Does the process of a retail merchant purchasing from agents via the company's application, with the company paying the agent immediately and the amount being repaid by the merchant in installments with a specified interest, constitute usury (riba)?

It appears that the described installment purchase transaction is Islamically prohibited because its true nature is a loan with interest, which is forbidden usury (riba). It can be rectified by the company purchasing the goods and then selling them on installment to the retail merchant.
