The main differences between the two pricing models are: (1) the composition of project price is different.
In addition, there is another form of fixed unit price, which implements the lump sum price per square meter of construction, which is often used in unconventional bidding projects.

According to the project price settlement method, the project price is divided into three parts: project advance payment, project progress payment and project completion price.
The project quota pricing method shall not only calculate the quantities during settlement, but also adjust the conversion quota or charge rate according to the policy documents; The bill of quantities pricing method only calculates the quantities during settlement, and the comprehensive unit price agreed upon when winning the bid remains unchanged.
Both parties have great disputes about the basis, principle and amount of the project price.
