Why would a vendor require cash on delivery?

A vendor may require cash on delivery (COD) to minimize financial risk, ensuring that they receive payment before transferring ownership of the goods. This method protects them from potential issues like payment fraud or chargebacks associated with credit transactions. Additionally, COD can appeal to customers who may not have access to credit or prefer not to use electronic payment methods. Overall, it helps vendors maintain cash flow and reduce the likelihood of unpaid invoices.
