How Much Does Outsourced Bookkeeping Cost for a CPA Firm in 2026?

If you run a CPA or accounting firm, you probably already know the problem. 

Your client list is growing. The bookkeeping work is growing with it. Your team is spending more time on reconciliations, transactions, reports, payroll, and month-end work and suddenly you are thinking: 

Should I hire another bookkeeper, or should I outsource the work?

And then comes the next question: 

How much does outsourced bookkeeping actually cost?

That is a fair question. 

The answer depends on the number of clients you have, the amount of bookkeeping work, the complexity of the accounts, the software you use, and the type of support you need. 

In this guide, we will break down outsourced bookkeeping costs, common pricing models, what affects the price, and when outsourcing can make more sense than hiring an in-house bookkeeper. 

What Is Outsourced Bookkeeping? 

Outsourced bookkeeping means hiring an external bookkeeping team or accounting service provider to handle some or all of your bookkeeping work. 

Instead of hiring another full-time employee, you have an external team working as an extension of your accounting firm. 

Depending on your requirements, outsourced bookkeeping can include: 

• Bank and credit card reconciliation 
• Accounts payable 
• Accounts receivable 
• Invoice processing 
• Expense management 
• Payroll processing 
• General ledger maintenance 
• Month-end closing 
• Financial reporting 
• Cash flow reporting 
• Cleanup and catch-up bookkeeping 
• Xero bookkeeping 
• QuickBooks bookkeeping 
• MYOB bookkeeping 
• BAS preparation support 

The important part is that you don’t necessarily have to outsource everything. 

You can outsource only the tasks that are taking too much time from your internal team. 

How Much Does Outsourced Bookkeeping Cost? 

There isn’t one fixed price for outsourced bookkeeping. 

Most providers use one of three common pricing structures: 

1. Hourly Pricing

You pay for the actual hours worked. 

This can work well if your workload changes from month to month. 

For example, you may need more bookkeeping support during tax season and less support during quieter months. 

Hourly pricing is often useful when you are testing outsourcing for the first time or when you only need help with specific tasks. 

2. Fixed Monthly Pricing

With fixed monthly pricing, you pay an agreed amount every month for a defined scope of work. 

This can make budgeting easier because you know approximately what your bookkeeping cost will be each month. 

It can be a good option for firms with a consistent workload. 

3. Dedicated Bookkeeper or Team

Some CPA firms choose to work with a dedicated offshore bookkeeper or bookkeeping team. 

Instead of paying for individual tasks, you have a professional or team assigned to your firm’s workflow. 

This can make sense when you have a larger client base and a steady amount of bookkeeping work. 

What Actually Determines the Cost? 

This is where things get interesting. 

Two CPA firms can have completely different outsourcing costs even if they both have 50 clients. 

Why? 

Because the number of clients isn’t the only factor. 

Here are some of the biggest factors. 

1. Number of Clients

More clients usually means more transactions, more accounts, more reconciliations, and more reporting. 

A firm with 20 straightforward bookkeeping clients will have very different requirements from a firm with 20 clients that have complicated transactions every week. 

2. Transaction Volume

A small business with 100 transactions per month is very different from a business processing thousands of transactions. 

Higher transaction volume generally requires more bookkeeping time. 

3. Cleanup Work

This is a big one. 

If your client’s books haven’t been maintained properly for six months—or even several years you may need cleanup and catch-up bookkeeping before normal monthly bookkeeping can begin. 

That initial cleanup can require significantly more work than ongoing bookkeeping. 

4. Services You Need

Basic bookkeeping is one thing. 

But if you also need: 

• Payroll 
• Accounts payable 
• Accounts receivable 
• Financial reporting 
• Cash flow reporting 
• Month-end closing 
• Budgeting support 
• BAS support 

the overall cost can increase. 

5. Accounting Software

The software your clients use can also affect the workflow. 

Many firms work with platforms such as: 

• Xero 
• QuickBooks 
• MYOB 
• Sage 
• Zoho Books 
• Reckon 

A bookkeeping partner familiar with your software can make onboarding much easier. 

Outsourced Bookkeeping vs Hiring an In-House Bookkeeper 

This is probably the question most CPA firm owners actually want answered. 

Would outsourcing really be cheaper than hiring someone?

Sometimes, yes. 

But cost isn’t the only thing you should consider. 

Hiring an in-house employee can mean dealing with: 

• Salary 
• Benefits 
• Recruitment 
• Training 
• Payroll taxes 
• Paid leave 
• Equipment 
• Software 
• Office costs 
• Employee turnover 

And there is another problem: 

What happens when your workload suddenly increases? 

