New · Instaroll · Continuous Payroll

Payroll that never
waits for a run.

Calculation starts the moment the pay period opens and updates in real time as data arrives. Your team spends its time reviewing pay - not chasing steps.

Instaroll is a workflow redesign, not a maths one. What you can trust today, you can trust tomorrow.

Closes on the pay date. Reports version. Bank file regenerates.

Pay dates come from the Payroll Calendar. Every report keeps its history, and a late IBAN fix re-emits the bank file - no reopening.

The shift

From stop-and-start to always-on.

Traditional payroll is a series of gates: collect, cut off, process, reconcile, repeat. Instaroll removes the gates. See the difference.

Instaroll: continuous payroll

Data flows in as it happens - from the payroll screen, the employee card, or an integration - and payroll recalculates instantly. You review a live, always-current result and approve when you're ready.

  • Every change recalculates in real time
  • Gross-to-net and variance ready as you go
  • Nothing queues up for a month-end scramble
How it works

The continuous loop

One flow, running quietly in the background from the moment the period opens.

Continuous · loops back
01

Period opens

A run is created and calculation begins automatically - no manual start.

Start
02

Data flows in

Changes arrive from the payroll screen, the employee card, or connected integrations.

03

Instant recalculation

Every input triggers a live recalc. Widgets, payslips and variance update as you watch.

04

Review & approve

Reports are ready. One action approves and locks; the run auto-closes on the pay date.

Finish
Gross-to-net & variance generate automatically once calculation completes - the loop keeps them current.
Simpler by design

Payroll, finally on autopilot.
You just review and approve

The payroll run used to move through seven manual steps. Now the system does the work - a person only reviews the live result and approves it.

What you get

Built for the way payroll really moves.

Everything below runs in the same HR Blizz workspace - no new tabs, no extra tools.

Continuous calculation

Payroll calculates automatically the moment the period opens and never stops keeping up.

Inline edits, live recalc

Add, edit or delete pay data right inside the run - results update instantly.

Dynamic payslip previews

See each employee's payslip as soon as calculation completes, exactly as it will look.

One approval, done

A single approval finalises the run and kicks off your reports - with no chain of separate steps.

Pay dates from the calendar

Pay dates come from the Payroll Calendar you set in advance - no manual entry each cycle.

Everything versioned

Every report is versioned on generation. Nothing is overwritten; the full history is kept.

Regenerate after close

Fix an IBAN and regenerate the bank file after closure - no reopening the period.

AI validations in the run

AI scans the run and flags findings by severity - with the employees involved, so you catch issues before you approve.

No surprises

Same engine.
Same compliance.
New experience.

Instaroll is a workflow redesign - not a rebuild of the numbers behind the run.

The calculation engine is untouched

Instaroll redesigns the workflow, not the maths. Every calculation runs exactly as before.

Statutory rules stay the same

Country rules and statutory logic are unchanged - your compliance position is preserved.

What's new is how you work

Fewer clicks, live results, and one confident action at approval. The change is the experience.

Frequently asked questions

Quick answers to the questions payroll teams ask most.

Instaroll is the redesigned payroll run experience in HR Blizz. It brings the whole run - pay data, calculation, approval, reports and bank files - into a fast, guided flow built around continuous, real-time calculation.

The old multi-step flow becomes far simpler. Inputs are captured and calculated automatically as the run begins, changes recalculate in real time, and finalising is now a single approval. Pay dates come from the Payroll Calendar rather than being entered each cycle.

No. Instaroll is a workflow and experience redesign. The calculation engine, statutory rules and compliance logic are unchanged. What's different is how you interact with the run - not what happens underneath.

From the Payroll Calendar, which your admin configures in advance for the year under Payroll Settings. When a run opens, the correct pay date is filled in automatically - no manual entry each cycle.

The previous multi-step approval has been simplified. Reviews and calculation now happen continuously, so approval is a single, deliberate action that finalises and locks the run - and lets it close automatically on the pay date.

Yes. Reports are never overwritten - every generation creates a new version, and the full history is kept per report type for audit and compliance.

Yes. If an employee's master data changes - for example an IBAN update - you can regenerate the bank file even after the run has closed, without reopening the period. The original version stays intact in history.
