Your accounting function delivered by a firm instead of built as a department: the whole operation, close, reporting, controls, and audit-readiness, run to public-company standards and scaled to your stage.
We deliver your whole accounting function, senior-led and audit-ready, so you scale on the operation instead of building the department.
Outsourced accounting: build versus buy, the whole function, senior review, and scaling to audit-readiness
Key takeaways
What it is. Your accounting function delivered by a firm instead of built as a department: the close, the reporting package, controls, and audit-readiness, with senior review over staff execution, scaled from a first controller need to public-company readiness.
Where it breaks. Building a department is a multi-role hiring cycle with a single point of failure in each role; buying it from a low-oversight provider means work delivered without a senior review layer.
How we help. We run the whole function, close, reconciliations, GAAP financials, AP, payroll, and audit-ready schedules, with a CPA review layer and a clean handoff to your auditors and tax preparer.
Growth companies outgrow bookkeeping long before they can justify a finance department, and the gap between the two is where accounting quietly breaks: a close that slips, reporting that lags the decisions it should inform, and an audit that has to reconstruct the year from incomplete records. Outsourced accounting fills that gap with the function itself, delivered by a firm with the bench a single hire cannot match.
This page covers the outsourced model as a whole: the decision, the scope, the economics, and the scaling path. The senior role at the top of the function has its own deep treatment at controller services, the transaction layer beneath it at bookkeeping, and the forward-looking layer beside it at FP&A; here is how they combine into one operation you do not have to build.
The decision
Build the department, or buy the function
The first decision is whether to build a finance department or buy the function as a service. The same three shapes that describe senior finance leadership apply to the whole operation: an ongoing fraction of a team, temporary coverage of a gap, or the full function delivered by a firm. Building means a multi-role hiring cycle, a salary and overhead per role, and a single point of failure in each; buying delivers senior review over staff execution, a bench of skills on call, and coverage that does not take vacations or resign. For most companies between outgrowing bookkeeping and needing daily in-house presence, buying the function is faster to stand up and cheaper to run.

What it includes
The whole function: judgment, execution, and processing
Outsourced accounting delivers the whole function, not a single task, and the function is three layers. The judgment layer (a CFO) owns cash, capital, pricing, and the board; the execution layer (a controller) owns the close, the reconciliations that prove every balance, and financial statements that are right; and the processing layer (bookkeeping) handles the transactions the controller reviews. We deliver whichever layers you need, from bookkeeping through the controller and, where it fits, a CFO, as one operation with a senior review layer over the staff work, so the numbers are right rather than merely produced.

The core deliverable
The close that anchors the reporting
Everything the function produces rests on a close that lands on time. We rebuild it as a dated, owned process: cutoffs and accruals, standardized reconciliations for every balance sheet account, a flux review, and the reporting package on a fixed date every month. The realistic trajectory is a six-week close compressed to five to ten business days within two or three cycles, then held there by the calendar. A close run to this standard is also what makes the eventual audit cheap, because the reconciliations and standing schedules are the audit request list, pre-built.

The forward-looking layer
Scaling: the forward-looking layer
As a company scales, the function adds a forward-looking layer: a driver-based operating model that expresses the business as its drivers, feeds the budget and the rolling reforecast, and produces the board and lender package and the cash forecast from one source. Because the outsourced model carries the bench, this layer is added when the company needs it rather than through another hire, and the whole function scales through transactions, acquisitions, and audits without a hiring cycle. The handoff to your eventual in-house team is designed in from the start, with documented logic and working files.

