That sounds like a very useful application for anyone working in construction or related fields. The Labour Calculator seems to offer a comprehensive set of features to help with the management of labour rates, daily advances, and attendance.
Some of the features that I understand are included in the application are:
Calculating labour rates for different types of work
Managing labour attendance, including tracking who is present and who is absent
Recording daily advance amounts for each worker
Adding multiple construction sites and managing labour for each site
Tracking labour advances and balances for each worker on each site
Providing detailed information about labour advances and balances for each site
These features should help construction workers and managers to easily manage their labour expenses and track their costs for each project. It's great to hear that the Labour Calculator is now available for free, which should make it more accessible to people who could benefit from it.
It would be helpful to know more about how the Labour Calculator works, and what kind of user interface it has. It would also be useful to know where it can be downloaded.
