CS-Cart Single Seller Checkout enables customers to purchase products from only one vendor at a time, ensuring a streamlined and hassle-free checkout experience.
With this add-on, store owners can prevent multi-vendor orders by restricting the cart to products from a single seller. Vendors can also manage their own payment methods, while admins retain full control over the checkout process, making it ideal for marketplaces that prefer separate vendor-based orders.
Configure Seller Payment Settings
Admins can configure payment method settings and define how seller-specific payment options will be managed across the marketplace.
