Petroleum Marketers Service

What Petroleum Marketers Service does

Petroleum Marketers Service, Inc. (PMSI) is a privately held professional services firm founded July 19, 1946, specializing in the brokerage, appraisal, and consulting needs of petroleum distribution businesses in the United States. The firm operates six core service lines: business brokerage (matching buyers and sellers of petroleum businesses), formal business valuations for financing, estate planning, and court proceedings, consulting on M&A and operational matters, certified general real estate appraisal of petroleum properties, market analysis, and buyer representation. PMSI's primary customers are owners and prospective buyers of convenience stores, service stations, travel centers, tankwagon businesses, oil jobbers, and propane companies, plus lenders and financial institutions requiring certified appraisals.

The company generates revenue through transaction-based brokerage fees on closed petroleum business sales and per-engagement fees for appraisals, consulting, and market analysis engagements. Pricing is not publicly disclosed and is quoted per engagement. PMSI employs 1–10 people and is headquartered at 6632 Telegraph Road #140, Bloomfield Hills, Michigan. Its go-to-market is sales-led, relying on direct client consultations, industry referrals accumulated over 78+ years, and a partnership with national valuation firm Gravitas Valuation that extends service reach across all 50 states.

Following a recent ownership transition, Eric Sobotka (MAI, founder of Gravitas Valuation) serves as Managing Director while long-time owner Mark Montag continues as Founding Advisor. The firm has no proprietary technology platform, no disclosed funding, and no public listing; it operates as a boutique advisory practice with deep, narrow specialization in petroleum distribution transactions rather than a scaled intermediary.

Broad incumbents

• Cushman & Wakefield (Valuation & Advisory): Global commercial real estate services firm with a dedicated Valuation & Advisory practice performing certified appraisals of special-use properties, including petroleum-related real estate. Competes with PMSI's real estate appraisal offering at the upper end of the market.
• Murphy Business & Financial Corporation: A large business brokerage and valuation franchise network. Overlaps with PMSI in M&A intermediation and business valuations, but without vertical specialization in petroleum distribution.
• Transworld Business Advisors: A major business brokerage and M&A advisory franchise with nationwide coverage. Competes for the same pool of buyers/sellers of small petroleum businesses but offers petroleum as one of many industries served.
• Sunbelt Business Brokers: The largest business brokerage franchise network in North America, intermediating Main Street and lower-middle-market transactions across all verticals including petroleum. Competes with PMSI for general business sales but lacks PMSI's 100% petroleum specialization.
• VR Business Brokers: A national business brokerage franchise that handles main-street and lower-middle-market transactions including service stations and convenience stores, overlapping with PMSI's brokerage service line.
• JLL Valuation Advisory: Major global CRE services firm providing appraisal and valuation services across asset classes including special-use and petroleum-related properties, competing with PMSI for lender and institutional appraisal mandates.
• Colliers International Valuation & Advisory: Global CRE services platform with a substantial valuation and appraisal practice covering special-use assets. Overlaps with PMSI's certified general appraisal services for petroleum properties.

Others

• BizBuySell: The largest online marketplace for buying and selling small businesses in the U.S., including petroleum businesses. Functions as an enabling/distribution channel that competes for listing visibility rather than full-service intermediation.

Emerging players

Direct peers
