Small office/home office refers to the category of business or cottage industry that involves from 1 to 10 workers. In New Zealand, the Ministry of Business, Innovation and Employment (MBIE) defines a small office as 6–19 employees and a micro office as 1–5.

An MFP, multi-functional, all-in-one (AIO), or multi-function device (MFD), is an office machine which incorporates the functionality of multiple devices in one, so as to have a smaller footprint in a home or small business setting, or to provide centralized document management/distribution/production in a large-office setting. A typical MFP may act as a combination of some or all of the following devices: email, fax, photocopier, printer, scanner.
