First, let's see if the contractor has large-scale operation. Good cooperation must be based on the contractor's healthy profit model. Huge purchasing volume is the basis of price competitiveness. Large-scale operation can further control and reduce operating costs and provide better services to customers.

secondly, it depends on whether the contractor has a successful canteen management model. Because the canteen business is decentralized, it is impossible for a boss to take care of only one factory, so what can be done to maintain the stability of the quality of products, hygiene and service in each canteen? The contractor shall be required to explain and provide the management mode and inspect the implementation effect of the management mode on the spot.

thirdly, we must inspect the scale of the contractor's investment on the spot, carefully evaluate the contractor's economic strength, and visit the contracted factories to see if their promotional materials are consistent. Because some shell companies only have simple offices, it is not uncommon to borrow factories to visit reverse contracts.
