I cannot add more products to the preorder list

All plansLast verified 11 November 2026View as Markdown

EZ Preorder & Back In Stock stops you adding products to the preorder list for one of four reasons: your store reached the Free plan's lifetime limit of 10 preorders or $400, your store is on the older free plan that allows one product, you are trying to use Bulk actions on the Free plan (they need Core or higher), or your preorder list is very large. The app's own guidance is that the preorder list cannot support more than 600 products at once, and fewer when products have many variants.

Available on: All plans. Bulk actions need the Core plan or higher.
Where to find it: EZ Preorder → Preorders.

The Select products button is greyed out on the Free plan

On the Free plan, EZ Preorder greys out Select products once your store reaches the Free plan's lifetime limit: 10 preorders or $400 in preorder revenue, whichever comes first. At the same moment every product on your preorder list is turned off, and the Preorders page shows a window titled You have reached your plans preorder limit with the message "All preorders are currently disabled. Upgrade your plan to continue accepting pre-orders."

To add products and take preorders again:

  1. Click GO TO PLAN in the window, or open Plan in the app menu.
  2. Choose Core, Growth, Professional or Scale.
  3. Back on Preorders, turn your products back on. They are not turned on automatically after you upgrade.

See Plan limits and How to change or cancel your plan.

The product picker says you can only add one product

Some stores are still on an older free plan that allows one product on the preorder list. On that plan the Select products window shows the banner "You are on the free plan. You can only add one product to the preorder list. Please upgrade your plan to add more than one product." Once one product is on the list, the other checkboxes are greyed out and Select products is greyed out on the Preorders page. Click Upgrade now in the banner, or open Plan, to move to a current plan.

Bulk actions is greyed out

Bulk actions on the EZ Preorder Preorders page holds Bulk Add, Bulk Add Collections, Bulk Settings and Bulk Remove. It is available on Core, Growth, Professional and Scale. On the Free plan the button is greyed out, and hovering over it shows "Available on Core plan or higher". On the Free plan, add products one at a time with Select products. See Plans and pricing.

Your preorder list is very large

EZ Preorder stores your whole preorder list together and loads all of it each time you open the Preorders page. The Bulk Add window states that the app "cannot support over 600 products on the preorder list at once". There is no fixed cutoff in the app: every variant on the list is stored too, so a list of products with many variants reaches the practical limit with fewer than 600 products.

If adding products fails or the list stops loading properly:

  1. Remove products you no longer sell on preorder. See How to remove a product from preorder.
  2. Add only the variants you need. In Select products, click a product to expand it and tick individual variants instead of the whole product.
  3. Clear out deleted variants. Click Sync all on the Preorders page to remove variants you deleted in Shopify. See The product on my preorder list does not match Shopify.
  4. Contact support if you need more products on preorder than the list can hold.

Adding many products at once does not finish

When you add a large number of products in one go, EZ Preorder sends them all in a single save. A very large save can fail or never finish. Add products in smaller batches instead:

  • In Select products, tick a few dozen products at a time and click Save after each batch.
  • Use Bulk Add Collections to add one collection at a time rather than Bulk Add.
  • Avoid Bulk Add on large catalogs. It adds every product with the status Active in your store, all in one save.

An error message from a failed save ends with "- Click to upgrade" whatever the cause, so it does not always mean your plan is the problem.

Frequently asked questions

How many products can I add to the EZ Preorder list?

There is no fixed number. The app's guidance is up to 600 products, and fewer if your products have many variants. On the Free plan you can add products until your store reaches 10 preorders or $400 in preorder revenue.

Why is Select products greyed out?

On the Free plan, your store has reached the lifetime limit of 10 preorders or $400 in preorder revenue. On the older one-product free plan, one product is already on the list. Upgrade on the Plan page to add more.

Does Bulk Add include draft or archived products?

No. Bulk Add adds every Active product in your store. To add a draft product, use Select products.

Do I need to remove a product before adding it again?

No. If a product is already on the list, ticking more of its variants in Select products adds just those variants.

Does upgrading turn my preorders back on?

No. When a plan limit turns your preorders off, they stay off after you upgrade until you turn them on again on the Preorders page.
