The volume of trade on the Internet has increased steadily in recent years. It is becoming increasingly easier to order products or services from around the world with just a few clicks of the mouse, but also to offer them to customers. This development brings with it a number of opportunities but also risks for small companies that already sell electronics products in a niche via the Internet.This thesis explores the development of a process model that can be used by companies that already sell electronics products in a niche via the Internet to further develop the existing business model or, if necessary, to realign it completely. The existing literature on business models, business model development processes and design patterns is reviewed and the current developments and trends in online trade and the electronics sector on the business model of companies trading with niche product is analysed. The business model development process derived from a theoretical perspective is put to practical use by applying the model on a reference company. This implementation includes a multi-stage process with an in-house workshop, gathering and evaluation of lots of data and interviews with experts. Twelve business model variants are found, of which six are checked by experts for practical suitability after pre-selection. The results are two detailed business model designs. The first business model "Multilingual Offerings" is to be seen as an extension of the existing business model and deals with the enlargement of the customer base of the existing business through multilingual product offerings. The second business model "Fever Screening Thermal Solution" represents a completely new business model and describes the development of a system for the exact contactless measurement of body temperature with the help of thermal imaging cameras.
