Crewline, Attendance, Leave & Payroll Platform

Visit Live Project

Crewline is our own product, a multi-tenant platform that takes a company from the morning check-in to the month's bank file. Employees mark attendance from an installable phone app. HR runs shifts, rosters, holidays, leave and corrections. Payroll moves from draft to calculated, reviewed, approved, finalized and paid, and a finalized run can only be corrected through an adjustment or a reversal, never an edit. It is live at payroll.thesaaspeople.com.

In short

Crewline is a multi-tenant attendance, leave and payroll platform built and run by TheSaaSPeople. Staff check in from an installable phone app that keeps working offline, verified by geofence, office network or a rotating QR code. Late-coming and overtime rules are versioned data rather than code, and every amount on a payslip links back to the attendance day, leave, rule or adjustment that produced it.

Problem and Solution

The Problem

Growing employers often run attendance on a biometric device or a register, leave in a spreadsheet, and payroll in a third tool. Every month someone reconciles the three by hand, the late-coming rule lives in one person's head, and when an employee questions a deduction nobody can show where it came from.

Our Solution

One system in which attendance, leave, rules and payroll share the same data. Check-ins are verified at the source. Policies are versioned and effective-dated, so history is always calculated with the rule that was in force at the time. The payroll engine produces explainable payslips, a bank transfer file and an accounting journal from the same run.
