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 * * * ## On this page - [How credits work](#how-credits-work) - [Usage charges](#usage-charges) - [Add-on summary](#add-on-summary) - [URL integration (Google Automated Discount)](#url-integration-google-automated-discount) - [Shared Google prices](#shared-google-prices) - [Trackers](#trackers) - [Server side tracking](#server-side-tracking) - [Data sources](#data-sources) - [Extra feed schedules](#extra-feed-schedules) - [Extra API feed renewals](#extra-api-feed-renewals) - [Using the Subscription page](#using-the-subscription-page) - [Approval and troubleshooting](#approval-and-troubleshooting) - [Related articles](#related-articles) * * * ## How credits work

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 any allowance. These are applied after dedicated free credits, in add-on order: GAD → Trackers → Server side tracking → Data sources.

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. * * * ## Usage charges 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.

* * * ## URL integration (Google Automated Discount) 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](#shared-google-prices). **Basic setup** 1. Open **Settings → Google** in the app. 2. Follow the setup steps to enable Google Automated Discount on your store. 3. If prompted, approve the subscription update in Shopify (credits and usage charge). **More help:** [Google Automated Discounts (full guide)](https://docs.woolytech.com/en/articles/193-google-automated-discounts.md) * * * ## Shared Google prices 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** 1. Open **Settings → Google** in the app. 2. In **Shared Google prices**, click **Activate** and approve the subscription update in Shopify (credits, and the current Automated discounts usage terms if asked). 3. 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. * * * ## Trackers Install and manage conversion tracking tags (Google Ads, GA4, and other types) in your web GTM container. **Credits and usage** - Credits depend on **tracker type** and how many trackers you install. - **No usage charge** for trackers. - By default, shops receive **10 dedicated free credits for Trackers** (applied only to tracker usage, not other add-ons). - Purchased credits cover tracker usage above your free allowance. **Basic setup** 1. Open **Pixel and Tracking → Client side tracking**. 2. Add or edit trackers in your GTM container. 3. Ensure your subscription includes enough **purchased credits** on the Subscription page. **More help:** [Google Ads tracking tags (full guide)](https://docs.woolytech.com/en/articles/194-google-ads-tracking-tags.md) * * * ## Server side tracking Send events through a server-side Google Tag Manager container for more reliable tracking. **Credits and usage** - Uses **5 purchased credits** when a **server GTM container** is configured for your shop. - Included with those credits: **500,000 server-side tracking requests** per credit term. - Usage beyond the included volume is billed at **$1 per 100,000 requests** (Server side tracking usage). - May be available only on **eligible shops** (limited rollout). **Basic setup** 1. Open **Pixel and Tracking → Server side tracking**. 2. Complete server container setup (sGTM). 3. Approve subscription changes if you are asked for credits or usage charges. **More help:** - [Server side tracking (full guide)](https://docs.woolytech.com/en/articles/238-server-side-tracking.md) - [Server side tracking benefits](https://docs.woolytech.com/en/articles/218-server-side-tracking-benefits.md) * * * ## Data sources Create reusable data sources for lookup expressions in your feeds. **Credits and usage** - **1 credit per data source** in use. - **No usage charge** for data sources. **Basic setup** 1. Open **Settings → Data sources**. 2. Create or import data sources as needed. 3. Reference them in feed rules and lookups. **More help:** [Data source lookup](https://docs.woolytech.com/en/articles/data-source-lookup.md) * * * ## Extra feed schedules Run file-based feeds more than once per day with additional scheduled refresh times. **Credits and usage** - **No credits** — this add-on is **usage-only**. - Billed when you have **more than one** daily file-feed refresh schedule. - Requires a **paid base plan** (at least the **1,000 product** tier, e.g. MultiFeed-1K). Usage charges cannot be added to a $0 free base plan alone. - **Extra refreshes** usage: **$0.03 per 1,000 feed products** per extra scheduled run. **Basic setup** 1. Open **Settings → Schedules**. 2. Add an additional daily refresh time (more than one schedule). 3. Approve the Shopify subscription update to add the **Extra refreshes** usage line if prompted. * * * ## Extra API feed renewals Renew API feed item expiration more frequently than the default 30-day cycle. **Credits and usage** - **No credits** — this add-on is **usage-only**. - Active when API feed renewal frequency is **more than once per 30 days** (configured on the Schedules page). - Same **paid base plan** requirement as extra feed schedules. - **Extra renewals** usage: **$0.30 per 1,000 feed products** per extra renewal cycle (30-day basis). **Basic setup** 1. Open **Settings → Schedules**. 2. Set **API feed renewals** to a shorter interval (for example, 15 days, 7 days, or 1 day). 3. Approve the Shopify subscription update to add the **Extra renewals** usage line if prompted. * * * ## Using the Subscription page 1. Open **Subscription** from the app navigation. 2. Review **Plan** — base plan name, price, and purchased credits (including Missing/Surplus status when you change credits in the form). 3. Review **Credit usage** — per-feature breakdown and totals at the end of each bar. 4. Under **Subscription options**: - Change **Base plan** tier if needed. - Set **Credits** (minimum reflects current usage minus eligible free credits). - Optionally apply a **Coupon**. - In **Add-ons**, each row shows: - A checkmark when the add-on is **in use**, or an empty circle when not - **Learn more** — opens this guide at the section for that add-on - **Configure** — opens in-app settings for that add-on 5. Click **Update subscription** and complete Shopify’s approval for plan, credit, or usage changes. * * * ## Approval and troubleshooting **When activating an add-on**, Shopify may show: - **Plan upgrade** — if you are on a free base plan and the add-on requires a paid plan (common for extra schedules and renewals). - **Usage charge approval** — terms for the relevant usage line. - **Credits to purchase** — how many purchased credits you need to add. **Common issues**

Symptom

What to check

Add-on shows “not in use” but you enabled billing

Finish in-app setup (e.g. SST needs a server container; GAD needs Settings → Google).

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.
