# What Is Costing in Cost Accounting? Published: 2025-11-16 Author: Warren Team URL: https://www.heywarren.com/blog/costing-cost-accounting --- Most manufacturing companies spend between 60% and 80% of their revenue on production costs — yet studies show fewer than 30% of small and mid-sized businesses track those costs in any systematic way. That gap is not a small problem. Without a clear picture of what things actually cost to make or deliver, business owners set prices by gut feel, miss profit leaks hiding in overhead, and make capital decisions based on accounting fiction. Costing [cost accounting](/blog/cost-accounting) exists precisely to close that gap — and most people either confuse it with financial accounting or ignore it entirely. By the end of this guide, you will understand what costing in cost accounting means, which costing method fits your business, and how to use cost data to make smarter pricing, budgeting, and investment decisions. You will also see where companies go wrong — so you can avoid those traps before they cost you real money. According to a 2023 survey by the Institute of Management Accountants, businesses that implement formal cost accounting practices improve their gross margins by an average of 8 percentage points within two years. That kind of improvement does not come from selling more. It comes from understanding exactly what you are spending. --- ## What Is Costing in Cost Accounting? Costing in cost accounting is the process of systematically identifying, measuring, and assigning the costs required to produce a product or deliver a service. It provides managers with the unit-level cost data they need to set prices, control spending, and evaluate operational efficiency. Unlike financial accounting, which reports historical results to outsiders, cost accounting is an internal tool built for decision-making. ![Every cost accounting system classifies production costs into direct materials, direct labor, and manufacturing overhead.](data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20600%20211%22%20width%3D%22600%22%20height%3D%22211%22%20role%3D%22img%22%3E%3Ctitle%3EHierarchy%3C%2Ftitle%3E%3Crect%20width%3D%22100%25%22%20height%3D%22100%25%22%20fill%3D%22%23f8fafc%22%2F%3E%3Crect%20x%3D%22220%22%20y%3D%2220%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22%232563eb%22%2F%3E%3Ctext%20x%3D%22300%22%20y%3D%2254%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22700%22%20fill%3D%22white%22%3ETotal%20Product%20Cost%3C%2Ftext%3E%3Cpath%20d%3D%22M%20300%2078%20L%20300%20105.5%20L%20120%20105.5%20L%20120%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%2240%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22120%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EDirect%20Materials%3C%2Ftext%3E%3Ctext%20x%3D%22120%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3ERaw%20inputs%20in%20product%3C%2Ftext%3E%3Cpath%20d%3D%22M%20300%2078%20L%20300%20105.5%20L%20300%20105.5%20L%20300%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%22220%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22300%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EDirect%20Labor%3C%2Ftext%3E%3Ctext%20x%3D%22300%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EWages%20on%20product%3C%2Ftext%3E%3Cpath%20d%3D%22M%20300%2078%20L%20300%20105.5%20L%20480%20105.5%20L%20480%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%22400%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22480%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EMfg%20Overhead%3C%2Ftext%3E%3Ctext%20x%3D%22480%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3ERent%2C%20utilities%2C%20deprecia%E2%80%A6%3C%2Ftext%3E%3C%2Fsvg%3E) *Every cost accounting system classifies production costs into direct materials, direct labor, and manufacturing overhead.* Think of cost accounting as the financial X-ray of your operations. Where a standard income statement tells you that your company spent $2 million on production last quarter, a proper costing system tells you exactly how much it cost to produce each individual unit — broken down by materials, labor, and the overhead you burned along the way. The practice traces back to the Industrial Revolution, when factories needed a way to determine whether a single product line was profitable after allocating shared machinery costs. Today, it is just as relevant for software companies allocating cloud infrastructure costs as it is for a factory floor. Every costing cost accounting system tracks three fundamental cost categories: - **Direct materials**: raw materials or components that physically become part of the final product - **Direct labor**: wages paid to workers who directly touch the product - **Manufacturing overhead**: indirect costs like rent, utilities, equipment depreciation, and factory supervision Understanding these categories is step one. Step two is choosing the right method to assign them. --- ## The Five Main Costing Methods Not every business should use the same cost accounting method. The right choice depends on your industry, production volume, and the granularity of data you actually need to make decisions. ![The five main costing methods each suit different industries and production