The Invisible Barrier to Same-Day Delivery:
Why Real-Time Inventory Visibility is Non-Negotiable

Written By: RANDEMRETAIL

Promising same-day delivery is a powerful way to win customer loyalty, but it's a high-stakes game. If you offer a lightning-fast shipping window only to realize the item is out of stock at the local hub—or worse, stuck in a cross-country warehouse—you haven't just lost a sale; you've lost the customer's trust.

The reality is that same-day delivery is only as good as your inventory visibility. Without a deep, real-time view of your stock, you aren't offering a service; you're taking a gamble.

The Pitfalls of Disjointed Systems

Many retailers rely on a "Frankenstein" tech stack where the Order Management System (OMS) and the carrier module live in different worlds. When these systems don't speak the same language, friction is inevitable.

Disjointed inventory systems
  • Ghost Inventory: Showing "available" on the site when the shelf is empty.
  • The 3rd-Party Lag: Relying on external plugins to calculate shipping availability often leads to slow page loads and inaccurate delivery estimates.
  • Fragmented UX: Customers face a "disjointed" journey where delivery options change or disappear once they hit the checkout.
To gatekeep customer loyalty, you need a unified brain that understands exactly what is available and who can deliver it — before the customer clicks "Buy."

Bridging the Gap Between Your Shelf and the Doorstep

At RANDEMRETAIL, we don't treat shipping as a separate plugin or a "nice-to-have" add-on. We've built our OMS with a native carrier product designed to handle the messy complexities of modern retail without forcing you into expensive, heavy customization.

Real-time inventory and carrier network

Real-Time Intelligence
Our system doesn't guess. It views and understands your inventory levels in real-time, allowing our shipping orchestration to display the right options across the entire journey—from the Product Detail Page (PDP) to the Cart and Checkout.

Split Shipping, Simplified
If a customer wants three items but only one is available for same-day delivery, our OMS handles the split logic automatically. We show the customer exactly what they can get now versus what will arrive later, keeping the experience transparent.

Global Reach, Local Speed
Whether you need the reliability of DHL, FedEx, and Royal Mail, or the local speed of ROADIE (a UPS company) and UBER, it's all connected.

The RANDEMRETAIL Advantage

You don't need to spend months signing individual contracts with 3rd-party last-mile carriers. We provide access to them out of the box, and your support is managed entirely within the RANDEMRETAIL realm.

Same-day delivery isn't just a marketing gimmick; it's a high-stakes logistics challenge. By unifying your inventory visibility and your carrier network within the RANDEMRETAIL OMS, you stop managing "workarounds" and start managing growth.

Turn "Out of Stock" into "Delivered Today."

Whether it's a critical tech upgrade or a must-have home essential, your customers aren't just buying a product—they're buying time. Ensure your backend can actually deliver on the promises your frontend makes.
