Payroll deadlines
Payroll deadlines set the pace of your month: submissions, contribution payments and annual adjustments. This calendar centralises all your payroll due dates so you can plan ahead instead of chasing deadlines. Stay on top of key dates.
HR deadlines
Between performance reviews, mandatory training and leave tracking, your weeks are already full. Rather than keeping it all in your head, sync these HR deadlines with your calendar and take back control.
Mixed deadlines
The equality index, annual social data reporting and the social report rely on both payroll and HR data. Anticipating these mixed deadlines lets you collect information early and avoid last-minute errors.
