LiquiMinder
Your invoices and liquidity, always in view.
LiquiMinder is a desktop application for micro-business owners and small teams - from freelancers, photographers, and musicians to local trades with just a few employees. Keep incoming and outgoing invoices, offers, reminders, and key figures in one place, stay on top of your liquidity, and work directly on your local computer. It is not accounting software, but a clear invoice manager with offers, controlling, and simple customer management.

Pricing - Fair & Transparent
We believe in fair pricing without surprises. LiquiMinder is a one-time purchase - you pay once and use the base application forever, with no forced subscription. LiquiMinder runs fully locally on your computer, so your invoices, Word and Excel documents stay on your device and don't require an internet connection to work. Our license model is pay what you need: start with the base system and add only the modules you actually use.
