If the problem is not clear, both parties can negotiate additional terms. Second, see the offer. The quotation for the home improvement company must be clear, fine, and do not go low, and there is a big gap between the final account and the budget. General requirements The final settlement does not exceed 10% to 15% of the budget. Third, the acceptance process should be taken seriously. After the completion of each project, consumers must be cautious in acceptance, and then pass the next step after acceptance. It is best to ask a third party-supervisor company to help with acceptance. Fourth, grasp the payment method.
