Cash on delivery and e-wallets side by side
Vietnam is not a COD-only market. Wallets and bank transfers are growing, and some market studies put COD at around a quarter of payments while a 2022 consumer survey found roughly 70% of online shoppers had used it. Sources disagree because they measure different things: platform payments, survey answers or seller revenue.
For a seller with their own store, the safe assumption is that a large share of your cold-traffic buyers will want to pay when the parcel arrives, especially outside the big cities.
