Invoice Gateway for WooCommerce – Invoice Payment Gateway vs SSV SmartPay Pay By Bank

INVOICE GATEWAY FOR WOOCOMMERCE – AN EASY INVOICE PAYMENT GATEWAY SOLUTION Add a WooCommerce invoice gateway option for your customers on the checkout. The invoice payment gateway lets your customers checkout without paying and you can invoice separately via your Xero, Quickbooks, MYOB, Reckon Online, or other accounting package. There’s no integration required, you just invoice as you normally would, the plugin lets you record the invoice number which gets added to the customer’s WooCommerce invoice email. Orders get created in Processing status and from there you can generate a separate invoice from your accounting system to have your customer pay outside of WooCommerce. Once you have been paid just add the invoice number to the order then change the Order status to Completed. It’s perfect for situations like wholesale selling where customers are often reluctant to pay large orders online. It’s very similar to a WooCommerce quote at this stage and many people do use it as a quotes gateway. This plugin is also fully compatible with Wholesale Suite’s WooCommerce Wholesale Prices plugin which is the #1 solution for wholesale sales in WooCommerce. The WooCommerce invoicing process with Invoice Gateway For WooCommerce: Customer prepares their order as normal and heads to the checkout. Customer selects the WooCommerce Invoice gateway as their preferred payment option. The order goes into the system as “Processing” status – the customer doesn’t pay anything yet. You, the WooCommerce store owner, send the customer an invoice outside of WooCommerce from your accounting software (such as Xero, Quickbooks, etc). You go back to the order and insert the “Invoice Number” into the field provided and update the order. The customer will get an email. The customer pays the invoice directly to you. When the order is fulfilled, you mark the WooCommerce Order complete (as normal), the customer will see their WooCommerce invoice number on the Completed order email.
