What shippers need to know about carrier integration

Shippers rely on carriers to exchange the information needed to plan, execute, track, and settle freight. Once a shipper and carrier agree to work together, each begins by learning what the other needs to get the job done.

But before the companies can exchange information automatically, their systems and processes must be aligned. A common platform can provide a foundation for that alignment.

Each side must decide what information to exchange, how to format it, and what each field means. Carriers configure and map their systems to the shipper’s requirements while accounting for their own processes. Shippers validate that information can make the round trip as expected.

The work required for each connection depends on both sides: the requirements the shipper brings and the systems and processes the carrier uses. Shippers can make integration easier by providing clear requirements, a repeatable testing process, and connection options suited to different carriers.

Carriers vary widely in size, systems, and technical resources. A global logistics provider may have a team dedicated to integration. At a regional carrier, one person may handle operations, customer requests, and technical questions. For every carrier, moving freight remains the priority. Connecting with a new shipper can grow the business but also create another project that competes with daily operations and service commitments. Carriers may seek to standardize their shipper integrations while remaining open to new customers with different requirements.

Recognizing the need to operate within an ecosystem, logistics leaders must pursue connected logistics with their partners’ needs in mind, not only their internal systems. Supporting flexible connection methods gives more carriers a practical way to participate, regardless of their size or integration resources.

The mix of electronic data interchange (EDI), APIs, data files, and web portals can make carrier integration appear to be a standards problem. One might think that if standards were widely adopted, these formats and methods would eventually converge. But each method provides a valid way to exchange information. EDI standards such as ANSI X12 and EDIFACT support structured business transactions. APIs enable direct exchanges between applications. Data file downloads and uploads offer another way to transfer information, while web portals allow carriers to collaborate with customers without connecting their systems.

Even where formats align, the real challenge comes from each shipper’s unique business requirements, including the specific fields needed, the identifiers used, the business rules applied, and the testing process. A carrier serving several shippers may therefore maintain several versions of what it would prefer to manage as one uniform connection. One connection may require EDI, another an API, and a third may use different rules within the same EDI standard. Each shipper-carrier combination adds configuration, testing, and maintenance.

Carrier onboarding can stall because information that looks correct in one system doesn’t match what another system expects.

A partner identifier may be missing or entered differently in two systems. A location may have several codes. A carrier invoice may use a charge code that the shipper hasn’t configured. A tracking message may include an event code that the receiving system doesn’t recognize. Each mismatch disrupts the flow of information between systems.

Even a familiar term can mean different things to different companies. “Delivered,” for example, might mean arrival at the destination, completion of unloading, or receipt of formal proof of delivery. Unless both systems use the same definition, a valid update may trigger the wrong response or no response at all.

The error may take seconds to make. Finding it can require people on both sides to trace the failed message, identify who owns the data, correct the setup, and test the connection again.

Requirements also vary by transaction. A request for quotation, freight order, tracking update, dock appointment, invoice, and dispute each requires different information and follows different steps.

One mismatch may be manageable. Similar problems across many transactions, carriers, and locations can slow an entire carrier onboarding program.

The table below shows how a network approach can reduce this repeated work without replacing the standards and methods carriers already use:

A working technical connection needs a well-defined process to support it. Communication, requirements, testing, and project management are all responsibilities that cross logistics, operations, finance, and IT. No single team always owns the entire journey.

The knowledge is divided, too. IT may know how to connect the systems but not why a charge, location, or shipment status matters. Operations may understand the business process but not how that information must appear in a digital message. Progress depends on bringing business and technical knowledge together. Yet carrier integration requests must often compete with security work, system maintenance, and other IT priorities.

Shippers and carriers can reduce this friction by treating integration as a defined, repeatable process. Responsibilities, requirements, testing steps, and escalation paths should be clear before work begins. This helps each new connection take hold and remain reliable while supporting a staged approach to logistics modernization.

Freight still has to move when a digital carrier connection is absent or incomplete. Employees fill the gaps by entering information in multiple systems, following up by email or phone, reformatting files before uploading them elsewhere, or logging into carrier-specific portals.

These workarounds may keep individual shipments on track, but manual work can quickly become part of daily operations. Information arrives later, errors are harder to trace, and employees spend more time transferring data between systems.

As a result, people become the connection that technology was supposed to provide. Shippers should focus on reducing the manual work that remains once the carrier begins transacting digitally.

Web portals do serve a purpose, though. Carriers need connection options that match their transaction volumes, systems, and technical resources.

A lower-volume carrier may rely on a web portal to receive requests, confirm orders, schedule appointments, share shipment updates, and submit invoices. A carrier handling more transactions may connect its systems directly through APIs or EDI.

These options can support shared processes such as dock appointment scheduling and freight collaboration, where carriers and shippers need access to the same information.

Better coordination can also enable green logistics by reducing avoidable delays, truck idling, and inefficient handoffs.

Carriers also need clear instructions, ways to check their setup, and support when something goes wrong. They should know what information is required and what a successful test looks like.

A reusable connection can reduce repeated onboarding work. By connecting to a network once, a carrier gains a common foundation for working with multiple shippers instead of starting over with each new relationship. This approach reduces work for both parties and strengthens collaboration across the logistics network.

Digital collaboration can strengthen the relationship and performance of both shippers and carriers, although each partner may not see what happens on the other side of the connection.

To understand the carrier’s perspective, shippers should ask:

• Can carriers choose from several connection methods?
• Can carriers continue using EDI standards?
• Can carriers reuse one connection across multiple customer relationships?
• Are clear onboarding guidance and reliable support available?
• Can regional carriers and large logistics providers both collaborate effectively?
• Does the platform support freight processes from tendering through execution, tracking, and settlement?
• Can information flow securely between the shipper’s and carrier’s core business systems?

These questions show shippers how the platform helps them collaborate with carriers that have different resources and technical abilities.

The platform should also keep carrier information linked to the shipper’s freight orders, purchase orders, sales orders, deliveries, and invoices in the relevant business systems. Without that business context, shippers may gain another stream of data without gaining a clearer view of their operations.

This broader supply chain logistics approach links carrier collaboration with transportation, warehousing, fulfillment, and real-time visibility.

SAP Business Network Freight Collaboration and SAP Business Network Global Track and Trace connect shippers with carriers and logistics service providers across the freight lifecycle. The solutions support tendering, freight ordering, gate and appointment processes, shipment execution updates, document exchange, invoicing, and dispute management.

Shippers depend on carriers for timely quotes, accurate confirmations, useful tracking updates, reliable appointments, correct invoices, and early notice when plans change.

Easier connections allow more carriers to participate in digital processes. Information can arrive sooner with less manual handling, giving shipper teams more time to manage capacity, costs, exceptions, and customer commitments.

The value extends to carriers as well. The C.H. Robinson customer story illustrates how connected freight processes can help a carrier serve its shipper customers more effectively. The global logistics provider uses SAP Business Network for Logistics to provide shipper customers with real-time truckload pricing and quotes. The connection also supports quoting, booking, execution, and payment.

These principles extend across the network: a connected logistics operation depends on shippers and carriers being able to integrate their core processes.

Helping carriers integrate is an investment in the information, capacity, and responsiveness shippers need to run their businesses effectively.

A logistics network becomes stronger when its connections are easier to establish, use, and maintain. When carriers can collaborate more effectively, shippers move forward, too.
