Outsourced vs In-House Bookkeeping: What Small Businesses Should Choose

If your small business has outgrown doing its own books, the next decision is whether to hire a bookkeeper or hand the work to an outside firm. Both get the books done. They differ in cost, in coverage, and in who is accountable when something is missed.

For most small businesses, outsourced bookkeeping is the better fit. It costs a fraction of a full-time hire, comes with review and continuity built in, and scales with transaction volume rather than headcount. In-house bookkeeping makes sense once the work is daily and operational, such as processing a high volume of bills, managing inventory, or running payroll on site, where someone physically inside the business saves real time.

This post covers what each model costs, where each one fits, and what to check before choosing an outsourced provider.

The two models differ in who owns the work

Both models produce the same output: categorized transactions, reconciled accounts, and monthly financial statements. The difference is in structure.

In-house bookkeeping. You hire an employee, part time or full time, who works inside your business. They know your vendors and customers directly and are available during your working hours. You are responsible for hiring, training, reviewing their work, and covering for them when they are away.

Outsourced bookkeeping. An outside firm or independent bookkeeper handles the work remotely for a monthly fee. They work from your bank feeds, accounting software, and documents. The firm is responsible for staffing, quality review, and continuity.

The choice is less about who records transactions and more about who carries the responsibility for getting the books right every month.

In-house costs more than the salary

The median annual wage for bookkeeping, accounting, and auditing clerks in the US was $49,210 in May 2024, according to the Bureau of Labor Statistics. Experienced bookkeepers and those in high-cost metro areas earn more.

The salary is only part of the cost of an employee.

Payroll taxes. The employer pays its share of Social Security and Medicare (7.65% of wages), plus federal and state unemployment taxes.

Benefits. Health insurance, paid time off, and retirement contributions add a significant amount on top of wages for most full-time roles.

Software and equipment. The bookkeeper needs a license for your accounting software, a computer, and access to any other tools the role touches.

Hiring and training. Recruiting takes time, and a new bookkeeper takes weeks to learn your accounts, vendors, and processes.

Review. An in-house bookkeeper still needs someone to check their work, usually your accountant at year end or a manager who understands the books.

A small business with a few hundred transactions a month rarely generates enough work to justify a full-time salary, and part-time bookkeepers can be harder to hire and keep.

Outsourced bookkeeping is priced by volume

Outsourced providers typically charge a monthly fee based on transaction volume, the number of accounts, and any added services such as accounts payable, payroll support, or catch-up work for months that fell behind.

For a small business, that fee is usually a small fraction of a bookkeeper's annual salary. The cost also scales gradually. A business that grows from 50 to 200 transactions a month moves to a higher pricing tier rather than to a second hire.

The trade-off is that outsourced bookkeepers are not inside your business. They rely on you to share receipts, answer categorization questions, and flag unusual transactions. A business owner who doesn't respond to those questions slows the close regardless of who does the bookkeeping.

Outsourcing fits most small businesses

Outsourced bookkeeping is usually the right choice when most of the following apply.

Transaction volume is low to moderate. A few dozen to a few hundred transactions a month doesn't fill a full-time role, so a salaried hire would spend much of the week underused.

The work is monthly, not daily. If the main need is categorizing transactions, reconciling accounts, and producing monthly statements, the work fits naturally into a monthly close cycle.

Nobody in the business can review the books. An outside firm reviews its own bookkeepers' work. With a single in-house hire, errors often go unnoticed until tax time.

Tax and compliance depend on the books. When your books feed directly into your business tax return and state filings, a provider that works alongside tax experts reduces the handoff problems at year end.

You need continuity. An outside firm continues the work when an individual bookkeeper is unavailable or leaves.

In-house makes sense when the work is daily and operational

An in-house bookkeeper earns their cost when the work needs someone inside the business every day.

High transaction volume. Businesses processing thousands of transactions a month, especially with many vendors and customer invoices, can keep a full-time bookkeeper busy.

On-site processes. Physical receipts, cash handling, inventory counts, and job costing on construction or manufacturing sites are easier with someone on location.

Accounts payable and receivable management. If the role includes chasing customer payments, approving vendor bills, and coordinating with operations every day, it is closer to an operations job than a bookkeeping service.

