Thanks for joining us here today, @MelissaFITCO.
I'll share some information about editing invoice templates. In QuickBooks, if you're editing company info (company email), it'll also update your other invoice templates.
If you want to create separate invoice templates, you can use the import custom form style as mentioned by my peer @Catherine_B. Please refer to the above steps on how to enable this feature.
You can also check out this guide for the step-by-step instruction: Import custom form styles for invoices or estimates.
With import custom styles, you're now able to design custom invoice styles and use different invoice templates for your customers.
Additionally, here's a link that'll help you manage customer-related tasks. It contains topics about your company's income and customers. Just choose a title that'll fit your concern: Sales and customers.
Should you have other invoice questions? Drop them below and I'll be happy to answer them for you. Take care and have a wonderful day ahead.
