Agricultural entrepreneurship occupies an important place in the themes addressed by Eclosio and its partners. On the ground, it is clear in some places the non-existence of tools for management, monitoring, conservation and/or documentation of the activities of entrepreneurs and also of members of the Village Savings and Credit Association (AVEC). Certainly management tools in paper form have been made available to them, however their day-to-day information is not yet a reality. Most entrepreneurs and VSLA managers have Android cell phones at their disposal. These laptops can be very useful for them in the event of digitalization of the management tools made available to them. It is in this context that the digital application BDev has been set up to facilitate the regular updating of information, transactions or data related to the activities of entrepreneurs and members of VSLAs with an Android laptop. . BDev allows you to fill in and update: stock sheets, the operating account, the physical flow book, the financial flow book, the business plan, the movements of funds within the VSLAs, the financial flow sheet assessment of entrepreneurial capabilities, the entrepreneurial profile assessment sheet.
