Cutoff times explained: the deadline behind every delivery date

Two shoppers can buy the same product an hour apart and legitimately get delivery dates a full day apart. The reason is a single setting most stores never think about: the order cutoff time.

What a cutoff time actually is

A cutoff time is the last moment in the day when an order can still be picked, packed, and handed to the carrier on that same day. Order before it, and the shipping clock starts today. Order after it, and the clock starts on the next working day — even if your store happily took the payment at midnight.

Think of it as the daily departure time for your fulfilment process. Carriers collect on a schedule, staff finish on a schedule, and no amount of checkout copy changes either one. The cutoff is simply your store admitting, in its date maths, when that departure happens.

Why one hour can move a date by a day — or three

The jump looks dramatic because several rules stack on top of each other:

• Prep time comes first. If an item needs a day of preparation before it can ship, an order placed just after the cutoff does not just lose an evening — it starts its prep on the next working day instead.
• Working days matter. Miss the cutoff on a Friday and the next working day may be Monday. A one-hour miss can become a three-calendar-day shift before transit has even begun.
• Transit runs from dispatch, not purchase. Shipping windows are counted from when the parcel leaves, so every day lost at the dispatch end is a day added at the delivery end.

None of this is a problem when the shopper sees the right date before buying. It only becomes a problem when your product page promised the pre-cutoff date to a post-cutoff order.

Setting a cutoff you can actually keep

The right cutoff is not the latest moment you have ever managed to ship an order. It is the latest moment you can ship an order on a bad day — a late carrier collection, a staff absence, a spike in volume — without heroics. A few principles help:

• Work backwards from the collection. If the carrier collects at 4 p.m., your cutoff needs to leave real packing time before that, not land on 4 p.m. itself.
• Use the warehouse's clock, not the shopper's. The cutoff belongs to the location doing the shipping. If you fulfil from more than one warehouse, each one can honestly run on its own time — which is why Voodoo lets delivery rules account for warehouses and distance rather than forcing one storewide guess.
• Give per-product exceptions room. A personalised or made-to-order product may need an earlier effective cutoff than an in-stock item on the same shelf. Per-product rules and lead times exist so that exception does not drag the whole store's dates later.
• Respect stock reality. A cutoff is meaningless if the item is not actually available to pack. Stock-aware availability keeps the promise attached to what is on the shelf, not what the catalogue wishes were there.

Show the cutoff working, not just the date

The clearest stores do not hide the cutoff — they surface it. A line such as “order in the next few hours for dispatch today” turns an abstract deadline into useful information, and the delivery estimate beside it should update the moment the deadline passes. That is the difference between a static shipping table pasted into a page and a live estimate on your product, cart, and collection pages: the live one knows what time it is.

This is also where honesty protects you. Stretching a cutoff later than your operation can support may win an occasional order today, but it buys a late dispatch, a missed date, and a support conversation tomorrow. As we covered in how to show delivery dates on Shopify product pages, shoppers forgive a realistic date far more readily than a broken optimistic one.

A quick cutoff audit

Before you change anything, walk through five questions. When does the carrier actually collect, and who confirmed it? How long does packing genuinely take at peak volume, not average volume? Which products need prep time before the clock even starts? What happens to a Friday-evening order under your current settings? And does the date on the product page change after the cutoff passes, or does it keep promising today well into tonight? If any answer surprises you, the cutoff — not the carrier — is usually the fix.

The short version

A cutoff time is the hinge every delivery date swings on: before it, today counts; after it, the next working day does. Set it from your real collection and packing rhythm, let prep time, working days, and stock feed the same calculation, and show shoppers the result live. Voodoo Delivery Dates handles cutoff times, prep time, working days, and shipping windows for you, and it is free for your first product, with paid plans at $9.99, $19.99, and $49.99 a month (annual billing saves 30%).
