The Profit Leak Audit
Seven numbers you already know. It ranks where your profit is actually leaking, biggest first, then sends you straight to the calculator that fixes each one. This is the engine that ties the videos, the calculators, and the book together.
Pricing
Margin, markup, discounts, and the price you should never go below.
The Discount Breakdown
You cut your price. How much more do you have to sell just to make the same gross profit?
A same size price increase at this margin lets you lose up to of your volume and still make the same gross profit. The cut and the raise are not symmetric.
Before you approve a discount, run it here. If the volume it needs is unrealistic, hold your price or trade the discount for something that does not cost margin.
The Markup vs Margin Trap
A markup is not a margin, and the gap is bigger than it feels.
Price to the margin you want, not the markup that feels right. Set your target margin first, then back into the markup.
The Floor Price
The price below which you are paying for the privilege of working.
Put your floor price on a card by the phone. No quote goes out below it without a reason you can say out loud.
Discount Recovery
You gave the discount. Now how much must you raise prices later just to get back to where you started?
Remember the asymmetry before you discount. A cut is easy to give and surprisingly hard to claw back.
Customers
Who makes you money, what they really cost, and the risk of leaning on one.
Customer Concentration Risk
One big customer feels like security. See how much of the business walks out the door if they leave.
Concentration over 25% is a risk a buyer or lender will price against. Diversify the book before you are forced to.
The Customer P&L
Revenue is not profit. Add up what it really costs to keep an account and some turn red.
Run your top five accounts through this, then use the Customer Scorecard to break the costs out line by line.
Customer Scorecard
Margin is only the start. Add terms, service, rush orders, returns, and discounts, and the verdict gets honest.
Score every account green, yellow, or red. Reprice or fire the red ones before you spend a dollar chasing new logos.
CAC to LTV
Are you buying customers profitably, and how long until they pay you back?
If the ratio is under three to one, fix retention or acquisition cost before you spend another dollar scaling.
The Free Shipping Cost
Free shipping is not free. See what eating it does to the margin on every order.
Set a free-shipping threshold at or above the break-even order value so the offer pays for itself.
Cash
Where your money gets trapped and what growth quietly demands.
The Cash Conversion Cycle
How many days does your money sit trapped between paying for goods and getting paid for them?
Pick the single biggest number of the three and attack it: invoice faster, hold less stock, or negotiate longer terms.
Working Capital Requirement
A full order book can mean you are going broke. See the cash you must front to fund growth before it pays you back.
Line up the cash before you take the orders. Growth you cannot fund is how a profitable company runs out of money.
Growth Will Bankrupt You
Profit on paper, empty in the bank. See whether your growth funds itself or eats your cash.
If growth is burning cash, slow the ramp or fix the cash gap first. Profitable and broke is still broke.
The Cost of Being the Bank
When you give net terms, you finance your customers for free. Here is the bill.
Every day you shave off your terms is cash back in your account. Tighten the slowest payers first.
Cost
What things really cost, and how hard you can run before it breaks.
The True Cost of an Employee
The wage is the smallest part. Here is what a person costs for every productive hour.
Use the loaded hourly cost when you quote and when you decide what work is worth your team’s time.
Break-even and Operating Leverage
How many units you must sell to cover the lights, and why a small swing in sales swings profit far more.
Know your break-even before the month starts. Everything above it is where your profit actually lives.
The Cost of Rework
Every job done twice is pure margin walking out the door. Add it up for the year.
Treat the rework number as a budget you are trying to zero out. A point of quality is often worth more than a point of sales.
Utilization
Busier is not always better. Past a point, high utilization means fragility, late jobs, and no room for the profitable rush.
Aim for the 70 to 85% band. Below it you waste capacity, above it you cannot absorb surprises or say yes to the good rush job.
Growth
The decisions where bigger is not automatically better.
Revenue vs Profit Illusion
Two options. One has the bigger top line. Which one actually makes more money?
Judge every deal and product line by the profit it makes, not the revenue it adds.
Take the Job or Walk
A specific bid is on the table. Decide on the spot whether it is worth your time.
Set your minimum dollars per hour once. Then this is a yes or no, not a gut call.
