Additional payment terms in the self -service laundry franchise business are enforced based on the constraint of the franchisor or the franchisee to execute the contract as mutually agreed upon accurately. The contract offered contains additional payment rates and justifications as a precautionary measure from law enforcement convictions and disputes. As a result, franchise operations run more smoothly and awareness of complying with contractual terms increases over time. However, there are still claims for additional payments that are not contained in the contract agreement but aredirected to pay on a portion of the item so as to raise doubts as to the extent of the obligation to comply with it.Based on the Islamic view, legal issues related to the execution of the contract include the formation of the contract until the demand for additional payment in ensuring that the goals of the contract are achieved. In fact, such additional payments are made non-uniformly depending on the current wants and needs of the franchise company owner.This causes confusion and the effect of treason if done on certain interests continuously to the detriment of the completeness of the contract. Therefore, this study aims to examine the claims for additional payment in self-service laundry franchise business contracts based on Islamic law. Qualitative methods involving library research and interview sessions with respondents were applied in this study to meet the objectives of the study. The results of the study found that the action of additional payment other than that offered in the self-service laundry franchise contract is contrary to the payment method required by Islamic law. In general, the implementation of surcharges in franchise businesses will be more effective based on the proposed solutions in this study.
