âIntroducing a cod fee was one of the best decisions for our store. Before the fee, we faced frequent COD order returns, which led to wasted shipping costs and tied-up inventory. After adding a small Cash on delivery fee using TMD OpenCart COD fee extension, we saw a noticeable drop in low-intent orders and unnecessary returns. The customers who still choose COD are more committed, and the extra fee helps offset our delivery risk. Itâs improved our cash flow and made our operations much smoother.â

6. Real-Life Use Case: How a Store Reduced COD Losses by 20%
Fashion Store Example
A dress store sells dresses on the web. Customers often opt for COD, but 10% of orders are rejected on delivery, resulting in return shipping and packaging fees. By charging an additional âč50 for COD, fewer low-intent customers opt for COD, and the additional fee offsets returns losses.
Electronics Shop Example
A shop selling electronics provides COD for mobile accessories. Most customers place multiple orders and reject delivery if they have second thoughts. The shop charges a minimal COD, which deters occasional buyers and reimburses additional shipping charges in case of returned orders.
Rural E-commerce Example
A rural grocery vendor accepts COD since most customers do not use electronic payments. COD failures result in the cost of money. The store charges a nominal COD charge, which assists in recovering the cost of money due to failed deliveries and motivates genuine buyers only.
Customized Gift Store
A store that sells customised mugs and T-shirts has issues when there are COD returns because the products canât be resold. Charging a COD fee decreases such occurrences and recovers a portion of the expense on each customisation.
