How accountants and bookkeepers can add payroll services

Most small businesses would happily hand payroll to someone they trust — it’s fiddly, time-sensitive and stressful to get wrong. That makes it a natural fit for accountants and bookkeepers who already hold the client relationship. Unlike a tax return, payroll recurs every pay cycle, so it turns a seasonal engagement into predictable monthly revenue. It also deepens the relationship: once you run a client’s pay, you’re woven into their operations and far harder to replace. And it’s a springboard into higher-value advisory work. If you’re clarifying where payroll sits between the two roles, see accountant vs bookkeeper.

You don’t have to run every client’s pay yourself from day one. There are three broad models, and many practices offer more than one:

RosterElf is built to be the engine behind all three: refer a client and earn commission, monitor their award-compliant pay data, or run the whole cycle from the Advisor Centre. Most practices start by referring, then move clients to managed payroll as confidence grows.

The reason payroll scares people isn’t data entry — it’s modern awards. Penalty rates, overtime, allowances and casual loading vary by award, day and time, and interpreting them by hand is slow and error-prone. Get it wrong and your client faces back-pay and penalties, and your firm carries the reputational risk. This is exactly the problem automated award interpretation solves: pay is calculated against the relevant award automatically, so you’re not translating a rulebook into a spreadsheet every fortnight. Our guide on how AI is changing accounting covers where this automation is heading.

Most practices price managed payroll per employee per pay run (or per month), often with a base fee and a one-off setup. Indicative Australian figures from Bark’s 2026 payroll cost guide:

The firms that make payroll pay follow a simple pattern: standardise the tooling, price it as a package, and let software do the compliance heavy lifting.

Running payroll for clients means owning their compliance. The essentials to have covered:

This is the AU-specific point most overseas guides miss. Payroll activities that form part of BAS services — such as calculating and reporting PAYG withholding, or lodging a client’s BAS — are regulated under the Tax Agent Services Act 2009. To charge a fee for them you generally must be a registered BAS agent (or tax agent) with the Tax Practitioners Board. If you’re a bookkeeper planning to offer payroll as a paid service, BAS agent registration is usually the gateway — confirm your obligations with the TPB before you start charging.

Start small: run payroll for three to five clients first to nail your process and templates, then scale. Use a written engagement letter that defines scope, cut-off times and responsibilities (who supplies hours, by when), so there’s no ambiguity when a deadline is tight. Standardise onboarding — award setup, employee records, pay calendar and integration — into a repeatable checklist, and each new client gets faster. As volume grows, the managed-payroll model and the recurring fees compound.
