Monona Drive Office in Madison

C M Business Services holds a 6516 Monona Drive office in Suite 115 in Madison, in the 53716 zip code. The Monona Drive address shows up across the practice’s own contact page, the Better Business Bureau profile of C M Business Services, and a Yelp business listing for the practice. Cara Martinson is named as the Owner across the firm’s About page, her LinkedIn profile, and the BBB profile, and the BBB record lists the company as a sole proprietorship.

Almost Three Decade Founder Track Record

Cara Martinson started C M Business Services on November 1, 1997 per the BBB profile, which puts the practice at 28 years under one named owner in 2026. The firm sits well past the five-year minimum bar this directory applies, and the long window under one named owner is rare in the bookkeeping market. The practice earned BBB accreditation on December 9, 2011 and has held that status across the 14 years since.

QuickBooks Training and Consulting Stack

The published service catalog lists QuickBooks training, QuickBooks consulting, and computerized accounting setup as stand-alone services alongside ongoing books. The team supports owners who want to keep books in-house with periodic training sessions, and the practice handles full outsourced bookkeeping for owners who would rather hand the books over. That dual track lets a Madison owner pick a level of involvement and shift between the two as the business grows.

Small Business Service Mix

The published mix runs past basic monthly bookkeeping to payroll management, payroll processing, financial reporting, year-end tax organization, job costing, and accounts payable and accounts receivable management. The firm leans on small businesses in the Madison metro, including a published payroll services page for owners who want payroll on the same vendor as the books. That breadth lets a closely held client keep books, payroll, and year-end prep with one Monona Drive practice rather than running parallel vendor contracts.

2. Wisconsin Bookkeeping, LLC

• Address: Madison, WI (Madison metro, exact street address not published; remote-first practice with in-person meetings on request)
• Phone: (608) 535-9292
• Founder / Owner: Tony DiMaggio (Founder)
• Operating Since: 2009 (17 years)
• Credentials: Tony DiMaggio is listed as a QuickBooks Certified ProAdvisor on the Intuit Find-a-ProAdvisor directory; the company requires every staff member to hold QuickBooks ProAdvisor certification per the shop’s own homepage
• Service area: Madison-based remote practice that supports small and mid-sized businesses across the United States via cloud-based QuickBooks Online files
• Industries served: Small and mid-sized businesses across multiple sectors per the practice’s About page, with no restriction to a single niche
• Website: wibookkeeping.com

Madison Remote First Practice

Wisconsin Bookkeeping, LLC works from a Madison base and describes itself as roughly 90 minutes west of Milwaukee per the firm’s homepage. The (608) 535-9292 phone and the Madison base appear across the company’s homepage, the shop’s About page, and the Intuit Find-a-ProAdvisor directory entry for Tony DiMaggio. Tony DiMaggio is named as the founder on the practice’s About page and is the QuickBooks Certified ProAdvisor of record on the Intuit directory listing.

Founder Track Record Past 15 Years

Tony DiMaggio launched Wisconsin Bookkeeping in 2009 per the firm’s own About page, which puts the practice at 17 years under one named founder in 2026. The firm sits well past the five-year minimum bar this directory applies, and Tony DiMaggio has stayed in the founder role across the full window. The practice has worked with businesses in many industries since 2009, with cloud QuickBooks Online files as the standing platform.

All-Staff ProAdvisor Rule

Wisconsin Bookkeeping makes a public rule that everyone on staff must hold QuickBooks ProAdvisor certification, which the company states on its own homepage. That rule rules out junior or uncredentialed bookkeepers handling client books without the credential, and it keeps the team aligned on one platform and one credential standard. The published workflow runs on QuickBooks Online files exclusively, which fits owners who already use QuickBooks Online or who want to migrate onto it.

Outsourced Controller Services

The published mix runs past basic bookkeeping to accounting and financial controller services, which lets owners hire the practice for higher-level financial oversight rather than just transaction recording. The firm meets clients via phone, email, Zoom, or in-person at the office on request, which fits a remote-first workflow. That setup lets a Madison or out-of-state owner keep monthly close, financial reporting, and controller-level oversight with one practice on a cloud platform.

The firm sits 18 years past the 2008 founding date, well past the five-year minimum bar this directory applies, and Kimberly has stayed in the named-owner role across the full window. Her published specialties include QuickBooks ProAdvisor, Peachtree, and Xero.

Dual ProAdvisor and AIPB Credential Stack

Kimberly Crowley holds Certified QuickBooks ProAdvisor status and AIPB membership per the practice’s own About page, which pairs platform-specific QuickBooks training with a broader bookkeeping body of knowledge through the American Institute of Professional Bookkeepers. The firm provides QuickBooks setup, cleanup, training, and support as stand-alone services alongside full-charge engagements. That dual credential stack fits owners who want both QuickBooks-specific work and broader bookkeeping discipline on the same vendor.

Three Industry Focus Plus Nonprofits

The firm published a Service, Retail, and Construction industry focus on its homepage, with explicit support for small home-based, medium-sized, and nonprofit clients. The published mix covers full-charge bookkeeping, billing and accounts receivable, accounts payable, general journal entries, bank reconciliation, end-of-period reporting, quarterly filings, sales tax filings, and payroll. That published industry focus plus nonprofit support lets a Madison-area owner in service, retail, or construction keep books, payroll, and quarterly compliance work with one Belleville practice.

All three firms appear as independent, founder-led, or owner-led practices and not as franchised or rolled-up brands such as Bench, Pilot, QuickBooks Live, BELAY, Bookkeeper360, Bookminders, Supporting Strategies, Bookkeeper.com, or 1-800Accountant. None of the three firms overlap with the three Milwaukee-market firms covered in the companion 030-milwaukee-wi.md directory (The Giersch Group, Diversified Management Services, Amber’s Accounting & Bookkeeping).

Selection Methodology

This list applies four filters to the Madison market. First, the shop has to be independent, family owned, or founder led rather than part of a national rollup or franchise brand. Second, the practice must show active QuickBooks credentials or a QuickBooks-centered practice, with that focus visible on its own site or on a third-party directory. Third, the firm has to have been in business for at least five years, with priority given to firms past the ten-year mark. Fourth, the company has to position itself as a bookkeeping practice rather than a pure CPA tax-prep shop. Public address and phone data also had to match across at least two independent sources, including the shop’s own site plus a Better Business Bureau record, a chamber of commerce listing, a Dun & Bradstreet entry, the Intuit Find-a-ProAdvisor directory, or another third-party business profile. National rollup brands such as Bench, Pilot, QuickBooks Live, BELAY, Bookkeeper360, Bookminders, Supporting Strategies, Bookkeeper.com, and 1-800Accountant were excluded by design, since this directory targets locally owned shops in the Madison market.
