BUILT BY PEOPLE WHO'VE BEEN ON THE JOB.
Sulphur Prairie Management, The Construction CFO, is a fractional CFO and accounting firm serving commercial subcontractors and self performing GCs doing $1M to $12M in revenue. Josh Luebker founded SPM after managing 150 or more projects worth more than $2.1 billion combined as a PM and master electrician. Stewart Bohrer runs client delivery as VP of Operations.
Most fractional CFOs learned construction from a textbook. The people running SPM came from job sites. That is not a marketing line, it is why the financial systems built here actually match how subcontracting works: how jobs get bid, how crews get structured, how cash actually moves between the GC and the sub. Between Josh and Stewart, every client gets experienced hands, no junior staff, no scope gaps.
TWO PEOPLE. ONE FOCUS.
Former commercial construction project manager and master electrician. Managed 150 or more projects worth more than $2.1 billion combined, including data centers, military bases, hospitals, and high-rises across multiple states.
He watched profitable subcontractors run out of cash on jobs he was managing. SPM was built to fix that, with financial systems designed around how commercial subcontracting actually works, not adapted from generic accounting practice.
Josh handles every first call personally and is authoring CONTROL: The Construction Financial Operating System. Based in Sulphur Rock, Arkansas.
Josh handles your onboarding. From there, Stewart and his team keep the system running day to day: job costing, WIP reporting, monthly financial reviews, and the follow-through between calls.
Where Josh focuses on bringing new clients in, Stewart owns the ongoing relationship. Before SPM, Stewart spent years in commercial electrical construction operations on large data center builds, so he already knows how the work flows before the financial conversation starts.
No handoffs to junior staff. No gaps between what was sold and what gets delivered.
WHAT THE TEAM HAS DONE AND BUILT.
OPERATIONS FIRST. FINANCIALS FOLLOW.
Every financial system SPM builds starts with the operational reality of how that trade works: how jobs are bid, how crews are structured, how cash flows between the GC and the sub. The accounting follows the operation, not the other way around.
WHAT THE SYSTEM DOES WHEN IT RUNS FOR REAL.
Four client stories. Real trades, real dollar amounts, real outcomes. All fully anonymized.
