How it works

Five steps from documents to signed timesheets.

01
Project info

Upload BSFZ approval or enter manually. AI extracts every field.

02
Employee data

Merge payroll, vacation, sick leave, contracts — from any format.

03
Generate

Realistic hours per weekday, holidays and entry/exit respected.

04
Validate

Automatic checks for math, holidays, R&D%, entry dates.

05
Export

Excel, PDF, or one ZIP with every employee.

Audit-defensible

Realistic distributions with no obvious patterns. Every hour tied to weekdays, holidays and leave.

Your template, untouched

We never rename sheets, change formulas or reformat cells. Only editable cells are filled.

AI that asks

Missing an entry date? A vacation total? The assistant surfaces gaps — never invents them.
