Bookkeeper — records the data
Categorizes transactions, reconciles accounts, captures receipts, produces the raw monthly numbers. The operational foundation. Answers: is it recorded? Delivered through monthly bookkeeping.
Accounting services
Outsourced controller services
Someone has to own whether the books are right.
A bookkeeper records the transactions. A CFO sets the strategy. Between them sits the role most growth-stage businesses skip — the controller, who owns the close, the accuracy of the statements, and the controls that keep it all accurate. TechBrot delivers that oversight with a signed controller-level specialist practice, on a fixed retainer of $1,800–$5,000 a month on top of monthly bookkeeping — the rung between monthly bookkeeping and a fractional CFO, without a full-time controller’s salary. Actual scope and retainer vary with close complexity, number of entities, reporting cadence, and the controls you need.

§ 01 · TL;DR
§ TL;DR
A controller owns whether the books are right: the month-end close, financial statement review, internal controls, bookkeeping supervision and the reporting calendar. TechBrot delivers outsourced controller services with a signed controller-level specialist practice on a fixed retainer of $1,800–$5,000/mo on top of monthly bookkeeping. Tax filing, audit and IRS representation stay with your CPA.
They took something that felt overwhelming to me as a first-year business owner and made it simple.
What stood out the most was TechBrot Inc’s attention to detail.

§ 02 · Where the controller sits
Bookkeeper, controller, CFO — three roles, one ladder.
The roles aren’t interchangeable, and skipping the middle one is the most common gap in a growth-stage finance function.
Controller — guarantees it’s right
Manages the close, verifies statements, designs controls, supervises the bookkeeping, owns the calendar. The accountability layer. Answers: is it accurate, complete, and on time?
CFO — decides what it means
Forecasting, board reporting, fundraising, capital allocation, strategic decisions. The judgment layer. Answers: what do we do about it? Delivered through fractional CFO.
§ 03 · When controller oversight earns its keep
Signs you need a controller.
Most owners reach for a controller when the bookkeeping is happening but no one is accountable for whether it’s actually right.
Your close is slow or unpredictable.
If you don’t know when statements will land each month — or they’re weeks late — no one owns the close. A controller puts it on a calendar and holds it.
Errors surface after the books are “done.”
If mistakes keep appearing in finished statements, there’s no review layer between the bookkeeper and you. The controller is that review.
You’re the only check on the numbers.
When the owner is the sole control — the only one approving, reviewing, catching — the business has a single point of failure and no real internal controls. That’s a risk a controller closes.
Bookkeeping is split across people or vendors.
Junior staff, a part-time bookkeeper, plus a payroll vendor and a sales-tax vendor — with no one coordinating. A controller supervises the whole function so it works as one system.
You’ve outgrown a bookkeeper but a CFO is overkill.
Plenty of businesses need rigorous oversight and reliable reporting without strategic finance leadership yet. The controller is exactly that middle tier.
A board, lender, or CPA needs reporting they can trust.
External parties need accurate statements on a reliable schedule. A controller owns that output and stands behind it — so it holds up to scrutiny.
§ 04 · What’s included
What controller services actually deliver.
Oversight, accuracy, and accountability — scoped to the size and complexity of your accounting function.
Close management
Owning the month-end close on a published calendar — reconciliations verified, accruals posted, the period locked on time, every month.
Financial statement oversight
Reviewing the P&L, balance sheet, and cash flow for accuracy and reasonableness before they ship — catching errors the bookkeeping process misses.
Internal controls
Designing and operating controls appropriate to your size — approval workflows, segregation of duties, spend authorization, reconciliation review — so the books aren’t protected by one person’s memory.
Bookkeeping supervision
Supervising the bookkeeping function — whether TechBrot’s, your internal staff, or a mix — so the people recording transactions have someone reviewing and directing the work.
Reporting calendar & package
Owning a reliable reporting calendar and the monthly package that goes to leadership, the board, or lenders — consistent format, on schedule, defensible.
CPA & vendor coordination
Coordinating with your CPA on year-end and tax, and with payroll, sales-tax, and other vendors — so the whole finance function is managed, not just the parts.
§ 05 · How engagements work
From assessment to owned accountability.
Four phases, fixed monthly retainer, written scope — built on books that are accurate first.
- PHASE 1
Assessment
A 30-minute call to understand your current finance function, who does what, where the gaps and risks are, and what reporting you actually need. No pitch.
- PHASE 2
Stabilize the foundation
If the books need it, a cleanup first — a controller can’t guarantee accuracy on an unreliable base. We get to a known-good starting point.
- PHASE 3
Install the operating system
Close calendar, control workflows, review checkpoints, reporting package and cadence — the structure that makes the function run reliably, documented and owned.
- PHASE 4
Run & oversee
Each month the close is managed, statements reviewed, controls operated, the package delivered, and the CPA coordinated — with one accountable, signed controller-level specialist practice, named in your engagement letter.
§ 06 · The scope
What a controller is, isn’t, and coordinates with.
A controller is
Accountable for accurate, timely, complete books. Manages the close, reviews statements, designs and operates internal controls, supervises bookkeeping, owns the reporting calendar and package, and coordinates the finance function end to end. The oversight layer between bookkeeping and strategy.
A controller isn’t
A tax preparer — your CPA files. An auditor — audit and compilation are licensed CPA engagements. A CFO — strategy, fundraising, and board leadership are a separate tier. A bookkeeper — the controller oversees that work rather than doing all of it.
A controller coordinates with
Your CPA or EA on year-end and tax. Whoever keeps your books (TechBrot or your own staff). Your payroll and sales-tax providers. Your fractional CFO, if you have one. Your board and lenders on reporting. The role connects the function; it doesn’t do every job in it.
§ 07 · Controller and CFO
Accurate books are what make strategy possible.
The controller and the CFO are different jobs that depend on each other. A CFO building a forecast, a board package, or a fundraising model on books no one has verified is building on sand — which is exactly why a fractional CFO’s first move on a new engagement is to assess the accounting underneath. A controller is the role that removes that problem: the numbers are right, on time, every month, before the CFO ever opens them.
Many businesses run both — controller for accuracy and oversight, fractional CFO for strategy — and where TechBrot delivers the bookkeeping, controller, and CFO layers together, the whole finance stack runs as one system instead of three vendors handing off to each other. As automation handles the routine recording, the controller’s accountability and the CFO’s judgment are where the value concentrates. Explore fractional CFO
Can the controller supervise our existing bookkeeper? Yes. Controller services can supervise an internal bookkeeper, a third-party bookkeeping vendor, TechBrot’s own bookkeeping, or a combination. The controller’s job is oversight and accountability — reviewing and directing the recording work, not necessarily doing all of it. Where TechBrot also provides the bookkeeping underneath, the controller is supervising a function we operate end to end, which removes the handoff friction entirely.

