Reserve call-ups (Miluim) and Shabbat restrictions create planning gaps no generic scheduler is built for. Klacks combines instant, compliant replacement planning with Shabbat-aware autofill.
Miluim orders can pull staff out with almost no notice, tearing holes into security, hospital and staffing rosters.
Under the Hours of Work and Rest Law, Shabbat employment needs a state permit, and employees can refuse it on religious grounds — get the rota wrong and you're both understaffed and non-compliant.
Standard overtime (125%/150%) combines with the 50% rest-day premium when work falls on Shabbat — manual payroll prep is error-prone.
Klacks runs on-premise on your own infrastructure — ready in minutes via Docker.
Public holidays, surcharges and rest periods come preconfigured for your country — and you can adjust them anytime.
Klacks builds shift plans, flags conflicts and optimizes routes — with an AI assistant if you want.
Israel has no cantonal or regional holiday layer the way other countries do — the legal variety runs along religious affiliation instead, and in Jerusalem even along an ancient walled-city privilege. Klacks captures exactly what purely geography-based tools miss.

Crisis-resilient rostering, not a generic 24/7 planner.
The moment a reservist is called up, the Recovery Engine finds the best qualified stand-in from your pool — without touching the reservist's own contract data.
Staff mark their Shabbat availability once; the autofill engine reliably excludes them from Shabbat shifts from then on.
Klacks' typed surcharge engine applies the combined overtime + rest-day premium so payroll gets accurate figures, not manual guesswork.
Calendar rules handle the Friday/Saturday week and Shabbat start/end times natively.
Klacks already exports hours, overtime and allowances to CSV/Excel; a Hashavshevet-compatible format is next on our roadmap.
Before a schedule change goes live, you can run it as an isolated copy first — rest-day premiums and Shabbat rules get recalculated exactly as they would in the real schedule. Only once everything checks out do you promote that version; until then, your live roster stays untouched. That way you can prepare a ready-to-go scenario in advance for situations you can see coming — a reserve call-up, a sick call-out, or a demand spike — and switch to it instantly when it happens, instead of improvising under time pressure. There's no artificial cap either — create as many scenarios as your planning needs.

Klacksy isn’t a bolted-on marketing chatbot — it’s embedded directly in the Klacks interface. Staff and schedulers ask about shifts via chat, request shift swaps, or resolve qualification conflicts within the team. A built-in skills and rules system ensures Klacksy only ever suggests changes that actually match the qualifications and working-time limits of the people involved.
