A useful tool of business valuation is the use of "rules of thumb", which are industry driven value approximations. A wide array of rules is applied to almost every type/size of company in existence. As new industries are created, new rules of thumb follow. Today we focus on rules of thumb for service companies.
The great majority are based upon multiples of earnings or adjusted cash flow (ACF) or multiples of annual revenues (AR). Some rules are seemingly irrelevant and others may exclusively determine business value. Accounting/tax practices are valued almost exclusively by multiplying the anticipated AR by between .9 and 1.2. Science turns to art when an attempt is made to choose between a lower multiple and a higher multiple.
Realizing that other factors like down payment, payback terms (interest rate, number of years, collateral, personal guarantee), stock versus asset purchase, training period, FMV of included assets, covenant not to compete and the size of the company's cash flow can impact the final price for a business, application of rules of thumb requires years of skill and experience.
An empirical relationship exists between the amount of ACF and the relevant multiples. For example, a business with $50K in ACF may sell for 1-3 times cash flow and a business with $500K in ACF will sell for between 3-6 times cash flow and a business with $5 million in cash flow may sell for between 6-10 times cash flow (all other things equal). The rules presented here apply to the smaller end of company size with AR up to $1 million and ACF of up to $200K.

15) Pest Control 70%-120% of AR
16) Property Management 5-8 times MR
17) Publisher 3-6 times EBIT or 70% of AR

It is critical to stress that a company's cash flow is ultimately the most important factor impacting business value. Firm specific characteristics also can materially impact valuation results, typically requiring an industry expert to assess their ramifications.
