In 2026 Shopify changed how some in-progress inventory holds are categorized: stock held by active draft orders, open transfers and shipments moves from the reserved quantity state to committed. The change does not reduce available or on-hand inventory and does not make extra units sellable; it changes which unavailable bucket reports the hold.
This matters most when a store, custom report or app used reserved inventory as a shortcut for “stock held by draft orders or transfers.” After the migration, that assumption can produce unexpectedly low reserved figures while committed rises by a similar amount.
What Shopify moved from reserved to committed
Shopify is consolidating active draft-order holds and open transfer or shipment holds into the committed quantity state. Committed already represents inventory spoken for by orders but not yet fulfilled, so the change puts more types of in-progress allocation into one state.
The migration applies to active records still holding inventory when the change runs. Completed, cancelled or released holds do not need to be moved because they no longer tie up stock.
What does not change
Shopify states that available and on-hand quantities are unaffected. Total physical inventory is not being adjusted. A quantity moves between reserved and committed, both of which represent stock that is not currently available for ordinary sale.
That distinction is important during reconciliation. Seeing a drop in reserved does not automatically mean units returned to sale, and seeing committed rise does not automatically mean new customer orders appeared.
Why reports can look different after the migration
Inventory adjustment reports can show a one-time correction when active holds are reclassified. Historical data before the migration remains as it was, so a chart may show a discontinuity even though the warehouse did not receive or lose stock.
When comparing periods, annotate the migration date. Otherwise an analyst may interpret the state change as an operational improvement or deterioration rather than a reporting taxonomy change.
Which custom apps and automations need attention
An integration that requests only the reserved quantity name and treats it as all non-sellable draft or transfer stock may now miss those holds. Shopify recommends reading committed for affected use cases going forward.
Both reserved and committed remain valid queryable names, so this is not a field-removal problem. It is a meaning-of-the-number problem. Audit business logic, alerts and dashboards that depend on a specific inventory state.
A simple merchant example
Assume a location has 20 units on hand. Five are already unavailable because they are held for an active draft order. Before the migration, an internal report may show those five under reserved. After the migration, the same five can appear under committed.
If available and on-hand remain unchanged, the store has not gained or lost five units. Only the classification of the hold has changed.
How to reconcile a suspicious inventory difference
First compare on-hand and available, not just reserved. Then inspect active draft orders, transfers and shipments. If the difference corresponds to those holds, check whether the reporting window crosses Shopify’s migration.
If available inventory itself changed unexpectedly, investigate actual adjustments, fulfillments, cancellations, receiving events and app activity. The reserved-to-committed migration is not an explanation for a genuine available-stock loss.
What to document for staff
Update internal definitions so staff know that committed can now include more than standard customer orders. If your warehouse or support team uses screenshots from inventory reports, add a short definition next to each state.
For stores with custom ERP or WMS connections, ask the integration owner to confirm which Shopify quantity names are consumed and whether the business logic was updated for the 2026 change.

Frequently asked questions
Did Shopify remove the reserved inventory state?
No. Reserved and committed both remain valid quantity names.
Does the migration change how many units customers can buy?
Shopify says available inventory is unaffected, so the migration itself does not change sellable quantity.
Why did committed inventory suddenly increase?
Active draft-order, transfer and shipment holds may have been reclassified from reserved to committed.
Do historical reports get rewritten?
Shopify says historical data before the migration remains as-is, while reports may show a one-time correction for active holds that moved states.
