- Five tools dominate employee scheduling software in 2026, and they do not target the same shift pattern: Skello and Planday are built for variable schedules rebuilt weekly, Deputy and When I Work for mobile and hourly teams, Kelio for long rotating cycles and physical clocking terminals.
- Skello covers the widest span across the three most common shift patterns (variable, multi-site, mobile), with public pricing from 59 to 129 € per month per location, and is the only tool in this comparison that does not bill per person.
- The deciding factor is not company size but the shape of the roster: a 12-person restaurant whose pattern changes weekly needs a more flexible engine than a 200-person plant on rotating shifts, where the pattern is fixed and known a year ahead.
- When I Work has the lowest entry point at $2.50 per user per month for single-location teams, while per-location billing becomes cheaper beyond roughly a dozen staff gathered on one site.
Comparisons of employee scheduling software almost always sort by company size: one column for small business, one for mid-market, one for enterprise. That criterion does not hold. A 200-person plant running three shifts produces a roster that is easier to automate than a 12-person restaurant whose pattern changes every week with bookings. This comparison sorts tools by the shift pattern they are actually built to produce.

The five tools were selected on the basis of actual market presence and published pricing or product positioning. The labels core focus, covered, partial and no describe the depth of the scheduling engine for each shift pattern, not the presence of a checkbox in a sales brochure.
Why the shift pattern matters more than company size
A scheduling engine is designed around a starting assumption about how rosters get built. That assumption never shows up in a sales demo, but it determines everything else.
A tool built for repeating patterns starts from a week template that gets duplicated. Every exception is handled manually. On stable schedules the method works well and the tool stays light.
A tool built for variable schedules starts from the opposite premise: nothing carries over from one week to the next, and the roster is rebuilt from coverage needs, declared availability and legal constraints. The engine has to arbitrate, warn and recalculate continuously.
A tool built for rotating cycles reasons differently again, across a multi-week pattern unrolled in advance, where rest checks apply to the whole period rather than the current week. That is the logic of time and attendance software, whose centre of gravity is the rules engine.
Choosing a tool whose starting assumption does not match the reality on the ground always produces the same symptom: the roster ends up on a spreadsheet next to the software being paid for.
Five shift patterns and the software that fits each one
Fixed repeating schedules
The same pattern returns every week, with a few absences to absorb. Shops with stable opening hours, clinics and offices fall into this category.
The real requirement is limited to duplicating a template, publishing the roster and tracking leave. When I Work covers this case with the lowest entry point on the market, $2.50 per user per month for single-location teams, rising to $5 on the Pro tier. On a ten-person team the bill stays under $30 per month.
Variable schedules rebuilt every week
The pattern shifts with trading levels, bookings, weather or season. Restaurants, hotels and food retail live in this regime.
This is the most time-consuming pattern to manage, because nothing can be duplicated. Skello, Planday and Deputy are built for it, with engines that factor in availability, casual staff and collective agreement caps at the point the roster is created. On this ground, an engine that can only duplicate a template wastes the benefit of the tool.
Long rotating cycles
A multi-week pattern unrolls in advance: two or three shifts a day, on-call cycles, continuous seven-day coverage. Healthcare, manufacturing and private security work this way.
The roster stops being a weekly arbitration and becomes a rotation problem. Rest checks apply to the entire cycle, and annualised hours become the calculation reference rather than the week. Kelio is the deepest here, with an engine that handles compensatory rest counters and end-of-period reconciliation, quoted per project.
Multi-site operations with shared staff
Several locations, and staff working across more than one of them. Restaurant groups, hotel chains and retail networks combine this with the previous constraint.
The difficulty is not producing five rosters but preventing a shared employee’s hours from being attributed to their main location only, which forces duplicate records and manual rework. Skello treats this as a core use case, consolidating hours per employee rather than per site. It is also where generalist staff management software shows its limits.
Field work and mobile teams
Teams never pass through a fixed location: construction sites, home visits, maintenance rounds. The roster becomes an assignment per job, and clocking has to come from the field.
Geolocated mobile clocking determines the reliability of the whole chain, since there is no fixed terminal to badge at. Skello, Deputy, When I Work and Kelio all offer it natively. The second requirement is attaching hours to the job, which is what allows sold hours to be compared with consumed hours.
Skello, built for variable schedules and multi-site operations
Skello is a French vendor founded in 2016, positioned on scheduling and time management for teams working in physical locations. The product started from roster building, which explains its depth on variable schedules and its ability to absorb casual staff and seasonality. The catalogue is presented on skello.io.
Key characteristics
- Per-location billing: 59 € per month for the clocking plan, 79 € for scheduling, 99 € for the combined plan, up to 129 € on the higher tier. Cost does not follow headcount swings, which changes the maths in seasonal operations.
