Built for Composites / Fiberglass owners.
Built for owners running precision and specialty shops - Composites / Fiberglass included. Grounded in real business owners who quote tight tolerances, chase materials, and manage demanding customers.
What Composites / Fiberglass owners ask about
Quoting jobs
Estimating hours, setup, and material without giving away the shop on the first PO.
Skilled trades hiring
Machinists, welders, business owners - where to actually find them and what to pay in your market.
Shop throughput
Bottlenecks, scheduling, and the job that is always in the way of the job that pays.
Customers and POs
Fewer, bigger customers vs. many small ones. Payment terms, deposits, and the customer stringing you along.
Cash and equipment
Financing the next machine, reading your numbers, and knowing when a job is losing money.
Owning the shop
Getting out of the day-to-day, training a foreman, and building a shop that runs without you at the bench.
How the money works in composites / fiberglass
What actually decides your year
Labor-intensive layup with cure times that own your schedule. Mold cost and part yield decide whether a program is worth taking.
- What the customer is buying
- one multi-week build with a deposit
- Business model
- Long custom build
- Your hard ceiling
- Floor space times weeks. A stalled build occupies a spot that could have turned three times.
You are financing someone's project with your own cash unless you structure deposits and progress payments. The build always takes longer than quoted, the customer always adds scope, and the shop space the car or the piece occupies is the real cost nobody prices. Profit comes from staged payments, written scope, and storage rules.
Run the numbers
What a stall actually costs you
One build bay, one year, two ways to run it.
| Bay revenue when it turns | $5,500/week |
|---|---|
| Build that stalls waiting on parts / customer decisions | 6 weeks idle |
| Deposit collected up front | 40% |
| Storage fee after a decision deadline | $75/day |
6 idle weeks × $5,500 = $33,000 of lost bay revenue on one build
Nobody bills for stalls, which is exactly why they happen. A written decision deadline plus a storage fee turns your slowest customers into your fastest ones.
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.
Deposit collected before work starts
30-50%
Filters tire-kickers and funds the parts buy.
Bay turns per year
Know it per bay
The real capacity number in a build shop.
Quoted hours vs actual hours
Within 15%
Custom work hides its overruns in 'we were close'.
Percentage of revenue billed progressively
Most of it
Progress billing is what keeps you out of a line of credit.
Scope changes documented
100%
In custom work, memory is always in the customer's favor.
Where the money leaks
Common profit leaks in composites / fiberglass
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
The forever build
Every shop has one. It is not a customer, it is a mortgage on your best bay. Set a decision deadline, then invoice storage.
02
Quoting a number instead of a range plus a rate
Custom work with a hard number transfers all the risk to you. Quote phases, or quote a rate with an estimate range.
03
Customer-supplied parts on a build
One wrong part stalls the whole car and the customer blames your schedule.
04
Un-billed teardown and discovery
You cannot know the job until it is apart. Sell teardown as its own paid phase with its own deliverable.
05
No storage policy
Finished work sitting on your floor is free warehousing for someone who has your money's worth already.
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
Get paid earlier
- Set a written deposit percentage and stop starting work without it.
- Split every quote into phases with a payment at each.
- Write a storage policy and put it in the contract.
Days 31-60
Close the open builds
- List every build on the floor with its weeks in place and dollars still owed.
- Give each stalled one a decision deadline in writing.
- Sell teardown and discovery as their own paid phase going forward.
Days 61-90
Price the truth
- Compare quoted hours to actual on three finished builds.
- Add the gap to your labor estimate model.
- Set a minimum build size and turn down anything under it.
Hiring ladder
Who to hire, and when
Hire on a trigger, not on a feeling.
Parts and project coordinator
You are on the phone with vendors instead of building
Cheapest hire in a build shop; kills the stall problem directly.
Fabricator / second builder
Backlog exceeds 3 months with full bays
A long backlog with unhappy customers is not growth.
Front-of-house / intake
Customers walk in and interrupt build time daily
Interruptions on custom work cost more than in flat-rate work.
Shop lead
3+ builders
Quality standards on custom work have to live with one person.
Say it out loud
Ending a stalled build
The customer has not made a decision in six weeks and the car is holding a bay.
"I need a decision by the 15th so I can schedule the next phase."
"If we go, I'll invoice the next phase and we're back on the lift that week."
"If you'd rather pause, that's fine - but I'll need it off the floor by the 20th, or storage starts at $75 a day."
"I'm not trying to push you. I have people waiting on this bay and I want your project finished, not parked."
Seasonality
Custom work follows discretionary income and show season. Deposits taken in the fall are what keep the lights on in the spring - sell the winter build slot in September.
