Know every profit cost and then calculate it.
Take the total cost of 10W as an example (hard installation):
Various expenses now account for 1/3, which is 3W;
Gross profit margin: 25%~50% (home improvement), that is, 2.5W-5W；; ;
Cost:10w-3w-2.5w = 4.5w.
But now the decoration industry has gradually differentiated competition, and the obvious ways are: the mainstream of luxury houses, package mode, design banner, designers/design companies, engineering companies/construction teams/professional hydropower subdivision companies, third-party supervision/other service providers, etc. The higher the residential grade, the greater the profit.
Therefore, the actual profit point of the decoration company is: the ability to control the risks that may be brought by factors such as resources, personnel and materials during the construction process. The stronger the control ability, the higher the gross profit can be generated.