types.](data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20760%20211%22%20width%3D%22760%22%20height%3D%22211%22%20role%3D%22img%22%3E%3Ctitle%3EHierarchy%3C%2Ftitle%3E%3Crect%20width%3D%22100%25%22%20height%3D%22100%25%22%20fill%3D%22%23f8fafc%22%2F%3E%3Crect%20x%3D%22300%22%20y%3D%2220%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22%232563eb%22%2F%3E%3Ctext%20x%3D%22380%22%20y%3D%2254%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22700%22%20fill%3D%22white%22%3ECosting%20Methods%3C%2Ftext%3E%3Cpath%20d%3D%22M%20380%2078%20L%20380%20105.5%20L%20110%20105.5%20L%20110%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%2230%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22110%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EStandard%3C%2Ftext%3E%3Ctext%20x%3D%22110%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EPredetermined%20unit%20cost%3C%2Ftext%3E%3Cpath%20d%3D%22M%20380%2078%20L%20380%20105.5%20L%20290%20105.5%20L%20290%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%22210%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22290%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EActivity-Based%3C%2Ftext%3E%3Ctext%20x%3D%22290%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3ECost%20by%20activity%20driver%3C%2Ftext%3E%3Cpath%20d%3D%22M%20380%2078%20L%20380%20105.5%20L%20470%20105.5%20L%20470%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%22390%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22470%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EJob-Order%3C%2Ftext%3E%3Ctext%20x%3D%22470%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EPer%20job%20or%20batch%3C%2Ftext%3E%3Cpath%20d%3D%22M%20380%2078%20L%20380%20105.5%20L%20650%20105.5%20L%20650%20133%22%20stroke%3D%22%23cbd5e1%22%20stroke-width%3D%222%22%20fill%3D%22none%22%2F%3E%3Crect%20x%3D%22570%22%20y%3D%22133%22%20width%3D%22160%22%20height%3D%2258%22%20rx%3D%228%22%20fill%3D%22white%22%20stroke%3D%22%230891b2%22%20stroke-width%3D%222%22%2F%3E%3Ctext%20x%3D%22650%22%20y%3D%22158%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2213%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EProcess%3C%2Ftext%3E%3Ctext%20x%3D%22650%22%20y%3D%22176%22%20text-anchor%3D%22middle%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2210%22%20fill%3D%22%2364748b%22%3EContinuous%20production%3C%2Ftext%3E%3C%2Fsvg%3E) *The five main costing methods each suit different industries and production types.* ### Standard Costing Standard costing assigns a predetermined (standard) cost to each unit of output, based on expected material quantities, labor hours, and overhead rates. At the end of a period, accountants compare actual costs against the standard and report the difference as a **variance**. A variance can be favorable — you spent less than expected — or unfavorable, meaning costs ran over. The real power is in investigating why the variance exists. A 12% unfavorable labor variance might reveal an undertrained workforce, a broken machine slowing the line, or a supplier delivering low-quality materials that require rework. Standard costing works best for: - High-volume, repetitive manufacturing - Businesses with stable input costs - Companies where variance analysis drives continuous improvement Its weakness is that standards can become outdated. If you set your standard cost based on 2022 raw material prices and inflation has pushed those prices up 30%, every period will show an unfavorable variance that obscures real performance. ### Activity-Based Costing [Activity-based costing (ABC)](/blog/abc-costs) assigns overhead costs to products based on the specific activities that generate those costs, rather than spreading overhead uniformly across all units. A product that requires 40 quality inspections should absorb more quality-control cost than one that requires two. ABC was developed in the late 1980s by Robin Cooper and Robert Kaplan at Harvard Business School, in response to the limitations of traditional overhead allocation. It is more expensive to implement — you need to map all activities, assign cost drivers, and maintain more detailed records — but it delivers far more accurate product costs. Consider a company that makes two products: a basic widget and a custom widget. Traditional overhead allocation might assign the same overhead rate per machine hour to both. But the custom widget requires 10 times more engineering support, 5 times more setups, and 3 times more inspections. ABC captures that reality; traditional costing does not. ### Job-Order Costing Job-order costing (also called job costing) tracks costs for each distinct job, batch, or customer order separately. A law firm billing by client, a construction company tracking each project, or a print shop pricing custom orders all use some form of job costing. Each job gets its own **cost sheet**, accumulating direct materials, direct labor, and an allocated share of overhead as the work progresses. When the job is finished, the total on the cost sheet becomes the cost of goods sold for that specific order. This method provides excellent traceability but generates significant administrative work at scale. ### Process Costing Where job costing tracks individual orders, process costing tracks costs across a continuous production process. Oil refineries, paint manufacturers, and food processors use process costing because their output is homogeneous — one gallon of paint is identical to the next. Costs accumulate by department