The prospective buyer of an auto repair shop for sale in California noticed, while conducting Due Diligence noticed that an office assistant was listed on the payroll. But he'd visited the business as a customer and had never seen anyone working in the office.
When inquiring about this, he learned that a "salary" of $1,500 per month was being paid to the seller's sister-in-law, and that she was listed as an office assistant, but didn't actually work at the company.
That's an "add-back" and it should be included with net income the seller said.
The buyer was troubled by this discovery. Also confusing was the seller's assertion that auto expenses, such as gas and insurance charged off as business costs, should be added back to profits.
These are just two examples of the many questions and sources of confusions that can surface when trying to understand the actual costs involved with operation of a business. The confusion comes about because many, if not most sellers attempt to show as little income as possible to reduce the taxes that have to be paid. Then, when it's time to sell, the business owner has the opposite objective, wanting to show as much earnings as possible to justify the price being asked for the business.
The typical way of resolving this dilemma is for the seller to point out the costs charged to the business but not really necessary to operate.
Good examples of these expenses are the owner’s personal expenses paid through the business amongst other items.
