Which modules are you? ©
Techlog is designed in a modular fashion and companies or users can choose the ones to which they want to have access. Users have the ability to condition the menu system used in Techlog to suit their own working style. Unused functions can be hidden; used functions can be grouped just the way you like. Customised systems can be saved at Company, Project or User level. There is a licensing strategy that is easy and flexible. Pick and choose modules to suit your needs.
