Vantabill
I've built a few projects that are pain-points of mine and that I dog-food because they work how I want them to and address issues other apps didn't: Vantabill (https://www.codenius.com/products/vantabill/) - I needed to make invoices for the occasional work I completed, but didn't have the budget to pay for a SaaS nor did I want my data to be online on someones server/database. I also disliked that all the other Open Source options out there required me to install LAMP/LEMP or the Node.js stack. So I built this app. It's installable as a single binary on Linux, Windows and MacOS. Your data is never locked into the app (I abstracted the data layer to exist outside the app) and you can go from quote to receipt with simple clicks. The app is totally FREE but I'd love for some other people out there to use/test it. It isn't 'signed', so Microsoft and MacOS will complain, but I'll gladly help anybody set it up. MapBooksCRM (https://www.codenius.com/products/map-crm/) - A very unique app that uses maps to map out your customers (OSM-first). I built it for an HoA, but it can be used for any type of business that requires the ability to track customer details/payments within a defined area. It is equal parts CRM/Accounting software that also provides useful stats to see how your monthly/yearly performance is. Same like Vantabill, this app is completely offline and the data layer is abstracted from the app (no lock-in). I'm hoping to sell this software as 1-time licensed software (pre-SaaS style) and I'd love to give you a demo. Available to chat via email: design@codenius.com
