Tracking income and expenses is not primarily an accounting task — it is a management habit. When you know how much money is coming in, how much is going out, and where each flow originates, you can make better decisions about pricing, staffing, and investment. Start with a simple spreadsheet or a basic records book: one column for income, one for expenses, one for the category, and one for the date. Record every transaction on the day it happens rather than trying to reconstruct a month at the end. Group expenses into a few broad categories — supplies, transport, software, professional services, and miscellaneous — so you can see at a glance where money is going. Keep receipts for every expense, even small ones, because they support your records if questions arise later. Review your income and expense summary at the end of each month and ask three questions: Is income on track compared to last month? Are any expense categories growing unexpectedly? Is there a gap between what I earned and what I have in my account, and do I know why? These simple habits make tax time faster, help you spot problems early, and give you the numbers you need to make real decisions rather than guesses.
