Defining a bill or invoice using Google email markup - email

Question

I know this can be done because i'm looking at an invoice from a telco in my gmail inbox mobile app but I don't know how to set the gmail markup / schema to make it happen.
The example I have shows:
August bill for xxxx
Total: $xxx, due MMM DD
$ Total amount due
$xxxx
Due date
DD MMM
Issuer
Telco X
Can anyone help?
I can't find any guidance on the email markup pages on Google.

Answer 1

It uses regular http://schema.org markup within the HTML of the email. See gmail markup reference.
Example adapted from google's gmail markup example:
<div itemscope itemtype="http://schema.org/Order">
<div itemprop="merchant" itemscope itemtype="http://schema.org/Organization">
<meta itemprop="name" content="Amazon.com"/>
</div>
<meta itemprop="orderNumber" content="123-4567890-1234567"/>
<meta itemprop="priceCurrency" content="USD"/>
<meta itemprop="price" content="259.99"/>
<div itemprop="acceptedOffer" itemscope itemtype="http://schema.org/Offer">
<div itemprop="itemOffered" itemscope itemtype="http://schema.org/Product">
<meta itemprop="name" content="Samsung Chromebook"/>
<meta itemprop="sku" content="B009LL9VDG"/>
<link itemprop="url" href="https://rads.stackoverflow.com/amzn/click/com/B009LL9VDG" rel="nofollow noreferrer"/>
<link itemprop="image" href="http://ecx.images-amazon.com/images/I/81H-DO3qX0L._SX522_.jpg"/>
</div>
<meta itemprop="price" content="249.99"/>
<meta itemprop="priceCurrency" content="USD"/>
<div itemprop="eligibleQuantity" itemscope itemtype="http://schema.org/QuantitativeValue">
<meta itemprop="value" content="1"/>
</div>
<div itemprop="seller" itemscope itemtype="http://schema.org/Organization">
<meta itemprop="name" content="Samsung Marketplace Store"/>
</div>
</div>
</div>
<div itemprop="priceSpecification" itemscope itemtype="http://schema.org/DeliveryChargeSpecification">
<meta itemprop="price" content="10.00"/>
<meta itemprop="priceCurrency" content="USD"/>
</div>
<link itemprop="url" href="https://www.amazon.ca/gp/css/summary/edit.html/orderID=123-4567890-1234567"/>
<div itemprop="potentialAction" itemscope itemtype="http://schema.org/ViewAction">
<link itemprop="target" href="https://www.amazon.ca/gp/css/summary/edit.html/orderID=123-4567890-1234567"/>
</div>
<link itemprop="orderStatus" href="http://schema.org/OrderStatus/OrderProcessing"/>

#AaronP, I've posted my findings and example in this issue similar to your question. Using schema.org/Invoice and schema.org/PayAction, I was able to get the email similar to what you received from Telco X. Keep in mind that this seems only active with Inbox and not Gmail.
<script type="application/ld+json">
[
{
"#context": "http://schema.org",
"#type": "Invoice",
"description": "January 2015 Acme Bill",
"url": "https://www.americanexpress.com",
"accountId": "xxxx-xxxx-xxxx-1234",
"potentialaction": {
"url": "https://example.com",
"#type": "PayAction"
},
"paymentDue": "2020-01-30",
"minimumPaymentDue": {
"#type": "PriceSpecification",
"price": "$15.00"
},
"totalPaymentDue": {
"#type": "PriceSpecification",
"price": "$200.00"
},
"paymentStatus": "payment due",
"provider": {
"#type": "Organization",
"name": "Acme Bank"
}
}
]
</script>
You should get this:
