What a Routing Guide Is: A Retailer's Operational Rulebook

Routing Guide A retailer's instructions governing carriers, routing, appointments, shipment preparation, labels, documentation, and delivery requirements. These instructions are the retailer's operational rulebook for inbound and inter-facility shipments and set the contractual and operational expectations suppliers and carriers must follow.

Retailers use routing guides to standardize the way goods move into their network. A routing guide translates corporate policies — preferred carriers, appointment windows, packaging rules, and required documents — into actionable steps for suppliers, 3PLs, and carriers. For suppliers this prevents invoicing chargebacks; for carriers it clarifies pickup, tendering, and accessorial rules; for warehouses it defines appointment and dock procedures.

What The Routing Guide Typically Covers

Routing guides vary by retailer and product type but commonly include:

• Carriers: Named primary and backup carriers by lane or service level.
• Routing/Service Levels: Which shipments require FTL, LTL, parcel, or expedited services.
• Appointments: How to schedule, cancel, and penalties for missed windows.
• Shipment Preparation: Pallet patterns, weight limits, and consolidation rules.
• Labels And Barcodes: Required label formats, placement, and GS1/UPC expectations.
• Documentation: EDI transaction requirements (e.g., ASN/856), BOL details, and customs paperwork for imports.
• Delivery Requirements: Dock access instructions, receiving hours, and product segregation rules.

Why Retailers Use Routing Guides

Retailers use routing guides to reduce variability and cost in the supply chain. A standardized routing guide reduces denied deliveries, speeds receiving, improves inventory accuracy, and cuts chargebacks. It also helps retailers control freight spend by steering volume to preferred carriers with negotiated rates and by enforcing packaging and consolidation rules that reduce handling.

How Routing Guides Affect Suppliers And Carriers

Suppliers must align processes to avoid penalties. That typically means changing pallet build, submitting EDI documents, and using specified carriers. Carriers must follow tendering rules and appointment protocols. Noncompliance can lead to chargebacks, refused pickup, or a change in routing instructions.

How Routing Guides Vary

Guides differ by retailer scale, product mix, and their use of technology:

• Complexity: Large retailers produce multi-page, lane-specific rules; smaller retailers often provide short checklists.
• EDI Requirements: Some require full EDI flows (POs, ASNs, Invoice); others accept email or portal submissions.
• Service Flexibility: Some guides mandate strict carrier selection; others allow supplier choice with documentation of competitive rates.
• Regional Differences: Domestic rules differ from cross-border or bonded facility rules, especially where customs or special temperature control apply.

Practical Example: A Common Supplier Workflow

A typical flow to comply with a routing guide:

• Receive PO: Supplier reviews the retailer's PO and routing instructions embedded or referenced in the PO.
• Plan Shipment: Determine consolidation, palletization, and required carriers per the routing guide.
• Schedule Carrier: Tender to the prescribed carrier and secure a pickup appointment if the guide requires it.
• Prepare Documents: Create the ASN (856) with carton-level detail and attach required labels and placards.
• Deliver: Follow delivery instructions including dock access and appointment window; capture proof of delivery.

Who Owns Compliance And Who Pays For Failures

Primary ownership of compliance lies with the supplier when the retailer explicitly states instructions on the PO or in the routing guide. Carriers share responsibility for following tender and appointment procedures. Retailers typically publish chargeback policies describing penalties for late shipments, missing documentation, or incorrect labeling — these fees are often deducted from supplier payments.

Tips For Writing And Following A Routing Guide

• Clear Language: Use lane-based tables and checklists rather than paragraphs to reduce misinterpretation.
• Version Control: Publish an effective date and change log to prevent disputes on older shipments.
• Onboarding: Provide webinars or a supplier portal to walk through rules and common errors.
• Exceptions Process: Define an exception approval workflow to handle unplanned events (e.g., carrier outages, force majeure).
• Measure And Iterate: Track chargebacks and root causes; revise the guide to eliminate systemic friction.

In short, the Routing Guide is a practical control tool retailers use to set expectations across suppliers, carriers, and receiving locations. When it's clear, technology-enabled, and enforced fairly, it reduces cost and improves on-time, on-condition deliveries.
