Your plan's stock syncing comes with a monthly limit. The limit counts orders, not single stock updates. This article explains what counts, what happens as you get close to the limit, and how to check your usage.
Which plans include stock syncing
Growth: up to 200 orders per month
Scale: up to 1,000 orders per month
Max: no limit
The Essential plan does not include stock syncing. See Shuttle's Available Plans for everything each plan includes.
Which orders count
Shuttle counts orders from both of your shops. An order counts toward your limit when all of these are true:
The order is paid.
At least one item in the order is a matched product, meaning it is linked between Shopify and Etsy.
That matched product is not excluded. See Excluding products from updates and transfers.
If Exclude digital products is on, the item is not digital. For Shopify orders, this means the item needs shipping. See Excluding Digital Products from Stock Syncing.
For Shopify orders, Shopify tracks the item's inventory.
A few more things to know:
Etsy orders count only while syncing from Etsy to Shopify is turned on. Shopify orders count only while syncing from Shopify to Etsy is turned on.
If Shuttle transferred an Etsy order into Shopify, it counts once, not twice.
If Update all duplicate SKUs is on, an order can also count when one of its items shares a SKU with a product in Shuttle that is not excluded, even if that item is not matched itself. See Syncing Quantity Updates for Duplicate SKUs.
Orders that don't meet these rules never count.
The 20% grace period
On Growth and Scale, stock syncing keeps running for 20% beyond your limit:
Growth: the limit is 200 orders, and syncing continues up to 240 orders
Scale: the limit is 1,000 orders, and syncing continues up to 1,200 orders
What happens at each stage
Under your limit
Stock syncs as normal.
At 80% of your limit, you get an email letting you know you're getting close.
At your limit
Stock keeps syncing.
You get an email saying you've reached your limit and the grace period has started.
The Stock Syncer page shows an At limit badge.
In the grace period (up to 20% over)
Stock keeps syncing.
The Stock Syncer page shows a Grace badge.
More than 20% over
Stock syncing pauses in both directions until your limit resets or you upgrade.
You get an email saying stock syncing has been paused, with the date it resets.
The Stock Syncer page shows a Quota reached badge, and both syncing directions show Limited.
Each of these emails is sent at most once every 7 days.
What keeps working when syncing is paused
Only stock syncing between your shops pauses. Product transfers, order transfers, fulfillment and reviews keep working as usual.
When the limit resets
Your order count resets on the first day of every calendar month. It does not follow your billing date. The Stock Syncer page shows the reset date.
Checking your usage
Open Stock Syncer in Shuttle.
Find Sync Quota at the top of the page.
You'll see the orders counted this month, your monthly limit, and the date it resets. A badge shows when you're at your limit, in the grace period, or paused.
Frequently asked questions
Do stock changes I make myself count?
No. Only orders count. Stock changes you make in Shopify or Etsy, and updates you run with Shuttle's own tools, never add to your count.
What about orders with only unmatched products?
They don't count. The one exception is when Update all duplicate SKUs is on and an item shares a SKU with a product in Shuttle, as explained above.
How can I stay under my limit?
Exclude products you don't need synced.
Turn on Exclude digital products if you sell digital items that don't need stock syncing.
Check Sync Quota on the Stock Syncer page from time to time.
Need a higher limit?
Growth to Scale: 1,000 orders a month instead of 200.
Scale to Max: no limit.
To upgrade, go to Settings, then Account, then Plan, and select Change plan. You'll approve the change in Shopify. Your new limit applies as soon as the new plan is active, so a paused sync can start again before the month ends. See Upgrading & Downgrading Plans.
