WooCommerce FreshBooks extension allows you to automatically create your customers in WooCommerce as Clients in FreshBooks, and to optionally create drafts or send invoices for orders. Payments can be synced between invoices and orders, and FreshBooks items can also be linked to WooCommerce products for better reporting.
By having all your data entered into FreshBooks automatically upon order, your customers will have immediate access to download PDF invoices, and you can even send invoices by “snail mail” automatically.
