The big implication of the Covid-19 pandemic that has occurred from 2020-2021, is that more and more consumers are shifting shopping transactions to online marketing media followed by an increase in business actors (sellers) who start businesses in marketplaces, social media. Problems arise with the number of entrepreneurs selling their products through the marketplace, demanding that business actors provide good product quality, speed in processing orders, speed in replying to prospective buyers^ questions, and especially cheap and competitive prices.
One of the competitive factors that will be discussed in this study is the strategy of determining a cheap and competitive selling price by considering the revenue and cost aspects. The differentiating factor of this research is where the researcher raises the behavior of Muslim entrepreneurs in determining cost variables that are different from non-Muslim entrepreneurs.
This study maps all aspects of revenue and costs that have the potential to appear in a product purchase and sale transaction. In this mapping, data was collected through in-depth interviews and focus-group discussions in the period January 2022 to June 2022, with business actors (sellers) in the Shopee and Lazada marketplaces, product/brand owner companies (principals), distribution companies (distributors) supporting products and expeditions in collaboration with the marketplace. This mapping includes elements of the behavior of Muslim entrepreneurs in determining prices. Until now, there are still few publications of scientific articles that include elements of zakat in the model of determining pricing strategies, making this research interesting to do.
The purpose of this research is to be able to provide an overview and mathematical approach to determining the lower limit of competitive product selling prices for sellers in the marketplace to optimize profits and mitigate losses due to errors in pricing.
