Why OpsCore

A period can only ever produce one payout batch. Once paid, it cannot be unlocked — reversing it means deleting the unpaid batch first, and that action leaves a trail.

Closed payroll is stored as a snapshot. Reports, payslips and backups read from it rather than recomputing — so last year’s numbers are still what they were on closing day.

Duplicates within one Excel file, against a previous import, and against paid leave days are all blocked, and the number of merged rows is reported rather than hidden.

Who changed what, when, and what the old value was — recorded automatically for every business table, not dependent on a developer remembering to log it.

Admin, worker and partner each get a separate interface with separate logins. A partner sees only their own unit, because scope comes from the session rather than from the browser.

Social, health and unemployment insurance with configurable rates and caps; progressive personal income tax; regional minimum wage; severance that nets off insured months correctly.

Each closed period exports an immutable Excel package - payroll, per-day detail, employer-borne cost - so accountants, auditors and inspectors can reconcile without being given system access.

Raise a rate mid-month and only the days from that date onward use it. The whole month is never repriced, and the first ten days never lose their rate.

Paid leave adds to income, unpaid leave deducts, and requests touching a closed period cannot be edited - so the payslip never disagrees with the leave ledger.

Tenure measured across the continuous contract chain, netting off months already covered by unemployment insurance, and counting unpaid drafts so a second claim cannot be raised for the same span.

Not "admin or not": every action is its own permission, granted by role. When one is missing the system names it rather than returning a generic error.

Payslips, leave decisions and attendance reminders reach workers directly - and every send is logged with who, when and whether it succeeded, so "I never got it" has an answer.
