Add-ons extend your base plan (product, variant, and feed limits). Most add-ons use monthly purchased credits on your subscription. Some add-ons also include usage charges on your Shopify bill when you go beyond the volumes included with your credits.
Manage everything from Subscription in the app:
Plan — your base plan and purchased credits status
Credit usage — a chart showing how credits are used per add-on
Subscription options — change plan tier, purchased credits, and view the Add-ons list
Concept | What it means |
|---|---|
Purchased credits | Credits you buy through your subscription. Set them under Subscription → Credits. They must cover your total add-on usage, or you may see a deficit on the credit usage chart. |
Dedicated free credits | Free credits tied to a specific add-on in your shop policy. By default, new shops receive 10 free credits for Trackers only (not a shared pool for all features). |
Shared “any” credits | Only if your shop or coupon policy defines a global |
Credit usage chart | Per add-on bars showing: free credits used (green), purchased credits used (blue), unused dedicated bonus (hatched gray), and deficit (hatched red) when purchased credits are not enough. |
Minimum credits | The subscription form enforces a minimum number of purchased credits based on your current usage minus eligible free credits. |
Good to know
Billing “on” vs actually in use: Approving an add-on in Shopify does not always mean it is fully configured. The add-ons checklist and credit chart reflect real usage (for example, Server side tracking requires a server GTM container).
Trackers: Credit cost depends on tracker type. Your first GA4 tracker may qualify for a one-time free-credit discount.
Purchased vs free “any”: Only credits listed under any in your policy are shared across features. Default shops do not get 10 generic “any” credits—the default is 10 dedicated tag (Tracker) credits only.
Some add-ons include a usage allowance with your credits. If you exceed that allowance, Shopify bills usage charges (shown on the subscription approval screen and on your app bill). Each usage line has a monthly cap where noted.
Service (on Shopify bill) | Rate | Add-on |
|---|---|---|
Automated discounts usage | $1 per 1,000 Google Automated Discount offers (discount codes, signed offers or shared price updates) | URL integration (GAD), Shared Google prices |
Server side tracking usage | $1 per 100,000 server-side tracking requests | Server side tracking |
Extra refreshes | $0.03 per 1,000 feed products per extra scheduled file-feed run | Extra feed schedules |
Extra renewals | $0.30 per 1,000 feed products per extra renewal cycle (30-day basis) | Extra API feed renewals |
Usage lines are typically capped at $300 per month per line item.

Let Google show optimized prices on your Shopping ads and on product landing pages.
Credits and usage
Uses 5 purchased credits while the feature is active.
Included with those credits: 5,000 offers per billing period. An offer is the discount code or signed price created for a shopper's Google ad click; a shopper coming back to the same offer is not counted again.
Usage beyond the included offers is billed at $1 per 1,000 offers (Automated discounts usage).
Need the Google price to reach more shoppers or variants? See Shared Google prices.
Basic setup
Open Settings → Google in the app.
Follow the setup steps to enable Google Automated Discount on your store.
If prompted, approve the subscription update in Shopify (credits and usage charge).

An extension of URL integration (GAD): show the Google price from an ad click to more shoppers and more variants, so a good price reaches everyone who is likely to buy.
Options
Show Google price to all shoppers: the latest Google price of a variant shows to anyone who opens the product page, on any device, not only to the shopper who clicked the ad. It lasts until the price ends (Google price duration).
Apply to all variants with the same price: other variants of the product with the same price as the clicked variant get the Google price too (for example other sizes of a T-shirt). It works for the shopper who clicked the ad, and for all shoppers when the first option is on. Needs the shared automatic discount: activating the add-on switches your store to it.
Credits and usage
Requires URL integration (GAD) to be active.
Uses 5 purchased credits while the add-on is active.
Each shared price update counts as one GAD offer: an update happens when the Google price shown to all shoppers is set for a variant, or changes. It uses the same 5,000 included offers and the same $1 per 1,000 offers as GAD, so for most stores sharing adds nothing to the bill.
Sharing between variants creates no updates and is not counted.
Example: with a 48-hour Google price duration, a variant clicked every day makes about 15 updates a month, plus one each time Google changes its price.
Basic setup
Open Settings → Google in the app.
In Shared Google prices, click Activate and approve the subscription update in Shopify (credits, and the current Automated discounts usage terms if asked).
Turn on Show Google price to all shoppers, Apply to all variants with the same price, or both, then save.
Where to see usage: Subscription → Add-ons usage charge → URL integration (Google Automated Discount) shows your offers, including shared price updates, the billable offers and their amount. Settings → Google → Performance shows shared price updates over time.

Red deficit on the credit chart | Increase Purchased credits on Subscription to cover usage. |
Subscription update fails on a free plan with feed add-ons | Upgrade base plan to at least 1,000 products before adding extra refresh or renewal usage. |
