In part 1, we looked at how a Shopify store can compete with Amazon Prime delivery. Our hypothetical business was in Seattle, trying to offer free nationwide delivery. The problem was the other coast: an order from New York City is a long way away, and fast air services cost more than most small orders can carry. So we settled on three-day delivery as a realistic place to start.
It's also worth remembering that Prime isn't really free delivery. Members pay a subscription for it, and the promise depends on Amazon having stock close to the customer. That last part is the real lesson, and it's what this article is about: how you could get to two-day delivery, and what actually stands in the way.
A delivery promise is two numbers added together
Whatever you promise at checkout is the sum of two things: how long it takes you to get an order out of the door (processing, or lead time) and how long the carrier takes to deliver it (transit). Two-day delivery means both have to fit inside two days.
Free two-day delivery from one warehouse
Say you fulfill everything in-house and buy labels in Shopify. In the US, Shopify Shipping supports USPS, UPS and FedEx, and the label screen shows each carrier's services side by side. Some of them are advertised as two-day, but as we covered in part 1, not every "two-day" service is reliable across the whole country.
That leaves the guaranteed air services: two-day air, overnight and priority express products. They work, but from one coast to the other they're expensive, and the price climbs with box size. Rates change often and depend on your account, so check them in your own label screen rather than trusting anyone's published averages. For many small stores, one of the cheaper two-day air services might just fit inside the margin on a larger order. For most, it won't fit on every order.
But suppose your margins can take it. Can you start printing two-day labels tomorrow?
Take time, slow down: the lead time problem
If you get one order a day, packing and handing it over the same day is easy. At volume, it isn't.
Say packing an order and printing its label takes 15 minutes. You work eight hours, but half of that goes on running the rest of the business. Four uninterrupted hours is sixteen orders, before you've driven the parcels to the carrier. If the drop-off takes half an hour, you're down to three and a half hours of packing.
Then there's the cut-off. Every carrier has a daily time by which a package has to be handed over to leave that day. Miss it and the parcel waits until tomorrow, and your two-day promise is already a three-day one before the truck moves.
That's lead time: the time from order to hand-over. If nobody on your team is dedicated to packing and shipping, you probably need a full day of lead time, which leaves one day for transit. From Seattle to New York, that means overnight air, which rules out free shipping for most products.
Warehouse automation isn't the answer for most stores
You could cut lead time to under an hour with an automated fulfillment center. That's how the largest retailers do it, and it takes an investment most independent stores will never make. The practical ways to shorten lead time are simpler:
- set a clear daily cut-off for your own team, and pack everything that arrived before it;
- schedule carrier pickups instead of driving to a drop-off point;
- keep your best sellers pre-packed or in ready-to-ship boxes;
- tell Shopify the truth about your processing time, so the dates it shows are ones you can hit.
On that last point: on Basic and higher plans in the US and some European countries, Shopify can show automated estimated delivery dates at checkout and in order confirmation emails, based on your actual fulfillment history. You'll find them in Settings → Shipping and delivery → Estimated delivery dates. A delivery date you reliably hit does more for trust than a fast promise you sometimes miss.
Building a fulfillment network
The biggest lever isn't lead time, it's distance. The closer your stock is to your customers, the more carrier services become fast enough, and the cheaper they get.
Opening a second shop on the East Coast is a big step. Sending stock to a warehouse that stores and ships it for you is a much smaller one. Spreading inventory across several warehouses like this is what's called a fulfillment network. The main options today:
- A third-party logistics provider (3PL). They store your stock and ship orders. Most connect to Shopify through an app, so orders are sent to them automatically. In Shopify, each warehouse becomes a location, and Shopify's order routing sends each order to a suitable location; by default it prefers the closest location that has everything in stock.
- Flexport. Shopify sold its own logistics business, including Shopify Fulfillment Network, to Flexport in 2023. Flexport now runs that network and is Shopify's official logistics partner.
- Buy with Prime. If you'd rather borrow Amazon's network than compete with it, Amazon's Buy with Prime app for Shopify lets you show the Prime badge and delivery promise on your own store. Orders are fulfilled through Amazon's Multi-Channel Fulfillment, so you need Fulfillment by Amazon set up in Seller Central, a US store selling in USD, Shopify Payments with Amazon Pay, and a Basic plan or higher. You don't have to sell on amazon.com.
Two things to check before you move stock. In the US, holding inventory in another state can create sales tax obligations there, so talk to your accountant first. And if you're shipping fast and reliably, Shopify's Shop Promise badge is worth knowing about: it's shown next to delivery dates and on product pages for stores that meet Shopify's delivery-speed criteria for US orders.
When a fulfillment network makes sense
- demand is high enough that packing is eating your week;
- you'd rather pay per order than hire people for fulfillment;
- orders come from all over the country and shipping costs are hurting your margins.
Getting stock closer to customers is how you close most of the gap with Prime. The rest is the delivery experience around it: honest dates, good tracking emails and easy returns, which small stores can often do better than a marketplace.