Buy vs Rent Equipment
Own it or rent it? Compare the real cost over how long and how often you will actually use it.
If you will use it less than the break-even months a year, rent. Own only what you keep busy.
Industry packs
Tools tuned to how your business actually makes money.
The traps under a construction bid, a retail markdown, and an online order are not the same. Each pack speaks your numbers.
Construction
Bids, labor, retainage, and whether the job will actually make money.
Bid Markup for Overhead and Profit
Marking up cost by your profit target quietly leaves out overhead. Here is the markup that recovers both.
Stop marking up by gut. Recover overhead and profit in every bid, or you grow revenue while the bank account shrinks.
True Cost of a Crew Hour
The wage is the start. Add burden, small tools, and the hours that are not on the work, and the real number jumps.
Build your labor rate off the billable-hour cost, not the wage. Travel, setup, and weather are not free.
Retainage Cash Impact
Owners hold back a slice of every contract. See how much of your money is parked in their account.
Price retainage into the job and chase releases the day they are due. It is your money, financed for free.
Job Profit Forecast
Do not wait for closeout to learn the job lost money. Forecast the final margin from where it stands today.
Run this on every active job monthly. A fade you catch at 40% complete is fixable. The same fade at closeout is just a loss.
Change Order Recovery
You did the extra work. Now you wait to get paid. See what slow change orders cost while the money sits out there.
Get change orders approved and billed before the work starts wherever you can. A disputed one risks the whole margin, not just the float.
Manufacturing
Hidden capacity, the real constraint, and the cost of sitting on stock.
OEE Impact
Overall equipment effectiveness multiplies three losses you usually track separately. The hidden capacity is bigger than it looks.
Chase the lowest of the three factors first. A small dip in each one compounds into a large lost number at the end of the line.
Bottleneck Finder
Your line is only as fast as its slowest step. Find the real constraint before you spend on the wrong one.
Invest at the bottleneck and nowhere else until it moves. Capacity added upstream just piles up inventory in front of the constraint.
Inventory Carrying Cost
The purchase price is not the cost. Capital, storage, insurance, and obsolescence make inventory far more expensive to hold than to buy.
Carrying cost usually runs 20 to 30% a year. Hold that against every reorder and every quantity break before you stock up.
Retail
Inventory, markdowns, and what your floor space earns.
GMROI
Margin and turns together decide whether your inventory earns its keep. Gross margin return on inventory shows it in one number.
A fat margin on slow stock can lose to a thin margin that turns fast. Manage to GMROI, not margin alone.
Markdown Breakeven
A markdown looks small on the tag and large on the profit. See how much margin a price cut actually keeps.
Mark down dead stock fast and protect fresh inventory. Every point off the price takes more than a point off the profit.
Occupancy Cost
Rent is fixed whether the store is packed or empty. See what your space costs as a share of what it sells.
If occupancy eats too much of your gross margin, you need more sales per foot or a smaller footprint.
Online business
Ad payback, unit economics, and the churn that caps growth.
Break-even ROAS
Before you judge an ad campaign, know the return on ad spend you need just to avoid losing money.
Set your target ROAS above break-even by your profit goal. Anything under break-even scales losses, not sales.
Contribution per Order
Add up product, shipping, fees, and ads. What an order actually leaves behind is smaller than the price suggests.
Fix unit economics before you scale traffic. Pouring ad spend onto a negative contribution just loses money faster.
Subscription Churn and LTV
Churn is a leaky bucket. See what a subscriber is really worth and how fast the leak drains your base.
A point of churn cut compounds into months of extra lifetime. Retention is the cheapest growth you have.
Hospitality
Rooms, rates, and the occupancy that actually pays.
RevPAR and Profit per Available Room
The hotel north-star. What every room earns per night, full or empty, before and after the cost of the rooms that sell.
Manage RevPAR, not rate or occupancy alone. The goal is the most profitable mix, not the fullest hotel.
Break-even Occupancy
How full you have to be just to cover the fixed costs at your current rate.
Know your break-even occupancy before you discount. Below it, you are paying guests to stay.
