Not sure how to outsource? Take this quick quiz and get a roadmap built around your specific situation.
You’ve probably already Googled “outsourced accounting services” and come back with a lot of vague advice and very few actual numbers.
Most articles tell you that outsourcing saves money and scales with your business. Few tell you what it costs, which model fits your situation, or what a clean handoff actually looks like in practice.
This guide on how to outsource accounting services explains exactly that.
You’ll get specific cost ranges by service tier, a straight comparison of offshore versus domestic versus hybrid models, and a step-by-step process from scoping your workload to closing your first month with a new provider.
TL;DR – How to Outsource Accounting Services
Not ready to read the full guide? Here is the short version.
- Start by listing every accounting task that is eating your time or falling behind. That becomes your outsourcing scope.
- Decide how much hands-on involvement you want. Offshore teams cost less; domestic firms cost more but come with fewer time-zone and communication gaps.
- Vet any provider you are considering. Ask for their credentials, check their security certifications, and request references from clients in your industry.
- Get the agreement very clear before you sign anything. Know exactly what you are getting, by when, and what might cost you extra money.
- Do a secure data handoff. Set up role-based access, require multi-factor authentication, and sign an NDA before sharing any financial information.
- Give it 60 to 90 days. Most engagements reach steady state by the end of the third month, and that is usually when you start seeing the real value.
What Outsourced Accounting Means for Your Business?
Outsourced accounting means paying an external firm to handle your accounting rather than managing it with internal staff. The firm assigns accountants, controllers, or advisors to your account, works inside your existing software, and delivers reports on an agreed schedule.
This differs from when you hire a freelancer. You might find that a solo contractor is cheaper upfront. But they create a single point of failure with no backup. Anything might go wrong at any time.
A full-service outsourced accounting firm gives you a team, structured processes, and clear accountability.
Reasons to Outsource Your Accounting Function
The US has roughly 340,000 fewer accountants than it did 5 years ago, a 17% drop according to Bloomberg’s analysis. That shortage pushes up salaries. It also extends hiring timelines.
A senior accountant runs $80,000 to $122,000 all-in; a CFO can reach $283,000. Outsourcing gives you access to those skill levels at a fraction of the cost.
Beyond the talent gap, the main reasons to outsource your accounting function are:
- Lower, predictable costs: The cost advantages of outsourcing accounting are real. A $2,000-per-month outsourced bookkeeper runs about $24,000 per year. A comparable full-time hire costs $55,000 to $75,000, when you include benefits and overhead.
- Access to a full team: One hire gets you one skill set. An outsourced firm gives you bookkeepers, tax specialists, controllers, and a CFO under one arrangement.
- Scalability: Transaction volume in Q4 is nothing like Q1. An outsourced team adjusts without any hiring or firing.
- Stronger internal controls: Separation of duties is built into the model, which reduces fraud exposure.
When Outsourcing Is the Wrong Call?
If your books are genuinely simple and you can manage them in a few hours a month, the cost may not be justified yet.
Similarly, if your data has strict regulatory requirements around external access, take extra care in provider selection or keep the work in-house until you find a firm that meets your compliance needs.
Types of Outsourced Accounting Services
Outsourcing is modular. You can start with one layer and add more as your needs grow.
| Service Tier | What It Includes | Best Fit |
| Bookkeeping | Transaction coding, reconciliations, basic monthly reports | Startups, small businesses |
| AP/AR and payroll | Vendor payments, invoicing, and payroll processing | Small to mid-size businesses |
| Financial reporting and close | GAAP statements, variance analysis, and management reporting | Growing mid-market companies |
| Controller-level | Internal controls, audit prep, and close oversight | Companies needing CFO-ready financials |
| Fractional CFO | Forecasting, board reporting, capital planning | Companies raising capital or scaling fast |
CDH’s outsourced accounting and bookkeeping services cover transaction processing through financial reporting.
For companies outsourcing broader back-office operations, CDH’s business process outsourcing services bundle accounting with other finance functions.
For AP/AR and payroll, to outsource payroll specifically:
- Provide employee data, tax IDs, and pay history.
- Run parallel payrolls for 1 or 2 cycles to verify accuracy.
- You can then fully hand off.
