A profit and loss statement shows income, expenses, and the profit or loss recorded over a specific period. For a subscription business, the totals matter—but so do the details behind recurring revenue, refunds, payment fees, and service costs. Review the statement month by month and compare it with the same period last year when possible. Look for changes that need explanation, then check the underlying transactions before deciding whether the numbers reflect a business trend or a bookkeeping issue.
Start with the reporting period
Confirm the dates covered and whether the statement uses cash or accrual accounting. Under cash accounting, income and expenses generally appear when money moves. Under accrual accounting, they may be recorded when earned or incurred. The method affects timing, so avoid comparing statements prepared on different bases. Also check that the books are up to date and that recent bank and payment processor activity has been reconciled.
Compare the current period with the prior month, the same month last year, and your budget if you have one. A single month can be misleading when customers renew annually, promotions shift sales between periods, or expenses arrive irregularly. Note large changes and ask what caused them. A useful review looks for explanations—such as a price change or a one-time bill—not just a higher or lower total.
Check subscription income
Look at how income is grouped. Recurring subscription revenue should be distinguishable from setup fees, one-time purchases, or other services. If several products or plans are combined into one line, ask whether the bookkeeping can provide a clearer breakdown. Separate categories help you see which offers contribute to sales and whether a change in one part of the business is being hidden by growth elsewhere.
Review refunds, credits, discounts, and failed-payment reversals alongside gross sales. Ask whether refunds are rising, whether promotional discounts are reducing the amount collected, and whether processor deposits match the sales records after fees and refunds. A gap may reflect normal timing, but it can also point to missing transactions or a mapping problem. For annual subscriptions, check how your accounting method records payments so the statement reflects the applicable period consistently.
Follow the expense categories
Start with expenses tied directly to delivering the subscription, such as hosting, fulfillment, payment processing, or customer support, depending on your business. These costs can rise as the customer base grows. Compare them with revenue and investigate a sudden increase, a new vendor, or a charge that appears in an unexpected category. Check invoices and processor statements rather than assuming every change is an error.
Then review operating expenses such as payroll, contractors, marketing, software, insurance, and professional services. Look for duplicate subscriptions, annual renewals, spending that lacks a clear business purpose, or costs recorded in inconsistent categories. Ask whether a jump reflects a planned campaign, a hiring change, or a one-time purchase. Correct categorization makes period-to-period comparisons more useful and gives you a clearer view of which costs are recurring.
Turn changes into questions
Check gross profit, operating expenses, and net profit, but do not treat any one total as a complete diagnosis. If revenue increased while profit fell, ask whether discounts, refunds, payment fees, or service costs grew faster. If profit improved, confirm that the result did not come from delayed bills, missing expenses, or a temporary reduction in marketing or staffing. Trace notable changes back to transactions and supporting documents.
Keep a short list of open questions with the period, account, amount, and follow-up needed. For example: Was this software renewal expected? Did processor fees change? Are refunds concentrated in one plan? Resolve bookkeeping errors, then use the cleaned-up statement to discuss business decisions with your accountant or bookkeeper. Steady Ledger helps subscription businesses review bookkeeping details and clarify what their reports show.
A useful P&L review connects each major change to a business event or a verified transaction. Check reporting dates, separate income and expense categories where practical, and investigate unusual movements before acting on them. Make this a regular part of your month-end routine, and ask your bookkeeper to help clarify any line you cannot explain.
