What Is Finance as a Service (FaaS)?
Finance as a service (FaaS) is a subscription model that bundles a company’s entire finance function into one monthly engagement. Instead of hiring a bookkeeper, then a controller, then a tax preparer, then a CFO separately, you pay one recurring fee to an outside team that owns bookkeeping, GAAP accounting and the monthly close, tax preparation and filing, and fractional CFO advisory together.
The naming can confuse. Ask what is finance as a service, and you’ll get two answers. In fintech, the phrase sometimes means embedded banking, payments, and lending delivered through APIs. In accounting, and throughout this guide, it means the outsourced, subscription-based delivery of your finance function.
FaaS also isn’t the same as a few adjacent terms. Finance and accounting outsourcing (FAO) and business process outsourcing (BPO) usually describe enterprise-scale, task-by-task offshoring. A standalone fractional CFO gives you strategy without the bookkeeping and close underneath it. FaaS is the middle path: the full stack, transactional through strategic, sized for a growing company and priced as one subscription.
A few distinctions make FaaS easy to spot:
- It’s a bundle, not a task. FaaS packages the transactional layer (bookkeeping) and the strategic layer (controller and CFO work) under one contract.
- It’s a subscription, not a placement. You pay a predictable monthly fee, not hourly project billing or per-hire staffing costs.
- It’s a managed result, not a resume. You get accurate books, an on-time close, filed returns, and forward-looking guidance from a team you don’t have to onboard or supervise.
FaaS is aimed at companies that have outgrown a solo bookkeeper but aren’t ready to staff a full finance department, usually in the $1M to $20M revenue range. Outsourcing the finance function is mainstream now, not fringe. In Deloitte’s 2024 Global Outsourcing Survey, finance ranked among the most widely outsourced functions, and 83% of surveyed organizations named cost reduction as a primary motive. The talent squeeze is part of the reason. Deloitte found that only about 1 in 10 CFOs report no finance talent shortage, which pushes companies toward buying the whole function rather than competing to hire each role.
What Finance as a Service Includes
A complete finance as a service engagement covers four layers most companies otherwise buy or hire one piece at a time. The value is that a single team runs all four off the same set of books.
- Bookkeeping, the transactional layer. Categorizing transactions, reconciling bank and credit-card accounts, and keeping accounts payable, accounts receivable, and the general ledger current. The Bureau of Labor Statistics puts the median wage for bookkeeping and accounting clerks at $49,210 as of May 2024.
- Accounting and the monthly GAAP close, the accuracy layer. Turning clean books into financial statements that follow Generally Accepted Accounting Principles, the reporting standards maintained by the Financial Accounting Standards Board. GAAP runs on the accrual basis, so revenue and expenses land when they’re earned or incurred, not when cash moves. This is the layer that makes financials audit-ready, and the one a la carte bookkeeping most often skips. Accountants and auditors earned a median $81,680 in the same period.
- Tax preparation and compliance, the filing layer. Federal, state, and, where it applies, multi-state and multi-entity returns, plus year-round planning. In a FaaS bundle the return is built from the same ledger the accounting team maintains, not reconstructed by an outside preparer every December.
- Fractional CFO advisory, the strategy layer. Part-time senior finance leadership without a full-time executive salary: cash-flow forecasting, budgeting and modeling, fundraising and board reporting, and unit-economics analysis. A full-time CFO is expensive. The Robert Half 2026 Salary Guide projects CFO base pay from $195,500 to $321,750 before bonus and benefits.
Good FaaS accounting also runs on a shared cloud stack, QuickBooks Online or NetSuite plus reporting dashboards, and a serious provider holds a SOC 2 report, the independent attestation that its controls protect your financial data. This is where the bundle earns its keep. Indinero runs all four layers as one engagement, so your close, your tax return, and your forecast all come from the same numbers.
FaaS vs Traditional Outsourced Accounting
The finance as a service vs outsourced accounting question comes down to scope and accountability. Traditional outsourced accounting usually sells one task or one person you still manage. FaaS sells the whole finance function as one accountable subscription. In practice, buyers weigh four models: FaaS, a la carte bookkeeping, a staffing or temp agency placement, and building an in-house team.
| Criteria | Finance as a service | A la carte bookkeeping | Staffing / temp agency | In-house team |
|---|---|---|---|---|
| What you get | The full function: bookkeeping, GAAP close, tax, CFO advisory | One task, usually bookkeeping | A contractor you direct | Employees you recruit and retain |
| Who owns the outcome | The provider | You stitch tasks together | You supervise the worker | You build and run the team |
| GAAP close and accrual reporting | Included | Rarely, often cash-basis | Depends on the individual | Yes, if you hire senior enough |
| CFO-level advisory | Included via fractional CFO | No | Only if you place a senior contractor | Yes, if you can afford a CFO |
| Management burden | Low, one team | Medium, you coordinate | High, you onboard and direct | Highest, you hire and cover turnover |
| Cost model | Fixed monthly subscription | Per task or hourly | Placement fee plus wages | Salaries plus benefits and overhead |
| Time to stand up | Weeks | Fast for one task, slow for a full function | Weeks to fill a role | Months to hire and ramp |
The alternatives each solve a slice. A la carte bookkeeping keeps your ledger current and reconciled, but it rarely delivers a GAAP close, a tax strategy, or a forecast. You end up coordinating the missing pieces yourself.
A staffing agency fills a seat fast, but you still scope the work, review the output, and absorb the turnover when the contractor leaves. An in-house team gives you the most control and often the best long-run cost, once you’re large enough to keep a bookkeeper, an accountant, and a CFO all busy. FaaS trades some of that control for full coverage at a fixed monthly price.