Accounting decisions that need constant internal context. Some businesses need someone who sits in operational meetings and records transactions as decisions are made.

Even in these cases, many businesses keep an outside accountant to review the in-house bookkeeper's work and handle tax filings.

A single in-house hire is a continuity risk

The least-discussed risk of in-house bookkeeping is that it often depends on one person. When that bookkeeper takes leave, falls behind, or resigns, the books stop until someone else learns the accounts.

Small businesses often discover this at the worst moment: during a loan application, a tax deadline, or due diligence, when the books are three months behind and the person who understood them is gone. Catch-up bookkeeping after a gap usually costs more than keeping the books current would have.

An outsourced provider carries this risk on its side. The work is documented in the provider's systems, and another bookkeeper can step in if needed.

Many businesses use a hybrid

The choice doesn't have to be all or nothing. A common arrangement is an in-house administrator or office manager who collects receipts, enters bills, and handles day-to-day payments, with an outsourced bookkeeper who reconciles accounts, closes the books each month, and prepares statements.

This works well for businesses that need someone on site for operational tasks but don't need a full-time bookkeeping specialist. It also keeps a second set of eyes on the books.

What to check before choosing an outsourced provider

Outsourced bookkeeping providers vary widely. These are the questions that separate them.

Whether you get a dedicated bookkeeper. Some providers assign work to a rotating pool, which means re-explaining your business each month. A dedicated bookkeeper builds context over time.

Whether they work in your existing software. Some providers require you to move to their platform. Others work directly in QuickBooks, Xero, or whatever system you already use, which avoids a migration.

How long the monthly close takes. Ask when statements are delivered after month end. Books that close two months late are of limited use for decisions.

Whether the books connect to tax and compliance. A provider that also handles business tax returns and state filings removes the year-end handoff where errors and delays tend to appear.

Whether they understand your entity type and structure. US LLCs, S-corps, C-corps, and foreign-owned companies each have different reporting requirements, and the bookkeeping needs to support them.

Inkle offers monthly bookkeeping with one dedicated bookkeeper per account, either on Inkle Books or on the software you already use, including QuickBooks, Xero, and Zoho Books. Inkle's bookkeeping starts at $49 a month, and because Inkle also handles business tax and compliance filings, the same team that keeps your books is accountable for the filings that depend on them.

The bottom line

For most small businesses, the question isn't whether a bookkeeper would be useful but whether the workload justifies a salary. Until the work is daily and operational, outsourced bookkeeping delivers reconciled books and monthly statements at a lower cost, with review and continuity that a single hire can't provide. The more important decision is often which outsourced provider to choose, since dedicated support, a fast monthly close, and a direct connection to tax and compliance are what make outsourced books reliable.

Frequently asked questions

How much does an in-house bookkeeper cost?

The median annual wage for bookkeeping, accounting, and auditing clerks in the US was $49,210 in May 2024, according to the Bureau of Labor Statistics. The full cost to the employer is higher once payroll taxes, benefits, software, and training are included.

Is outsourced bookkeeping cheaper than hiring?

For most small businesses, yes. Outsourced bookkeeping is typically priced by monthly transaction volume, which for a small business is a small fraction of a full-time salary. The comparison shifts once transaction volume is high enough to keep a full-time bookkeeper busy.

Can an outsourced bookkeeper work in QuickBooks or Xero?

Many can. Some providers work directly in the software you already use, while others require you to move to their own platform. Ask before signing up, since migrating your books adds time and risk.

When should a small business hire an in-house bookkeeper?

Hiring makes sense when bookkeeping becomes daily operational work, such as high transaction volume, on-site inventory or cash handling, or daily management of payables and receivables. Many businesses at that stage still use an outside accountant for review and tax filings.

Is my data safe with an outsourced bookkeeper?

Reputable providers use read-only bank connections, role-based access to your accounting software, and secure document storage. Ask how access is granted and revoked, and whether the provider can see or move money in your accounts.

Do I still need an accountant if I outsource bookkeeping?

Bookkeeping and tax preparation are separate services. Some outsourced bookkeeping providers also prepare business tax returns, which removes the need for a separate tax preparer. If yours doesn't, you will still need someone to file your returns using the books they produce.
