Expense Management covers the discipline of knowing what you're spending, why you're spending it, and where you have room to cut without hurting the business. The category is built around two ideas: every expense should map to a category that makes sense for your business, and the difference between fixed and variable costs should drive how you think about every spending decision. Articles cover the standard expense categories most businesses use, the difference between fixed and variable costs and why it matters more than people think, budget planning frameworks small enough to actually use, and cost optimization tactics that don't break the business in the process of saving money. We also call out the hidden costs - subscription creep, expense drift, vendor markup, opportunity costs - that quietly erode margins when nobody's looking. Read this category if your expenses feel out of control, if you're not sure what's reasonable versus excessive for your business, or if you want a clear view of where every dollar is going before the next planning cycle. Pairs well with Financial Fundamentals (so the underlying terms make sense) and Business Forecasting (so cuts and reallocations get modeled before they happen).

Frequently asked: Expense Management
What's the difference between fixed and variable costs?
Fixed costs stay roughly the same regardless of how much business you do (rent, salaries, software subscriptions). Variable costs scale with business activity (raw materials, payment processing fees, contractor work).
What expense categories should every business use?
Most businesses can start with: Payroll, Rent & Utilities, Software & Tools, Marketing & Sales, Professional Services, Travel & Meals, Office Supplies, and Other. Refine from there.
How much should I budget for each category?
Standard ratios vary by industry. For most service businesses, payroll is 40-60% of revenue, rent is 5-10%, marketing is 5-15%. Compare to industry benchmarks rather than absolute numbers.
What are hidden business costs?
Subscription creep (unused software still billing), vendor markup on "included" services, processing fees, opportunity cost of slow decisions, and the cost of customer churn from cutting too aggressively.
How do I cut expenses without hurting the business?
Audit first, cut second. Look at the bottom 20% of every category by ROI (return on investment) and ask if you'd buy it today. Anything you wouldn't buy is a candidate to drop.
