Hello, @sbajimaya. I've got a workaround for you to repeat the header with a logo and add customer details to your invoice. 

Repeating header with logo and customer details to your invoice in multiple pages is currently unavailable in QuickBooks Online (QBO). As a workaround, you may consider downloading your invoices. Then, manually add the header, logo, and customer details to your spreadsheet according to your preferred setup. 
 

Additionally, you can check this article for complete guidance on how you can record sales transactions efficiently in QuickBooks: Record invoice payments in QuickBooks Online. 

Please let us know if you have further questions or concerns with your invoices or any other QBO products. We're always here to help. Have a good one.
