The problem with payroll today

Most payroll software treats pension as an afterthought

Employees don't change their pension contributions because they can't see what it does to their take-home pay. Corrections pile up after payday. And you end up answering the same pension questions over and over.

PayAdjust fixes all three.

Live tax-impact modelling

Employees see exactly what a pension increase costs them

When an employee moves the slider, their net pay updates instantly — showing how tax relief and NI savings offset the cost. The result? Higher contributions, fewer questions.
