Most companies see their ERP as the backbone of their business. It’s where orders are placed, inventory is booked, invoices are processed, and the financial truth of the company resides. Naturally, when a problem arises, the first assumption is that it’s an ERP limitation — and the fix is to bolt on a point solution.

But, over time, this thinking creates a patchwork of specialized systems: one for freight visibility, one for compliance filings, one for inventory tracking, one for vendor management. Each comes with its own architecture, data model, design philosophy, and user interface. None of them talk to each other in a meaningful way, and the result is a supply chain riddled with data silos.

Nowhere is this fragmentation more painful than in the gap between purchase order and warehouse receipt. In most ERPs, once a PO is issued to a vendor, the system effectively goes dark until the products arrive at the dock. For importers, this is the “black hole” of supply chain visibility: weeks or months with little to no insight into the location or status of ordered goods, nor any dependable sense of when they will arrive.

The root of the problem is this: The ERP doesn’t understand what a shipment is. Without that concept, it can’t possibly understand which products are in a shipment, how those products are moving, or what milestones they’ve hit. And without that understanding, it can’t tell you when those products will arrive.

This is the difference between hitting and missing core business outcomes. 

Retailers need to know if seasonal inventory will arrive in time to stock shelves before a promotion. 

Manufacturers need to know if critical components will arrive before a production run. 

Sales teams need to know if customer orders will ship complete and on time.

When the answer is “we don’t know,” it creates a cascade of problems:

• Internal stakeholders can’t plan effectively.
  
• Customer service teams can’t set or adjust expectations with customers.
  
• Leadership can’t assess whether execution is matching the plan (or intervene when it’s not).

The ability to accurately answer “when will it get here?” — and to relay that answer to every stakeholder who needs it, from the warehouse manager to the CFO to the customer — is fundamental to running a reliable supply chain. 

While an ERP can’t answer that simple question, the Shipment-Operations Backbone can. The Shipment-Operations Backbone is a new technology that addresses the legacy challenges shippers face when relying on ERPs for real-time visibility at the product and SKU levels. Keep reading for more on why the Shipment-Operations Backbone has become essential in the modern-day supply chain and logistics landscape.

Why a Backbone Is Necessary

The ERP-centric model fails because ERPs are designed to be the system of record for orders and inventory — not for shipments. They don’t model the reality that, in global supply chains, products move in shipments — each with its own routing, milestones, carriers, and exceptions.

In the absence of a true shipment model, most companies try to solve visibility and execution challenges with point solutions. One tool gives you ETA updates from a freight forwarder. Another tracks milestones from carriers. Another stores compliance documents. Yet another handles customs entries.

The problem, as noted above, is that each point solution has its own architecture, its own data model, and its own orientation. One might be container-centric. Another might be booking-centric. None of them map cleanly back to the ERP’s view of POs, warehouse receipts, and invoices — and they certainly don’t map cleanly to each other.

In supply chain management, this creates two persistent gaps:

1. The PO-to-Warehouse Receipt Black Hole: Once the PO is issued, the company sits in the dark until a container arrives. There’s no consistent way to track the products in transit, match them to specific orders, or forecast arrival dates accurately.
   
2. The Compliance Transformation Problem: In trade compliance, almost every required activity (like creating an ISF, filing a customs entry, and generating a PGA submission) requires transforming a shipment or its transaction-products into a compliance-specific view. Without controlled shipment and transaction-product data, these transformations can’t be done systematically. Compliance work is forced off-system, handled in spreadsheets or email chains, and never incorporated into a controlled, auditable process.
   

The common thread is that, until the shipment is understood in a way that aligns both with the ERP (internal) and the external supply chain (forwarders, carriers, ports, nodes/vectors), you can’t solve these problems in a systematic, sustainable way.

What is the Shipment-Operations Backbone?

To fully understand where ERPs fall short in tracking shipments, it’s important to know what the Shipment-Operations Backbone is. In short, the Shipment-Operations Backbone is a platform that’s designed to account for two control objects:

1. The Shipment

The shipment object represents a single movement of goods. It knows which purchase orders it’s fulfilling, which vendors it’s coming from, which carriers are moving it, and what route it’s taking. It captures every operational milestone along the way — goods ready, in-gate at origin port, loaded on vessel, departure, arrival at destination port, customs release, and delivery to final location. It also records every financial event: base freight, demurrage, detention, and accessorial charges.

2. The Transaction-Product

The transaction-product object represents a specific product instance within that shipment. It links directly to the Product Master (for classification, duty rates, and attributes) and carries the shipment-specific details — quantities, weights, values, and cost allocations. It’s the bridge between the high-level shipment and the granular product data.

Operational Data as the Spine

When every shipment and transaction-product is modeled this way, the Shipment-Operations Backbone becomes the “spine” of the supply chain. Every master data lookup happens in the context of these objects. This is true whether it’s a classification from the PMM or a screening check from the ASM.

With the Shipment-Operations Backbone in place, automation modules no longer have to integrate separately with masters, ERPs, and execution systems. They simply pull the data they need from the Backbone:

• Import automation generates ISF, 7501, and PGA filings from shipment and transaction-product data.
  
• Document ingestion attaches invoices, packing lists, and certificates directly to the shipment record.
  
• Customs audits reconcile broker filings and CBP data against the shipment’s calculated duties.
  
• Reconciliation programs track refunds and PSCs against the original shipment and product costs.
  

The Shipment-Operations Backbone in Action: An Example Workflow

Here’s a hypothetical case study to bring this concept to life.

