Context: Working as a Software Developer (Hourly Paid).
I did a project analysis on a certain project and came up with the "Software Development Proposal" Document for Company A.
Time spent Analysing the project for Company A: 40 Working Hours
Now, I am working in company B, they want me to analyze a project for the company. While working on this project, I realized that the process was very similar to Company A's project, which saved a lot of time and effort.
Time spent Analysing the project for Company B: 15 Working Hours only.
(Note that no copyright or protected material were used from Company A when analyzing the project for Company B)
Should I get paid for the hours spent only doing Company B's project, or Should I also add the number of hours spent doing Company A's Project?
