Watches every fixed bundle's components and warns you the moment one becomes unfulfillable.
A fixed bundle is only as available as its scarcest component, but a component that is untracked, or set to keep selling when out of stock, does not reduce what the bundle appears to have. Third-party bundle syncs can also drift from the component stock they were built on. The result is a bundle that sells and then cannot be assembled — a refund, an apology, or a scramble to a supplier. BundleGuard reads each bundle's components and reports how many you can genuinely build right now.
BundleGuard reads products, variants, inventory levels and, for forecasting, the variant IDs and quantities on your last 30 days of orders. It stores no customer names, emails or addresses. It makes no theme changes and adds no tags; the only write it ever makes is the Active/Draft status of a bundle you switched Auto-protect on for.
Free plan: the three bundles most at risk, with buildable stock and forecasts. Standard is $9.99 per month, or $99.90 per year, with a 14-day free trial, billed through Shopify: every bundle, Auto-protect, email, Slack and Flow alerts, and the weekly summary. Cancel from your Shopify admin at any time.
What does "buildable" mean?
The number of bundles you could assemble from current component stock: for each component, available quantity divided by the quantity the bundle needs, and the lowest result wins.
Which bundles are covered?
Fixed bundles that expose their components through Shopify's bundle data, plus any kit you add yourself with Add a bundle.
Why is a bundle healthy in Shopify but at risk here?
Shopify's bundle availability ignores untracked and continue-selling components. BundleGuard counts them as risks because they let the bundle sell with no stock behind it.
How does the forecast work?
With access to your order history, BundleGuard measures how fast each bundle and component sold over the last 30 days and shows, per bundle, roughly how many days until it runs out, which component is the bottleneck, and how many units of it to order to cover the next 30 days. Bundles running out within a week are flagged as warnings.
Does the app change inventory or products?
Only if you ask it to. With Auto-protect off, which is the default, it reads bundles, products, inventory levels and order line items and writes nothing. With Auto-protect on for a bundle, the one thing it changes is that product's Active/Draft status. It never changes inventory quantities and never reads customer names, emails or addresses.
What is the price?
The Free plan covers the three bundles most at risk, with buildable stock and forecasts. Standard is $9.99 per month, or $99.90 per year, with a 14-day free trial, billed through Shopify: every bundle, Auto-protect, email, Slack and Flow alerts, and the weekly summary.
