WooCommerce Smart Checkout plugin

Our WooCommerce Smart Checkout plugin allows you to accept payments via Viva Smart Checkout in your WooCommerce store.


This plugin uses our Smart Checkout solution. Please see our video overview of Smart Checkout’s main features and benefits:


1 Please note: If offering installments, the value provided by the merchant is not the number of installments the customer will select, and it is not mandatory for the customer to select installments at all. The process is as follows:

  1. The merchant indicates the maximum number of installments they wish to offer to the customer
  2. It is then up to the customer whether they pay with or without installments
  3. If the customer decides to pay with installments, they are able to select the number of installments (up to the maximum specified by the merchant)

User experience


This plugin uses our Smart Checkout solution. Customers are redirected from your checkout page on your WooCommerce store to Viva Smart Checkout to pay, and after the customer pays, they are redirected automatically back to your WooCommerce store.
