Controller Services

Controller services provide accounting oversight, close ownership, review, policy, controls, and reporting at a scope matched to the business. The engagement should distinguish preparation, review, approval, tax, and CFO responsibilities.

What a controller does

• Owns the monthly close, including the deadline and the checklist
• Reviews the bookkeeper work rather than performing it
• Decides accounting treatment: capitalize or expense, revenue recognition, accrual policy
• Designs and enforces internal controls, particularly around cash and payments
• Produces the reporting pack and ensures it reconciles
• Manages the relationship with the tax preparer and any auditor
• Improves process as transaction volume grows

How it differs from bookkeeping

A bookkeeper records transactions and reconciles accounts. A controller is accountable for whether the resulting numbers are right, and for the process that makes them right repeatedly. The distinction is review and ownership rather than execution.

In practice, many small businesses have a bookkeeper and no controller, which means nobody is accountable for treatment decisions or for the close actually happening on time.

How it differs from a CFO

Controller work emphasizes reliable accounting, close, controls, and reporting. CFO work emphasizes financing, planning, strategy, and external stakeholders. The roles can overlap, so buy named deliverables rather than a title.

When you need one

• The close is slipping, or there is no defined close date
• Nobody is deciding accounting treatment, so it is decided by default
• Transaction volume has grown past what one bookkeeper can maintain reliably
• You need internal controls because more people now touch money
• A lender, investor, or auditor has started asking questions the current process cannot answer
• You have multiple entities or locations to consolidate

Fractional controller

As with CFO work, the function is often needed periodically rather than continuously. A fractional arrangement provides review, treatment decisions, and close ownership without a full-time salary, and it is a common intermediate step before an in-house hire.

Own the close calendar

List source deadlines, preparers, reviewers, approvals, dependencies, recurring entries, reconciliations, reporting dates, and open-item escalation. Preserve the status and evidence for every material account.

Review the balance sheet

Reconcile cash, receivables, payables, payroll, taxes, inventory, fixed assets, debt, equity, intercompany, deferred items, and other material balances. Review aging, cutoff, unusual entries, stale items, and later corrections.

Document accounting judgments

For revenue, capitalization, accruals, estimates, leases, foreign currency, consolidations, or other material topics, retain the facts, policy, alternatives, conclusion, source guidance, reviewer, approval, and effective date. Escalate tax, legal, valuation, or assurance questions to the appropriate professional.

Design practical controls

Separate vendor setup, payment preparation, approval, release, recording, and reconciliation where staffing permits. Use named access, multifactor authentication, bank-detail verification, approval evidence, restricted manual entries, and periodic user review.

Deliver decision-ready reporting

Reconcile dashboards and management reports to the ledger. Explain material movement by amount, cause, timing, owner, action, and expected follow-up. Distinguish accounting correction from operational change.

Evaluate fractional scope

Confirm days or cadence, team supervision, systems, close deadline, technical topics, tax and audit coordination, response standard, backup coverage, change orders, security, and exit files. State which work remains internal.

Controller-services checklist

• Close ownership and dates are explicit
• Every material balance has a reconciliation
• Preparation and review are identifiable
• Accounting judgments have written support
• Payment and access controls are tested
• Reports reconcile to the ledger
• Tax, audit, and CFO handoffs are defined

Begin with a diagnostic

Review prior closes, reconciliations, chart of accounts, recurring entries, access, payment workflow, tax and filing calendar, system integrations, reporting definitions, team roles, and open issues. Rank gaps by financial, operational, compliance, and cash risk.

Turn the diagnostic into a close calendar and remediation backlog. Do not hide historical problems inside current entries; preserve the cutoff, correction, approval, and effect on prior reports.

Maintain an accounting issue log

Record the question, facts, amount, accounts, periods, alternatives, applicable policy or guidance, tax and legal dependencies, preparer, reviewer, approver, conclusion, entry, and follow-up. Revisit estimates and recurring judgments when facts change.

Supervise by evidence

Review completed reconciliations, source support, exception aging, correction trends, late tasks, and access changes. Clear review notes explicitly and retain sign-off rather than relying on an undocumented conversation.

Plan the transition to an internal role

If volume or complexity later supports an internal controller, define the job from the actual close calendar, systems, policies, controls, team, stakeholders, and unresolved issues. Use the fractional provider to transfer files, history, and process ownership.

Set authority boundaries

Document who can post or approve entries, change policies, open accounts, alter vendor banking, release payments, communicate with lenders, submit filings, or represent the company to auditors and tax advisers.

Controller review supports management; it does not replace management approval. Exceptions to authority should be written, time-limited, and reviewed after the urgent event ends.

Preserve the approved close package in a controlled, exportable location.

Record material exceptions, the person responsible, the required evidence, the approval path, the due date, and the effect on reporting or cash.
