We charge 125 Euro per hour for meetings, training & implementation time. The time we need to learn a new skill is on us. In general a project takes 4 - 6 months. The first part is about what you want and involves quite some discussion and clarification. The second part is the implementation and making it easy for the end user. The last part is testing and improvements based on feedback.
Coding Coda is a serious job and takes time. I did a lot of work related to calculations and HRM planning.
