Fractional CFO & Controller Services for Wineries and Companies in Napa, Sonoma, and Northern California Wine Country

Fractional CFO Services in Wine Country

Fractional CFO and controller services for Wine Country construction, contractors, distribution, manufacturing, and service businesses.

Napa / Sonoma / North Bay

Serving Wine Country's family-owned mid-market.

Vessel Advisors supports businesses across Napa, Sonoma, and the broader Northern California Wine Country — multi-generational wineries and vineyards, hospitality and resort operators, agricultural businesses, and the construction and services firms that support Wine Country's economy.

Wine Country runs on multi-generational family businesses with long capital cycles, deep relationship economies, and the unusual operational profile of agriculture, hospitality, and manufactured product all in one P&L. Finance leadership here looks different than in most metros.

The Market

Wine Country businesses look like nothing else in the mid-market.

A mid-market winery is simultaneously an agricultural operation, a manufacturing business, a hospitality brand, a direct-to-consumer commerce company, and often a real estate holding — frequently inside the same family entity structure. Inventory cycles run years rather than months. Capital is locked up in vines, barrels, and inventory long before revenue lands. Generational handoffs are an active conversation in most family-owned vineyards. Finance leadership for a winery looks unlike anything else, which is part of why most generalist fractional CFO firms struggle here.

What we see most:

  • Multi-generational vineyards and wineries managing capital structure, inventory, and succession across complex entity structures.
  • Hospitality operators — resorts, inns, restaurant groups, tasting room operations — with multi-unit reporting needs.
  • Direct-to-consumer wine commerce and wine club operations layered on traditional distribution channels.
  • Agricultural services, equipment, and viticulture businesses serving the broader wine industry.
  • Construction and trades businesses serving Wine Country's hospitality and luxury residential markets.

Industries

Where we work most in Wine Country.

Wineries and vineyards

Multi-generational winery operations — production, hospitality, direct-to-consumer, and distribution layered together. Long inventory cycles, complex capital structure, multi-entity consolidation, and family succession planning are the recurring work.

Hospitality and resorts

Resorts, inns, restaurant groups, tasting-room operations. Multi-unit margin discipline, seasonal labor economics, and the team development that lets family-owned hospitality scale beyond founder bandwidth.

Agriculture and viticulture services

Vineyard management, equipment, custom harvest, and agricultural input businesses serving the broader wine industry. Customer concentration, seasonal demand, and asset-intensive working capital are baseline.

Construction and luxury residential

Commercial contractors, custom residential builders, and the trades businesses serving Wine Country's hospitality and luxury home markets. WIP accounting, project-level profitability, and capital structure work.

Wine Country Taxes and Compliance

Santa Rosa, Petaluma and Sonoma set minimum wages above California's. Napa's sales tax rose to 8.75% in 2025.

Each of the four cities taxes business its own way: on receipts, on headcount, or on estimated receipts trued up at renewal. Wineries, hotels and builders also carry California's rules on inventory, tips and retention.

Taxes

Sales tax

10.25% in Petaluma and Sonoma, 10.00% in Santa Rosa, 8.75% in Napa

All four rose on April 1, 2025: Napa from 7.75%, Santa Rosa from 9.75%, Petaluma from 10.00% and Sonoma from 9.50%. Sonoma County's Measure I added 0.25% countywide, and the city of Sonoma doubled its own tax to 1.00%.

Santa Rosa business tax

$1,000 plus a rate per $1,000 above $1 million

Below $1 million of gross receipts, Santa Rosa charges a flat $200 to $800. Above it, the rate is $0.34 per $1,000 for retail, wholesale, manufacturing and headquarters, $0.84 for services and $1.68 for professions.

Petaluma business tax

0.016% to 0.048% of gross receipts

Retail, wholesale and manufacturing pay 0.016%, services and property rental 0.032%, and professionals 0.048%, with a $45 minimum plus the $4 state fee. Renewals are due March 31.

Sonoma business license tax

A license tax set by headcount

The city of Sonoma taxes businesses by the number of people they employ, with separate schedules for retail and services, professionals, manufacturers and contractors. The flat amounts adjust each July 1 with California per-capita income, by up to 8% a year.

