Missing punch = the worker was on the floor but the machine did not record his thumb. Those days are added to his salary at calculation time.

Daily wage auto-fills from the staff list — override here for this sheet only.

Days accept halves — 0.5, 1.5 and so on. Every day is valued at the daily wage above. Missing attendance is added: the work was done, the machine just did not record the thumb.

Enter how much of his work should go towards reducing the old advance.

Set SHEETS_ENDPOINT in the config block at the top of the script once the Apps Script web app is deployed.

Changes are saved in this browser. Names, wages and advances feed straight into attendance and the salary calculator. The advance column is each worker's opening outstanding balance.