Keep in mind that even when a provider processes payroll, you remain legally liable for any filing errors.
Controller and fractional CFO work adds forecasting, board presentations, and strategic finance guidance. A common mistake is putting a CFO on a team that still has unreconciled books.
CDH’s fractional CFO and controller support is structured so that each level handles the work it is meant for.

How to Outsource Your Accounting in 6 Steps
Follow these steps to go from “we should probably outsource this” to a live, running engagement.
Step 1: Define Your Scope and Goals.
Before contacting any provider, answer these questions:
- Where are things falling behind right now?
- What would “fixed” actually look like six months from now?
- Where do you draw the line on handing things off?
- What software are you already running?
Step 2: Decide Between Offshore, Domestic, and Hybrid Models.
Each model comes with real trade-offs on cost, communication, and control. Here is how they compare.
| Factor | Offshore (India, Philippines) | Domestic (US-based) | Hybrid |
| Cost | $8 to $25/hr; 40 to 70% savings | $75 to $400/hr CPA rates | Mid-range |
| Communication | 8 to 12-hour time-zone gap | Same time zone | Overlap hours vary |
| Security oversight | Extra due diligence required | The US legal framework applies | Split responsibility |
| Best fit | High volume, clear processes | Complex tax, sensitive data | Transaction work offshore, advisory onshore |
Step 3: Vet Potential Outsourcing Partners.
Use these questions on a discovery call:
- Who handles my account day to day, and what are their credentials?
- Do you have experience with my industry and revenue level?
- What software do you use? Can you work in my existing system?
- What are your security certifications? SOC 2 Type 2 or ISO 27001?
- What does onboarding look like, and how long until steady state?
- What is your response time for routine questions versus urgent issues?
- How is pricing structured, and what triggers an out-of-scope charge?
You need to watch out for firms that assign senior staff during the sales process, then replace them with juniors after signing.
Don’t forget to ask explicitly who your dedicated contact will be post-onboarding.
Step 4: Compare Pricing and Service Level Agreements.
Monthly retainers now represent the vast majority of pricing arrangements.
A solid SLA should specify:
- Deliverables and deadlines
- Response time commitments
- How scope changes are priced
- What happens when deadlines are missed
- Exit terms including data return
Mentioning these precisely in a written agreement helps make the partnership smoother. Also, you can hold the firm accountable in case anything goes wrong.
Step 5: Plan a Secure Data and Software Handoff.
Before sharing any financial data, get these safeguards in place. Skipping even one of them is how breaches happen.
- Execute NDAs and data processing agreements that spell out how your data is used, stored, and deleted.
- Set role-based access so the provider sees only what they need to do their work.
- Require multi-factor authentication for all system logins.
- Confirm where your data is stored and under which jurisdiction.
- Run a quick audit of who currently has access to your systems and revoke anything that is no longer needed.
- Ask the provider directly how they handle a breach, and get their incident response process in writing.
- Keep a local backup of your financial records so you are never fully dependent on the provider’s systems.
Per IBM’s 2025 Cost of a Data Breach Report, financial-sector breaches average $5.56 million in damages, the second-highest of any industry. Choose a provider that takes security as seriously as you do.
Step 6: Set Reporting and Review Cadences.
You want to know what is happening with your books without having to chase anyone. This is how you make that happen (by setting checkpoints).
- Weekly: Check-ins on AP/AR exceptions and open items.
- Monthly: Close review call covering financial statements and variances.
- Quarterly: Business review covering forecasts and process improvements.
Designate one person internally to own the relationship. Outsourcing without internal oversight is one of the most common reasons these arrangements break down.
What Outsourced Accounting Services Cost
Costs vary based on what you hand off. Here is what you can expect to pay each month in the US, broken down by service tier.
| Service Tier | Monthly Range (US) | What Is Included |
| Bookkeeping only | $500 to $2,500 | Transaction coding, reconciliations, basic monthly reports |
| Full-service accounting | $1,500 to $5,000 | Bookkeeping, AP/AR, payroll, monthly close, GAAP statements |
| Controller-level | $3,500 to $7,500 | Full-service plus controls, audit prep, and reporting design |
| Outsourced CFO | $5,000 to $12,000+ | Forecasting, board reporting, capital planning |
Watch for costs outside the base quote, such as onboarding fees, historical cleanup, year-end tax work, and additional reporting, which can all add to your bill if they are not specified upfront.
