Initial situation

In regional contract farming - also called solidarity farming or community-supported agriculture - consumers receive regional and seasonal vegetables at a fair price in return for a long-term purchase guarantee. The operational processes of the initiatives are complex and the administrative procedures are considerable. The regional contract landscape in Switzerland consists of approximately 60 initiatives.


The initiatives of regional contract farming are supported by a modern, generally available and source-open software to manage the administrative tasks and can thus reduce the administrative costs.


OpenOlitor is a modern web application for the administration of contract farming processes. With OpenOlitor, master data can be managed, orders can be administered, deliveries and harvest distributions can be planned, invoices can be created or work assignments can be organized. OpenOlitor is developed in the Scala programming language and AngularJS is used for the display layer. To ensure that OpenOlitor can be freely used and further developed by all interested initiatives in the future, OpenOlitor is published under the open source license AGPLv3. More info:
