Product and service deletion - does this affect already created bills or invoices?

sueo

I have a question about products and services.
My office helper has entered many versions of the same product/service because of changes in spelling etc ie port charge and port charges etc etc.
So there are now many listings of the same item.
Can I delete these superfluous items or does this affect the invoice or bill which has already been created - given that they have already been saved ie the invoice or bill.
I would like to get the items more streamlined if possible.

You actually won't be able to delete items if they appear on any of your invoices. If you want to delete the extra ones, you'll have to go exchange them in your past invoices by hand. It's a pain to do, but it's there so past invoices don't get hurt in the process.

Or! You could just put a bunch of ZZZZ at the beginning of items you don't use anymore. The list is alphabetical, so it would dump those items at the bottom of the product list. It'll make your past invoices look a little weird, but won't actually disrupt anything.
