How Shopify Handles App Billing
Notify Me is a third-party Shopify app. All charges, including your monthly subscription and any usage-based fees, are processed through Shopify’s billing system.
These charges appear in your Shopify invoice under the App charges or Transaction fees section. For more on how Shopify handles app billing, visit: Shopify Help Center – App charges
When You’ll See Charges from Notify Me
Shopify bills merchants on a fixed billing schedule based on when your store first subscribed to Shopify.
Notify Me charges, including your subscription and any additional usage fees, are added to your Shopify invoice during that billing cycle. Notify Me does not issue separate invoices. All charges are included in your Shopify billing.
Example
Your Shopify billing cycle runs from June 8 to July 7 (based on when you first subscribed to Shopify)
You upgraded to a paid Notify Me plan on June 12
You’re on the Pro plan ($39.90/month), which includes:
50 notifications
100 wishlist actions
Extra usage is charged at:
$0.25 per additional notification
$0.10 per additional wishlist action
You also use SMS and PreOrder
Notify Me tracks your usage and charges starting from June 12, the day you began your paid plan.
What you see in Notify Me!
Between June 12 and July 11, you:
Sent 90 notifications → 40 over your plan → $10.00
Logged 160 wishlist actions → 60 over your plan → $6.00
Incurred $24.00 in SMS charges
Incurred $12.00 in PreOrder charges
In your Notify Me dashboard, under Add-on Charges, you’ll see:
$16.00 from extra usage
$36.00 from SMS and PreOrder
Total displayed: $52.00
What you see in Shopify billing
Your Shopify invoice is generated on July 8. Shopify will include:
$39.90 for your Notify Me subscription
Extra usage between June 12 and July 7 (since you weren’t on a paid Notify Me plan before June 12):
30 additional notifications → $7.50
45 additional wishlist actions → $4.50
$18.00 in SMS charges for that period
$9.00 in PreOrder charges
Some of your usage was between July 8 and July 12, which is after Shopify’s billing period and will appear on your next Shopify invoice. That’s why in this example, the usage charges shown in Shopify are lower than what you see in your Notify Me dashboard.
Total on your Shopify invoice for Notify Me:
$39.90 (base plan)
$12.00 (extra usage)
$27.00 (SMS and PreOrder)
= $78.90
All of these charges appear under Transaction fees in your Shopify invoice.
