A disclosure before we start: we run an outsourced accounting firm. Asking us to compare in house vs outsourced accounting is a bit like asking a bakery whether you should make your own bread.
So we're going to try extra hard to be fair. There are businesses where hiring someone in-house is the better call, and we'll say which ones. There are also some costs on the in-house side that don't show up in the job posting, and we'll say those too.
What you actually get with in-house accounting
The big advantage is presence. Your in-house bookkeeper or accountant hears the hallway conversation about the new client, sees the delivery truck arrive, and can walk over to ask the sales manager what that $11,000 credit memo was for. That context is real and it's hard to replicate from outside.
You also get availability. If you want someone at a desk from 9 to 5 who can drop everything when the bank calls, an employee is the clearest way to get that.
The trade-offs:
- One person usually holds all the knowledge. When they take two weeks off in August, the books take two weeks off too.
- Nobody reviews their work unless you hire a second, more senior person to do it.
- You pay for a full week whether the business needs 25 hours of accounting or 50.
- Recruiting, training and turnover land on you.
The review gap is the one owners underestimate. A single in-house bookkeeper can be excellent and still miss things, because nobody catches their own blind spots. That's what a controller is for, and few small businesses hire one. There's a whole article on the cost of a full-time controller vs outsourcing the role if that's the part you're weighing.
What you get with outsourced accounting
Outsourcing trades presence for structure. A good outsourced team has more than one person on your books: someone doing the transaction work, someone reviewing it and closing the month, and someone you can ask the bigger questions. When one person is out, the work keeps going.
The trade-offs:
- They won't overhear the hallway conversation. You (or someone on your team) need to answer questions and send documents.
- Response time is measured in hours, not seconds.
- The quality depends heavily on the firm's process, so choosing well matters.
At ABFI, the answer to the context problem is a Client Accounting Manager who coordinates the work and is the person you talk to. You can read how we work for the month-to-month rhythm.
Outsourced accounting vs in house: the side-by-side
Here's the comparison, row by row:
- Coverage: in-house is one person, unless you hire more. Outsourced is a team, with built-in backup.
- Review: in-house is self-review by default. Outsourced, with a good firm, means a separate reviewer and a monthly close.
- Context: in-house wins. They're in the building.
- Cost structure: in-house is salary, benefits, payroll taxes, software, training and recruiting. Outsourced is a monthly fee scoped to your volume.
- Flexibility: in-house is fixed hours. Outsourced scales up or down with your needs.
- Expertise range: in-house is whatever one person knows. Outsourced lets you draw on controller and CFO-level skills when needed.
Neither column is all wins. That's sort of the point.
A worked example: hire accountant vs outsource
Say you run a 22-person staffing firm with one entity, weekly payroll and about 600 transactions a month. You're deciding whether to hire an accountant or outsource.
Option A is a full-time hire. Say you budget $68,000 in salary for a strong bookkeeper (use your own local number here; this is just for the math). Add employer payroll taxes and benefits, and suppose that brings the true cost to around $85,000. Add software seats and some training, and you're near $88,000 a year. That gets you one person doing the work. Nobody is reviewing it.
Option B is an outsourced team. You'd pay a monthly fee based on your volume and the level of service. ABFI's starting points run from $850 a month for Core Accounting to $2,750 a month for a Fractional Department, and where this firm lands depends on scope (weekly payroll and 600 transactions are real work). Ask any firm whether its fee covers review and a monthly close or just data entry.
The math isn't the whole decision. If this staffing firm also needed someone on site to handle timesheets, onboarding paperwork and walk-in questions, an in-house admin plus an outsourced accounting team might be the best mix.

When in-house is the better call
We promised fairness, so here it is. In-house tends to win when:
- Your accounting volume truly fills a full-time role, and then some.
- A lot of the work is physical: receiving inventory, handling cash, filing paper.
- You already have a controller or CFO on staff who can review the work.
- You need same-minute answers all day, every day.
And outsourcing tends to win when the business needs more than one skill level but can't keep each person busy full-time, when nobody currently reviews the books, or when the owner is tired of being the backup bookkeeper.
There's also the hybrid. Plenty of businesses keep an in-house person for daily tasks (bills, invoicing, receipts) and outsource the review, close and reporting. It's like keeping the house tidy yourself and hiring someone for the deep clean, except the deep clean is reconciliations.
In house vs outsourced accounting: how to decide without overthinking it
Ask three questions:
- How many hours a month does the accounting actually take today?
- Who reviews the work before you make decisions on it?
- If your accounting person left tomorrow, what would break?
If the honest answers are "about 40," "nobody" and "everything," that points toward a structure with review and backup built in, which is what a full accounting department is designed to give you.

Questions owners ask
Is outsourced accounting cheaper than in-house?
Often, for small and mid-sized businesses, because you pay for the hours you need rather than a full-time salary plus benefits. Once your volume fills several full-time roles, in-house can become more cost-effective.
Can I outsource accounting and still have someone in-house?
Yes, and many businesses do. A common split is an in-house admin handling daily tasks and an outsourced team doing reconciliations, the monthly close and reporting.
What do I lose by outsourcing accounting?
Mostly physical presence and instant hallway answers. You'll need a habit of sending documents and answering questions, and a firm with a clear process that tells you what it needs and when.
Not sure which side of the table you're on?
If you've been going back and forth on this, a conversation with real numbers usually settles it faster than another spreadsheet. Request a consultation and we'll look at your volume, your current setup and who's reviewing what, then give you a straight answer, even if that answer is "hire in-house."