Napa business license tax

Estimated receipts, trued up at renewal

Napa taxes most businesses on estimated gross receipts at a rate set by business type, then adjusts the bill to actual receipts at renewal. HdL administers the tax for the city.

Employers

Minimum wage

$18.31 in Petaluma, $18.21 in Santa Rosa

Santa Rosa's rate applies at every employer size and rose from $17.87 this year. Petaluma has already posted $18.93 for 2027, and its learner rate is $15.56, rising to $16.10.

Sonoma minimum wage

$18.47 at 26 or more employees

Employers in the city of Sonoma with 25 or fewer employees pay $17.38. Either rate covers anyone who works more than two hours in a week inside the city.

Tipped staff

Tips can't count toward the minimum wage

California allows no tip credit, so tasting-room, restaurant and hotel staff receive the full hourly minimum in wages, with tips on top.

Commuter benefits

A commuter option at 50 full-time employees in Napa

Napa is inside the Bay Area Air District, whose commuter rule has applied since 2014. An employer there with 50 or more full-time employees provides a commuter option such as pre-tax transit or a vanpool.

Questions Wine Country owners ask

Does a winery pay property tax on wine aging in barrels?

No. California exempts business inventories from property tax, and wine held for sale is inventory. The county assessor taxes equipment and fixtures as of the January 1 lien date, and a winery whose taxable equipment cost $100,000 or more files Form 571-L between January 1 and April 1. More on how we work with family-owned businesses.

How do Santa Rosa and Petaluma tax a contractor?

Santa Rosa charges contractors and land developers $1,000 plus $1.09 per $1,000 of gross receipts above $1 million, with flat amounts below that. Petaluma taxes contractors at 0.032% of gross receipts. More on our work with builders and contractors.

Does the 5% retention cap apply to a custom home?

No, unless the project is mixed-use or more than four stories. The cap on private retention, for contracts entered from January 1, 2026, leaves out homes and other residential projects of up to four stories that aren't mixed-use. A winery building or hotel falls under it, with retention held to 5% of each payment and of the contract price, and no subcontract above the prime contract's percentage.

Does a Petaluma mailing address mean Petaluma's taxes apply?

Not always. The city says many Petaluma addresses are in unincorporated Sonoma County, where the sales tax is 9.25% instead of 10.25%. Petaluma's own rates apply inside city limits.

Is Santa Rosa's business tax capped?

Yes. A 2024 ordinance set the maximum at $10,000 and indexes it each December, starting in 2025, by 2% to 4%. Headquarters are taxed on their cost of operations rather than on receipts.

How does the city of Sonoma count employees for its license tax?

It uses the average number of people employed during the prior calendar year. A winery or hotel with seasonal staff is taxed on its yearly average, not its harvest or summer peak.

Figures verified October 2026 against the California Revenue and Taxation, Labor and Civil codes, the California Department of Tax and Fee Administration, the Department of Industrial Relations, the Bay Area Air Quality Management District, the Santa Rosa City Code, the Sonoma Municipal Code and the cities of Santa Rosa, Petaluma, Sonoma and Napa. This is general information, not tax or legal advice.

Wine Country Finance Talent

The Santa Rosa–Petaluma metro has a pool of 800 financial managers.

That is the Bureau of Labor Statistics count of financial managers, the category that covers controllers and finance directors, across Sonoma County. Their median pay is $164,140, level with the national median of $166,570, and the top tenth earns $301,550 or more. Accountants and auditors there earn $94,690 at the median.

Sonoma County has 589 business locations with 50 to 499 employees, and Napa County has 261. A winery, hotel group or builder can get CFO judgment without hiring one of those 800 away from another employer.

The Financial Discovery Assessment shows you what’s working, what’s missing, and the plan to get where the business needs to go.

Every Assessment applies the same structured examination — accounting systems and technology, processes and procedures, team members and team structure, and team-member will-skill — refined across hundreds of engagements in businesses that look like yours.

The output is the Financial Heat Map System: dollarized findings, hidden inefficiencies, and a sequenced plan. It’s presented at the Executive Action Meeting, where your stakeholders review findings and recommendations in non-clinical, non-technical language they can act on.

We’ve walked into hundreds of businesses at the stage yours is in now. We know where to look. We know how to fix what we find.
