- Website: betterbookkeepers.com
Long-Run South Bay Practice
Linda Rost started the shop in 1999 and still leads it from the 90 Great Oaks Blvd office in South San Jose, listed on the practice’s Yelp profile and confirmed by directory entries. The 26-year track record places it well above the five-year threshold this directory uses, and the practice has stayed independent rather than joining a rollup.
QuickBooks-Focused Service Mix
The team handles monthly reconciliations, payroll runs, and QuickBooks file clean-up. They also run setup engagements, short-term clean-up projects, and full-service monthly bookkeeping. Their published service pages call out QuickBooks consulting and outsourced bookkeeping as the two core lines.
Industry Coverage Across the Region
The firm’s site lists work across retail, manufacturing, construction, real estate, dental, and broader service-sector clients, including property-management companies and tutors. That spread fits the mixed small-business base typical of San Jose neighborhoods.
Training Option for In-House Staff
For owners who prefer to keep books in-house, Linda Rost offers QuickBooks training tailored to the client’s file and workflow, so an internal staff member can take over day-to-day entry with the firm available as backup.
2. Marianne Antuzzi Inc.
- Address: 1975 Hamilton Ave, Ste 8, San Jose, CA 95125
- Phone: (408) 626-7005
- Founder / Owner: Marianne Antuzzi
- Operating Since: 1987 (38 years)
- Credentials: Certified QuickBooks ProAdvisor, Certified Bookkeeper, member of the American Institute of Professional Bookkeepers (AIPB)
- Service area: San Jose office at the Hamilton Ave location, plus remote work for Silicon Valley small businesses
- Industries served: Small-business clients across Silicon Valley, including service firms, retail operations, and owner-operated businesses needing combined bookkeeping and payroll
- Website: maprobooks.com
Owner-Operated Since 1987
Marianne Antuzzi launched her practice in San Jose in 1987 and has run it under her own name ever since. The 38-year continuous ownership shows the company has not been absorbed into any larger network and that founder accountability has stayed with the same person across nearly four decades.
Dual Certification Stack
Antuzzi holds the Certified Bookkeeper credential through AIPB and is a Certified QuickBooks ProAdvisor. The combination matters because AIPB certification requires documented experience and continuing education, while the Intuit credential is renewed against current QuickBooks releases.
Bookkeeping and Payroll in One Engagement
The published service list covers accounts payable, accounts receivable, account reconciliations, sales-tax reporting, and payroll. Owners who would otherwise hand payroll to a separate vendor can keep both functions with one practitioner.
Small-Business Silicon Valley Fit
The firm’s marketing focuses on small-business owners in San Jose and the wider Silicon Valley footprint rather than enterprise accounts, which matches the typical client size for an owner-led independent bookkeeping practice.
3. A Reliable Bookkeeping Service
- Address: 1790 Winchester Blvd, Ste 3, Campbell, CA 95008
- Phone: (408) 378-8801
- Founder / Owner: Steven Leikvoll
- Operating Since: Approximately 25 years of operating history per the shop’s own marketing
- Credentials: Certified QuickBooks Pro Advisor; mobile outsourced bookkeeping practice
- Service area: Campbell head office plus on-site and remote service for clients in San Jose, Los Gatos, and surrounding South Bay cities
- Industries served: Small and mid-sized businesses and individuals across the South Bay needing outsourced QuickBooks bookkeeping
- Website: areliableservices.com
South Bay Mobile Model
The practice is based on Winchester Blvd in Campbell, two miles from San Jose city limits, and the practice explicitly markets to San Jose and Los Gatos clients. Their site states they travel to client offices, which suits owners who want a bookkeeper to work directly inside their existing systems.
Owner-Led Independent Shop
Steven Leikvoll is listed as the owner across third-party directory sources, and the firm operates as a standalone QuickBooks-focused practice rather than a CPA-tax-preparation outfit or a national rollup brand.
QuickBooks-Specific Service Line
A Reliable Bookkeeping Service positions itself first as a Certified QuickBooks Pro Advisor outsourced bookkeeping firm. Engagements are built around QuickBooks file maintenance, monthly close work, and ongoing reconciliations rather than tax-return prep.
Long Local Track Record
Public listings put the company’s operating history at roughly 25 years, with more than a decade of continuous client work across Campbell, Los Gatos, and San Jose. That puts it well past the five-year tenure floor used here.

Selection Methodology
This list applies five filters to the San Jose market. First, the practice has to be independent and owner-operated rather than part of a national rollup or franchise brand. Second, the firm must be a Certified QuickBooks ProAdvisor practice with that credential active and visible on its own site or on Intuit’s directory. Third, the company has to have been in business for more than five years, with priority given to firms past the ten-year mark. Fourth, the shop has to position itself as a bookkeeping practice rather than a pure CPA tax-prep shop. Fifth, public address and phone data has to match across at least two independent sources, including the practice’s own site plus a third-party directory like Yelp, the Campbell Chamber, or Intuit’s ProAdvisor finder. Firms appearing only on aggregator review pages without a verifiable street address were dropped before the shortlist stage.
Frequently Asked Questions
Do these firms work with clients outside San Jose proper?
Yes. Linda Rost’s Better Bookkeepers serves the wider Bay Area from its South San Jose office. Marianne Antuzzi Inc. takes on small-business clients across Silicon Valley from the Hamilton Ave location. A Reliable Bookkeeping Service is headquartered in Campbell and explicitly markets to San Jose and Los Gatos clients on a mobile basis.
Are these firms CPA practices or bookkeeping practices?
All three position themselves first as bookkeeping firms built around QuickBooks. They handle monthly books, reconciliations, and payroll-related tasks. Owners who need annual tax-return preparation typically pair these firms with an outside CPA or tax preparer rather than expecting the bookkeeper to file the return.
What does QuickBooks ProAdvisor certification actually cover?
Intuit’s ProAdvisor program certifies practitioners on current QuickBooks Online and QuickBooks Desktop releases, with annual recertification. Each of the three firms here lists active ProAdvisor status. That matters because QuickBooks releases change yearly, and a certified ProAdvisor is the path most independent firms use to stay current on file structure, payroll modules, and reporting features.
How long have these firms been operating?
Marianne Antuzzi Inc. opened in 1987 (38 years). Linda Rost’s Better Bookkeepers started in 1999 (26 years). A Reliable Bookkeeping Service publishes roughly 25 years of operating history. Each clears the five-year minimum tenure threshold this directory applies, and each has remained independent across that window.
