A 3PL's cutoff is the time of day an order has to reach the warehouse to ship that same day, and its SLA (service level agreement) is the promise about how fast every other order ships and how accurately. Measure both from your own order export: when each order synced, when the carrier first scanned it, and whether the right units arrived. A miss costs you a support ticket, a reship, or a mark on your TikTok Shop or Amazon account, so count misses one order at a time instead of trusting a monthly average.
Here's how the two fit together, what happens to an order that lands five minutes late, a table for measuring each SLA yourself, what a miss costs, and what your dashboard should show you every morning.
What's the difference between a cutoff and an SLA?
The cutoff is a clock time with a time zone. Orders that sync in before it go into today's pick queue and leave with today's carrier pickup. Ours is noon Eastern, which is 9am on the West Coast, so a customer in Los Angeles who buys over breakfast still makes it.
The SLA covers the orders that miss the cutoff, plus everything else the warehouse promises. It's usually written in business days: an order after the cutoff ships within one business day, for example, or two to three in peak. A full SLA also covers accuracy, how fast an inbound shipment becomes sellable, how fast returns get processed, and how quickly someone answers you. The cutoff decides which day an order counts from, and the SLA decides how many days the warehouse has from there.
Two words need a definition before you can measure anything. A business day usually means Monday to Friday without federal holidays, and you'll want the holiday list. Shipped should mean the carrier scanned the parcel. A label can be printed in the morning while the box sits on a cart until tomorrow, and all the tracking page will say is that a label was created. If the 3PL counts the label, its report and your customers' tracking pages will tell two different stories.
What happens to an order placed at 12:05?
Say a customer checks out at 12:05pm Eastern on a Tuesday. The order syncs from your store in a minute or two, misses the noon cutoff, and joins the queue for Wednesday. Under a one business day SLA it has to ship by the end of Wednesday, so it's picked that day and leaves with Wednesday's pickup at the latest.
Now move the same order to Friday at 12:05. The next business day is Monday, so a customer who bought on a Friday lunch break sees a ship date three calendar days later. Nothing has gone wrong here. That's the SLA working as written, and it's why your store's delivery promise has to know about the cutoff too.
Shopify builds the same idea into its delivery date estimates. Its help center says the business day cutoff is 12 pm in the local time zone of the shipping origin, that an order after it starts fulfillment the next business day, and that fulfillment time ends when you hand the package to the carrier (Shopify Help Center, checked October 2026). If the date your checkout shows and the date your 3PL works to don't match, your customer will hold you to the checkout. The Shopify fulfillment page shows how orders reach our pick queue.
In peak the gap gets longer, because when the SLA on late orders moves to two to three business days, a 12:05 order on the Friday before a holiday weekend can ship in the middle of the following week. Update the delivery promise on your product pages before the season starts, while you still have time to plan around it.
Why the carrier pickup is the real deadline
A cutoff only works if there's time between it and the truck. Carriers pick up from the dock at set times in the afternoon, and every order going out today has to be picked, scanned, packed, labeled and staged on the right carrier's cart before that truck leaves. Ask a 3PL when each carrier picks up, and how many hours that leaves after the cutoff on a heavy day.
A late pickup can make a missed SLA look like a met one. If the warehouse counts orders by label time, a box that missed the truck still shows as shipped today. Check a sample against the carrier's first scan. If the first scan lands the next morning on orders the report calls same-day, either the pickup is late or the boxes missed it, and you'll want to know which.
Pickup windows also explain why faster services sometimes need an earlier cutoff, since overnight and two-day services can be collected earlier than ground. If you sell express shipping at checkout, ask whether those orders have a cutoff of their own, and put it on your shipping page.
How to measure each SLA from your own order export
You don't need the 3PL's report to measure its SLA. Export three months of orders from your store with the order time, the fulfillment time and the tracking number, then look up the first carrier scan for a sample. Here's what to measure and how to count it.
| What's measured | How to measure it | What counts as a miss |
|---|---|---|
| Same-day ship on orders before the cutoff | Of the orders that synced before the cutoff, the share with a first carrier scan that business day | A first carrier scan on a later day, whatever time the label was printed |
| Ship time on orders after the cutoff | Business days from order sync to first carrier scan, using the holiday list in the agreement | More business days than the SLA allows, in a normal week or in peak |
| Order accuracy | Orders with a wrong item, a missing unit or a wrong address, divided by orders shipped, counted per order | Any order your customer reports and the warehouse confirms after checking its scans |
| Tracking back to your store | Time from the label being printed to the tracking number showing on the order in your store | Tracking that shows up after the customer has already asked where the order is |
| Receiving | Time from the truck at the dock to the units showing as sellable in the dashboard | Stock sitting unsellable past the window the agreement names |
| Returns | Business days from a return reaching the warehouse to graded, restocked or set aside, and the refund sent | Returns sitting in a pile while customers wait for their refunds |
| Response time | Time from your email or ticket to a reply from someone who can act on it | A reply that acknowledges the problem without an answer or a time for one |
Run it every month and keep the order-level list. A monthly percentage hides the patterns you most need to see, like every Monday running late because the weekend's orders swamp the morning. If the 3PL reports an SLA number, ask for the list behind it with order time, ship time and first scan, and check twenty orders yourself. The order fulfillment process guide walks through each step an order passes, which helps when you're working out where the hours went.
