and how much of that actually books work vs. burns weekends.
Warranty and liability
Modified vehicles, tuned engines, insurance conversations, and CYA paperwork that actually holds up.
How the money works in engine building / machine shop
What actually decides your year
Machine time, core availability, and teardown discovery drive everything. Sell teardown and inspection as its own paid phase, always.
- What the customer is buying
- one quoted job against a machine hour
- Business model
- Quoted job shop work
- Your hard ceiling
- Machine hours, and the setup hours that never make a part.
You sell machine time and expertise, and you quote it before you know exactly what it will take. Setup time is the killer on short runs, and a shop that quotes run time without honest setup loses money on every small order. One customer at 40 percent of revenue is not a relationship, it is a risk.
Run the numbers
The shop rate you actually need
One machine, fully loaded, one year.
| Machine + tooling + maintenance | $34,000/yr |
|---|---|
| Operator (loaded) | $68,000/yr |
| Allocated overhead (space, power, software, admin) | $46,000/yr |
| Available hours | 2,000 |
| Realistic utilization | 65% |
($34,000 + $68,000 + $46,000) ÷ (2,000 × 0.65) = $148,000 ÷ 1,300 = $114/hr at break-even
Quoting $95/hour because that is what the shop down the road charges means you lose $19 for every hour that machine runs. Add your target profit on top of $114 and quote from there or do not quote.
Figures are illustrative benchmarks to show the method, not a quote or a promise. Put your own numbers in the same structure - that is the point.
Numbers to watch
The five numbers that tell you the truth
If you only track revenue, you find out about a bad quarter after it is over. These are leading indicators.
Spindle / machine utilization
65-80%
Idle iron is your most expensive asset doing nothing.
Quoted hours vs actual hours
Within 10%
The feedback loop that makes estimating better.
Quote-to-order conversion
25-40%
Low means priced wrong or quoting the wrong customers.
Scrap and rework rate
Under 2%
Rework is paid twice and delivered late.
Revenue concentration
No customer over 25%
The most common way a healthy shop dies suddenly.
Where the money leaks
Common profit leaks in engine building / machine shop
None of these show up as a line item. They show up as a busy year with nothing left at the end of it.
01
Setup buried in run time
Short runs are all setup. Quote setup as its own line and set a minimum order value.
02
No minimum order
Small jobs eat the schedule and the estimator. Set a floor and hold it politely.
03
Free engineering and DFM advice
You are doing the customer's engineering for nothing and it makes their part cheaper to buy elsewhere.
04
Rush jobs at standard price
A rush displaces scheduled work. Price expedite explicitly - 25 to 50 percent - or stop taking them.
05
Material price locked on old quotes
Put a 30-day validity clause on every quote and mean it.
First 90 days
A plan you could start Monday
Three windows, in order. Do not skip the first one - you cannot fix a number you have never measured.
Days 1-30
Know your rate
- Build a real shop rate per machine including overhead and utilization.
- Compare quoted versus actual hours on the last ten jobs.
- Put a 30-day validity clause on every outgoing quote.
Days 31-60
Quote better
- Break setup out as its own priced line.
- Set a minimum order value and an expedite fee.
- Track quote win rate by customer and by part family.
Days 61-90
De-risk and load
- Identify your revenue concentration and start two new customer conversations.
- Track utilization per machine daily and schedule to it.
- Drop or reprice the part families that always run over.
Hiring ladder
Who to hire, and when
Hire on a trigger, not on a feeling.
Programmer / estimator
Quotes are going out late or at night
Slow quoting loses work you would have won.
Second-shift operator
Utilization above 75% on the bottleneck machine
Cheaper than a machine, and proves demand before you buy iron.
Quality / inspection
First-article or customer complaints are rising
Required for regulated customers; cheaper than a recall either way.
Shop supervisor
6+ on the floor
Scheduling and quality need one owner.
Say it out loud
Telling a customer their small job has a minimum
Repeat customer wants five parts.
"I can run five, but our minimum order is $450 because setup is the same whether it is 5 parts or 50."
"If you can take 25, your per-part price drops from $90 to $34."
"Want me to quote both so you can see the difference?"
Seasonality
Job shops follow their customers' capital cycles. Watch for the fourth-quarter budget flush and the first-quarter freeze, and keep two industries in the mix so one downturn does not take the year.
