Virtual Controller Services: What They Are, What They Do, and How to Choose the Right Partner

As businesses grow beyond basic bookkeeping, the financial complexity increases quickly. Month-end closes take longer, reports become inconsistent, cash flow feels unpredictable, and leadership lacks confidence in the numbers used to make decisions.

This is where Virtual Controller services come in.

At Westport Financial, we provide Virtual Controller services designed to bring structure, accuracy, and financial discipline to growing businesses—without the cost or rigidity of a full-time, in-house controller.

This guide explains:

• What a Virtual Controller is
• What services are typically included
• The benefits and real business results
• How to evaluate and select the right Virtual Controller partner

What Is a Virtual Controller?

A Virtual Controller (also called an outsourced or fractional controller) is a senior accounting professional who oversees your accounting function remotely.

Unlike a bookkeeper—who focuses on transaction entry—a Virtual Controller is responsible for:

• Accuracy and integrity of the financials
• Oversight of the close process
• Financial reporting and analysis
• Internal controls and accounting standards
• Translating numbers into management insight

A Virtual Controller sits between bookkeeping and CFO advisory, ensuring the foundation is strong before strategic decisions are made. Learn more in our previous article, “Fractional Controller Services.”

In simple terms:
Bookkeeping records the data.
A Virtual Controller validates it, structures it, and makes it usable.

How to Find the Right Virtual Controller

Not all Virtual Controller services are the same. When evaluating a provider, look for the following:

1. Experience Beyond Bookkeeping

A true Virtual Controller understands:

• GAAP and accrual accounting
• Financial statement relationships
• Internal controls and risk
• How operations translate into financial results

2. Clear Ownership & Accountability

You should know:

• Who owns the close
• Who reviews the work
• Who answers financial questions
• Who is accountable when issues arise

3. Systems & Process Orientation

Strong Virtual Controllers don’t just “fix numbers”—they build systems so issues don’t repeat.

4. Ability to Scale into Advisory

The best Virtual Controllers naturally bridge into forecasting, cash flow planning, and CFO-level insight as your business grows.