§ 09 · Questions
Controller services questions.
What’s the difference between a bookkeeper, a controller, and a CFO?
A bookkeeper records and reconciles transactions — the operational layer. A controller manages and verifies the accounting function — owning the close, statement accuracy, and internal controls. A CFO sets financial strategy — forecasting, fundraising, board reporting, capital decisions. They form a ladder: the bookkeeper produces the data, the controller guarantees it’s accurate and timely, the CFO interprets it and drives strategy. Smaller businesses often need only a bookkeeper; growth-stage businesses add a controller; complex or capital-raising businesses add a CFO on top.
When does a business need a controller?
When the bookkeeping is being done but no one owns whether it’s accurate and on time. Common triggers: the close is slow or unpredictable; financial statements have errors that surface late; there are no internal controls and the owner is the only check; bookkeeping is handled by junior staff or multiple vendors who need supervision; the business has outgrown a bookkeeper but isn’t ready for a full-time CFO; or a board, lender, or CPA needs reporting they can rely on. A controller is the missing accountability layer.
What’s the difference between a controller and an outsourced controller?
The function is identical; the employment model differs. A full-time controller is an in-house hire: the U.S. Bureau of Labor Statistics puts the median wage for financial managers — the occupation group controllers sit in — at $166,570 a year (BLS Occupational Outlook Handbook, May 2025 data), before employer taxes, benefits, recruiting, or the reporting tooling the role expects. An outsourced or fractional controller delivers the same oversight — close management, statement accuracy, internal controls, reporting — on a fixed retainer of $1,800–$5,000 a month on top of monthly bookkeeping. Actual scope and retainer vary with close complexity, number of entities, reporting cadence, and the controls you need. Most businesses between a bookkeeper and a full-time finance team need controller-level oversight but not a full-time controller’s salary.
Does a controller replace my bookkeeper or my CPA?
No. A controller sits above the bookkeeper and beside the CPA. The bookkeeper still records transactions; the controller supervises and verifies that work and owns the close. The CPA still files taxes and performs any audit or compilation; the controller produces the accurate, CPA-ready books they work from and coordinates with them. TechBrot controller services do not include tax filing, IRS representation, audit, or assurance — those remain licensed CPA work.
How much do controller services cost?
$1,800–$5,000 a month on top of monthly bookkeeping, as a fixed retainer — the rung between monthly bookkeeping ($500–$2,500+/mo) and a fractional CFO ($3,500–$8,000+/mo). Actual scope and retainer vary with close complexity, number of entities, reporting cadence, and the controls you need. When TechBrot also runs the bookkeeping underneath, the controller is supervising a function we also operate. Quoted against written scope; no hourly billing.