or process stage, and accountants compute an **equivalent unit** calculation to deal with partially complete inventory at period end. ### Marginal Costing Marginal costing (also called variable costing or direct costing) assigns only variable costs to products — direct materials, direct labor, and variable overhead. Fixed overhead costs go directly to the income statement as period costs, not into inventory. This method is not accepted under [GAAP](https://www.fasb.org/) for external reporting, but it is extremely useful for internal decisions like whether to accept a special order at a lower-than-normal price. --- ## How Cost Accounting Differs from Financial Accounting [Cost accounting and](/blog/cost-accounting-and) financial accounting draw from the same raw data, but they serve completely different audiences and answer completely different questions. **Financial accounting** follows GAAP or [IFRS](https://www.ifrs.org/) rules, produces quarterly and annual statements, and reports to investors, creditors, and regulators. It looks backward. Its primary outputs — the income statement, balance sheet, and cash flow statement — are mandatory for public companies and standardized so external users can compare firms. **Cost accounting** is voluntary, internally focused, and forward-looking. A company can design its cost accounting system however best serves management. There are no auditors checking that your overhead allocation method is "correct." The practical difference shows up in how each treats **fixed overhead**. Under financial accounting (absorption costing), fixed manufacturing overhead goes into inventory on the balance sheet and flows to the income statement only when the goods sell. Under variable costing, that same overhead hits the income statement immediately. This distinction can create dramatically different profit figures in the same period — a fact that trips up many executives who do not understand why their management reports and their audited statements tell different stories. A third category, **management accounting**, is sometimes used as a synonym for cost accounting. The distinction is slight: management accounting is the broader discipline (covering budgeting, performance measurement, and strategic analysis), while cost accounting is its foundational tool for measuring what things cost to produce. --- ## Why Costing Data Drives Better Business Decisions Accurate cost data is not just an accounting exercise — it is the foundation for almost every significant operational and strategic decision a business makes. ### Pricing Strategy You cannot price profitably without knowing your true unit cost. Businesses that price based on competitor benchmarks or intuition often discover — too late — that they have been selling certain products below their fully loaded cost. A restaurant that uses recipe costing (a form of job costing) knows that a particular pasta dish costs $4.80 in food cost alone. Factor in labor, utilities, and rent allocation, and the true cost might be $9.50. Pricing it at $12 generates a 21% margin. Without that calculation, a manager might cut the price to $10.50 to stay competitive, not realizing they are eroding profit by nearly 50%. A disciplined costing cost accounting approach forces this math before the menu goes to print. ### Budget Planning and Variance Analysis Standard costing feeds directly into the annual budget process. When you know your standard material cost per unit, your budgeted labor hours per run, and your planned overhead rate, you can build a credible production budget from the bottom up. During the year, monthly variance reports flag where reality is drifting from plan. A $45,000 unfavorable material price variance in February is a signal — investigate now, not at year end. Maybe a supplier raised prices without notice. Maybe procurement is buying from a more expensive backup supplier because the primary one is backordered. Variance analysis transforms cost accounting from a scorekeeping function into a real-time management tool. --- ## Real-World Examples of Cost Accounting in Action Seeing how companies actually apply costing concepts makes the theory concrete. ![A bakery pricing wholesale bread at $2.25 earns a 15.6% margin — but cutting to $2.10 without knowing the $1.90 unit cost nearly wipes it out.](data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20800%20210%22%20width%3D%22800%22%20height%3D%22210%22%20role%3D%22img%22%3E%3Ctitle%3EComparison%3C%2Ftitle%3E%3Crect%20width%3D%22100%25%22%20height%3D%22100%25%22%20fill%3D%22%23f8fafc%22%2F%3E%3Ctext%20x%3D%22230%22%20y%3D%2257.5%22%20text-anchor%3D%22end%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EPriced%20at%20%242.25%3C%2Ftext%3E%3Crect%20x%3D%22240%22%20y%3D%2225%22%20width%3D%22450%22%20height%3D%2255%22%20rx%3D%226%22%20fill%3D%22%232563eb%22%2F%3E%3Ctext%20x%3D%22702%22%20y%3D%2257.5%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22700%22%20fill%3D%22%232563eb%22%3E%2516%3C%2Ftext%3E%3Ctext%20x%3D%22230%22%20y%3D%22152.5%22%20text-anchor%3D%22end%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22600%22%20fill%3D%22%230f172a%22%3EPriced%20at%20%242.10%3C%2Ftext%3E%3Crect%20x%3D%22240%22%20y%3D%22120%22%20width%3D%22274.03846153846155%22%20height%3D%2255%22%20rx%3D%226%22%20fill%3D%22%237c3aed%22%2F%3E%3Ctext%20x%3D%22526.0384615384615%22%20y%3D%22152.5%22%20font-family%3D%22system-ui%2C-apple-system%2Csans-serif%22%20font-size%3D%2214%22%20font-weight%3D%22700%22%20fill%3D%22%237c3aed%22%3E%259.5%3C%2Ftext%3E%3C%2Fsvg%3E) *A bakery pricing wholesale bread at $2.25 earns a 15.6% margin — but cutting to $2.10 without knowing the $1.90 unit cost nearly wipes it out.