Welcome to the Community, @edesvaux.
To make sure you're able to get the invoice for your QuickBooks Online Plus subscription, I'd suggest you contact the QuickBooks Online Customer Support team.
They have additional tools to pull up your billing records and can send you the details of the invoice through email.
Here's a link that can help you find answers and guide you in case you'll need some easy steps for your How do I tasks?.
Please know I'm always available here to lend a helping hand. Have a great day ahead.
