Outsourced finance function vs in-house hire: real costs
Salary versus monthly fee. That's the comparison almost every owner makes, and it's the wrong one. What actually matters is the total cost of each option measured against the capability you get for it. An employee's salary is the visible slice of a much bigger number, while an outsourced function trades some day to day presence for breadth of skill and continuity. Below is the full cost picture, so you can compare honestly for wherever your business sits right now.
The true cost of an in-house hire
Owners anchor on the advertised salary almost every time. The real cost to you as the employer runs materially higher once you add super guarantee at 12 percent of ordinary time earnings, leave entitlements and the cost of covering them, workers compensation premiums, payroll tax where your wage bill clears your state's threshold, software, equipment, training and recruitment. Then there's the cost that never shows up on a payslip: your own time spent managing, reviewing and quality checking the work.
There's a capability ceiling too. One person carries one skill set. A bookkeeper level hire might be excellent at transaction processing and out of their depth on payroll edge cases, entity structures or management reporting. Go the other way, a senior finance manager, and it's expensive, and they'll spend much of their week on work well below their pay grade. Small businesses rarely have a full time role that matches one person's skills edge to edge.
The true cost of outsourcing
An outsourced finance function charges a fee, typically fixed and monthly, covering an agreed scope: transaction processing, payroll, reconciliations, compliance lodgements and management reporting, with senior review built in. The fee's the headline number, and an honest comparison includes what sits around it: your own time providing information and answering queries, any software billed separately, and fees for out of scope work like one off projects or rescue jobs.
The structural advantages sit in continuity and breadth. You're buying a team, so leave, resignations and sick days stop being your problem, and someone senior reviews the work as a matter of process, not as a favour. The trade offs are real too: nobody's sitting in your office, response times run on an agreement rather than proximity, and a poor provider can hide behind process just as easily as a good one demonstrates it. Scope discipline matters here; anything outside the agreement costs extra, so make sure the agreement reflects how your business actually runs.
Comparing the options honestly
| Factor | In-house hire | Outsourced function |
|---|---|---|
| Visible cost | Salary | Monthly fee |
| Hidden costs | Super, leave, workers comp, payroll tax, software, training, recruitment, your own time managing it | Out of scope work, software billed separately, your time answering queries |
| Skill coverage | One person's skill set | A team spanning processing through to senior review |
| Continuity | Leave and resignation create real gaps | Provider covers absences internally |
| Oversight | You review the work, or nobody does | Senior review built into the process |
| Presence | In your office, absorbs ad hoc tasks | Remote, works to an agreed scope |
| Scaling | Step change; each hire is a big jump | Scope adjusts as the business does |
How to decide for your business
- Under roughly full time volume of finance work, outsourcing usually wins on cost and capability, since a full time hire spends part of the week underused
- If your need spans levels, transaction processing plus management reporting plus payroll expertise, a team beats any single hire you could make
- If your business genuinely needs a daily on site presence handling operational tasks beyond finance, an employee might fit better
- A hybrid is common and perfectly legitimate: an in-house administrator for daily operational work, with an outsourced function behind them for payroll, compliance and reporting
- Whatever you choose, write down the scope, the review process and the reporting deadline, and hold the arrangement to it
The decision's rarely permanent either way. Plenty of businesses outsource until the finance workload justifies a genuine full time role, then hire into a function that already has clean processes, which makes that eventual hire cheaper and safer than it would otherwise have been.

Quick answers
For most small and mid sized businesses, yes, once you count the full employment cost of super, leave, insurance, software, training and management time against a fixed monthly fee. That comparison narrows though as your finance workload gets closer to a genuine full time role.
