Quick answers
Frequently asked questions
Why should I evaluate my own time?+
This makes it clear whether a small saving of money costs a lot of evenings or weekends.
Does Wertify recommend what work I should do myself?+
No. The tool compares effort. Safety, regulations and your own skills must be assessed separately.