You may need another person during your busiest months but not necessarily for the entire year. 

Outsourcing gives you the option to scale support based on your workload. 
For example, your firm might start with one outsourced bookkeeper and later increase the team as your client base grows. 

That flexibility can be particularly useful for growing accounting firms. 

When Does Outsourcing Make Sense for a CPA Firm? 

Outsourcing isn’t automatically the right answer for every firm. 

But you should seriously consider it if you recognize some of these situations. 

Your team is constantly overloaded 

If your bookkeepers are spending their days trying to catch up with basic bookkeeping tasks, something needs to change. 

Your partners are doing bookkeeping 

This is a bigger problem than it looks. 

If the firm’s owner or senior accountant is spending hours fixing transactions instead of working on higher-value services, the firm’s growth can suffer. 

You are turning away clients 

If you have more potential clients than your team can handle, outsourcing can give you additional capacity without immediately hiring another full-time employee. 

Tax season becomes chaotic 

Many accounting firms experience a huge increase in workload during busy periods. 
Having additional bookkeeping support can help your internal team stay focused. 

You want to grow without constantly hiring 

This is one of the biggest reasons accounting firms consider outsourcing. 

Instead of building a large internal team immediately, you can add external bookkeeping capacity as your business grows. 

Can You Outsource Only Certain Bookkeeping Tasks? 

Absolutely. 

You don’t have to hand over your entire bookkeeping department. 

For example, your internal team could continue handling client communication and review while your outsourced team handles: 

Bank reconciliations → Transaction categorization → Accounts payable → Accounts receivable → Payroll → Monthly reports 

Your CPA or senior accountant can then review the work before it reaches the client. 

This type of hybrid model can be a great starting point for firms that aren’t ready to outsource everything. 

What Should You Ask Before Hiring an Outsourced Bookkeeping Partner? 

Don’t choose a provider simply because they offer the lowest hourly rate. 

Ask these questions first: 

1. What accounting software do you support?

Make sure the provider already understands the platforms your clients use. 

2. Who will actually do the work?

Ask about qualifications, experience, training, and whether you will have a dedicated team. 

3. How do you handle data security?

Your clients trust you with sensitive financial information, so security should be taken seriously. 

4. How will communication work?

Find out how you’ll communicate, how often you’ll receive updates, and who your main point of contact will be. 

5. Can the team scale with us?

Your needs today may not be the same six months from now. 

Choose a partner that can increase or decrease support when necessary. 

6. What happens duringbusyseason? 

This is especially important for CPA firms. 

You don’t want your outsourcing partner to disappear when your workload increases. 

Is Outsourced Bookkeeping Worth It in 2026? 

For many growing CPA and accounting firms, the bigger question isn’t: 

Can we afford outsourced bookkeeping?

It’s: 

How much is our current workload costing us? 

If your senior employees are spending hours every week on repetitive bookkeeping tasks, you’re paying for that time. 

If you’re turning away new clients because your team is already overloaded, you’re losing potential revenue. 

And if your partners are stuck doing work that could be delegated, you’re losing valuable time that could be spent on advisory services, client relationships, and business development. 

That’s where outsourcing can become more than a cost-saving strategy. 

It can become a growth strategy. 

The right outsourcing model can give your firm access to additional bookkeeping capacity without forcing you to immediately build a larger internal team.

It can be, depending on your workload and requirements. Outsourcing can reduce the need for recruitment, training, employee benefits, equipment, and other overhead costs. 

Can a small CPA firm outsource bookkeeping? 

Yes. Small firms can outsource specific tasks or use a dedicated bookkeeping resource rather than building a large internal team. 

Can I outsource only bank reconciliation? 

Yes. You can outsource individual bookkeeping tasks instead of your entire bookkeeping operation.

Many providers support popular platforms such as Xero, QuickBooks, MYOB, Sage, and Zoho Books. Accounting Farm currently lists Xero, MYOB, QuickBooks, Sage, and other platforms among its technology expertise. 

How do I choose the right bookkeeping outsourcing company? 

Look beyond price. Consider experience, software expertise, communication, security, scalability, turnaround time, and whether the provider understands the needs of CPA and accounting firms. 

Final Thought 

Outsourcing bookkeeping isn’t about replacing your entire accounting team. 

It’s about giving your team more time to do the work that actually requires their expertise. 

If your firm is growing but your bookkeeping workload is growing even faster, outsourcing could be the extra capacity you need. 

The goal isn’t simply to reduce bookkeeping costs. 

The goal is to build a CPA firm that can grow without constantly adding more pressure to your internal team.
