If you are looking to start or do any kind of business as a Christian, then you should make sure to consult The Word in everything you do.
Leviticus 25:14 talks about exploiting your customers. According to God, that is not the way business should be done. I went to Bible Gateway to get all the translations of the verse I could in order to get a better understanding of this verse given the content.
Let's look at the word "exploitation" to fully understand its meaning. According to Bing, it is "the action or fact of treating someone unfairly in order to benefit from their work."
Most business owners are opportunists. It is not a bad thing to be an opportunist, as long as the business is done fairly. If you have a shortage of bread in your city and you decide to become a baker because the opportunity is ripe for it, that is not a bad thing. But to sell that bread for more than 100% profit is not fair to your customers. To sell it for less than profitable is not fair to YOU. While seeking to do right by your customers, make sure that you are also holding the customer accountable by making sure he or she does right by you, and vice versa.
