Operating expenses are often treated as the leftover section of the profit and loss statement. In reality, they reveal how an organization plans, maintains what it depends on, responds to pressure, and turns responsibility into routine.
A repair invoice arrives after a cooler fails. A software subscription renews even though few people use it. Smallwares rise for the third month in a row. Professional fees increase because the accounting team is cleaning up work that should have been completed earlier. None of these items appears connected when reviewed one account at a time.
Taken together, however, they tell a story about the organization: whether it plans or reacts, whether ownership is clear, whether systems are maintained, whether purchasing is disciplined, and whether small decisions are allowed to become recurring commitments.
Operating expenses are not merely amounts to reduce. They are evidence of organizational habits.
The bottom half of the P&L is not a junk drawer
Revenue, cost of goods sold, and labor describe much of the economic engine of a restaurant. Operating expenses show what supports that engine: facilities, tools, vendors, systems, maintenance, insurance, marketing, professional support, and daily supplies that allow the business to keep operating.
Because the accounts are diverse, leaders sometimes treat them as a miscellaneous list beneath prime cost. That is a mistake. This section can reveal how purchases are approved, whether maintenance is preventive or reactive, whether vendors and subscriptions are actively managed, whether responsibility is clear, and whether the organization invests before a need becomes a crisis.
These are habits, not moral verdicts. A high expense does not automatically mean carelessness, and a low expense does not automatically mean discipline. The purpose is to understand what produced the result, not to attach blame to it.
An expense account is an outcome, not an explanation
OPERATING EXPENSE = PRICE OR RATE × ACTIVITY OR USAGE + FIXED COMMITMENTS + TIMING AND EXCEPTIONS
A utility increase may come from higher rates, greater consumption, longer operating hours, failing equipment, unusual weather, or a billing adjustment. Supplies may rise because of more transactions, channel mix, unit prices, poor par levels, breakage, or inconsistent purchasing. Professional fees may reflect deliberate investment—or expensive cleanup created by weak internal processes.
The response should depend on the cause. Cutting an expense before understanding its drivers can remove something the business needs while leaving the habit that created the problem untouched.
Classify the expense before deciding what it means
Structural commitments
Rent, insurance, licenses, and many technology contracts are established by earlier decisions. They may not change with this month’s sales, but they still deserve review when a lease is signed, a policy renews, a location is evaluated, or a contract reaches its notice date.
Activity-driven costs
Credit-card fees, disposables, linen, laundry, some utilities, and certain delivery or transaction costs respond to operating volume or channel mix. These are often clearer when reviewed per transaction, cover, order, labor hour, or another unit of activity.
Stewardship and maintenance costs
Repairs, preventive maintenance, cleaning, training, safety, and replacement supplies protect the assets and people that make service possible. A low number can signal efficiency, but it can also signal deferred care that surfaces later as downtime, burnout, risk, or a larger capital need.
Event-driven and timing-sensitive costs
Annual renewals, one-time projects, emergency repairs, legal matters, and accounting adjustments can distort one month. Accurate accruals, consistent coding, and separation between recurring operations and unusual events matter before interpreting the trend.
Discretionary investments
Marketing initiatives, advisory work, technology implementations, training, and process improvements may be intentionally chosen. Evaluate them against the purpose they were meant to serve, the capability they were meant to build, and the assumptions that supported the decision.
Different categories reveal different habits
A single operating-expense percentage cannot manage every account. Higher sales can make weak expense practices look healthier; lower sales can make a stable commitment appear suddenly wasteful. The better question is not simply, “Is this expense over budget?” It is, “What pattern of decisions and activity created it?”
- Repairs & maintenance: preventive vs. emergency work, repeat failures, downtime, asset age, repair-or-replace decision.
- Supplies & smallwares: spend per cover/order, unit price, pars, ordering frequency, breakage, loss, channel mix.
- Utilities & occupancy: rate vs. consumption, operating hours, equipment efficiency, space utilization, fixed commitments.
- Technology: cost per location/user, active use, duplicate tools, contract terms, renewal ownership.
- Marketing: objective, campaign/location, audience, response or conversion where measurable, and learning generated.
- Professional fees: recurring support vs. project or cleanup, scope, internal process gap, capability created, preventable rework.
Variance review should create understanding, not fear
- Confirm the information. Check coding, cutoff, accruals, allocation, and comparability.
- Separate the drivers. Distinguish price or rate, usage or activity, mix, timing, and unusual events.
- Name the purpose and owner. Clarify what the expense protects or accomplishes and which role can influence it.
- Understand the operating context. Ask what changed in service, volume, staffing, equipment, channels, vendors, or customer expectations.
- Choose the right response. Stop, standardize, renegotiate, repair, replace, invest, reclassify, or consciously accept the cost.
- Return to the result. Verify whether the action improved the system without shifting the problem elsewhere.
A repair expense can tell two different stories
Suppose repairs and maintenance are materially above budget. A narrow expense-control response might freeze nonessential work or pressure the general manager to bring the account back under target. A driver-based review asks which assets required service, whether work was preventive or emergency, how often the problem repeated, what downtime occurred, what maintenance had been deferred, and whether replacement has better economics than continued repair.
The higher expense could reflect undisciplined purchasing. It could also reflect aging equipment, a weak maintenance rhythm, an unrealistic budget, or the delayed consequence of trying to keep last year’s expense low. Those stories require different decisions.
Multi-location businesses make habits easier to see
Comparisons can reveal where systems are consistent and where the business depends on individual improvisation—but only after confirming accounts, allocations, service models, building conditions, and responsibilities are comparable. A reported difference is a starting point, not a conclusion.
The most useful comparisons look for repeatable practices: clear pars, approved vendors, preventive-maintenance calendars, subscription ownership, consistent coding, planned renewal reviews, and a regular rhythm for explaining material variances.
Stewardship is not the same as austerity
Expense discipline matters because resources are finite. But some expenses protect reliability, safety, quality, employee capacity, guest experience, and future resilience. Underinvesting in maintenance, training, technology, or professional support can make the current month look better while transferring a larger cost to the future—or to the people carrying an unhealthy system.
Thoughtful stewardship distinguishes waste from capacity, reaction from care, and habit from intentional choice.
Next, Profit Is the Result, Not the Instruction brings the full P&L together and explains why profitability matters without turning profit itself into an operating instruction.
The P&L does not condemn those choices. It brings them into view. Leadership can use that visibility to reshape the habits behind the result.
