Improve outcomes that matter to you and your customers with every shipping decision optimized for speed, cost, and accuracy—in real time.

Regular 2-day shipping is possible with software

Many retailers are surprised to know they can regularly hit 2-day delivery dates for customers without having to pay for Next-Day Air methods. Shipium applies automation and sophisticated modeling technology to create faster delivery speeds for less, which is critical to meet changing consumer expectations.

91% Consumers who abandon cart if shipping isn't free or fast enough
44% Consumers who did not purchase because shipping was too slow
70% Consumers who expect a 2-Day shipping option
39% Consumers who expect a free 2-Day shipping option

Reduce shipping costs 5% or more

Complexity is good, as it's a typical sign of sales and shipping growth. When retailers use multiple carriers and methods, savings can be found through arbitrage. But wrangling that complexity is difficult, especially at scale. Shipium gives retailers a way to add new carriers to all warehouses in a single afternoon, then automates carrier selection based on cost optimization.

Did we say 5%? We meant 20%+

Deploying a multi-carrier strategy that utilizes Carrier Selection's contract and surcharge virtualization tools will have a transformative impact on your cost structures. If what you have today with a carrier or two is good enough, then why aren't you reducing your costs by 20%?

How Carrier Selection Works

Customers replace their TMS with our API-first platform to give them modern flexibility, scalability, and reliability.

Integrate with your WMS

Shipium Carrier Selection APIs are called at the moment of pick-and-pack in order to return the best shipping label for a shipment. Integration is uncommonly fast, and our team of implementation managers is ready to get you started.

Send us shipment information

A simple API request with origin, destination, and shipment properties is all that's required.

We check eligibility for you ("Gate Shopping")

Because Shipium is a centralized cloud platform, we only integrate into a carrier once, and when completed, the carrier is available to all customers. Part of the carrier integration process is our team noting all eligibility criteria for a carrier and method. We'll know that a P.O. Box must use USPS methods, or lithium ion batteries can't use air methods, or that a certain regional carrier doesn't deliver to zones 6-8. The first phase of our selection process checks eligibility requirements of all methods available to you, thus eliminating almost all business rules you would have to set up yourself in a TMS.

We predict with precision which methods will hit a delivery date ("Date Shopping")

If a shipment must hit a specific delivery date, we stochastically model out the probability of each method hitting that date. This is different than every other TMS which will simply check the carrier SLAs. With Shipium, a 5-Day Ground method might still be in scope because it always is delivered ZIP<>ZIP in two days whereas other offerings will disqualify it.

We model rates in-memory and pick the cheapest option ("Rate Shopping")

After the first two steps, we only then do rate shopping. Given eligible methods, we model the probable price with precision based on customer contracts set on the platform. Once we identify the cheapest option, it is only then that we make a call to the carrier API to print a label. The whole selection process can be completed in a fraction of a second, dramatically improving throughput and performance.

We manage manifesting and labels

The selection process completed by Shipium handles the returning of a label to print and manifesting the shipment with the carrier.

  • Custom label augmentation
  • Adjust label sizes
  • ZPL or PDF formats
  • Tenant customization

Modern technology

World-class engineering that gives you flexibility, scalability, and reliability

Our centralized cloud platform was built from the ground up to support high-volume retail. The enterprise-grade horsepower means customers can kiss the performance issues of their existing TMS goodbye.

Move to a cloud-based future

Shipium is a centralized cloud platform which means customers achieve incredible leverage and scale across their physical operations. Gone are the days of on-premise installations that haven't been updated in years.

Carrier fallback is standard

Some carrier APIs can be unreliable and return errors when calling for a label. Our system accounts for this commonality by elegantly falling back to the next best method if there is a technical problem retrieving a label.

Scalable and elastic

Bottlenecks are eliminated because the platform performs key computations in-memory on the cloud. Other rate shopping offerings make a call to every carrier API for every call, resulting in a multi-second job. We processed 10K shipments per minute during 2021 peak season, and automatically scale higher to meet increased customer demand.

Robust carrier network

Integrated carriers are immediately available to every customer on the platform

Adding a carrier is as simple as uploading a new rate card

Shipium is a centralized cloud platform which means customers achieve incredible leverage and scale across their physical operations. Gone are the days of on-premise installations that haven't been updated in years.

Shipium's transportation ops team manages all surcharges for you

Our team monitors and updates all default surcharges across all carriers and methods on behalf of customers. You will never need to worry about tracking surcharge changes again.

No hidden fees for adding new carriers to your network

There will never be a fee to turn on a new carrier in your network. Simply switch it on and go. In the event that Shipium has not yet integrated with the carrier, we do so for free within an 8-week commitment.

No middleman setting between you and your carrier rates

Shipium does not resell carrier rates because we believe it doesn't help with faster and cheaper shipping. Customers bring their own contracts knowing that those contracts are optimized for their shipping profile.