Mistakes to Avoid When You Outsource Accounting
A few recurring mistakes account for the majority of failed outsourcing relationships. Here are those mistakes:
- Choosing on price alone: Fixing accounting errors can cost 5 to 10 times more than preventing them. A $400-per-month provider who misclassifies transactions is more expensive than a $1,500 firm that closes cleanly every month.
- No internal owner: Someone at your company still needs to review reports, approve payments, and escalate exceptions. The oversight should always stay with you.
- Vague scope and SLAs: Without specific deliverables and deadlines in the contract, you have no basis for holding the firm accountable.
- Skipping the security review: Request the SOC 2 Type 2 report or ISO 27001 certificate. A reputable firm produces it without hesitation.
How to Choose the Right Outsourced Accounting Partner
A few things separate a strong partner from a low-cost vendor.
- Industry experience: Find a firm that has worked with businesses like yours. They will already understand your reporting needs and where things typically go wrong in your sector.
- Technology alignment: If you run QuickBooks and your provider only works in Xero, you are the one doing manual exports. Make sure they can work in your existing system before you commit.
- Sage Intacct experience: If your business is scaling fast or managing multiple entities, ask whether your provider works in Sage Intacct. It is the only accounting software formally recommended by the AICPA, and not every firm knows it well.
- Team structure: Know exactly who is on your account, what their credentials are, and whether that same team stays with you after onboarding. Turnover mid-engagement is more common than you think.
- CPA-led versus bookkeeping-only: If you need GAAP-compliant financials, audit support, or tax guidance, you want a licensed CPA firm only.
- Exit terms: Before you sign, ask what happens to your data when the engagement ends. You should get your files back promptly and without any conditions attached.
What to Expect After You Hand Off Your Books
The first few months set the tone for the entire engagement. Here is what a well-run transition typically looks like.
- Days 1 to 30: The firm reviews your chart of accounts, reconciles any open items, and sets up secure access to your systems. You will go back and forth a bit as they get familiar with your vendors, customers, and how you code transactions. That is normal.
- Days 31 to 60: Your first full close under the new arrangement. A good firm walks you through the financials on a call and flags anything that looks off. A clean, on-time close at this stage is a good sign.
- Days 61 to 90: By month three, things should feel routine. Your reports arrive on schedule, issues get flagged before you have to ask, and the team is thinking ahead instead of waiting on you. That is when you know it is working.
Frequently Asked Questions(FAQs)
These quick answers cover the questions that come up most often during the evaluation process.
Is It Safe to Outsource Accounting Services?
Yes, with proper vetting. Ask any provider for their SOC 2 Type 2 report or ISO 27001 certification, which confirms independently tested security controls.
Require signed NDAs, role-based access, and multi-factor authentication before sharing any financial data. A reputable firm will have all of this ready before you ask.
How Long Does the Transition From In-House to Outsourced Accounting Take?
For most mid-market companies, 4 to 12 weeks covers the full transition from signed agreement to steady-state reporting. Simple engagements with clean books move faster. Multi-entity structures or years of unreconciled data extend the timeline.
Can You Outsource Only Part of Your Accounting Function?
Yes. Payroll, AP, AR, and month-end close can each be handed off independently. Companies with a strong in-house controller often outsource only the transactional layer while keeping reporting and strategy internal.
What Is the Difference Between Outsourced Accounting and a Fractional CFO?
Outsourced accounting covers execution: recording transactions, closing the books, and preparing financial statements.
A fractional CFO is a strategic role focused on forecasting, capital planning, and finance leadership.
The CFO’s role depends on clean accounting data to function. Many firms offer both as a bundled engagement.
Are Outsourced Bookkeeping and Outsourced Accounting the Same Thing?
No. Bookkeeping is a subset of accounting. Outsourced bookkeeping records and organizes transactions. Full outsourcing accounting and bookkeeping services go further, interpreting data, ensuring GAAP compliance, and delivering management-level reporting.
If you need more than a monthly P&L, full outsourced accounting is the right scope.
