Hello @diamondcutlawnan,
It's nice to see you in the Community. I'm here to lend a hand with changing the amount to charge for a product/service.
You can change the default amount to charge within the list of Products and Services. Here's how:
- Select the Gear icon.
- Click Products and Services.
- Select Edit in the Action column for the product/service that you want to change.
- Enter the new amount to charge within the Sales price/rate field.
- Click Save and close.
I've included a brief video to serve as a visual reference:

The following article contains additional information about this: Add Product Information.
You'll soon be an expert at changing your products and services, I have no doubt.
Don't hesitate to post a comment below should you need anything else, as I'd be happy to continue helping. Have a lovely weekend.
