The close has no finish line
Reports arrive when someone has time, open questions roll forward, and management never knows which version is final. A controlled close has a calendar, dependencies, reviewer, and sign-off.
The missing middle of the finance team
Outsourced Controller Services That Make the Close Dependable
A controller owns the quality and timing of accounting output. Taxstra reviews the close, strengthens balance-sheet controls, supervises reporting workflows, and gives management a financial package it can trust while coordinating the agreed tax work. CFO-level forecasting is optional.
What changes
1
A named owner for the close
Deadlines, reconciliations, reviews, and unresolved items stop living in separate inboxes.
2
A balance sheet that is reviewed, not assumed
Cash, receivables, liabilities, payroll, debt, and equity are tied out before reports reach management.
3
Reporting built for management
The financial package explains operations and exceptions instead of exporting an untouched software report.
Quick Answer
An outsourced controller owns the agreed close, review process, and reporting standards while your bookkeeper or office manager can keep day-to-day responsibilities. Taxstra can coordinate controller oversight with accounting, tax preparation, and planning. CFO forecasting is optional and separately scoped.
Keep your bookkeeper. Add ownership of the close.
An outsourced controller can work alongside your current bookkeeper or office manager. The engagement defines who prepares each account, who reviews it, who resolves exceptions, and when management receives the reports. Tax preparation and planning can be coordinated with this work without making CFO services mandatory.
- Preparation stays clear
- List the tasks your employee keeps: invoicing, collecting receipts, processing approved bills, and answering operational questions. Give each reconciliation an assigned preparer and reviewer so senior oversight does not turn into duplicated work.
- Review has a defined outcome
- Agree on the accounts to review, supporting schedules, reporting dimensions, and escalation process. A controller should identify an unexplained balance or overdue receivable before management relies on the numbers. Review is not an audit or assurance opinion.
- Accounting feeds the tax work
- Maintain a shared list of asset purchases, owner transactions, entity changes, and open accounting questions. The tax team uses the agreed close and support, with book-to-tax differences addressed in preparation. Name the returns and planning meetings included in the written proposal.
- Add CFO work for a decision
- Use separately scoped CFO support when you need a forecast, hiring analysis, financing model, or expansion scenario. If your immediate problem is late or unreliable statements, start with preparation and controller review.

Processes that survive team growth
The problem this solves
Bookkeeping activity is not the same as financial control
Transactions can be categorized every week while the balance sheet, cutoff, approvals, and reporting logic remain unreliable. Controller work closes that gap.
The income statement gets all the attention
Unreconciled receivables, liabilities, payroll accounts, debt, and owner activity can make profit look plausible while the underlying accounting is wrong. Balance-sheet review is the controller checkpoint.
People compensate for broken systems
One employee remembers the workaround, one spreadsheet fixes the software export, and approvals happen in chat. The process fails when volume rises or someone is unavailable.
How the work moves
A close built as a controlled production process
The controller establishes what must be complete, who prepares it, who reviews it, and how exceptions are resolved before management receives the package.

A business can use several layers at once. The failure happens when nobody knows who is accountable for the final output.

Strong fit
- The business has a bookkeeper or accounting staff but no senior reviewer.
- The close is late, inconsistent, or dependent on one person.
- Management questions whether the balance sheet is correct.
- Lenders, owners, or leadership need a reliable monthly package.
- AP, AR, payroll, or entity workflows need documented controls.
Probably too early or the wrong service
- The only need is a few hours of transaction categorization.
- The company is unwilling to document approvals or system access.
- Historical cleanup is required before a normal monthly close can begin.
- The primary problem is strategy rather than close quality and controls.
- Management wants audited financial statements; that is a separate assurance engagement.
Implementation
Stabilize, document, and run the close
Controller work starts by finding why the current close fails, then replaces workarounds with an owned and reviewable process.
Close diagnostic
Review the chart of accounts, reconciliations, reporting, systems, roles, timing, and recurring errors. Rank problems by financial risk and management impact.
Control design
Build the close calendar, approval map, reconciliation standards, reporting definitions, and issue log.
Parallel close
Run the improved process alongside current operations, measure timing, and fix bottlenecks before relying on it.
Ongoing ownership
Supervise preparation, review accounts, issue the management package, and escalate decisions that belong with the owner or CFO.
Questions business owners ask
Outsourced Controller FAQ
What is an outsourced controller?
An outsourced controller is an external senior accounting professional who owns close quality, reconciliations, controls, reporting, and supervision of the accounting workflow. The role sits between transaction-level bookkeeping and forward-looking CFO leadership.
Can an outsourced controller work with our existing bookkeeper?
Yes. That is a common model. The bookkeeper continues preparing transactions and reconciliations while the controller establishes standards, reviews the work, resolves complex items, and delivers the final reporting package.
When does a company need controller services?
Common triggers include a late close, unexplained balance-sheet balances, multiple preparers without a reviewer, lender reporting, growing AP or AR, several entities, or management decisions that require dependable monthly numbers.
Does a controller replace a CFO?
No. The controller owns accounting integrity and the reporting process. The CFO owns forecasts, capital allocation, financing, and forward decisions. Some businesses need only a controller; others need both layers in an integrated engagement.
Will controller services clean up prior periods?
Cleanup can be scoped as an initial project when prior balances are unreliable. It should be separated from the ongoing close so the company understands which work fixes history and which work maintains the current process.
What should a controller deliver every month?
At minimum: a completed close checklist, reviewed reconciliations, financial statements, comparative or variance reporting, supporting schedules, and a documented list of unresolved items. The package should arrive on an agreed timetable.

Book a free consultationSigns the close needs a responsible owner
An outsourced controller can be useful when the bookkeeper records transactions but nobody reconciles the full balance sheet, reviews exceptions, or delivers dependable reports. The need is defined by the work, not a universal revenue threshold.
| First phase | Deliverable | Acceptance criterion |
|---|---|---|
| Understand the records | Account and system inventory | All material accounts identified |
| Establish the close | Calendar and responsibility matrix | Each schedule has an owner |
| Resolve exceptions | Reconciliation and correction log | Differences supported or explicitly open |
| Deliver reporting | Financial package and commentary | Owner can trace material changes |
| Improve controls | Access and approval recommendations | Responsibilities documented |
A practical first-90-day example
In the first month, inventory systems and inspect reconciliations. In the second, run an agreed close process and address the highest-impact gaps. In the third, evaluate timeliness and recurring exceptions. This illustrates a sequence; the actual timeline depends on the condition of the books.
Agree whether cleanup, payroll oversight, tax-return coordination, or lender reporting is included. Controller support does not automatically include an audit or assurance opinion. If management also needs pricing, hiring, or financing scenarios, define the CFO work separately so each responsibility has an owner.
