I just buy your Software Web in year, so I need an invoice for my company.

Welcome to the Community family, Sophany. I'm here to help you with your inquiry about QuickBooks Online (QBO) invoices. 
 

If you're referring to your invoice for your QBO subscription, the invoice will be sent monthly to the email address you provided when signing up. When you receive the email, click on the View Billing History to see all your invoices, from where you can download a PDF copy if you need to.

On the other hand, If you're looking to create an invoice for your business, here's how:
 

1. Click the + New button and select Invoice.
2. Choose a customer from the Add customer drop-down.
3. Enter the date or terms if needed.
4. Select a product or service from the Product/service drop-down.
5. Fill in the fields for Description, Qty, Rate, and Amount.
6. Once done, click Save and close. 

Additionally, if you wish to view your payment history, update or change your payment method, and change your billing schedule, check out this help article: Manage billing, payment, and subscription info in QuickBooks Online. 
 

If you have further questions or concerns about receiving your invoices from your billing subscription or managing your invoices in QBO, you can always count on us. We're always here to help. Have a good one.
