A three-statement model connects the income statement, balance sheet and cash flow statement so the company’s results, financial position and cash movement agree. It uses actual results to explain what happened and explicit assumptions to test what could happen next.
Three views of the same company
| Statement | The question it answers |
|---|---|
| Income Statement | What did we earn during the period, and what did it cost? |
| Balance Sheet | What do we own and owe at the closing date? |
| Cash Flow Statement | Why did cash change between the opening and closing dates? |
The model also uses schedules for items such as receivables, equipment, debt and owner payments. Those schedules connect the statements; they are not extra independent versions of the plan.
For example, a sale on credit can create revenue and a receivable before it creates cash. Buying equipment can use cash now while its cost reaches profit over time through depreciation. A distribution reduces cash and equity without becoming an income-statement expense.
Historical results and forecasts have different jobs
Actuals are recorded results for completed periods. A forecast projects future results from assumptions. Keep the historical cutoff, opening balances, company scope and model edition visible. A forecast assumption should have a source or be labeled as an open estimate.
The annual budget sets an adopted comparison. A later forecast can change without silently replacing that comparison. Annual budgeting develops the coming year; the five-year forecast tests its longer-term consequences.
A model that balances still needs review
Matching cash and balanced statements are necessary checks. They do not prove the records, classifications, formulas or business assumptions are correct. A hidden borrowing assumption can make the math work while concealing a funding problem. Negative projected cash is a warning to resolve, not a number to erase with an unexplained adjustment.
Review source balances, monthly movements, formulas and the operating story. Have a qualified reviewer accept the financial use of the completed model. Template availability and a worked example do not replace that review.
Use it in the Playbook
Milestone 10 develops the ongoing financial model and monthly practice. The Numbers section of the Owner’s Playbook holds dated outputs; monthly, quarterly and annual reviews use them to make decisions. Keep one maintained financial source behind those views.