Our Experience
Where we have done this work
Engagement Notes
Functions run, not tasks performed
Outsourced accounting engagements across growth and sponsor-backed companies: senior-led closes compressed to business days, accrual-based financials that boards and lenders relied on, systems stacks designed to the stage rather than inherited, and audit-ready schedules maintained continuously so diligence and audits started from ready.
Engagement Notes
The whole arc, one firm
Companies carried across the scaling path without a vendor transition: books run senior-led through growth, technical accounting folded into the close rather than bolted on, first audits met from continuously maintained support, and the function elevated into IPO readiness and PCAOB work by the same team that had run the month-end close since seed.
The Detail
The gaps, and how we close each one
Issue 01
Build a department or buy the function: the honest comparisonThe Decision
Every growing company reaches the point where the founder-and-bookkeeper setup stops scaling, and the instinct is to hire: a controller, then an accountant beneath, then an AP clerk. That path is slow, expensive, and fragile in ways the org chart hides, and it is not the only option.
The treatment
The build path means recruiting, onboarding, and managing a multi-role team, each hire a search, a salary with benefits and overhead, and a single point of failure: the controller who resigns takes the close with them, the clerk who leaves strands the AP. The buy path delivers the same function as a service, senior review over staff execution, coverage that does not take vacations or give notice, and a bench of skills, technical accounting, systems, audit preparation, on call rather than on payroll. The honest comparison is not fees against one salary but the outsourced retainer against the fully loaded cost of the department the function actually requires, plus the management time to run it and the risk concentrated in each role. For most companies between their first serious complexity and a genuine need for daily in-house presence, roughly the range from outgrowing bookkeeping to approaching public scale, buying the function is faster to stand up, cheaper to run, and more resilient. We help make the call honestly, because the answer is sometimes to build, and saying so is the point.
What we do: We run the honest build-versus-buy comparison against the fully loaded department, and tell you when the answer is to build.

The whole function, not a task: what outsourced accounting includesThe Scope
Outsourced accounting gets mistaken for outsourced bookkeeping with a nicer name, which undersells it badly. The distinction is scope: bookkeeping is a task within the function, and the function is everything required to produce reliable financials and keep them audit-ready, month after month.
The treatment
The full operation we run spans the stack: a disciplined monthly close owned end to end (the mechanics detailed on our controller page), balance sheet reconciliations for every account every month, accrual-based GAAP financials rather than cash-basis approximations, a management reporting package with budget-versus-actual and the metrics you manage against, AP and vendor management with real payment controls, payroll and equity-compensation coordination including cap-table tie-outs, audit-ready support schedules maintained continuously so diligence starts from ready, and the systems layer that keeps it all running. The unifying standard is that a public-company controller would recognize the output: reconciled, reviewed, supportable, and on time. That is the line between a task performed and a function run, and it is why the deliverable is a set of financials your board, lenders, and auditors can actually rely on, not a QuickBooks export.
What we do: We run the whole function, close, reconciliations, GAAP financials, AP, payroll, and audit-ready schedules, beyond the books.
Issue 03
Senior-led: why the review layer mattersThe Standard
Much of the outsourced accounting market operates with thin oversight: work delivered with little senior review, priced low and delivering exactly what that implies. The savings are real until the first audit, fundraise, or complex transaction exposes what unreviewed books actually are.
The treatment
We run the function senior-led: experienced accountants, with Big Four expertise where it matters, own the judgment and the review, with staff executing the volume beneath them, the same pyramid a well-run in-house department uses. The difference shows up exactly where it counts, in the judgment calls that need senior experience: the revenue recognition question, the accrual nobody flagged, the reserve that needs support, the transaction that needs a memo. It also shows up in what does not happen, the errors that never enter the ledger because someone who has seen them before caught the pattern, and the audit findings that never arise because the work was done to the standard the auditor tests. The person running your close can walk down the hall to the people who write technical accounting memos for a living, which is a depth of bench no single controller hire provides. Cheap accounting is expensive twice: once when it is done, and again when it is fixed.
What we do: We staff it senior-led, experienced review over staff execution, so the judgment calls get made and the errors never enter the ledger.
From our engagements: The clients who come to us from a cheaper outsourced provider almost never come because of price. They come because the books did not survive contact with an audit, a lender, or a diligence process, and the savings evaporated in the cleanup. Senior review is not a premium; it is the thing that makes the rest worth having.

Scaling with you: from first controller need to public-company readinessThe Path
The finance function a company needs changes with its stage, and the usual failure is a mismatch in either direction: a Series A company with a bookkeeper it has outgrown, or a small company paying for infrastructure built for a much larger one. The outsourced model’s main strength is that it flexes.
The treatment
The engagement scales through the stages without a re-hire at each one. Early: a clean close, reliable monthly financials, and the reporting a first board or lender expects, sized to a company that needs the function but not a department. Growth: deeper controllership, the reserve and accrual discipline that complexity demands, entity consolidations as the structure grows, and the management reporting a scaling business depends on. Pre-institutional and pre-public: the function elevated to diligence and audit grade, support schedules and position memos maintained continuously, the close hardened to a public-company cadence, and the bridge to readiness where the same firm carries you into IPO readiness and PCAOB audit support rather than handing you off at the hard part. Because one firm holds the whole arc, the scaling is continuous, no vendor transition at each stage, no knowledge lost in a handoff, and the function you have at Series C is the one that grew from the function you had at seed, not a replacement bolted on under deadline.
What we do: We scale the engagement through your stages without a re-hire, and bridge you into readiness rather than handing off at the hard part.

