How Restaurants & Retailers Protect Profit (Without The Headache)
Inventory Made Easy

The $8,000 Wake-Up Call That Changed Everything
Maria thought her food truck was killing it. Lines around the block, cash register ringing all day, social media buzzing. Then she sat down with me to do her year-end books.
The shocking truth: She’d made exactly $2,800 profit. On $8,000 in sales.
The culprit? Food costs were eating 65% of her revenue instead of the 30% industry standard. She was buying ingredients without tracking usage, throwing away expired produce, and pricing menu items based on guesswork.
Six months later, after implementing the systems I’m about to share with you, Maria’s food costs dropped to 32% and she took home $5,440.
Why Inventory Feels Hard (And How to Make It Simple)
Here’s what nobody tells you: You’re trying to “match what actually happened” to your numbers, but accounting uses clear assumptions (inventory methods) to make that possible.
The goal isn’t perfect memory—it’s consistent rules so you can price right, reorder on time, and report profits correctly.
If you only remember one formula, make it this:
Beginning Inventory + Net Purchases -Ending Inventory =COGS (periodic)....
The "Big Three" Inventory Villains (And How to Defeat Them)
Villain #1 "Ghost Inventory"
What it looks like: Your system says you have 50 units, but your shelves are empty.
Why it happens:
- Staff forgets to record waste or damage
- Theft (yes, it happens more than you think)
- System glitches that don’t update properly
- Items getting moved between locations without tracking
The Fix – The Daily Reality Check
Morning inventory +Deliveries – Sales – Waste = Evening inventory
If this doesn’t match your actual count, you have a leak.
Use the tracking methods in our sheet to catch these discrepancies before they become disasters.
Villain #2: "Spoilage Surprise"
What it looks like: You think you're profitable until you realize $2,000 worth of food expired this month..
The Restaurant Reality: Fresh ingredients don’t wait for your convenience. Lettuce doesn’t care about your profit margins.
The Numbers: Restaurants typically waste 4-10% of food purchased. Most owners don’t track it, so they don’t know their real food costs.
The Fix – The FIFO Foundation:
FIFO = First In, First Out (Use old stuff first)
Implementation:
- Date everything when it arrives
- Organize coolers/freezers with oldest in front
- Train staff to grab from front first
- Daily “use today” shelf for items near expiration
- Track waste with reasons (overordering vs. spoilage vs. prep mistakes)
The Advanced Move: Create “Manager’s Special” pricing for items within 24 hours of expiration. Better to sell at cost than throw away at total loss.
Secret: The best restaurants track waste by category and staff member. Patterns reveal training opportunities and ordering adjustments.
Villain #3:"Price Whiplash"
What it looks like: Your wholesale costs jump 30% due to tariffs, supply chain issues, or inflation, but your retail prices are locked in with printed tags.
The Retailer Reality:
- Tariffs change overnight
- Fuel costs affect shipping
- Currency fluctuations impact imports
- Supplier consolidations drive prices up
The Result: You’re selling products at a loss without knowing it.
The Fix – The Price Alert System:
Track Your “Big 20”: The 20% of products that drive 80% of your revenue.
Set Up Triggers:
- 15% wholesale increase = immediate price review
- 25% increase = emergency repricing
- Monitor competitor pricing weekly
The Buffer Strategy:
- Build 10-15% margin buffer into initial pricing
- Use price tags that can be easily updated
- Consider dynamic pricing for online sales
The Dirty Truth About Inventory Accounting (That No One Talks About)
Secret #1: Your Inventory Method is a Tax Strategy, Not Just Bookkeeping
Here’s what I tell my clients:
LIFO in Inflationary Times = Instant Tax Savings
- When prices rise, LIFO gives you higher COGS (using recent expensive inventory first)
- Higher COGS = lower taxable income = thousands saved
- But: Once you elect LIFO, you’re married to it. The IRS requires LIFO for ALL financial reporting
The LIFO Reserve Trap: If you ever switch away from LIFO, you’ll owe taxes on the entire “LIFO reserve” accumulated over years. I’ve seen businesses owe $500K+ in catch-up taxes.

FIFO During Deflation = Hidden Opportunity
- When prices fall, FIFO becomes your tax friend
- Using older (expensive) inventory first = higher COGS = lower taxes
- Perfect for tech companies where component costs drop yearly

The Accountant’s Trick: Time your physical counts strategically. Count right after holiday sales when inventory is naturally low, not right after big deliveries.
Advanced Move: Establish shrinkage reserves. Instead of massive year-end adjustments, estimate monthly shrinkage and adjust gradually. Smoother cash flow, fewer red flags
Secret #2: The "Shrinkage" Game
Everyone talks about tracking shrinkage. Nobody explains how to use it strategically.
Normal vs. Abnormal Shrinkage:
- Normal shrinkage (0.5-2%): Goes to COGS, reduces taxable income
- Abnormal shrinkage (theft, flood, fire): Separate deduction as casualty loss

The “Profit Protection” Formula That Actually Works
Most inventory systems focus on counting stuff. This formula focuses on protecting money.
- It’s Built for Real Business Owners: Designed by someone who’s actually run businesses, not just studied them in textbooks. Every step solves a real problem I’ve seen destroy profits.
- Small Actions, Big Results: 15 minutes daily with small consistent efforts.
- Catches Problems Early: Most inventory issues start small and grow into disasters.
- Works Without Perfect People: Your staff doesn’t need accounting degrees. The system is designed for busy people who make mistakes and forget things.
Transform your inventory chaos into predictable profit in just 4 steps
Your Financial Superhero Transformation Starts Now
The real cost of not tracking inventory isn’t just money—it’s your sanity, your sleep, and your dreams. Every day you operate without proper inventory control is another day you’re working for everyone else except yourself. Your suppliers get paid, your landlord gets paid, your employees get paid, but you? You’re left wondering where all the money went.
