The Arizona Inventory Index 2026
An Annual Study of Retail Inventory Habits, Accuracy, and Loss Trends.
Executive Summary: The Arizona Context
In 2025, inventory inaccuracy cost Arizona small businesses an average of 8% of total revenue.
Arizona's retail landscape faced a unique "double-threat": record-breaking Organized Retail Crime (ORC) and a growing Administrative Error Gap. While national shrink rates stabilized at 1.6%, Maricopa County retailers saw a 3.2% average loss, with small businesses (SMBs) bearing the highest proportional burden.
2025 Inventory Benchmarks
Comparison of key performance indicators (KPIs) between National averages and localized Arizona data.
| Category | National Average | Arizona (Maricopa County) |
|---|---|---|
| Total Shrinkage Rate | 1.6% | 3.2%*† |
| Internal (Employee) Theft | 29% | 42%‡ |
| Audit Accuracy (Internal) | 70% | 58%§ |
| Profit Margin Erosion (SMBs) | 5% - 8% | 22% - 35% |
| ORC Growth | +12% | +45%¶ |
- *
- In Maricopa County, total shrinkage averages 3.2%, significantly higher than the 1.6% national average.
- †
- The "Survival Threshold": In high-cost areas like Phoenix and Scottsdale, a sustained shrink rate above 2.5% is a leading indicator of small business closure within 18 months.
- ‡
- Arizona currently ranks 3rd in the U.S. for retail theft frequency, creating a "Theft Noise" that often masks deeper operational errors.
- §
- Small businesses using internal counts report an accuracy decay to 58% by mid-year.
- ¶
- Maricopa County's higher shrink rate is partially driven by a 45% increase in ORC case submissions to the County Attorney's Office in the last fiscal year, making precise inventory tracking a legal necessity for restitution.
Is Shrinkage Draining Your Profits?
You Might Not Be Looking in the Right Place.
While external theft (ORC) makes headlines, 2025 data shows that internal theft accounts for 42% of total inventory loss in Arizona small businesses. This is exacerbated by the 100% annual employee turnover rate currently seen in the Arizona convenience sector.
High turnover creates a "culture of transience" where staff feel less invested in the long-term health of the business. When the person counting the inventory is the same person responsible for its disappearance, the audit becomes a tool for concealment rather than correction.
Immediate Tactical Solutions for Owners
Our Expert Advice: Use these quick-win tactics to disrupt loss patterns in your business starting now:
- Clear Trash Bag Policy: Require all trash to be disposed of in clear bags to prevent "trash-theft." (hiding items to be retrieved from dumpsters later).
- Flattened Box Rule: All cardboard boxes must be flattened before leaving to ensure items aren't being "nested" inside.
- Surprise Register Audits: Mid-shift till-counts disrupt unrecorded sales.
The Takeaway: Internal theft is rarely a single large event; it is the "nickel and diming" of margins. Break this cycle by introducing an external, impartial control.
Top 10 Most Stolen Items in Arizona (2025)
Based on data from the Maricopa County Attorney's Office and the 2025 NRF PROTECT reports, these items are targeted specifically for their high resale value on platforms like Facebook Marketplace and OfferUp.
- Meat & High-End Proteins: Steaks and brisket are the #1 target in grocery/c-stores (85% of stores report this as the top category).
- Alcohol & Spirits: Premium tequila and bourbon remain high-risk due to ease of concealment and high resale value.
- Power Tools: Specifically DeWalt and Milwaukee brands (Maricopa County reported a surge in tools sold on social media marketplaces in 2025).
- Over-the-Counter (OTC) Meds: Pain relievers and allergy medications.
- Laundry Detergent Pods: A "liquid gold" commodity used as a form of currency in secondary markets.
- Cosmetics & Fragrances: High-end brands like Sephora/Ulta items; theft in this category increased by 18% in the Phoenix metro area.
- Infant Formula: Remains a top-tier target due to constant demand and high price points.