The systems layer: the stack that scales past spreadsheetsSystems
Accounting operations depend on a stack, and the stack is usually assembled by accident: QuickBooks chosen at founding, a bill-pay tool added ad hoc, spreadsheets bridging the gaps, until the whole thing groans under volume it was never designed for. The system is quietly the constraint on how well the function can run.
The treatment
We treat the accounting stack as infrastructure to be designed, not inherited: the right general ledger for the stage (QuickBooks Online genuinely suffices longer than vendors admit, and the move to NetSuite or a mid-market ERP belongs at real thresholds, multi-entity complexity, consolidation needs, transaction volume, approaching audit, not at a salesperson’s suggestion), the surrounding tools (AP automation, expense, payroll, close management) selected to fit the ledger and the team rather than accumulated, and the integrations and automation that remove the manual re-keying where errors breed. The discipline is the same one from our FP&A build sequence: buy the tool when the process and the volume genuinely require it, prove the workflow first, and never let software substitute for a process that does not yet exist. Because we run the function on the stack, we design it to be run, not demoed, and we time the upgrades to the business rather than the sales cycle, which is how the systems layer stops being the constraint and starts being the thing that lets the close get faster instead of slower as you grow.
What we do: We design the accounting stack as infrastructure and time the upgrades to your business, not the vendor's sales cycle.
Issue 06
Nothing between vendors: the technical and audit handoffOne Firm
The most expensive gaps in a scaling company’s finance function are the seams between vendors: the bookkeeper who does not do technical accounting, the technical advisor who does not touch the books, the audit-prep firm brought in cold at year-end. Every seam is where knowledge is lost and errors hide, and they multiply exactly as the stakes rise.
The treatment
The structural benefit of running outsourced accounting through a firm that is also a technical and capital-markets practice is that the seams disappear. The close and the technical accounting are done by the same firm, so the revenue policy, the lease conclusions, and the equity accounting flow into the books rather than arriving as memos someone else has to apply. Audit preparation is not a separate engagement: the support schedules are maintained continuously through the year, so the audit starts from ready, and when the audit is a first PCAOB audit, the same firm carries the uplift and preparation. And when institutional capital or the public markets come into view, the function transitions into readiness and capital markets work without a handoff at all. For a growing company, this is the economics of the model: the function delivered without the gaps between the people who deliver it, which is where scaling finance operations usually breaks.
What we do: We remove the seams: technical accounting, audit prep, and readiness run through one firm, so nothing falls between vendors.
FAQ
Frequently asked questions
How is outsourced accounting different from hiring a bookkeeper?
Scope: bookkeeping records transactions; outsourced accounting runs the whole function, the accrual-based close, reconciliations, reporting, controls, and audit-ready support, with senior review on all of it. It is the difference between a task and a controllership, delivered as a service instead of built as a department.
How is this different from your controller services?
Controller services is the senior role, the person who owns the close and the numbers. Outsourced accounting is the whole operation around that role: the role plus the staff execution, the AP and payroll layers, the systems, and the bookkeeping beneath, delivered as one function. Many engagements combine them; this page is the function, that page is the role at its top.
Who actually owns the judgment on our books?
Senior, experienced accountants own the judgment and the review, with a CPA accountable for what is delivered and staff executing the volume beneath them, the same pyramid a good in-house department uses. What you are buying is that senior review layer and the accountability behind it, the thing that carries books through an audit or a raise.
Can you work with our existing systems, and tell us when to upgrade?
Yes to both. We run the function on your stack, commonly QuickBooks Online or NetSuite, and we recommend upgrades only at real thresholds, multi-entity complexity, volume, approaching audit, not on a vendor's schedule. The systems layer is designed to be run, and the upgrades are timed to your business.
What happens when we approach an audit or a fundraise?
Nothing changes hands, which is the point. Support schedules are maintained continuously, so audits and diligence start from ready, and because the same firm handles your technical accounting, audit preparation, and eventually IPO readiness, the function scales into those without a vendor transition at the hardest moment.
