Alternative to early settlement discount
Q: Will it be permissible for one to make an agreement with the supplier, at the onset before purchasing, that for example, the terms will be 30 days with a discount of 5%? There are a few suppliers with whom we have an agreement such as the one described above and we keep to the arranged terms. However, the time period and discount differs from supplier to supplier. If this is not permissible, then what is the solution to rectify the situation?
