ATOSS vs GFOS

ATOSS

Terminals, smartphones, tablets, PCs and till systems as capture channels, group bookings for mobile work crews, and corrections that are quickly possible and traceably documented cover desk, deskless and field staff well. We found no public information on offline capture or GPS and geofenced check-in, which keeps it short of the top band.

GFOS

The terminal app turns a shared tablet into a clock with PIN or QR login for several employees on one device, stores data locally during network outages, and the phone app adds GPS capture with explicit activation, while stationary time clock terminals are referenced as the classic option — that covers desk, deskless and site crews in one family. Bookings can be corrected afterwards through a stated process, but we found no public information on an approval step or a trail showing who changed what, which is what separates this from the best.

ATOSS

Gesetzkonforme Erfassung and EuGH-compliant documentation are stated plainly, time evaluation runs automatically by defined parameters, and rest period requirements and overtime thresholds are applied, with approvals and correction tracking claimed for audit readiness. We found no public information on configurable break rules, warnings on the daily hour maximum, a retention period, or an export built for an inspection.

GFOS

The recording machinery is rich — overtime and absences flow into wage types, collective and works agreements sit in the rules, sickness cases are differentiated — but that is payroll plumbing, not the statutory record itself. We found no public information on break rules, warnings on daily maximum hours or the eleven-hour rest period, retention of the working-time record, or an export built for an inspection; the closest statement is a general claim about complying with working time regulations in a healthcare context.

ATOSS

Absence requests through defined electronic approval workflows with self-service balances, a shift exchange marketplace, replacements and last-minute plan changes, plus real-time staffing level determination, go beyond basic planning. We found no public information on automatic entitlement and carry-over, sickness recording, per-location holiday calendars, or coverage warnings before a plan is published.

GFOS

Entitlements are monitored with configurable capping on remaining leave, sickness is differentiated into initial, follow-up and work-accident cases, the electronic certificate of incapacity is retrieved via certified GKV communication, and the roster side has availability doodles, shift suggestions matched on time model and qualification, a duty exchange platform and planning-conflict alerts. We found no public information on public-holiday calendars per location, pro-rata entitlement or rest checks inside shift templates, so it sits a notch below the top tier.

ATOSS

Project times and direct booking to cost centres on the go is genuine allocation structure, slightly more than a single project field. But for an agency billing forty people this is the whole story: we found no public information on rates, a billable flag, per-project reporting, budget warnings, or an export the invoicing system would take.

GFOS

The structure is right for a services firm: projects, sub-projects, tasks, locations and cost centres, a billable flag, an activity monitor for logging in and out of tasks, automatic deviation messages when tracked hours and project bookings disagree, and evaluated project times transferred onward "for invoicing, for example". But my margin lives in rates and budgets, and we found no public information on rate cards by person, role or project, currency budgets with overrun warnings, or client-facing reports — so a month still could not be billed from these pages alone.

ATOSS

A named DATEV technology partnership covering ATOSS Time Control and the Staff Efficiency Suite, automatic transfer of all data to the payroll system, automatic pay rule application with discrepancies flagged before payroll, approval escalation ahead of deadlines, and corrections handled after initial processing amount to a maintained integration with retro handling. We found no public information on night, Sunday and holiday surcharge detail, time accounts, or a formal lock step before transmission.

GFOS

Certified interfaces to DATEV, PAISY, SAP, LOGA and VEDA plus 24 other payroll systems, night, Sunday and holiday premiums calculated automatically from recorded times, monthly payroll data preparation at the touch of a button, test payrolls and integrated retroactive accounting — that is a genuine handoff rather than retyping, with absences synchronized to downstream systems on change. The one piece we found no public information on is a lock step before transmission.

ATOSS

A German contracting entity, ATOSS Software SE in Munich with the register entry to prove it, a DPA linked in the footer, and a choice of cloud or on-premises deployment give me a European counterparty I can name. We found no public information on where cloud data is hosted and no subprocessor list, so the chain above that German entity stays unevidenced.

GFOS

A German contracting entity in Essen with a German register court and VAT number, ISO 27001 certification and Made in Germany positioning — that is who I want to sign with. But we found no public information on where the product's data is hosted or on its subprocessor chain; the published privacy policy covers website tools, including HubSpot with storage in Germany and the USA on an Art. 49 GDPR basis, rather than the time-tracking platform itself.

ATOSS

Nothing on the captured pages carries a price: no per-user figure, no module price, no billing period or minimum, only named modules and an invitation to schedule a demo. A forty-seat buyer has no way to compute an annual invoice from public information.

GFOS

The packaging is visible — Base, Professional and Enterprise tiers plus separately named add-ons — but we found no public prices at all: no per-user figure, no billing period, and no pricing for terminal hardware, the planning module or the payroll interfaces. Procurement cannot compute an annual invoice for forty heads without a sales conversation.
