Invoice number CHANGED after marking the payment as Completed

Hi @innovachievers,

By default, WooCommerce doesn’t have any PDF invoice feature. The issue you’re experiencing might be due to the PDF Invoice plugin you are using. It may be updating the invoice numbers based on the year.

Since this is a third-party plugin which we don’t provide support for (please see our Support Policy), it would be best to reach out to the plugin’s developers for further assistance.

I am sure they will have no problem supporting you there.

Thanks!

Hi, I wrote to the Plugin support and they said to write here.
I write here and you say to write to the Plugin support.

In the end here I am not asking for a plugin support, I am asking something about the core WooCommerce functionality:
1) How to avoid sending an email confirmation to the client when the I mark the invoice as paid;
2) How to manually change the invoice number in the Order section.

Thank you!

Hi @innovachievers!

Thank you for reaching out to us back; I will gladly help you.

Before we go further, it is important to clarify one thing:

As my colleague mentioned in an earlier reply, WooCommerce Core does not have a built-in invoicing feature that generates formal invoices for customers.

WooCommerce processes orders and provides basic order details like order confirmation and receipts that can be viewed from the customer account page or sent as emails, but these are not typically considered full invoices by accounting standards.

However, to generate invoices in WooCommerce, store owners typically use additional plugins that extend WooCommerce’s functionality (like you are doing).

With that in mind, let’s dive in:

1) How to avoid sending an email confirmation to the client when the I mark the invoice as paid

If you mean to avoid sending an email confirmation after a complete order, you can change this in WooCommerce > Settings > Emails, look for the Completed order option and click Manage. Once in there, unselect the Enable this email notification option, and you are good to go. 

Check more about email notifications here: https://woo.com/document/configuring-woocommerce-settings/#email-settings

If you meant to avoid sending an email confirmation after you mark an invoice as paid, there is no option in WooCommerce core to do that.

2) How to manually change the invoice number in the Order section.

If you want to change the order number of an order, kindly note that it is not possible with WooCommerce core features; you would need to use a plugin for that, like Custom Order Number.

If you meant you want to change the invoice number of an order in the Order section, as mentioned, WooCommerce core doesn’t have an invoice feature, so the invoice number you see in the Order section must be placed by a plugin you are using.

In this case, we recommend you reach out to the plugin support for further assistance on this.

If you want, I can try pointing you to the right support team for your invoicing plugin; for that, kindly send us your system status report: you can find it via WooCommerce > Status. Select ‘Get system report’ and then ‘Copy for support’. Once you do this, paste your response here.

Cheers!

Thanks @judagutor this is the quality of support I would expect!

I solved part of the problem thanks to your indications (and the other part by reading long and large the cryptic documentation of the specific plugin).

Cheers!

Hi @innovachievers,
