See our background

Is your team still handling leave through messages, spreadsheets and memory?

Leave records are hard to track

  • Leave requests are split across WhatsApp, verbal updates and different forms
  • Without formal records, month-end checking can create disputes
  • Admin needs one place for leave reasons and supporting documents

Are leave requests still scattered across WhatsApp messages and verbal updates?

Leave records are hard to track

Annual leave calculations go wrong easily

  • Different start dates make pro-rata leave easy to miscalculate
  • Carry-forward and first-year leave rules need clear logic
  • Manual Excel formulas increase admin and compliance risk

Are start dates, pro-rata leave and carry-forward rules still calculated in Excel?

Annual leave calculations go wrong easily

Leave balances are not transparent

  • Employees often ask about remaining leave balances
  • Admin staff repeatedly check spreadsheets to reply
  • Without self-service access, long-leave planning and staffing become harder

Do employees still need admin staff to check their remaining leave balance?

Leave balances are not transparent

How leave management becomes clearer

Mobile leave approval

Employees choose leave dates and upload proof on mobile, while managers receive notifications for quick approval.

Mobile leave approval

Automatic leave balance calculation

The system calculates annual leave by start date and company policy, reducing manual errors.

Automatic leave balance calculation

Employee self-service leave view

Employees can check used and remaining leave themselves, so admin teams answer fewer repeat questions.

In 2026, does leave management also need fuller HR support?

More leave management tools for teams, records and policy rules

Team roster overview

Show who is already on leave during approval, so managers can avoid staffing gaps.

Digital sick leave proof

Let employees upload sick leave certificates, with records stored for review and audit.

Public holiday rules

Built-in Hong Kong holiday rules help leave calculations exclude non-working days correctly.

TOIL and overtime leave records

Record time-off-in-lieu after approval, so overtime leave balances are clear.

Leave report export

Export monthly or yearly leave summaries for payroll, accounting and internal review.

Flexible leave policy settings

Configure carry-forward, unused leave payout and other company-specific leave rules.

Leave management may look small, but repeated balance checks, approvals and records quickly drain admin time. A clearer system helps managers focus on actual team planning.

After launch, where will HR workflow improvements become visible?

Measure results through leave records, approval time and balance calculation

Automated calculation reduces manual input errors and helps teams manage leave records more consistently.

HR Compliance Audit

Self-service leave access helps employees understand balances and policies without repeated admin checks.
