Business managers typically handle the day-to-day duties of running an office and overseeing its finances. An assistant business manager works alongside the business manager as a subordinate, executing the various office details delegated to them. The business manager typically utilizes the assistant business manager to execute written and email correspondence. The assistant business manager also follows up on the implementation of purchasing and leasing negotiations. The assistant may also need to network with field employees and accounts departments to help provide the business manager with an accurate picture of cash flow within the organization.
