If your jobs always seem more profitable on paper than they feel in the bank, indirect costs might be the reason.
In this episode of Construction Genius, I sit down with Kathe Barrington, CPA—a fractional Controller and CFO who has worked exclusively with construction companies for over 20 years—to tackle one of the most confusing and costly blind spots in construction accounting: indirect cost allocations, equipment costing, and overhead structure.
Most contractors know they have overhead. Most don’t fully understand what’s in it, how it should be tracked, or how it quietly erodes the margins they think they have. Kathe fixes that.
Key Topics Covered:
- – The real difference between indirect costs, overhead, and G&A—and the debates contractors get into about where to draw the line
- – Why indirect costs are “hidden costs” that distort true profitability if not allocated back to jobs
- – How to cost owned equipment using market rental rates (PAPA, Sunbelt, United Rentals)—and where contractors get lazy
- – Why equipment sitting on a jobsite for storage reasons shouldn’t be charged to that job
- – The 2008 lesson: why treating equipment as a liquid asset almost sank heavy equipment contractors
- – Common chart of accounts mistakes—especially indirect costs buried inside G&A—and how to clean them up
- – Why bank and bonding companies scrutinize your G&A ratio, and what happens if it’s artificially inflated
- – How cost code inaccuracy feeds estimators bad historical data, making future bids less competitive
- – Why estimating and accounting rarely sit in the same room—and why they should
- – What fair overhead allocation looks like across jobs, and how to handle PM pushback
- – Two areas to look at first when hunting for indirect cost leakage: equipment and insurance
- – Why monthly review of indirect allocations is non-negotiable
