Investment services are a wide range of services offered by companies to people who are uncertain of what to do with their money. Some investment services that are offered include advice on stocks and bonds to purchase, methods to free assets for investment, and help with setting up bank accounting systems.
Investment services can be very beneficial to the profitability of your company. Most often in smaller companies the person in charge of the finances is not an investment specialist and may not know all of the tricks that a person in investment services would. Hiring a company to perform investment services for you means that you have more specialized help and advice, while still allowing your current employees to perform the tasks they are most adept at, rather than having them struggle with something they aren't necessarily skilled at doing.
