Unfulfilled vs Partially Fulfilled vs Fulfilled: When to Split
Quick answer: Unfulfilled means none of the items in an order have shipped. Partially fulfilled means at least one item has shipped and at least one hasn't. Fulfilled means every item has shipped. The first and the last are simply stages. Partially fulfilled is the one that needs a decision, because something held back part of the order: a stock-out, an item stored in another location, a pre-order, or a unit that failed inspection. Choose between shipping what's ready now and holding everything for one parcel by weighing three things: how long the gap is, what a second parcel costs, and what the customer was promised.
The three statuses side by side
| Unfulfilled | Partially fulfilled | Fulfilled | |
|---|---|---|---|
| Items shipped | None | Some | All |
| Tracking numbers | None yet | One per shipment sent so far | One per shipment, usually just one |
| What the customer has had | An order confirmation | A shipping notice for part of the order | Shipping notice for everything |
| Work still open | The whole order | The missing lines | Only delivery and after-sales |
| When to worry | Older than your processing time | Missing lines have no ship date | Tracking stalls |
Labels differ by platform: Amazon says Partially shipped, BigCommerce Partially Shipped, and WooCommerce leaves the order in Processing unless you use its optional Fulfillments feature. Our fulfillment status comparison maps each platform's names. For all the other Shopify badges, see Shopify order status explained.
Six ways an order ends up partially fulfilled
- A stock-out. One item ran out between the sale and the packing. This is the most common cause in dropshipping, where the supplier's stock, not yours, is what counts.
- Stock in two places. One item sits in an overseas warehouse and the other only in China, so each location ships its own share. Routing rules decide this; see distributed order management.
- Pre-orders and backorders. The customer bought an in-stock item and a pre-order item together.
- Made-to-order or personalized lines. A custom item takes longer than the standard items next to it.
- A failed inspection. A unit was rejected at quality control and the replacement hasn't arrived from the supplier yet.
- Different suppliers, no consolidation. Each supplier ships its own item as soon as it's ready, which splits every multi-item order by default.
The first four happen to every store now and then. The last two are setup choices, and they're fixable.
Ship now or wait? A decision table
| Situation | Usually better | Why |
|---|---|---|
| Missing item arrives in a day or two | Wait and send one parcel | One shipping charge, one tracking number, one delivery |
| Missing item has no restock date | Ship what you have; offer a swap or refund for the rest | A customer with part of the order is happier than one with nothing |
| Missing item is a cheap add-on | Ship now; refund or swap the add-on | A second parcel can cost more than the add-on earns |
| Missing item is the main product | Ask the customer | Some would rather wait than get the accessory alone |
| Gift or date-sensitive order | Ship what makes the date; tell the customer clearly | A late gift is a refund request either way |
| US destination, both items small | Lean toward one parcel | Each parcel from China is now its own US import paying duty |
| Pre-order mixed with in-stock items | Follow the policy shown at checkout | Decide it once, before customers ask |
One rule beats all of these: tell the customer before the first parcel arrives. Two parcels they expected are fine; one parcel with missing items and no explanation turns into a "you sent me the wrong order" ticket.
What a second parcel really costs
Take a two-item order of two different products, shipped on a day when it falls in our first pick-and-pack tier.
- Packed together: the pick-and-pack fee is $2.00 for the order plus $1.00 for the second SKU, so $3.00. There is one shipping charge, one tracking number and one customs entry.
- Sent apart: the second item needs its own packaging, its own label and its own shipping charge. Parcel lines price each parcel separately, so two light parcels usually cost more to send than one parcel holding both items.
- Into the US: since the $800 duty-free threshold no longer applies, each parcel from China is a separate import that pays its own duty. Two parcels mean two entries to prepay.
- Support time: two tracking numbers mean two shipping emails, and the "only half my order arrived" message you may have to answer.
So splitting is worth it when the wait would cost you more than all of the above: a cancellation, a dispute, or a gift that misses the day. Your account manager can send the current price of each shipping line, and the full fee table is on our pricing page.
Recording a partial shipment correctly
Shopify
- Fulfill only the quantities that actually shipped, each with its tracking number. Shopify keeps the rest on the order as Unfulfilled, and the order shows Partially fulfilled.
- Each fulfillment can send its own shipping notice, so the customer sees exactly what is on the way.
- If a line will ship later, you can put just those items on hold, so nobody packs them by mistake.
- If a line won't ship at all, refund it. Once nothing is left to ship, the order closes as Fulfilled.
WooCommerce
- By default the order stays in Processing until everything has shipped. Don't set it to Completed early: that sends the customer the "order completed" email.
- The optional Fulfillments feature, introduced as a beta in version 10.2, records each shipment with its own tracking and shows the order as Partially Fulfilled until the last one goes.
Marketplaces
Amazon, TikTok Shop and others have their own partial-shipment flows and deadlines. Whatever you do there, confirm each shipment with its real tracking number, and don't leave the second shipment hanging past the marketplace's dispatch window.
What to tell the customer
- When you split: "Your order is coming in two parcels. [Item] is on its way today; [item] follows by [date]. You'll get a tracking link for each."
- When a line is cancelled: "[Item] is out of stock and we couldn't get more in time, so we've refunded it. The rest of your order has shipped."
- When you offer a choice: "One item is delayed until [date]. Would you like us to send everything together then, or the in-stock items now?"
How to see fewer partial fulfillments
- Hold stock of your best sellers where your orders ship from, so a supplier stock-out doesn't reach your customer.
- Consolidate. Have every item of an order packed into one parcel at one warehouse, instead of letting each supplier ship its own.
- Inspect on arrival, not at packing, so defects are replaced before any order is waiting on them.
- Keep a backup supplier for each best seller.
- Route to minimize splits. If you hold stock in more than one location, Shopify's order routing can favor the location that holds the whole order.
- Watch the queue. A Partially fulfilled order with no date on its missing lines is a stuck order; our guide to stuck Shopify orders covers the checks.
How PackQuay handles multi-item orders
Every item of an order is bought, received and checked at our own warehouse in Xinxiang, then packed together, so a multi-item order leaves as one parcel with one tracking number. We can ship items separately if you ask. We inspect 20% of goods free on arrival and send faulty units back to the supplier, and if an item can't be sourced, your account manager tells you so you can decide between waiting, a swap or a refund. Stocked orders leave within 24 hours (48 at peak). Talk to us on WhatsApp.
FAQ
What is the difference between unfulfilled and partially fulfilled?
Unfulfilled means nothing in the order has shipped. Partially fulfilled means at least one item has shipped and at least one is still waiting.
Why is my order partially fulfilled?
Usually because one item was out of stock, stored in a different location, on pre-order or replaced after a quality check, so only the rest could ship. It can also happen when separate suppliers each ship their own item.
Should I ship a partial order or wait for all items?
Wait if the missing item will be ready within a day or two, because one parcel costs less and confuses no one. Ship what you have if the gap is long or uncertain, and offer a swap or refund for the missing item.
Does a partially fulfilled order cost more to ship?
Usually. The second parcel needs its own packaging, label and shipping charge, and for US customers each parcel from China is a separate import that pays its own duty.
When does a partially fulfilled order become fulfilled?
When the last open item ships, or when the items that won't ship are refunded or removed so nothing is left to send.
