PRACTICAL PLANNING GUIDE
Business Plan Financial Projections: Service Business Example

Business plan financial projections should make revenue, costs and cash timing agree. This narrow service-business example keeps billed revenue separate from collections and debt principal separate from operating expenses. This guide focuses on the operating example named in the title; use it as one supporting part of your wider business plan.
Use the free Service Business Financial Projections to enter your own assumptions, calculate the report and keep an editable backup. No account is needed.
Define what this projection covers
Use a service business with no inventory in this worksheet. Enter consecutive months on their first day and one currency for the whole report. The model compares billed service revenue with incurred operating expenses and noncash depreciation, then calculates cash from actual expected movements.
It does not generate a balance sheet, tax return, inventory valuation or lender package. Use an appropriate accounting review for those needs. The figures below are fictional inputs for learning the workflow, not sector benchmarks.
Keep the operating and cash columns separate
For October, enter $6,000 billed revenue, $4,000 operating expense incurred and $200 depreciation. Modeled operating result is $1,800. Enter $5,000 cash collected and $4,200 operating cash paid separately.
These cash figures can differ from revenue and expense because invoices or bills belong to another period. Include applicable interest in the relevant operating expense and cash-paid figures; principal repayments belong in the separate principal field. Do not deduct the same payment twice.
Reconcile the two-month cash example
Opening cash is $2,000. October collections of $5,000, operating payments of $4,200, principal of $300 and owner withdrawal of $1,000 leave $1,500. In November, $6,000 collections minus $4,000 operating payments, $300 principal and $1,000 withdrawal add $700, giving $2,200 closing cash. November billed revenue of $6,500 minus $4,200 expenses and $200 depreciation gives $2,100 operating result. The two-month operating total is $3,900, while closing cash is $2,200; these answer different questions.
Trace assumptions back to operating work
Break the revenue estimate into clients, jobs or billable units outside the worksheet. Check whether delivery fits the available hours and whether the collection dates match written terms and observed payment behavior. Explain fixed costs from real quotes or agreements rather than a round placeholder. New borrowing or owner capital can increase cash without improving the operating result. Record the source and date behind each assumption in a separate evidence note or dated plan backup.
Run a collection-delay scenario
Keep the base report, then reduce October collections by $1,000 while leaving billed revenue unchanged. October closing cash falls from $1,500 to $500. If that $1,000 is collected in November, increase November collections by the same amount; November closing can return to $2,200. The operating result remains unchanged in this simplified timing test. Month-end balances still hide shortages within a month, so inspect the weekly cash forecast before committing a payment.
Questions about financial projections
Is the lowest month-end cash the minimum bank balance? No; a midmonth payment can create a lower balance. Are owner withdrawals operating expenses here?
No; the model deducts them only from cash. Can I use this for a shop with stock or a loan application? The worksheet's narrow scope is insufficient for inventory accounting or a complete financing submission.

Keep a version you can review

CSV is a calculated report; Print / Save PDF produces a browser print copy. Device saving does not provide cloud synchronization. A static PDF needs its own annotation and backup workflow.