Rate vs Occupancy
Tempted to cut the rate to fill rooms? See how much occupancy you would need just to make it back.
A rate cut almost always needs more occupancy than you expect. Defend rate before chasing heads in beds.
Restaurants
Plate costs, prime cost, and the covers that break you even.
Plate Cost and Menu Price
Work backward from your food-cost target to the price a dish has to carry on the menu.
Cost every dish and price to your food-cost target. Menus drift, so recost the big sellers every quarter.
Prime Cost
Food plus labor as a share of sales. The single number that predicts whether a restaurant makes it.
Watch prime cost weekly, not monthly. It moves fast and it is the first thing to drift when a kitchen gets busy.
Break-even Covers
How many guests you have to serve a day before the restaurant makes its first dollar.
Know your nightly break-even cover count. Everyone you seat past it is where the profit lives.
Property rentals
Cash flow, cap rate, and the quiet cost of empty units.
Rental Cash Flow
After vacancy, expenses, and the mortgage, does this unit feed you or feed on you?
Buy for cash flow, not just appreciation. A unit that bleeds every month is a liability with a nice story.
Cap Rate
What the building earns relative to what it costs, before any financing. The number that compares deals.
Compare deals on cap rate, then stress test the expenses. Sellers almost always understate operating costs.
Cost of Vacancy
Empty days plus make-ready costs add up faster than most owners think. Here is the annual bill.
A few weeks empty plus a turnover often costs more than a rent bump earns. Renew good tenants early.
Property maintenance
Pricing calls and contracts, and when to schedule instead of scramble.
Service Call Pricing
What to charge for a call so loaded labor hits your margin and parts carry a real markup.
Price every call off your loaded tech cost and a real parts markup. Drive time and overhead are not free.
Maintenance Contract Pricing
Price a recurring agreement so it holds your margin across every scheduled visit and every part.
Price recurring agreements to your margin, not the customer budget. Predictable revenue is worth holding the line.
Reactive vs Preventive
Running to failure feels cheap until you add up the emergency calls. Compare it to a maintenance schedule.
Schedule the critical, high-failure assets and let cheap, redundant ones run to failure. Match the plan to the risk.
Marketing
Spend, funnels, and the conversion that has to pay it back.
Marketing ROI
Revenue is not the score. After cost of goods and the spend itself, did the campaign actually make money?
Judge campaigns on profit after margin and spend, not on revenue or clicks. A busy campaign can still lose money.
Cost per Customer
A cheap lead is not a cheap customer. Run the funnel and the real cost to acquire a buyer jumps.
Budget to cost per customer, not cost per lead. The conversion step is where most of the real cost hides.
Break-even Conversion
Before you launch, know the conversion rate the campaign has to hit just to pay for itself.
Set the break-even conversion as your floor. If your historical rate is below it, fix the offer before you spend.
Sales
Pipeline coverage, the cost of a rep, and margin after the deal.
Pipeline Coverage
Hitting a number is a math problem. See how much qualified pipeline you need behind your target.
Build pipeline to the coverage ratio, not to the target. Carrying only one times your number all but guarantees a miss.
Cost of a Sales Rep
A rep is a big fixed bet. See the revenue they must generate before they pay for themselves, let alone turn a profit.
Quota a rep off the revenue that returns a healthy multiple of their cost, not off a round number that feels fair.
Margin After Discount and Commission
The rep discounts to win it, then takes a commission on it. See what margin is left when both land.
Give reps a discount floor that protects margin after commission. A deal can look like a win and still lose money.
Public relations
Earned value, share of voice, and the cost of a placement.
Earned Media Value
Put a number on coverage by asking what the same reach would cost to buy as advertising. Directional, not exact.
Use earned value to show scale, but pair it with real outcomes. It estimates reach, not trust or intent.
Share of Voice
How much of the category conversation is about you, and is it running ahead of your market share or behind it?
Aim to hold more share of voice than market share. That gap, when positive, is what tends to pull share your way.
Cost per Placement
Pitching is a numbers game with a hit rate. See what each earned story actually costs you to land.
Track cost per placement over time. Rising cost means the pitch or the target list needs work, not more volume.
