Why Client Advisory Services (CAS) Are the Future of CPA Firms

The accounting profession & # 39 ;s landscape is changing quickly and drastically from ever before. The need for CPA firms to deliver traditional compliance services as their only means of long-term growth is no longer possible. Today's clients are looking beyond just traditional bookkeeping, tax preparation and year-end reports; they want business intelligence insights, dynamic forecasting capabilities, and strategic direction. They are looking for advisors who will become trusted partners to help them make sound business decisions through advice and guidance.

The changes taking place in the marketplace today represent a tremendous opportunity for CPA firms throughout the United States via the use of Client Advisory Services (CAS).

In many cases, CPA firms previously relied solely on traditional tax and audit revenue streams, however many have begun to utilize Financial Advisory Services, Outsourced Accounting Services (OAS), Virtual CFO Support, Cash Flow Forecasting, KPI Reporting and Technology Consulting in order to grow their professional service offerings.

When CPA Firms take advantage of the opportunities afforded to them by successfully implementing CAS, they achieve two primary benefits; increasing profitability and enhancing client retention while simultaneously improving their firm valuation and establishing scalable recurring revenue streams.

While technology has positioned CPA Firms to build successful CAS firms, a firm must also possess operational capacity, specialized talent, efficient operating practices & processes, and an ability to scale quickly without exhausting internal resources.

In addition, CPA Firms that successfully build CAS practices increasingly use strategic outsourcing and offshore staffing models to gain a competitive advantage in today's accounting profession. An abbreviation for Client Advisory Services, which is a large group of accounting & strategic financial services that businesses receive on an ongoing basis from accounting firms.

The focus of CAS is to support clients in making forward-looking decisions using current financial information, as opposed to historical information as is common in traditional accounting.

Types of services that fall under CAS include:

  • Reporting and preparing the financial statements of the organisation;
  • Building Key Performance Indicators (KPIs) dashboards to monitor performance throughout the year;
  • Preparing cashflow forecasts for both short and longterm planning
  • Assisting with budgeting and planning
  • Providing Virtual Chief Financial Officer (CFO) type support
  • Providing Payroll administration support
  • Providing consulting for technology to be used by the organisation
  • Providing sales & use tax compliance support
  • Managing the organisations bookkeeping and accounting departments
  • Assisting with Financial Planning & Analysis for all operations;
  • Providing business advisory services.

Essentially, Client Advisory Services shift the focus of Accountants away from compliance activities and into the role of strategic business partners to the organisations they serve.

Reasons Behind The Rapid Expansion Of CAS In America

More than just compliance, clients are now asking for their accountants to provide ongoing support rather than just seeing them once a year. Examples of the types of questions being asked include: Are we able to hire more employees? Which department is losing money? What steps can we take to improve our cash flow? Are we pricing our services adequately? What needs to happen before we seek funding? As these kinds of questions emerge, CAS will be able to help the firm to consistently provide clients with answers.

Advancements in technology and AI are drastically changing the way firms perform repetitive tasks, such as data entry, reconciliations, and tax preparation processes, and will continue to do so. Due to the decline in revenue associated with compliance work being commoditized, firms have a need for additional higher value services to continue making profits. CAS provides premium advisory revenues which are considerably more difficult to be replaced with automation.

Since tax season is seasonal, CAS provides recurring monthly revenue. As a result of this, accounting firms will have a predictable cash flow which will help to enhance the long-term relationships with their clients. Many firms offering CAS now have moved to a monthly subscription billing approach as opposed to billing on a project basis.

Real-time Financial Visibility Is Essential for Businesses

Due to recent changes in economic conditions, inflation rates, tax laws, and fluctuations within the marketplaces, business owners are looking for methods to manage their businesses better and are looking for assistance from their accounting professionals.

For a company to survive and grow, it needs access to real-time financial information. With the use of a CAS model, CPA firms can become integral partners with their clients in making key decisions.

The greatest difficulty in developing a CAS practice

While the potential for growth is enormous, scaling CAS is difficult for many companies.

The primary issue is a lack of available resources.

Throughout the United States, CPA firms are dealing with:

  • Exhaustion of employees
  • Increased salaries
  • Limited talent pool
  • Significant turnover and difficulty attracting experienced employees
  • High levels of seasonal workload.

Because of these reasons, it is very costly and challenging to create a total in-house CAS team.

For this reason, many firms have turned to Offshore Accounting Companies and Outsourcing companies for help with their CAS growth.

Offshore Accounting as a Scale Resource for CAS Firms

While outsourcing was previously focused mainly on cost, modern outsourcing also concentrates on scale, collaboration and operational efficiency.
