Estimated delivery
Tue, Oct 6, 2026
6 calendar days after the order, counting 1 processing and 3 transit business days.
This is your own promise to the shopper, not a carrier tracking estimate. Keep a business-day or two of buffer around your real average, so a slow day doesn't break the promise.

How the estimate is built
The calculator checks the order time against your same-day cutoff first. An order placed after the cutoff moves to the next business day before processing starts. From there, it counts your processing days and the carrier's transit days, skipping weekends and any dates you list as holidays or non-shipping days.
Example: the default numbers
- Order placed
- Wed, Sep 30, 2026 at 15:00
- Cutoff
- 14:00 (missed, so processing starts Thu, Oct 1)
- Processing
- 1 business day → ready Thu, Oct 1
- Transit
- 3 business days
Estimated delivery: Tue, Oct 6, 2026 (skipping the weekend of Oct 3-4).
Using it for your "arrives by" promise
- Set the cutoff to match reality. If your warehouse closes at 2pm, orders placed at 1:59pm should still make that day's batch. Check your fulfillment process, not just your storefront copy.
- Widen your holiday list around peak season. Carriers don't move packages on their own holidays, and if you close for a stock-take or a long weekend, add those dates too.
- Shopify. For a live, always-current date on the product page, use the Shopify Estimated Delivery Date Snippet, which runs this same logic in the shopper's browser so it never goes stale on a cached page.
Questions people ask
What happens if an order is placed after the cutoff time?
It's treated as placed the next calendar day before processing time is counted, since it missed that day's outbound batch.
Does this skip weekends automatically?
Yes, if you leave Skip weekends on. Turn it off for a carrier or process that runs Saturdays and Sundays.
How do I add my own holidays?
List them in the holidays field, one per line as YYYY-MM-DD. The default includes Thanksgiving and Christmas 2026 as examples; add your carrier's other holidays or your own closure days.
Is this the same as carrier tracking?
No. It's your own promise based on your processing and the carrier's typical transit time, not a live tracking estimate. Keep a business day or two of buffer so a slow day doesn't break the promise.
