Here’s an uncomfortable thing for an accounting firm to admit: outsourcing isn’t always the right call. Sometimes an in-house bookkeeper beats us — and we’d rather tell you that now than have you find out the hard way

The Promise

In plain English, here’s how to figure out which one actually fits your business — based on your revenue, your transaction volume, and how complicated your books really are. No sales pitch, just the honest threshold.

How much does an in-house bookkeeper cost vs. outsourcing?

The short answer: a full-time in-house bookkeeper typically runs $45,000–$65,000/year in salary alone, before benefits and payroll taxes add another 20–30% on top. Outsourced accounting through a firm like ours runs $130–$245/week ($6,760–$12,740/year) depending on package tier — and that includes a team, not one person’s bandwidth.

For most businesses under $1M in revenue, outsourcing costs less and covers more ground. Above that, the math starts to shift — and that’s exactly where this gets interesting.

The 3 scenarios where in-house actually wins

• High transaction volume with repetitive, predictable work. If you’re processing hundreds of similar transactions daily — think multi-location retail or high-volume e-commerce — a dedicated in-house person who lives inside your systems all day can move faster than a firm juggling multiple clients.
• You’ve outgrown compliance and need embedded operational judgment. Once you’re past roughly $10M in revenue with complex intercompany activity, you often need someone in the building who can make same-day calls tied to daily operations — not just monthly reporting.
• Your industry has non-standard, judgment-heavy bookkeeping every single day. Certain verticals (project-based construction with dozens of active job costs, for example) benefit from a bookkeeper who’s dedicated solely to your job-costing structure, full time.

The 3 scenarios where outsourcing wins

• You’re under $10M and don’t need daily embedded judgment. Most businesses in the $500K–$10M range get more expertise per dollar from an outsourced team than from one hire.
• You want a team, not a single point of failure. One in-house bookkeeper means one set of vacations, one learning curve, one person who might leave. An outsourced firm means backup, review layers, and continuity.
• You want advisory, not just data entry. A solo in-house bookkeeper handles transactions. A firm brings a CPA-level view — tax planning, KPI review, and a second opinion on decisions before you make them.

What this means for you

If you’re not sure which camp you’re in, start with three numbers: your annual revenue, your monthly transaction count, and how many of your bookkeeping decisions require someone who already knows your industry cold. Run those against the tiers above. Most owners land clearly on one side once they see the actual numbers side by side, not just a gut feeling.

Bottom Line

In-house wins on high, repetitive volume or deep operational embedding above roughly $10M in revenue. Outsourcing wins on cost efficiency, coverage, and built-in advisory for most businesses between $500K and $10M. Neither is universally “better” — the right answer depends on your specific numbers, not on which option sounds more comforting.

FAQ

Q: Is it cheaper to hire an in-house bookkeeper or outsource?

For most businesses under $10M in revenue, outsourcing is cheaper on a fully-loaded basis once you account for salary, benefits, payroll taxes, software, and training for an in-house hire.

Q: At what revenue level does an in-house bookkeeper make more sense?

Generally north of $10M in revenue, or sooner if your business has high daily transaction volume that needs someone embedded in operations full time.

Q: Can I switch from in-house to outsourced later?

Yes — many of our clients made that switch specifically because their in-house hire left and they didn’t want to repeat the hiring cycle. Transition typically takes 30-60 days.