First, a purchase order is issued in the ERP. The ASN from the vendor is ingested and automatically creates a shipment record in the Backbone, linking it to the relevant POs. Commercial invoices and packing lists are ingested and matched to the shipment, with product lines validated against the PMM and parties screened through the ASM.

From there, the shipment’s milestones are updated automatically from carrier feeds, forwarder updates, or port data. As each milestone hits, estimated delivery dates get recalculated and can be shared instantly with stakeholders.

For compliance, the same shipment and transaction-product records drive ISF filings, customs entries, and PGA submissions — all without rekeying or duplicate data entry. When the shipment arrives, the warehouse receipt in the ERP gets matched automatically, and finance can tie actual freight and duty costs directly to the products received.

WIth the Backbone in place, international shippers can put the challenges of fragmentation behind them. The new lifecycle of a shipment looks completely different. For example, imagine a shipment from a vendor in Shenzhen to a warehouse in Chicago. It would look something like this:

1. PO Issued: The ERP creates a purchase order for multiple SKUs.
   
2. ASN Received: The vendor sends an advance shipment notice. The backbone creates a shipment object and links the relevant POs.
   
3. Booking & Routing: Freight forwarder books space on a vessel, and the shipment record is updated with the planned route (nodes and vectors).
   
4. Document Ingestion: Commercial invoice and packing list are ingested, line items validated against the Product Master, and parties screened against the Account Master.
   
5. Execution Updates: Milestones update as the container is gated in at the port, loaded on vessel, departs, arrives, clears customs, transfers to rail, arrives in Chicago, and delivers to the warehouse.
   
6. Compliance Transformation: The same shipment and transaction-product records generate the ISF, customs entry (7501), and PGA filings — automatically.
   
7. Final Receipt & Costing: The warehouse receipt in the ERP is matched, and actual freight/duty costs are allocated to products using the transaction-product records.

Every milestone, document, and cost is linked to a single shipment record — accessible to every stakeholder.

Benefits of the Shipment-Operations Backbone

The supply chain and logistics moment that we’re currently living through is unique and complex. The old ways, manual processes, and data technologies that shippers once relied upon are no longer sufficient to navigate this challenging landscape. 

The Shipment-Operations Backbone directly responds to modern-day challenges, unleashing a series of benefits for international shippers, including:

• A Single Source of Truth for all in-transit goods, accessible by logistics, compliance, finance, and customer service.
  
• Reduced Integration Cost because every module and external system connects to the same Backbone.
  
• Faster Time-to-Value with configuration over custom development.
  
• Full Traceability from purchase order to warehouse receipt, including every milestone, cost, and compliance action.
  
• Better Stakeholder Communication with accurate, real-time information for both internal teams and customers.

These benefits add up to a serious competitive advantage for international shippers that embrace the Shipment-Operations Backbone as the solution for visibility at the product and SKU levels — and for general supply chain and logistics success.

Beyond Trade Compliance

Trade compliance benefits enormously from this model, but it’s not the only (or even the primary) reason to build a Shipment-Operations Backbone. For companies serious about supply chain reliability, this Backbone is the missing piece between ERP and the external world. It’s the layer that reconciles internal orders and receipts with the physical reality of goods in motion.

Without it, visibility remains partial, exceptions remain reactive, and execution remains a guessing game. With it, the supply chain becomes a managed process — one that supports business outcomes, aligns stakeholders, and makes reliable promises to customers.

The benefits of the Shipment-Operations Backbone stretch across teams, departments, and roles:

• Planners get reliable arrival forecasts, enabling accurate production schedules and inventory positioning.
  
• Customer Service can give customers confident delivery dates and proactively communicate changes.
  
• Compliance Teams automate filings and audits using the same shipment data that operations use.
  
• Finance sees true landed costs in near real-time, tied to specific products and orders.
  
• Executives get a single, unified picture of supply chain performance against plan.

That said, for the Shipment-Operations Backbone to deliver these benefits, it must follow specific architectural principles.

It must be event-driven, powered by milestones, document arrivals, and cost updates triggered by automated workflows.

It must leverage one-to-many integrations that connect the Backbone to the ERP, forwarders, carriers, and customs brokers.

It must deliver master data integrations, with PMM and ASM feeding directly into shipment and transaction-product records.

And it must feature Open APIs that allow for easy connections to new systems or data sources without re-architecting.

The Shipment-Operations Backbone: An Entirely New Way to Work

Traditionally, international shippers and their customers have grown accustomed to an ERP showing a PO issues — and then nothing until the warehouse receipt. They’re used to managing multiple point solutions, generating arrival dates based on guesswork (or the last email from a forwarder), working in spreadsheets, and scrambling to reconcile freight and duties weeks after goods arrive.

The Shipment-Operations Backbone creates an entirely new way to work.

The Backbone creates a single system that knows every shipment (and the products in it) from PO to delivery. It automatically updates arrival forecasts and milestones hit. It allows internal and external stakeholders to see the same data. And it allows for the accurate and immediate calculation of total landed costs.

Perhaps most importantly, the Shipment-Operations Backbone gives every stakeholder, internal and external, accurate and timely answers to that persistent question: “When will it get here?” And it transforms trade compliance from a manual, reactive function into a controlled, automated process.

For importers, the Backbone is the new foundation of daily operations and insight. Without it, every attempt at visibility, automation, or compliance will be limited by the same underlying problem: You can’t manage what you don’t understand. The Shipment-Operations Backbone is how you finally understand your shipments.
