Outsourced Controller Services: Benefits, Costs, and How to Choose

What Are Outsourced Controller Services?

Outsourced controller services provide your business with a professional financial controller — without the full-time salary. The outsourced controller manages your accounting function: month-end close, financial reporting, internal controls, compliance, and team supervision.

This is different from outsourced bookkeeping (which handles transaction recording) and different from a fractional CFO (which provides strategic financial leadership). The controller sits in between: ensuring the numbers are right and the reports are meaningful.

What's Included

Monthly Close Management

The controller owns the month-end close process: ensuring all transactions are recorded, accounts are reconciled, accruals are posted, and financial statements are produced accurately and on time. Target: books closed by the 10th of the following month.

Financial Reporting

Monthly financial packages including income statement, balance sheet, cash flow statement, budget-to-actual variance analysis, and management commentary explaining key trends and anomalies.

Internal Controls

Designing and monitoring controls to prevent errors and fraud: approval workflows for expenditures, segregation of duties, access controls for financial systems, and regular reconciliation procedures.

Compliance

Sales tax filings, 1099 reporting, payroll tax compliance, and coordination with external tax preparers and auditors.

Team Management

If you have a bookkeeper or accounting staff, the outsourced controller supervises their work, reviews entries, and ensures quality standards are met.

  5. Scalability: As your business grows, can they scale from controller to full controller services to CFO advisory?
