This answer may vary for different areas of the country, but typically (at least here in PA) the inspection is ordered by the buyer after the seller has signed the Agreement of Sale. This is often called the execution of the agreement.

The Agreement of Sale will define the period of time (often called the "contingency window" or "inspection period") that the buyer has to have the inspections performed, receive the reports, and respond to the seller. In PA, the standard language calls for anywhere from 10 to 15 days, but this can be specifically altered on individual contracts if necessary.

It depends on your business, but if you are a business to consumer such as restaurant, carpet cleaning, plumbing, it brings name recognition to the community. If you kid plays the sport, then you can make friends with the other parents. People call people for services they trust, and then in turn they will recommend you.

Don't expect a flood of business from little league advertising, but friends call friends when in need.
