Revenue and expenses
Categorize your top income and expense lines.
Categories make reports readable. Without them you have a list of transactions; with them you have a management tool. Use a short chart of accounts: revenue by product line, direct costs, payroll, occupancy, marketing, software, professional fees, other. Eight categories beat forty. Categorize weekly. A year of uncategorized transactions is how tax season becomes a crisis. A common mistake is creating categories to match how the owner thinks about the business instead of how decisions actually get made. Someone adds a category for every vendor name, ending up with dozens of near-duplicate lines that make the report unreadable. Categories should answer a question you actually ask, like "what am I spending on marketing" or "how much does payroll cost," not simply list who got paid. To decide if a category is worth keeping, ask whether a different number in that category would change a decision you make. If knowing you spent more or less on "office supplies" never changes what you do next, fold it into a broader category like "other." Categories exist to guide action, not to satisfy a completeness urge, and fewer well-chosen categories beat many barely-used ones. You will know your categories are working when you can glance at the report and immediately spot something worth investigating, a category that jumped, or one that looks too low for the season. If every review leaves you confused about what the numbers mean, the categories are probably too broad, too narrow, or inconsistently applied from month to month, and it is worth resetting the chart of accounts. A small print shop tracked expenses under forty different labels for two years, and every tax season took a full weekend to sort out. Consolidating down to eight categories, revenue by product line, direct costs, payroll, occupancy, marketing, software, professional fees, other, cut that sorting time to under an hour and, as a side benefit, revealed that software costs had quietly tripled without anyone noticing.
