In HostShop you can send your customers Custom Work Quotes for 'one-off' payments or quotes for services you’re providing. They might be used for services that you don't want as a selectable product in your shop, but you do want your customer to make payment for using HostShop.
You can add a Custom Work Quote for an individual StackCP User by going to:
StackCP Users > Options > Manage > Custom Work Quotes
1) Fill out the information requested and select Create Draft. The expiry date is the date at which the custom work quote will no longer be able to be purchased by the StackCP User.
2) Once you've created the draft quote, you'll be able to select Options > Edit. From here you then select Send Quote. This will send the quote to the StackCP User's email address. They'll then be able to select View Quote and Checkout directly from the email which will take them to their control panel.
The email that is sent is the email template called: HostShop: 'Custom Work Quote - customer'. This can be modified in Email Templates.
