Monthly Accounting Service Pricing Variables

Every business has different monthly accounting needs, so each monthly accounting quote is different. However, your customized fee depends on these variables:

Your Company’s Accounting Activity

Think of this as the volume of work.

How many business transactions do you have on an average month? Your monthly accounting fee can largely depend on how much financial activity your accountant has to work with.

The Complexity of Your Financial Statements

Think of this as the difficulty of the work.

Examples of factors that can be considered complexities include owning multiple business locations, requiring sales tax management, and having multiple bank accounts.

Accounting Service Add-Ons

Here are the secondary services that our monthly accounting clients can add on:

Consulting Services

Employee Retention Credit (ERC) Services

Monthly Accounting Industry Costs

Why does the monthly accounting industry cost what it costs? This image shows the key factors that influence this.

To provide the best service while keeping fees minimized, CSI doesn't follow every industry norm.

For example, on the service side, we keep automation and AI usage at a reasonable level and don't outsource bookkeeping or tax work overseas, unlike most other monthly firms.

Instead, we invest in our staff and technology, and we follow compliance laws closely. We also take advantage of virtual service and standardize our offerings as much as possible.

Basic Payroll Service Pricing Variables

Payroll services charge for different basic payroll specifications. Here are the most critical factors in pricing a basic payroll package:

The Number of States You Will Pay Taxes To

Fees will be added per state that we need to process per pay period. If your employees all live in the same state, you will only need to pay taxes to one state.

Your Selected Pay Frequency

The more often you pay your employees, the more often we process your payroll. This means higher fees per pay period. Our offered pay frequencies include weekly, bi-weekly, semi-monthly, and monthly.

The Number of Employees on Payroll

Payroll fees are heavily influenced by the number of employees on payroll. There will typically be a small fee per employee per pay period.

Payroll Service Add-Ons

There are a variety of optional add-on services that go beyond a basic payroll package. These come at additional costs.

Here are the add-ons that we provide:

Tax Service Pricing

The Value of Year-Round Tax Strategy

Proper tax strategy consists of three things: tax planning, projections, and preparation. Bookkeeping solutions and tax solutions can't capture the full picture the way that monthly accounting does.

All year long, tax strategy (done through monthly accounting) monitors your situation to help reduce the stress of tax season and legally minimize what you owe.

Evolution of Our Fee Structure

Years ago, we charged separately for monthly accounting and annual business taxes. That meant that our clients needed to pay a larger fee during tax season, throwing off their monthly cash flow. This is still the norm for most accounting solutions.

Now, we've spread out the cost of filing annual business taxes. Instead of an annual fee spike, our clients have monthly balance. Fees are consistent, with no filing fees due at tax time.

These graphs are examples that both reflect our average fees in 2025. Fees will vary.

The Cost of Back Taxes & Back Work

If you didn't get your taxes filed this year (and maybe even the years before that), then you'll need us to handle your back work and back taxes.

When there's a gap in your accounting, back work is necessary to get your books caught up while transitioning from one accounting service to another. It's also part of how CSI can guarantee audit-proofed books at no additional cost.

Back Work Fee = # of Prior Months to Work On * Monthly Fee

If you need assistance, we offer back work payment plans.
