Step 3:

Locate and click cart.liquid right under the Templates folder to open it in the online code editor.

Step 4:

Add the code given below at the bottom of the cart.liquid:

<script>
jQuery('[max]').change(function() {
  var max = parseInt(jQuery(this).attr('max'), 10) || 10000;
  var value = parseInt(jQuery(this).val(), 10) || 0;
  if (value > max) { jQuery(this).val(max); }
});
</script>

Step 5:

Place the code given below in the same file:


value="{{ item.quantity }}"

Step 6:

Add the code given below after value="":


{% unless item.variant.inventory_management == blank or item.variant.inventory_policy == 'continue' %} max="{{ item.variant.inventory_quantity }}" {% endunless %}

It should look similar to this in the end:


<input type="text" ... name="updates[]" id="updates_{{ item.id }}" value="{{ item.quantity }}" {% unless item.variant.inventory_management == blank or item.variant.inventory_policy == 'continue' %} max="{{ item.variant.inventory_quantity }}" {% endunless %} />

Step 7:

Tap Save to save all changes to your file.

Conclusion

By following these steps, you can ensure that your Shopify cart page automatically updates quantities to match available stock without confusing your customers. This silent correction helps prevent over-purchases and enhances the overall shopping experience. Implementing this solution not only streamlines your cart management but also maintains customer satisfaction by providing a seamless checkout process.
