Do you understand the true financial performance of your business? At the end of the day you may have insight into what side of the ledger your bank balance sits on. But do you know the story behind those numbers? That’s where a financial team comes in. Working in concert, a CFO, controller, and CPA can help you to understand what’s happening with your bottom line and help you develop and implement strategies that can put you on the path to financial success.

Building a Complete Financial Team

Most businesses turn to an accountant when they are first starting out but quickly developing a team with specialized financial expertise is important. While there are a number of roles that can be part of that team, the three key members are:

  • Chief Financial Officer (CFO)

Develops long-term financial strategies which include everything from when to hire, how to price goods and services, and how to track and manage payments and payouts to strengthen cash flow.

  • Controller

Manages day-to-day financial operations including enforcing financial controls, developing data points, and creating actionable reporting processes.

  • Certified Public Accountant

Builds long-term tax strategies and manages tax filing and reporting.

It is possible that one person can do all of these tasks but they would not be able to provide the same expert level of support, knowledge, and focus that specialists can provide.

Outsourcing Accounting Services for Small Business

One of the biggest misconceptions a business can make is thinking they are not big enough to warrant a full financial team. “Maybe next year” is not a strong financial growth strategy.

To achieve sustainable growth, having a well-rounded financial roadmap in place is imperative. One that is drawn up and overseen by experts. And if you’re not yet ready to add another seat in the company, those experts can be shared through fractional services agreements. Those allow you to get the financial expertise in the areas that are most relevant and important to the current state of your company.

What is a Fractional CFO?

A Fractional CFO will dedicate to you a set amount of time each week/month/quarter as dictated by the needs of a company. They will be able to offer the big picture financial outlook and planning necessary to help you steer the company towards success.

To do this they can look at the current, and projected, financial health of the company and then develop a profit-driven growth strategy. One that they can monitor and manage on a set basis thanks to regular, scheduled connection points.

What is a Fractional Controller?

Fractional Controllers can help the business stay on a steady course toward profitability with regular, continuous oversight. Whether they are offering insight and guidance to the accounting team or monitoring metrics weekly, you can trust them to keep processes moving and call out when corrections are needed.

CPA Outsourcing

An experienced CPA won’t just come in to manage the books and file tax forms. They will bring clarity and updates on changes to the tax code and work with the fractional CFO to develop tax strategies that maximize your return potential and limit your tax liability.

Fractional CFO Services

While a Fractional CFO is not a full-time member of your team, they are still part of your team. They’ll work with you in a way, and with a focus, that best suits your business needs. This means they might bring to you:

  • Big picture business strategies
    How is my business operating from an operational/reporting perspective?
    What does future planning for business financials look like?
  • Daily “process” details
    How should depreciation be calculated?
    What should change with the pricing model?
    When can the team absorb growth?

These are just some of the services you can benefit from with a Fractional CFO. The exact financial plans, and the way that they are implemented, will vary based on the current financial health and strategies of the business and the goals you are trying to achieve.