- Razors & Shaving Cartridges: Small, high-value, and easily pocketed.
- Energy Drinks: High-frequency "grab-and-go" theft, often untracked until cycle counts.
- Copper & Construction Materials: With rising metal prices in 2025, hardware stores are seeing increased "yard theft" of wiring and plumbing.
Shrinkage is rarely a one-time event; it’s a slow leak. Small, frequent losses are often mislabeled as "paperwork errors" until the annual audit reveals the true damage to your bottom line.
The Strategy: We suggest moving these 10 categories to an accelerated audit schedule. You cannot manage what you do not measure with consistency.
One Day of Clarity, 364 Days of Guesswork
The Classic Wall-to-Wall Audit Might Not Be as Robust as You Think
Small business owners in Arizona traditionally rely on Wall-to-Wall (full physical) counts once per year. However, 2025 performance data suggests this method is likely no longer sufficient to protect modern retail margins. The result is a phenomenon known as "Data Decay."
Statistical analysis confirms that within 90 days of an internal manual count, 25% of digital stock levels are already incorrect. By month six, accuracy falls below 60%.
Our Suggestions for 2026
To secure 2026 profitability, we suggest transitioning from a single "snapshot" counting to these three core habits:
Professional Cycle Counting
Instead of counting everything once, rotate high-risk/high-value categories (Pharmacy, Spirits, Power Tools) every 7 to 14 days. This keeps high-margin data fresh.
Blind Auditing
Do not give auditors access to POS "expected" numbers. This eliminates "Expectation Bias" where tired staff simply check a box.
Third-Party Validation
Utilize professional inventory services to neutralize the 10-15% error rate typical of internal staff counts. External specialists provide the specialized tools and "fatigue-free" oversight required to maintain a 98%+ accuracy standard.

- What are Targeted High-Value Cycles?
This strategy utilizes the Pareto Principle (80/20 Rule). In Arizona retail, 20% of items, specifically high-resale categories like spirits, pharmacy, and power tools, account for 80% of total shrinkage risk. Frequently auditing these "Vital Few" ensures near-constant 98%+ accuracy where it matters most, without the labor costs of a total store count.
⚠️ The "Phantom Asset" Tax Trap
If you are among the 40% of Arizona SMBs that do not perform a formal annual inventory, your balance sheet is likely carrying "Phantom Assets."
The Profit Leak
You are paying insurance premiums and personal property taxes on inventory that was stolen or broken months ago.
The IRS/ADOR Risk
In an audit, the state assumes your "last known" inventory is still on hand. Without a count, you cannot prove the loss to lower your taxable income.
"If you don't count it, it didn't happen, and you're paying for it twice."
Arizona Tax Impact: Recovering Casualty Losses
In Arizona, inventory lost to theft or casualty isn't just a loss. It can be a tax recovery opportunity. However, the Arizona Department of Revenue (ADOR) requires "Proper Books and Records" to substantiate these claims.
Casualty Loss Deductions
Under Arizona law, businesses can often deduct the cost of stolen or destroyed inventory that is not compensated for by insurance. To successfully claim this, a business must provide:
- ✔ Evidence of Value: A professional baseline inventory report established at the start of the period.
- ✔ Verification of Loss: A secondary, "closing" audit showing the precise "Gap" that occurred.
Citing A.R.S. § 13-1819, the Maricopa County Attorney's Office (MCAO) prioritizes cases where businesses can provide certified audit trails.
Without a third-party report, the burden of proof for both tax write-offs and criminal restitution often falls solely on the owner, with a low success rate. Without them, the burden of proof falls solely on the owner.
| Documentation Type | ADOR Acceptance | Restitution Probability |
|---|---|---|
| Internal Spreadsheet | Low / High Scrutiny | < 15% |
| POS System Data Only | Moderate | < 30% |
| Professional Certified Audit | High / Gold Standard | > 85% |
