Why Multi-Business Owners Love CSI’s Process & Savings

Written by Miranda Evers | Sep 4, 2025 9:30:00 PM

When you own multiple small businesses (not just one business with multiple entities), accounting can get complicated… even if you outsource. But it doesn’t need to! 

Outsourcing accounting for two or more businesses shouldn’t mean doubling the cost and doubling the headaches. With the right accounting firm, you can streamline processes and even save money.

CSI Accounting & Payroll has provided monthly accounting services to small businesses for nearly 60 years. That means we’ve polished the multi-business experience in these areas:

  • Service agreements.
  • Processes.
  • Costs, including fees and savings.

Multi-Business Service Agreements

When you own multiple businesses and they’re each separate corporations or have different tax IDs, each business will have a separate service agreement with CSI. This is for three reasons:

  • Different businesses may have different service needs. Learn more about our services.
  • Different businesses may be priced differently. Learn more about our pricing.
  • It ensures that service for other businesses will continue as usual if you sell or close one. See how an accountant can help you retire.

Multi-Business Back Work, Monthly Statements, & Tax Processes

Now, I’ll cover processes. Specifically, these processes that matter most to multi-business owners:

  • Back work.
  • Monthly financial statements.
  • Tax strategy.

Back Work

If a business’s bookkeeping or tax filing falls behind or is done incorrectly, it needs to have a professional accountant handle its back work. Otherwise, any bookkeeping moving forward will be incorrect and have a higher risk of an audit.

We handle each business’s back work separately because the project size will vary, and each business’s books should be unique to that business.

Monthly Financial Statements

We generate monthly financial statements for all of our monthly accounting clients. 

When your businesses have appropriately separated finances, we can create separate reports to keep your financial data clear.

Tax Strategy

When you choose monthly accounting with CSI, your bookkeeping and taxes are done under one roof. For consistency, all of your businesses are supported by the same Account Manager and Staff Accountant.

This means you benefit from a year-round tax strategy that can lead to significant savings (something that traditional bookkeeping services and annual tax preparers can’t provide because they don’t work together). That savings potential grows for every business you bring on board with CSI!

Multi-Business Costs: Fees & Savings

It’s time to talk money. Starting with the basics, just like any other client, you’ll pay for each business’s back work (if applicable) and each business’s services moving forward

Then, as I mentioned previously, there’s a large potential for tax savings when multi-business owners work with CSI. (We once saved a client $66,000 in year-end taxes alone.

The best news? You’ll only have one startup fee, no matter how many businesses you bring on board. We’ll waive this for the rest of your businesses, resulting in potentially big savings upfront.
