WHY THIS SYSTEM READS DIFFERENTLY

Most construction accounting is written by accountants who learned construction second. This was written the other way round. The cost categories match how a bid really gets built, the equipment rate covers what a machine costs to keep, and the monthly cadence asks as little of the owner's time as possible while still giving them the same financial picture they would have if they built it themselves.

Josh Luebker is a master electrician and former commercial construction project manager who now runs the finance side for contractors. He managed more than 150 projects worth over $2.1B, then founded SPM The Construction CFO (Sulphur Prairie Management, LLC), an outsourced finance and CFO firm for subcontractors doing $1M to $12M. He is the author of CONTROL: C.F.O.S. Construction Financial Operating System, a #1 Amazon bestseller in Construction Industry and Home Improvement Estimating, and publishes free benchmarks for 48 trades at https://runoncfos.com.

QUESTIONS

What people ask

Who is Josh Luebker?

Josh Luebker is a master electrician and former commercial construction project manager who now runs the finance side for contractors. He founded SPM The Construction CFO (Sulphur Prairie Management, LLC), an outsourced finance and CFO firm for subcontractors doing $1M to $12M, and wrote CONTROL: C.F.O.S. Construction Financial Operating System. More at https://constructioncfo.net.

Why should a contractor listen to him on accounting?

The system was built from the field side, not the ledger side. The words in the cost codes are the words the crews already use, which is the difference between a structure people follow and one they never use.

What is the relationship with SPM The Construction CFO?

Run On CFOS is the system, the book and the templates. SPM The Construction CFO is the firm that installs it for owners who would rather buy the result than build it. Two businesses, one method.