* **Toyota and Standard Costing**: Toyota's production system (TPS) is famous for lean manufacturing, but it is equally famous for rigorous standard costing and variance tracking. Every production cell has a target cost per unit. Deviations trigger root-cause analysis (the "5 Whys" process) immediately, not at month-end close. This tight feedback loop is one reason Toyota maintains gross margins above 18% in a notoriously competitive industry. **Amazon Web Services and Activity-Based Costing**: AWS prices cloud services by granular cost drivers — compute hours, data transfer gigabytes, API calls, storage reads and writes. Internally, AWS almost certainly uses an ABC-style approach to allocate data center costs across thousands of distinct service offerings, ensuring each product is priced to cover its true resource consumption. **A Small Bakery Example**: A bakery owner wants to know whether her wholesale bread line is profitable. Her direct material cost per loaf is $0.85 (flour, yeast, packaging). Direct labor is $0.60 per loaf based on bakers' hourly wages and production rates. She allocates $0.45 of overhead per loaf based on oven hours. Total unit cost: $1.90. She sells wholesale at $2.25, generating a 15.6% gross margin. Without this calculation, she had no idea whether to expand the line or drop it. These examples span industries and scales, but the underlying costing cost accounting logic is identical. --- ## Common Mistakes in Cost Accounting (and How to Avoid Them) Even companies that have a cost accounting system in place often undermine it with avoidable errors. **Misclassifying costs as direct or indirect.** Some businesses treat supervisory wages as direct labor because supervisors are physically present on the production floor. But if those supervisors manage multiple product lines, their wages are indirect — they belong in overhead and should be allocated, not assigned to a single product. Misclassification distorts unit costs and leads to bad pricing decisions. **Using a single overhead allocation rate for everything.** Applying one plant-wide overhead rate — say, $18 per machine hour — across all products makes the math simple but the answers wrong. A product that uses the engineering department heavily but few machine hours looks artificially cheap. Separate overhead pools by cost center or activity, even if you do not implement a full ABC system. **Ignoring idle capacity costs.** When production volumes fall, fixed overhead spreads across fewer units, raising per-unit cost. Some managers respond by cutting prices to boost volume — which makes the problem worse. Understanding that idle capacity cost is a period issue, not a product costing issue, prevents this mistake. **Failing to update standards.** Standard costs set at the beginning of the year become meaningless if material prices or wage rates change significantly mid-year. Build a quarterly standards review into your process. **Confusing cost accounting with cost reduction.** Cost accounting shows you where money goes. It does not automatically tell you where to cut. A 40% overhead allocation to a product might be entirely appropriate — or it might signal waste. The data opens the conversation; management judgment closes it. --- ## Related Reading **More from Warren**: - [Revenue Recognition Explained: ASC 606 & IFRS 15 Guide](/blog/revenue-recognition) - [Swiss Bank Account: What It Is, How to Open One, and What to Know](/blog/account-swiss-bank) - [Balancing Ledgers: A Step-by-Step Guide for Modern Bookkeepers](/blog/balancing-ledgers) ## Authoritative Sources For deeper background and primary-source data on this topic, the following authoritative sources are useful starting points: - [AICPA](https://www.aicpa-cima.com/) - [Public Company Accounting Oversight Board](https://pcaobus.org/) - [Securities and Exchange Commission](https://www.sec.gov/) - [Government Accountability Office](https://www.gao.gov/) ## Conclusion Cost accounting is one of the most practical tools in any business owner's or financial manager's arsenal. Here are the key takeaways from this guide: - **Costing cost accounting** assigns direct materials, direct labor, and overhead to products or services so you know the true unit cost of everything you make or deliver. - **Five main methods** — standard, activity-based, job-order, process, and marginal costing — serve different industries and decision needs. Choosing the right one matters. - **Cost accounting is not financial accounting.** It is internal, flexible, and built for decisions — not external reporting. - **Accurate cost data drives pricing, budgeting, and variance analysis.** Without it, you are guessing. - **Common mistakes** — misclassifying costs, using a single overhead rate, and neglecting to update standards — erode the accuracy of any costing system. The businesses that outperform their peers over time are rarely the ones that sell the most. They are the ones that understand their numbers at the unit level and act on what those numbers reveal.
