Stay Organized. Stay Compliant. Stay Ready — Every Quarter.

Not every business needs monthly bookkeeping.
But if you’re serious about your business, you do need clean, accurate, and tax-ready financial records.

Optimum Tax Pro offers Quarterly Bookkeeping Services for business owners who want professional oversight without paying for more frequency than they actually need.

We review and organize your books once every quarter, so nothing piles up, errors don’t compound, and tax season doesn’t turn into a fire drill.

Is Quarterly Bookkeeping Right for Your Business?

Quarterly bookkeeping is a good fit if:

If your business has high transaction volume, payroll complexity, inventory, or fast-moving finances, monthly bookkeeping is usually a better fit—and we’ll let you know that upfront.

  • Your business earns at least $50,000 per year

  • Your activity level is low to moderate

  • You don’t process daily sales

  • You don’t manage inventory

  • You want your books kept current, but don’t need monthly monitoring

  • You want fewer surprises at tax time

What You Get With Quarterly Bookkeeping

Every quarter, we review and organize your financial records to keep everything accurate, consistent, and compliant.

Your quarterly service includes:

  • Reconciliation of bank and credit card accounts
  • Accurate categorization of income and expenses
  • Cleanup of uncategorized or misclassified transactions
  • Tracking of deductible business expenses
  • Quarterly financial reports, including:
    • Profit & Loss Statement
    • Balance Sheet (when applicable)
  • Early identification of issues that could affect taxes or compliance

No backlog. No guesswork. No year-end panic.

How Quarterly Bookkeeping Helps You

Quarterly bookkeeping gives you structure without unnecessary cost.
Instead of waiting until year-end to fix months of issues, you benefit from:

Regular visibility into your finances

Fewer errors and lower cleanup costs

Easier tax preparation and planning

More confidence in your numbers

Financial records that are ready when you need them

Clean books aren’t optional—they’re foundational.

ITIN Application Assistance (When Required)

If you are required to file a U.S. tax return but are not eligible for a Social Security Number, an Individual Taxpayer Identification Number (ITIN) may be required.

We assist with:

  • Determining whether an ITIN is required
  • Preparing the ITIN application as part of your tax filing
  • Ensuring the application is properly submitted with required documentation

ITIN assistance is handled in conjunction with tax compliance, not as a standalone shortcut.

Quarterly Bookkeeping Pricing

Based on Your Business Size

Our pricing is tied to annual revenue and transaction volume, so you’re paying for the right level of oversight—not a one-size-fits-all package. 

Essential Quarterly

$350 per quarter

Best for businesses earning $50,000–$100,000 per year

Includes:

  • Bank and credit card reconciliation
  • Expense categorization
  • Quarterly Profit & Loss statement
  • Tax-ready records
  • Secure online access

Designed for single-entity businesses with simple activity and no payroll, sales tax, or inventory.

Growth Quarterly

$600 per quarter

Best for businesses earning $100,001–$250,000 per year

Includes everything in Essential, plus:

  • Balance Sheet reporting
  • Support for multiple accounts
  • Expense optimization review
  • Written quarterly summary
  • Priority email support

 

This is the most common option for growing, well-run small businesses.

Includes everything in Growth, plus:

  • Advanced reconciliation oversight
  • Bookkeeping aligned with tax strategy
  • Quarterly financial insights
  • Identification of potential compliance or audit risks

     

At this level, quarterly service is reviewed periodically to ensure it remains the right fit.

When Quarterly Bookkeeping Is Not Recommended

If your business earns more than $500,000 per year, quarterly bookkeeping is usually no longer sufficient.

At that stage, businesses typically benefit from:

  • Monthly bookkeeping
  • More frequent financial visibility
  • Ongoing monitoring to reduce risk

If this applies to you, we’ll guide you to the right level of service.

Important Notes About Cleanup & Accuracy

  • If your books are behind or disorganized, a one-time cleanup may be required before quarterly service begins

  • Cleanup pricing starts at $300+, based on how far behind your records are

  • If your business grows into a higher revenue range, your service level may be adjusted

These steps ensure your books stay accurate and defensible.
