I, Randal DeHart developed the phrase LMOS, pronounced "Lee Moss" in 1980 as a way to get a better handle on Job Costing And Job Profitability for our construction accounting system. It was done with pencil and paper. It was painful, time-consuming, and boring. However, the reports I could generate were worth their weight in gold! 

Shown below is a later rendition of LMOS as we use it in our QuickBooks For Contractors Template.


Every Cost Code was broken down into Labor, Material, Other, and Subcontractor or as we call it LMOS. For example Demolition is one of the tasks contractors perform. It has four different components for easy tracking of costs and as a foundation piece of Job Costing Reports:

  1. Demolition Labor > How much money was spent using the contractor's Labor?
  2. Demolition Material > How much money was spent on Material?
  3. Demolition Other > How much money was spent on Other costs like permits?
  4. Demolition Subcontractor > How much money on Subcontractors?

Which means we could determine cost of construction down to the granular level, run analysis and we knew which Cost Code tasks should be done in-house with our Labor and which ones should Subcontracted.

We Made Similar Calculations On Materials And Other Costs. We found giving the majority of business to one or two material suppliers and developing relationships with the branch managers of those suppliers we got better pricing and service. Saving 10 minutes a day getting material and streamlining other costs processes added substantial cash flow and profit to the bottom line.

LMOS takes a lot of time and effort to set up QuickBooks but it pays of in the long run.

After a while Contractors who do this know exactly when to use their Labor or Subcontractors. They know where to buy Material, and can track their what Other costs.

LMOS helps them get a better understanding of costs. Without LMOS they have one large cost bucket for every cost code. With LMOS they can review the costs at a granular level and know when it is best to:

  • Perform work with in-house Labor vs. Subcontracting.
  • Buy Material locally vs. ordering it online.
  • Use Other outside services to provide plans and permits.
  • Subcontract outside services vs. investing in tools and equipment rarely used.

In our Construction Accounting Academy we have a class devoted entirely to teaching our LMOS system. It goes into detail how to set up LMOS in QuickBooks desktop.

Although LMOS is primarily used in the Construction industry it can be used in other industries that are project based and they need to break out costs for Labor, Material, Other and Subcontractors.

One example of an industry outside of construction that uses LMOS is the automobile restoration industry. They fix and repair vehicles that have been involved in crashes. This industry has internal Labor working on a variety of damaged vehicles. They purchase Material specific for each project. They have Other costs for example getting a new title or license for a restored vehicle. If they have need of heavy duty tools or equipment they rarely use they will Subcontract the work to another larger vendor.
