• Ensure compliance with carrier standards (EDI, API, label formats, manifesting rules).

• Cartonization & Packing Logic
  • Design and implement cartonization rules that determine how orders are packed based on item dimensions, weights, fragility, and customer-specific preferences.
  • Test and validate cartonization algorithms to ensure cost optimization and compliance with SLA and branding guidelines.

• Validation & Testing
  • Create and execute test plans for carrier mappings, shipping labels, and cartonization workflows.
  • Validate shipping outcomes (service levels, rates, surcharges) against customer requirements and contractual agreements.
  • Conduct regression testing whenever carriers release updates or new services.

• Customer-Specific Requirements
  • Translate client shipping and fulfillment requirements into WMS configuration rules.
  • Customize integrations and workflows for specific use cases (e.g., branded packaging, restricted items, international compliance).
  • Document all customer-specific carrier and cartonization rules for internal and client reference.
• Issue Resolution & Support
  • Troubleshoot integration or carrier mapping issues quickly to minimize impact on fulfillment.
  • Partner with Customer Success, Operations, and IT teams to resolve discrepancies in labels, manifests, or shipping costs.
