Old Town Pasadena, California.

Any of This Sound Familiar?

The work that owners keep putting off until the weekend that never comes. We take it off your plate.

Months Behind on the Books

Most owners who call us have a backlog. Sometimes a few months, sometimes a few years. We get the records current and keep them that way. No lecture about how it happened.

Receipts Everywhere

Inbox folders, truck consoles, shoeboxes, text threads with the bookkeeper you had two years ago. We set up a simple way to capture everything and we handle the categorization from there.

No Clear Read on Profit

Bank balance is not profit. We produce monthly reports that show what you actually earned, where the money went, and what is tied up in receivables. You stop running the business on gut feel.

Payroll Eating Your Week

Hours, pay runs, tax deposits, quarterly filings, year-end W-2s. It piles up. We run it start to finish, on time, so your crew gets paid correctly and the agencies stop sending notices.

California Sales Tax Deadlines

The CDTFA does not forget. Rate changes, district taxes, and filing frequencies all shift over time. We track what you owe, file on schedule, and keep the records clean behind it.

Outgrown the Current Setup

Spreadsheets and shortcuts work for a while. Then the business gets bigger and the cracks show up. We build proper systems in QuickBooks so the books match the size of the operation.

Why Work With Us

A few things that shape how we operate and what we bring to every engagement.

20+ Years of Experience

Our founder, Dennis, spent over 20 years in accounting roles at institutional scale, including nearly a decade at an S&P 500 REIT. That depth of experience shapes the way the work gets done for every client, regardless of size.

Systems Thinking

Dennis has built accounting functions from scratch, overhauled payroll processes, and led full software conversions. When your books need real structure, not just data entry, you have someone who has actually done it.

Transparent Pricing

Clear rates and clear expectations from day one. You know what you are paying for and what you are getting. No surprise invoices, no vague scope, no hourly billing games.

Old Town Pasadena

We are based on South Fair Oaks and work with businesses across the San Gabriel Valley and greater Los Angeles. Local reputation matters to us, and that shows up in how we treat every client relationship.
