Need simple accounting system in ASP.net core net6 standard - Spanish requiered

We are extending our existing online platform developed in ASP.net core net 6 standard together with a MySQL database. The first extension will be an accounting system, with the possibility of even more extensions in the future. The system should have all standard accounting functionality like all existing accounting platforms. We are a non-profit organization operating in Costa Rica, meaning we are receiving grants for specific projects that can only be used for that specific project. Current accounting systems don't provide the possibility to account for specific projects. This is the difference that needs to be reflected in the system that we're using. If you already have an existing accounting system, that can be adapted, very welcome. The system has to be in spanish, so if you have at least basic understanding in spanish, would be best as the project definition comes in spanish as well.
