Payroll Automation

Payroll that runs itself. Accurately. Every time.

Payroll is repetitive, deadline-driven and unforgiving of mistakes. I automate the whole cycle, from pulling hours through approvals, tax filing and payment, so it runs the same way every period without anyone doing it by hand.

This is the process where automation pays back fastest, because the work is high-volume, entirely rule-based, and an error costs real money and real trust with your staff.

Why it hurts

The most repetitive job in the business

Payroll has every characteristic that makes a process worth automating, and one that makes it urgent.

It runs on transcription

Hours come from a time-tracking tool. Someone exports them, opens a spreadsheet, checks them, adjusts for leave and overtime, then types the result into a payroll system. Every transcription step is a chance to transpose a digit, and nobody notices until an employee does.

Deadlines do not move

Tax filings and payment dates are fixed. If the person who runs payroll is ill, on leave, or simply busy, the deadline arrives anyway. A process that depends on one person remembering is a risk, not a system.

A caveat worth stating: I automate the process around payroll, connecting your systems and removing manual steps. I am not a payroll bureau or a tax adviser, and calculations remain governed by your payroll provider and your accountant.

What gets automated

The whole cycle, end to end

Every step below currently costs somebody hours each period.

🔢

Hours and calculations

Hours pulled directly from your time-tracking system, with overtime, leave and adjustments applied by rule. No spreadsheet, no manual maths, no transcription.

✅

Approval routing

Payroll routed to the right manager before it processes, with reminders as the deadline approaches and a clear record of who approved what and when.

🏦

Filing deadlines

Submission deadlines handled by the system on schedule rather than by a person who might be away, with escalating alerts if anything is outstanding.

💰

Payments

Payment files generated and confirmed for every employee on schedule, with retry logic and immediate alerting if any individual payment fails.

📄

Payslips

Payslips generated and emailed to each employee automatically every period, with a portal link to their full history so nobody has to request one.

📈

Accounting sync

QuickBooks, Xero or your accounting system updated automatically with journal entries every run, so the books are current without a month-end reconciliation scramble.

How it works

From manual run to hands-off

Payroll is the one process where I insist on running in parallel before switching over.

01

Map your cycle

I document exactly how payroll runs today, including the exceptions and special cases nobody wrote down.

02

Connect systems

Time tracking, HR, payroll provider, banking and accounting wired together with the right permissions.

03

Run in parallel

The automation runs alongside a real manual cycle and the outputs are compared line by line. Nothing switches over until they match exactly.

04

Go live supervised

The first automated run is done together, with the manual fallback ready and unused.

05

Monitor

Alerting on every failure path, plus 30 days of support covering at least one full cycle.

Engagement

What this costs and what it returns

Build cost

Fixed price after discovery. Most small and mid-sized payroll automations are one to three weeks depending on how many systems must connect and how unusual the rules are.

Running cost

Your existing payroll, accounting and automation platform subscriptions. Usually nothing new, since this connects tools you already pay for.

The return

Easy to calculate: hours per cycle times twelve, plus the cost of the errors you currently correct. Most clients see it clear the build cost within a few months.

Common questions

Payroll automation, answered honestly

No. I connect and automate the process around whatever provider you already use. Your provider still handles the statutory calculations and filings; I remove the manual work of getting data in and out of it correctly.
It is safer than the manual process, provided it is built properly. Automation does not transpose digits or forget a deadline. The safeguards that matter are parallel running before switchover, validation on every figure, approval gates before money moves, and alerting on every failure path. All of those are standard in my builds.
It is designed so a mistake is caught before money moves. Totals are validated against source hours, anomalies outside expected ranges are flagged for human review rather than processed, and a person approves the run. The automation prepares; it does not unilaterally pay people.
No, and you should be cautious of anyone who says they do as a side offering. Statutory calculation and filing stays with your payroll provider and your accountant. I automate the data flow, the approvals, the reminders and the record keeping around them.
Time-tracking tools, HR systems, payroll platforms, banking exports and accounting software including QuickBooks and Xero. If it has an API, webhooks or a scheduled export, it can almost certainly be connected. I confirm on the call before quoting.
Usually one full cycle in parallel, then one supervised live run. So for monthly payroll, expect roughly two cycles before it is genuinely hands-off. I would not recommend rushing that.
Handled by rule, because it is a normal case rather than an exception. Starters, leavers and pro-rata calculations are mapped during scoping. Genuinely unusual cases are flagged for human review instead of guessed.
Yes, and they should. Automation handles the routine run and the payslip delivery. Questions still reach whoever owns payroll in your business, and now that person has time to answer them.
