The Speed Factor: Optimizing Fulfillment with Time-in-Transit Calculations

Fulfillment speed is often the defining factor between customer satisfaction and disappointment. But faster delivery doesn’t come for free—it’s a complex balancing act involving shipping costs, warehouse locations, carrier options, and even product-specific needs like refrigeration.

Take perishables as an example. Choosing three-day shipping might save $5 in carrier costs but require an extra $10 in coolant. For frozen goods, that’s the difference between delivering ice cream or a milkshake. Balancing speed and cost is a puzzle we’re constantly solving—and it’s far from a done deal. 

 

Finding the Sweet Spot with Dynamic Order Routing

Whether you’re doing next-day, same-day, or two-day shipping, the goal is the same: automate and optimize that speed factor using a dynamic order algorithm. You want to get to the sweet spot—finding that equilibrium where delivery speed meets cost efficiency without compromising service.

Back in the day, if an order was headed to the West Coast, you shipped it from your West Coast warehouse. Simple, but not smart anymore. What happens when you have five, six, or ten fulfilling nodes?

Is your logic based on zip codes alone? Static rules don’t cut it anymore. Dynamic order routing, powered by techSHIP’s rate shopping engine and rule sets, compares carriers, shipment costs, estimated delivery days, and warehouse priority to select the best fulfillment location for each order.

 

How Dynamic Order Routing Protects Margins

Split shipments kill margins. When I worked in retail, we averaged 1.26 splits per order, which was unacceptable. The first step is getting order routing right to minimize splits rather than managing the symptoms later. Controlling splits with strict rules and blending in inventory availability keeps costs in check.

Consider this: moving an order from a California warehouse rather than a North Carolina may require second-day air instead of one-day ground. The cost difference can completely erase your margin—or worse, create a loss. In perishables, it’s often cheaper to substitute a larger cut of steak for a customer than to split the order across warehouses. Smart routing makes these trade-offs visible and manageable.

 

Using Vendor Scorecards to Drive Reliability

Not all 3PLs or warehouses perform equally. Many retailers rely on a “vendor of last resort”—the partner you use when you want to keep the sale but can’t lean on your preferred warehouses. Vendor scorecards formalize this by ranking fulfillers based on SLA compliance, product mix, costs, and reliability.

techOMS uses delivery cost, time-in-transit, these scorecards to dynamically select fulfillment warehouses. This is not a one-time set-it-and-forget-it setup; it’s a constantly evolving algorithm managed by our team of experts who refine the rules and your team updates the scoring.

 

Applying the Right Criteria for Smarter Fulfillment

Every fulfillment choice balances three key criteria:

  • Lowest cost of delivery
  • Shortest time-in-transit
  • Warehouse priority (your fallback or vendor of last resort)

For perishables, time-in-transit is key—but that doesn’t have to mean air freight. Paying an extra $100 for guaranteed FedEx Express 10 a.m. rarely warrants the increase in shipping than a cheaper ground delivery at 6 p.m.

 

Leveraging Advanced Data Points for Optimization

Additional attributes like expected delivery date and cooling requirements get appended to sales orders and passed to the warehouse management system (WMS). Upgraded shipping, like FedEx Express, can bump orders to a first-wave priority in warehouse fulfillment, ensuring premium customers get faster processing.

This data-driven integration enables smart, automated fulfillment decisions that align business goals and customer expectations.

 

Looking Ahead: Weather, AI, and Smarter Planning

The future of fulfillment lies in factoring in even more variables:

  • Weather conditions: Adjusting coolant needs or routing decisions based on local forecasts.
  • AI-driven insights: Smarter order distribution, inventory placement, and demand planning across warehouses.

These innovations will further drive efficiencies and smarter demand planning.

 

Final Thoughts 

Fulfillment optimization is a complex dance—balancing cost, speed, inventory, and product specifics. Dynamic, data-driven systems like techOMS and techSHIP are mission-critical tools for navigating modern fulfillment challenges.

Just remember: This isn’t “set-it-and-forget-it.” It’s an evolving strategy, constantly refined to meet new challenges. But when done right, the rewards are huge—better margins, happier customers, and a fulfillment operation that hums efficiently.
