Where Does the Money Go?

A 5-minute walk-through of how Taishan actually makes — or loses — money each month. No accounting knowledge needed.

01The Core Idea

Revenue Is Not Profit

Follow one month of $300,000 all the way down.

Revenue$300,000
The work we completed
Direct Project Costs− $216,000
Materials + direct labour
Gross Profit Remaining$84,000
Gross margin 28%
Monthly Operating Structure− $66,400
Wages, gas, food, rent, insurance…
Actual Company Profit Before Tax
$17,600
Where every dollar goes
Project costs72.0%
Operating expenses22.1%
Company profit left5.9%

The company did $300,000 of work, but only $17,600 was actually left.

02The Monthly Machine

What Does It Cost Just to Keep the Company Running?

These costs happen whether we build $0 or $500,000 of work.

$237,143
At 28% gross margin

Current management estimate — classification should be verified with accounting. If a wage is already inside direct project labour when we calculate the 25–28% project margin, switch it to “Direct project labour” so it is not counted twice.

03The Red Line

How Much Work Must We Complete Before We Make $1?

Company Profit = Revenue × Gross Margin − Operating Expenses

Revenue$300,000
Gross profit$84,000
Operating expenses− $66,400
Net margin5.9%
Break-even revenue$237,143
Healthy profit
$17,600

The first ~$237,143 of monthly production only feeds the operating machine. Only production beyond that begins creating company profit.

05Break-Even By Margin

Margin Changes the Amount of Work We Need to Survive

Low-margin work forces the company to chase more revenue just to stand still.

06Growth Has a Cost

“More Revenue” Is Not Free

  1. 1More revenue
  2. 2More projects
  3. 3More customers
  4. 4More scheduling
  5. 5More trucks / fuel
  6. 6More workers
  7. 7More mistakes / callbacks
  8. 8More management
  9. 9More mental energy

Increasing revenue is one solution — but revenue growth also increases operating complexity.

This is why increasing productivity and margin can sometimes be more powerful than simply adding more projects.

07Three Levers

What Management Can Actually Pull

Lever 1 — Reduce operating expense

Saving $10,000/month means ~$35,714 less production required at 28%.

08Fixed Cost Math

Every Fixed Dollar Must Be Supported By Gross Profit

Required Revenue = Fixed Cost ÷ Gross Margin

09Important

This Is Not About Blaming Employees

An employee does not need to personally install $35,714 of work. Value can be created indirectly.

Managing crews
Preventing mistakes
Increasing installation speed
Sales
Scheduling
Purchasing
Reducing downtime
Quality control
Allowing another employee to produce more

The economic question is simple: does this position create or enable enough gross profit to justify its cost?

10Productivity Gap

If One Part Doesn’t Carry Its Weight, Another Part Must

Example only. Monthly fixed cost $10,000 at 28% margin requires $35,714 of enabled production.

Scenario A — cost supported
$35,714

Directly or indirectly enables enough production. The cost pays for itself.

Scenario B — gap appears
Gap other teams must cover$15,714

If one part of the operating structure doesn’t carry its economic weight, another part has to carry it.

11Crew-Day Economics

The Same Crew Does Not Produce the Same Value Every Day

The crew’s daily labour cost stays almost identical. Their economic output does not.

12Same Crew. Same Day.

Small Job vs Large Job

Same workers, same truck, same 8–10 hour day, similar daily labour expense.

Small job
Contract
$2,000
Advanced that day 100%
Production value / 产值
$2,000

Even perfect execution cannot produce more — the whole contract is only $2,000.

Large job
Contract
$50,000
Advanced that day 15%
Production value / 产值
$7,500

≈ 3.75× more production value

Bigger project
Contract
$100,000
Advanced that day 15%
Production value / 产值
$15,000

≈ 7.5× the $2,000 job

13Important

Production Progress Is Not Profit

$15,000 of contract progression does not mean $15,000 of profit — materials and direct costs still exist.

Metric 1 — Production value per crew-day
Contract value × estimated completion progress
Metric 2 — Gross-profit production per crew-day
Estimated gross profit × estimated completion progress

This one matters more — gross profit is what pays company overhead.

15Opportunity Cost

A Profitable Job Can Still Be a Poor Use of a Crew-Day

A $2,000 job might make money. That does not automatically mean sending a major production crew there was the best decision.

Option A

Crew spends the whole day on a small project.

$2,000
Option B

Same crew progresses a larger project.

$10,000
Production opportunity difference
$8,000

This is not automatically lost profit — it is production capacity that was used differently.

16Mobilization

Workers Can Be Busy Without Producing

Every transition consumes labour hours without installing any work.

  1. 1Crew leaves yard
  2. 2Drives to job
  3. 3Unload equipment
  4. 4Setup
  5. 5Work
  6. 6Cleanup
  7. 7Load equipment
  8. 8Drive again
  9. 9Setup next project

Busy is not the same as productive. Only installed work creates production value.

$250,000 a month feels like a big company. Under this cost structure it is barely above survival.

19Why Wages Become Hard To Pay

Cash Problems Are a Sequence, Not One Mistake

23Survival vs Healthy

Three Zones

“Healthy” is not a universal accounting fact — management chooses the target.

Below break-even

The company is consuming cash.

Break-even to small profit

Survives, but no protection.

Healthy profit

Reserves, clearing liabilities, reinvestment.

26Management Questions

Six Questions

01

Are we pricing projects at sufficient margins?

02

Does every fixed operating position create or enable enough economic value?

03

Are our strongest crews spending their days on the highest-value production?

04

Are small jobs and mobilization consuming high-value crew capacity?

05

Can the existing structure produce significantly more without significantly increasing overhead?

06

Are we measuring success by revenue — or by gross profit and cash actually retained?

The problem is not necessarily that we don’t have enough work.

The question is whether our existing people, time and money are producing enough gross profit.

There are only so many crew-days in a month.
There is only so much management capacity.
There is only so much money in each project.
The objective is not
Do more work.
The objective is
Produce more gross profit per dollar of overhead and per crew-day.
