Woo Invoices – Quotes and Invoices



This Woocommerce extension acts as the middle-man between the Woocommerce plugin and Sliced Invoices plugin, allowing you to easily create invoices and quotes from Woocommerce orders. Both plugins are free and both plugins are required.


  • Automatically create quotes from Woocommerce orders
  • Automatically create invoices from Woocommerce orders
  • Invoices and quotes can be created from the back end (admin creating the order)
  • Invoices only can be created from the front end (upon client checkout)
  • Adds ‘Pay by Invoice’ as a Checkout option
  • Enable default payment methods on invoices
  • Enable invoices only for certain shipping methods
  • Include instructions and a link to the Invoice in emails
  • Easily print quotes & invoices to PDF by using the PDF invoices extension
  • The PDF invoices extension also allows clients to print their quotes and invoices
  • With the PDF extension installed, the PDF will also be attached to the Woocommerce emails that go to the client


Woocommerce and Sliced Invoices are both ecommerce plugins that have very different uses and different functions, but there is also some overlap with some of their features. This plugin takes some features of Sliced Invoices and some features of Woocommerce to achieve an extremely flexible ecommerce setup that can be used in many, many different ways.

You can still use Sliced Invoices independantly of Woocommerce and vice versa.

So how do the plugins work together?

Admin Area

  • Automatically create a Quote or an Invoice by creating a Woocommerce Order
  • Invoices are created when the Woocommerce Order Status is set to Invoice (the Invoice is now tied to the Order)
  • Quotes are created when the Woocommerce Order Status is set to Quote (the Quote is now tied to the Order)
  • Editing the Order will edit the tied Invoice or Quote
  • You can convert a Quote to Invoice by simply changing the Order Status to Invoice
  • Mark an Invoice as Paid by changing the Order Status to Completed
  • Quotes and Invoices will get their statuses updated depending on the status of the Order

Front End

  • A user can choose the ‘Pay via Invoice’ option when they check out
  • An order is created as per normal, and an invoice is also generated
  • Uses the Woocommerce Billing Details as the ‘To’ address on the Invoice or Quote
  • Uses the Woocommerce Order ID as the ‘Order Number’ on the Invoice or Quote
  • Payment Methods from Sliced Invoices can be added to the Invoice (bank, cheque, PayPal, generic)

Emailing the Invoice or Quote

There are a couple of different ways you could send the client the Quote or Invoice.

  • Via the Order Actions section from within the order (this will send a Woocommerce styled email)
  • Via the Sliced Invoices Quotes or Invoices menu (this will send a Sliced Invoices styled email)


Scenario 1 – Creating Invoices

You simply need to create invoices from Woocommerce orders.

  • User adds products to cart
  • User goes to checkout and chooses ‘Pay via Invoice’ option
  • Sliced Invoices creates the Invoice in the background
  • User is taken to the ‘Order Received’ page. Instructions and a ‘View The Invoice’ button are shown
  • User can view the Invoice and see the payment methods on the invoice that you have set

Scenario 2 – Creating Quotes

You want to create Quotes from your Woocommerce orders and send to clients for approval.

  • You create a Woocommerce Order
  • You add all of your products, taxes, shipping, billing details etc
  • You set the Order Status to Quote
  • Sliced Invoices creates the Quote in the background
  • You can then send an email (via one of the 2 options above) to the client with the link to view the Quote
  • Client views the Quote, hopefully approves it and then an Invoice is automatically created
  • If you also have the PDF invoices extension installed, a PDF version of the Invoice or Quote will be attached


  1. Upload plugin to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Go to Woocommerce Checkout settings and then to Sliced Invoices to enable and setup


Minimum System Requirements

  • WordPress 4.0 or newer
  • WooCommerce 2.7 or newer
  • Sliced Invoices 3.7 or newer
  • PHP version from 5.5 up to 8.0


  1. Go to WooCommerce / Settings / Payments and click on Sliced Invoices
  2. Ensure that ‘Enable/Disable’ is checked
  3. Configure the rest of the settings as you require and hit Save

Great plugin to add key quote and invoice features for WooCommerce…This was well-suited to a product business (e.g. 2000+ auto parts). Note the Sliced Invoice plugin is required to be used with this plugin. I still need to experiment with payment flow as WooCommerce’s native invoice and payment flow is poor and has issues with permissions (e.g. the Payment link from the order page brings you to a payment page, but customer and I have rarely had luck paying for or an order.). So hopefully the pay with Paypal will work and then Braintree (now owned by Paypal).
