Why is repeating bill transactions not in the standard subscription

Hello and welcome to the Community, timhumberstone68

Recurring transactions (including invoices, bills, and sales receipts) is a feature available in QuickBooks Online Essentials, Plus, and Advanced.

If you're using QuickBooks Simple Start, you can use the copy feature to create a new copy of an existing bill (open the bill and select More > Copy on the toolbar). After copying, you can edit any details (such as the date) and save. 

Alternatively, you can upgrade your QuickBooks Online subscription today to start setting up recurring transactions (you won't lose any data in the process). Get back in touch if you need any further support!