The math is what drives most decisions. Rebuilt in-house, the same coverage means stacking a bookkeeper near a $49,210 median, an accountant around $81,680, and a CFO from $195,500 to $321,750, before benefits, software, and overhead. That runs well into the mid-six figures in salary alone.
The bundle is the point.
Put simply, a la carte fits a company that only needs clean books, an in-house team fits one large enough to keep a CFO busy, and FaaS fits the stretch in between, where you need the whole function but not a full department.

How to Choose a FaaS Provider
The best finance as a service providers cover the full stack under one roof, keep books on a GAAP accrual basis, staff the work with credentialed accountants, and protect your data with a SOC 2 report. Use this as a buyer’s checklist.
- Full-stack coverage under one contract. Confirm the provider actually delivers all four layers, bookkeeping, GAAP close, tax, and CFO advisory, rather than bookkeeping with everything else referred out. The bundle is the entire reason to buy FaaS.
- CPA-led, not bookkeeper-only. Ask who reviews the work and what they’re credentialed to sign off on. Automation is fine, but judgment calls belong to a human accountant.
- A real GAAP close. Ask whether they close on the accrual basis and produce GAAP financial statements, the standard lenders, auditors, and investors expect. Good FaaS accounting is audit-ready before anyone asks.
- Tax integrated with accounting. The strongest setups file your return off the same ledger the accounting team keeps, so planning happens year-round and nothing is rebuilt at year-end.
- Fractional CFO depth. Confirm the advisory layer includes forecasting, budgeting, fundraising support, and board reporting, not just a monthly email with the financials attached. If you’re unsure what that scope should cover, our guide to fractional CFO advisory breaks it down.
- SOC 2 and data security. A SOC 2 report is an independent CPA attestation of a provider’s controls over your financial data. Ask to see it.
- Transparent pricing and flexible terms. Look for a published starting price and month-to-month options instead of opaque custom quotes and long lock-ins.
- A track record that scales with you. Tenure, verified reviews, and the ability to handle multi-state and multi-entity complexity signal a provider that can carry you to your next stage, not just today’s.
One practical test: ask a prospective provider to walk through a recent monthly close and how it feeds the tax return and the forecast. A real finance as a service provider can trace that path end to end. A repackaged bookkeeping service usually can’t.
How Indinero Delivers Finance as a Service
Indinero is a finance as a service provider that bundles bookkeeping, GAAP accounting and the monthly close, tax, and fractional CFO advisory into a single monthly engagement. Growth-stage and mid-market companies get one accountable team instead of four separate vendors and hires.
What that looks like in practice:
- A GAAP-first, CPA-led team. Your books are kept on the accrual basis and reviewed by credentialed accountants, not produced by software alone. Audit-ready, not audit-painful.
- Continuous operations since 2009. Finance is a function no business can afford to have go dark mid-year, and indinero has run without interruption for that entire stretch.
- Scale and depth. 500+ regular customers rely on indinero for their finance function, backed by 100+ years combined team experience across accounting and tax.
- Security you can verify. indinero is SOC 2 compliant (2026), so the controls over your financial data are independently attested, not just asserted.
- Transparent, flexible terms. Pricing starts at $750/mo, and month-to-month engagements are available, so you’re not locked into a long contract to get started. The 5-star Clutch rating comes from verified client reviews.
Because the same team handles your tax, there’s no handoff at year-end. Your credits, your entity elections, and your estimated payments are decided by the people who already keep your books. The point of finance as a service isn’t cheaper bookkeeping. It’s one team carrying your books, your close, your taxes, and your forecast forward together, so your finances stay ahead of the next decision instead of catching up to the last one.

Frequently asked questions
Below are the questions growth-stage buyers ask most before choosing a finance as a service partner.
What does finance as a service include?
Finance as a service includes four layers under one monthly engagement: bookkeeping, GAAP accounting and the monthly close, tax filing, and fractional CFO advisory. The value is that a single team runs all four off the same set of books, so your close, your return, and your forecast all trace to the same numbers. At indinero, that bundle runs as one engagement rather than four separate vendors and hires.
How is FaaS different from outsourced bookkeeping?
FaaS differs from outsourced bookkeeping by owning the whole finance function, not just a clean ledger. Standalone bookkeeping keeps your accounts reconciled, but it usually stops short of accrual reporting, tax planning, and fractional CFO guidance, leaving you to coordinate the missing pieces. Indinero runs all four layers as one monthly engagement, so nothing gets rebuilt at year-end.
How much does finance as a service cost?
Finance as a service pricing at indinero starts at $750/mo, with month-to-month engagements available so you’re not locked into a long contract to begin. The subscription replaces four separate salaries, since rebuilding the same coverage in-house means stacking a bookkeeper, an accountant, and a CFO, which runs well into the mid-six figures before benefits and overhead. Final pricing depends on your revenue, entity count, and how much CFO depth you need.
Is finance as a service the same as a fractional CFO?
Finance as a service isn’t the same as a fractional CFO, though it includes one. A standalone fractional CFO gives you strategy, forecasting, and board-ready reporting, but without the bookkeeping and monthly close underneath it. At indinero, the fractional CFO layer sits on top of bookkeeping, accounting, and tax, so your forecast draws from the same books their team maintains.
Who is finance as a service best for?
Finance as a service fits companies that have outgrown a solo bookkeeper but aren’t ready to staff a full finance department. That’s typically growth-stage and mid-market operators in the $1M to $20M revenue range, founders who need audit-ready books for a raise, and finance leads scaling without three new hires. Indinero has run this model for 500+ regular customers since 2009, backed by 100+ years of combined team experience.
