Whether to hire an accounting person or engage a firm, compared on true cost, breadth of expertise, and what happens when the person handling your books is away.
Outsource while the work is under roughly one full-time role: a firm costs less than a salaried hire once benefits, payroll taxes, software and management time are counted, and covers bookkeeping through to tax in one engagement. Hire in-house once transaction volume needs daily attention or the work requires constant business context.
The usual comparison puts a bookkeeper's salary next to a firm's annual fee, and the salary looks competitive. It is not the same number. An employee costs salary plus the employer's share of payroll taxes, paid time off, benefits, software licences, training, equipment, recruitment, and your own time managing them. A firm's fee covers all of it, including the CPA review the in-house role would still need at year-end.
A single in-house bookkeeper is a single point of failure. When they are on vacation, remittances still have deadlines. When they resign, the knowledge leaves with them, and it usually leaves mid-cycle. Businesses discover this at the worst possible time — during a sales-tax audit, a financing round, or a year-end when nobody can explain the prior year's entries. A firm carries the same knowledge across a team.
An in-house person handles day-to-day recording, invoicing and payments, and a CPA firm handles month-end review, sales tax, payroll compliance and year-end filings. That gets the responsiveness of an employee and the expertise range and review of a firm, and it fixes the segregation-of-duties problem — the person recording transactions is not the person reviewing them.
| In-house hire | Outsourced firm | |
|---|---|---|
| True cost | Salary plus payroll taxes, benefits, software licences, training and your management time | A fee, with no employment overhead |
| Range of expertise | One person’s skill set | Bookkeeper, tax specialist and CPA on the same engagement |
| Coverage | Stops during vacation, illness and after a resignation | Continuous; the firm absorbs absences |
| Business context | Deep — they sit inside the business every day | Requires deliberate communication to build |
| Responsiveness | Immediate | Within agreed turnaround |
| Scaling | Another hire, another search | Adjust the engagement |
| Segregation of duties | Hard with one person; a real fraud risk | Built in — different people record and review |
High daily transaction volume, businesses needing physical presence, and companies large enough to staff more than one accounting role.
Businesses under roughly one full-time role of work, seasonal businesses, and anyone who needs bookkeeping through to tax without managing staff.
