WHERE THE CASH GOES MISSING.

Job costing, WIP reporting, and cash flow writing for commercial subcontractors doing $1M to $12M, from a former project manager and master electrician.

QUICK ANSWER

This blog covers job costing, WIP reporting, overhead recovery, and cash flow for commercial subcontractors and self-performing general contractors doing $1M to $12M in revenue. Every post is written by Josh Luebker, a former commercial construction project manager and master electrician who managed over 150 projects worth more than $2.1B combined before becoming a fractional CFO. The client stories include the real figures, and the explainers link to the page that treats each subject in full.

A blog post answers one question in five minutes. The system pages behind it answer the question the reader has after that. Each post links to the one page on this site that covers its subject completely, so nobody has to guess which of two similar pages is the definitive one.
