Sales receipts, can they be personalised like the invoice such as adding logos, also can the drop down options for payments be edited... such as ‘bank transfer’?

Hello there, clanrobbo. Yes, the sales receipt can be personalised too!

Let me guide you on how to do it. Here's how:

1. Go to the Gear icon.
2. Select Custom Form Styles under Your Company.
3. Click the New style drop-down arrow. 
4. Select receipts.
5. We can modify the form anytime by going back to this page. Then, click Edit under the Action column.

Here are the articles that will surely help us in making the things we want for the form such as adding logos on it: 

• Customise invoices, estimates, and sales receipts in QuickBooks Online.
• Email and customise sales forms.

About editing payments for the transaction, yes we can edit it by clicking the drop-down arrow and select the bank where you want to deposit it.

I'm always here to help. Just let me know anytime. Stay healthy. Take care!
