Is it possible to add my company details on the statement, before sending it to my customers?
Nice to see you here, @sales271. I'll be sharing additional information with customising statements in QuickBooks Online.
In QuickBooks Online, if you send a statement to your customer, the company details are already included by default. However, the option to customise the statement template is unavailable. You can only customise the list of each transaction as a single line, including all details, and show the aging table at the bottom of the form.