How much does a missed SLA cost you?
On your own store a late order costs you a where's-my-order email, sometimes a refunded shipping charge, and a customer who's less sure next time. On a marketplace it goes on your account, because the marketplace measures you, whoever packed the box.
TikTok Shop's US fulfillment policy says regular orders must be marked In Transit, for example by a carrier scan, within 2 business days of Awaiting Shipment, and Delivered within 6 business days. It recommends a late dispatch rate at or below 4%, says enforcement actions may apply above 10%, and counts business days without Saturdays, Sundays or US federal holidays (TikTok Shop fulfillment policy, checked October 2026). Amazon's selling policies page tells sellers who ship their own orders to keep the late shipment rate ideally under 4% to avoid deactivation of seller-fulfilled offers, the order defect rate under 1%, and the cancellation rate below 2.5% (Amazon selling policies, checked October 2026).
Those rates turn a 3PL's SLA into a risk to your account. Assume you ship 1,000 TikTok Shop orders a month, so 40 late dispatches put you at the recommended line and more than 100 put you over the enforcement line. A 3PL that now and then misses its own one-day SLA still clears TikTok's window. One that runs two days behind on a busy Monday won't, and the TikTok Shop fulfillment page covers how those orders run here.
On your own store the cost shows up in tickets. Tag the ones that ask where an order is, line them up against ship dates, and you'll see how much support time one late day buys. Then ask the 3PL what it does when it misses: a credit, a fix with a date, or a way out. The contract terms guide covers how that clause should read, so we won't repeat it here.
What your dashboard should show every morning
You shouldn't have to wait for a monthly report to find out you missed. A useful dashboard should show these live:
- Orders by status, from synced to picking, packed and shipped, with the ones past their ship-by time at the top.
- Today's orders split into before and after the cutoff, so you can see what has to leave today.
- SLA by day for the last month, with each miss clickable down to the order.
- Inventory by SKU, so an oversold item shows up before it turns into a cancellation.
- Inbound shipments with their arrival and sellable dates, and returns waiting to be graded.
If a 3PL can only send you a spreadsheet at the end of the month, you'll find out about a bad Tuesday three weeks after your customers did.
How the cutoff and SLA work at YNK
Orders in by noon Eastern (12pm ET) ship the same business day. Anything later goes out the next business day, or within two to three business days during peak. The cutoff doesn't move in December. What changes in peak is the SLA on orders after the noon cutoff, from one business day to two or three, and your rates stay where they are, with no seasonal or peak surcharges on handling or storage.
Every major carrier picks up from Elmwood Park daily. Before anything goes in a box, someone scans it against the order, so a six-unit order is six scans, and pick and pack error runs under 0.3% across more than 1.2 million orders a year. Shopify, Amazon and TikTok Shop orders sync into ShipStation, our WMS, ship on the same cutoff, and tracking syncs back to your store. You get the same live dashboard we use for our own brands, with orders, SLA and inventory, plus a weekly review of order flow, SLA and inventory with your account manager. The services page has the rest.
The SLA has been tested. Nominal called a warehouse sale at the last minute, more than 10,000 orders landed in one weekend, and every one shipped within SLA (the Nominal case study). From our building in Elmwood Park, New Jersey, about 15 miles from Manhattan, ground reaches New York, New Jersey, Pennsylvania, New England and the DC area in one to two business days, and the rest of the country in about five.
If you'd like to see our SLA against your own orders, send the 3PL intake with your last three months of shipments. It takes about ten minutes, someone from the team replies within one business day, and the proposal follows within five. The FAQ has the cutoff and peak answers in one place.
Questions founders ask about SLAs and cutoffs
What's a normal 3PL cutoff time?
There's no single standard, so ask for the time and the time zone. Ours is noon Eastern. What matters more is how many hours the warehouse has between the cutoff and the last carrier pickup, and whether orders before the cutoff actually get a carrier scan that day.
Does the SLA clock start at checkout or when the order reaches the 3PL?
Ask, because it changes the number. The fairest clock starts when the order syncs from your store into the warehouse system, which is usually within minutes of checkout. An order you hold, like one flagged for fraud review, should start its clock when you release it.
Is a 3PL's SLA the same as delivery time?
The SLA only runs until the carrier scans the parcel, and delivery adds the carrier's transit time on top, which depends on the service and the distance. From Elmwood Park, ground is one to two business days across the Northeast and about five coast to coast.
What should happen when a 3PL misses its SLA?
You should hear about it before your customers do, with the orders affected and the cause. After that, your agreement decides: a credit, a fix with a date, or a way out. Our contract terms guide covers how to word it.
