Evaluating a business for purchase requires looking beyond the headline revenue number to understand the quality, sustainability, and transferability of the earnings. A rigorous evaluation framework protects buyers from paying for value that does not exist or will not survive the ownership change.
Financial Quality Assessment
Review three years of tax returns side by side — are revenues growing, stable, or declining? Are margins consistent or deteriorating? Are there any years where revenue or profit changed dramatically, and if so, why? Request monthly P&Ls to understand seasonality and any within-year volatility. Cross-reference bank statements against reported revenues to validate documentation integrity.
Revenue Transferability Analysis
For each major revenue source, ask: will this revenue still be here after I take over? Customer relationships tied to the current owner are at risk. Contracted recurring revenue is more secure. Industry-standard service agreements are generally portable; personal relationships built over decades by a specific individual are not. Quantify the revenue that is clearly transferable vs. the revenue that is at risk, and price accordingly.
Operations Assessment
Can the business run without you for two weeks? If the seller struggles to answer this question honestly, you should be concerned about what you are buying. Look for documented systems, a capable staff, and operational infrastructure that does not depend on any single person's presence — including your own presence as the incoming owner.
Market conditions — local competitive dynamics, industry trends, regulatory environment, customer demographics — round out a complete evaluation. A business that looks excellent in isolation but operates in a declining market or faces imminent competitive threats requires more careful modeling of future performance.

How to Evaluate a Business for Purchase is a working answer for owners and buyers. We will not invent a statewide average sale price. We will show the earnings math, the Illinois clocks that delay a close, and the questions a serious counterparty will ask.

A simple Illinois close calendar
Plan six to twelve months from cleanup to close on a prepared Main Street deal. Start CBS-1 and any Chicago or Cook notices at letter-of-intent, not the week of funding. Landlord consent often takes longer than the lender.

Questions
No. This is education and planning math. A professional opinion of value is a confidential conversation. We work on a success fee if you engage a sale process. There is no file-upload portal.
Start with adjusted seller’s discretionary earnings, then a vertical planning band. A marketplace average is context, not your quote.
Personal professional licenses do not transfer. Municipal registrations and state notices have their own calendars. Confirm the path before you grant exclusivity.
Most prepared Main Street sales take about six to twelve months from cleanup to close. License transfers, landlord consent, and SBA underwriting add weeks.
CBS-1 is the Illinois bulk-sale notice. File it at least ten business days before an asset transfer that meets the statute. Late filing can put Illinois tax risk on the buyer.
