"Attendance" and "time tracking" get used interchangeably, usually by people selling software that only does one of them. They answer different questions and feed different decisions. Here is the difference in plain English, and when each one matters.

Attendance: "are they here?"

Attendance answers a yes-or-no question: did the employee come to work today? It produces a present/absent/late record per employee per day. Used for:

Payroll: basic salary calculation, deductions for absence
Leave reconciliation: does this absence match an approved leave?
Penalty application: late marks, half-days
Compliance: labour-inspection records
Operations: who is on-site today

Resolution: typically daily. Inputs: check-in time, check-out time, optional location.

Time tracking: "what did they spend time on?"

Time tracking answers a different question: of the hours the employee worked, how much went to each project, task, client or activity? It produces time entries per employee per project per task. Used for:

Project billing: bill the client for hours worked
Project profitability: was this project profitable given hours invested
Capacity planning: how much engineering bandwidth went to bug fixes vs features
Estimation accuracy: did we estimate correctly
Resource allocation: should we hire more on team X

Resolution: typically by task / sub-day. Inputs: project, task, start time, duration, optional notes.

The same hours, different lenses

An employee working 9-to-5 produces:

Attendance record: "Present, checked in 9:02am, checked out 5:48pm", one line
Time tracking record: "Project A: 3 hours; Project B: 2 hours; Project C: 1.5 hours; meetings: 1.5 hours", several lines

Both are real and useful. One does not replace the other.

Who needs only attendance

Manufacturing: attendance + shift coverage is the question
Retail: attendance + store coverage
Hospitality (frontline): attendance + shift
Hospital ward staff: attendance + on-call
Office HR / admin / support: attendance is the relevant signal

Who needs both attendance + time tracking

IT services / software houses: bill clients for hours
Consulting: projects, retainers, fixed-fee with effort tracking
Legal: billable hours per client matter
Marketing agencies: campaign-wise effort
Design studios: project-wise hours
Accounting / tax practice: client-wise time

The common mistake

Companies buy an attendance tool and call it "time tracking" because hours since check-in look like time tracking. They are not the same. Hours-on-site does not tell you which project consumed them. For service businesses billing clients by hour, you need actual time entries per task.

The integration that matters

If you need both, the attendance and time-tracking systems must agree on total hours. If attendance says 8 hours and time tracking says 9, someone is wrong. The cleanest integration is one platform where time entries roll up to attendance, not two separate systems trying to reconcile.

Productivity-based attendance: a middle ground

For desk-based remote work, productivity-based attendance sits in between. See: productivity attendance explained. It measures actual active hours (rather than presence), but does not categorise them by project the way real time tracking does.

The Zaffre HRM fit

Zaffre HRM handles attendance natively for all use cases (web, mobile, desktop, face recognition, biometric integration). For service businesses needing time tracking, the project management module captures time entries per project / task, integrated with the same employee records. Both views come from one platform.