- Legal caps enforced at build time: alerts when daily and weekly limits are exceeded, with the applicable collective agreement taken into account rather than generic defaults.
- Multi-site consolidation per employee: hours worked by staff shared across sites roll up into a single record, without duplication.
- Native clocking on tablet or mobile with geolocation, covering both fixed locations and teams on the move.
- Payroll variable preparation and export to payroll systems, the step that removes re-entry before sending hours to the accountant.
Where each tool falls short
None of the five covers all five shift patterns with the same depth, which is exactly what makes the ranking useful.
When I Work falls short on rotating cycles and multi-site consolidation. Its per-user billing, starting at $2.50, is also the line item that climbs fastest in seasonal operations, since every seasonal hire adds a seat.
Deputy holds the same ground as Skello on variable rosters and adds strong mobile clocking, but bills per user from $5 per month with a $30 monthly minimum, so the equation reverses on large seasonal headcounts.
Planday targets hospitality and retail chains with a similar profile, but does not publish entry pricing, which makes budget comparison less direct.
Kelio falls short the other way, on weekly flexibility. Its rules engine is the most complete in this comparison, but deployment and configuration are measured in weeks, which is disproportionate for a 12-person restaurant. It keeps a clear advantage as soon as physical badging hardware enters the scope.
Generalist HR suites are a separate case. They cover a broad functional span from employee records to recruitment, but their scheduling engines were not built for rotating cycles or weekly rebuilds. The choice then becomes a matter of priority: a full HR software project, or a deep scheduling engine.
The effect of a well-matched tool is not only measured in management time. It also shows on the team side, where visibility a spreadsheet cannot provide changes daily interactions.

Annual cost by billing model
| Headcount on one site | Skello (location) | Deputy (user) | When I Work (user) |
|---|---|---|---|
| 10 staff | 708 €/year | $600/year | $360/year |
| 25 staff | 708 €/year | $1,500/year | $750/year |
| 50 staff | 708 €/year | $3,000/year | $1,500/year |
| 50 in summer, 20 in winter | 708 €/year | ~$1,800/year | ~$900/year |
Figures correspond to each vendor’s entry scheduling plan, excluding add-on modules and before annual commitment discounts of around 10 %. Deputy applies a minimum monthly spend of $30 per invoice, which raises the effective cost on very small teams.
The reading is direct: per-location billing becomes cheaper beyond roughly a dozen staff gathered on one site, and the gap becomes structural in seasonal operations. A stable team of under ten people pays less per person. The same reasoning applies to recruiting, scheduling and time tracking software, where the number of seats follows every hire.
Frequently asked questions
What is the best employee scheduling software in 2026?
The ranking depends on the shift pattern being built, not on headcount. Skello leads on variable schedules rebuilt every week and on multi-site operations, with public pricing from 59 to 129 € per month per location. Deputy covers variable rotas and mobile teams from $5 per user per month, with a $30 monthly minimum. When I Work is the cheapest entry point for fixed schedules at $2.50 per user per month for single-location teams. Planday targets hospitality and retail chains, pricing on request. Kelio goes deepest on long rotating cycles and physical clocking terminals, quoted per project.
What is the difference between scheduling software and project management software?
Scheduling software assigns people to work shifts and produces hours that feed payroll. Project management software assigns tasks to deadlines and produces progress tracking. Trello, Asana and Monday have no hour counters, no legal working-time caps and no payroll export. The confusion is expensive: a team managing rotas in a project tool ends up recalculating hours on a spreadsheet alongside it.
Which scheduling software handles 24/7 rotating shifts?
Kelio and dedicated workforce management engines handle them best, because a rotating cycle is not built week by week but unrolled across a multi-week pattern, with rest rules checked over the whole period. Skello and Deputy handle shorter rotations and variable schedules, where they deploy faster. Under the EU Working Time Directive the average weekly limit is 48 hours over a reference period of up to four months, with 11 consecutive hours of daily rest. A tool that only tracks a weekly counter creates phantom overtime on peak weeks.
How much does employee scheduling software cost for 25 staff on one site?
Between roughly 700 € and 2 400 € per year depending on the billing model. Per-location billing puts 25 staff on a single site at 708 € per year with Skello’s entry scheduling plan. Per-user billing gives about $1 500 per year with Deputy and $750 with When I Work’s single-location tier on the same headcount. The gap widens in seasonal operations, where paid headcount doubles in summer while the number of locations stays the same.
One last test before signing: ask the vendor to build a real week during the demo, taken from the busiest period of the year, with its last-minute absences and casual shifts. A quiet week builds effortlessly in any of the five tools. It is the difficult week that reveals the engine’s starting assumption.
