We are a general contractor with multiple specialized divisions (such as electrical, etc.) that carry out specific construction tasks within the company's building projects. Currently, we treat these divisions as independent profit centers to separately accumulate their revenues and costs, and generate division-level profit and loss (P&L) statements.

Recently, we plan to purchase garbage transport trucks and dumpsters for on-site waste disposal, replacing our previous outsourcing services. We hope to systematically track this investment and compare it with past outsourcing expenses to evaluate the investment's effectiveness.

In equipment management, we already have a similar practice: we debit (DR) equipment costs and credit (CR) revenues. Now, we would like to know if any peers use similar methods, and how do you track the financial performance of divisions and equipment?

We look forward to hearing everyone's experiences and suggestions.
