What I like most is how quickly projects can be estimated. With drag-and-drop, you can put together a quote in just a few minutes, and the whole thing doesn't feel like a clunky ERP system. I also really like the controlling features: you can see at any time how actual costs are tracking against the estimate and whether a project is going off the rails. Plus, there are integrations with tools like Personio, awork, and DATEV, and the support team is always friendly if you ever run into a snag.

Previously, we managed estimates and project figures in Excel spreadsheets and other tools, which quickly became disorganized and prone to errors. With this software, we have quotes, budgets, and actual costs all in one place and can see exactly where a project stands financially at any moment. This saves us a lot of time on estimating and prevents any nasty surprises at the end of a project.

The enormous simplicity of OS/ - it didn't take a day to familiarize ourselves with it and set up the relevant employee accounts. This simplicity has enabled us to ensure that everyone tracks their project times properly and that we can keep track of our project performance. The support is also incredibly fast - questions are answered in no time at all, even at the weekend.

Many providers try to pack everything into a single solution, which makes them cumbersome and causes them to lose their clear identity. OS/ maintains a sharp focus that is constantly optimized to meet customer needs. Our contact person, Julia, also gets up to speed on our processes incredibly quickly and provides helpful hacks. Features that aren't yet part of the solution are added to a roadmap, allowing us to actively help shape development in a way that works for us.

OS/ gives me an instant overview of where my projects stand financially. Calculating budgets, tracking time as money, and issuing invoices—everything is in one place with a modern, fast interface. The integration with awork works particularly well, allowing project planning and financial management to mesh seamlessly. The support team is quick to respond, and you can tell that the software is constantly being improved.
