The plugin YITH WooCommerce Deposits / Down Payments can turn out to be an ace up your sleeve for your shop, mainly if you sell middle- or high-cost products: indeed, the higher the price of your products, the easier you can lose customers because they cannot pay the total amount immediately.
More than a reliable plugin, a guarantee: let your customers leave a deposit and, besides loyalizing them, you’ll see your shop conversion rate increase.
