The year 2018 had been fantastic for our just plan it production scheduling software. We again more than doubled our number of customers paying for just plan it. In our assessment, by this we definitively reached the milestone that software companies call "confirmed product/market fit". This typically is a milestone at which you start thinking about growth and scale. Well, among others "scale" then translates into "more automation". In that regard, we already made a lot of hidden changes to the just plan it architecture in 2018 to allow a more seamless and continuous deployment of product enhancements and bug fixes into the live system. However, what we still kept manual (before getting product/market fit confirmed) was billing and payments. Time to change this.
