One way a business can grow is to acquire existing business assets. Those business assets might be client lists, existing contracted accounts, intellectual property, trademarks, real estate, income producing assets, capital investments, infrastructure, and so on.
Acquisitions raise a lot of potential risks and benefits. Often there are questions related to the proper valuation of the assets in question, how a purchase will be financed, how the assets will be integrated into the existing business, how roles and authority will change, and much more. The best time to investigate these issues and conduct an evaluation is before any commitments are made. However, this is also often the time when there is the most pressure and emotions involved.
