Picking, Packing, and Proof of Delivery: Why 3PLs and Warehouse Operators Are Replacing Legacy Dynamics WMS

What Makes the 3PL Business Model Uniquely Challenging for Legacy Dynamics ERP?
Third-party logistics providers operate a business model that legacy ERP systems were not designed to support. Unlike a manufacturer or distributor that manages inventory it owns, a 3PL manages inventory that belongs to multiple clients, with different storage configurations, handling requirements, billing structures, and reporting obligations for each.
Legacy Dynamics GP and AX were built for companies that manage their own inventory against their own financial statements, adapting them for the multi-client, service-billing model of a 3PL requires either significant customization or ongoing manual workarounds.
The most common pain points that 3PLs describe when running on legacy Dynamics: client billing processes that require manual extraction of activity data from the WMS and manual entry into GP, inventory reporting that can't differentiate between client-owned stock without custom reports, rate card management that requires IT involvement every time a client's billing structure changes, and proof of delivery documentation that lives outside the ERP system and must be manually associated with billing records.
How Does D365 Advanced Warehouse Management Differ From Legacy Dynamics WMS?
D365 Supply Chain Management's Advanced Warehouse Management (AWM) module provides warehouse management capabilities, directed picking, wave processing, license plate tracking, multi-location bin management, and mobile device workflows, natively within the ERP rather than through a separate WMS application. This integration eliminates the interface between ERP and WMS that creates billing delays and reconciliation problems in legacy environments.
D365 AWM supports warehouse configurations that legacy Dynamics WMS cannot match: multi-client inventory ownership within a single warehouse, client-specific slotting and put-away rules, product-specific handling instructions that appear on mobile device picking screens, and real-time inventory positions by location that are updated with each scan transaction. For 3PLs that are managing twenty or more clients in a single facility, the ability to maintain client-specific inventory configurations without separate system instances is a meaningful operational improvement over legacy WMS architectures.
What Does the D365 Billing and Client Reporting Model Look Like for 3PLs?
The 3PL billing model in D365 is built on the Sales Order and Service Contract modules, with billing events triggered by warehouse transactions. When a receiving transaction is completed in D365 AWM, a billing event for receiving services can be triggered automatically for the appropriate client. When a shipment is picked and confirmed, outbound handling charges post to the client's service account. Monthly storage billing runs against current inventory position data in D365, not against a separate WMS extract.
Rate card management in D365 is maintained through configurable pricing agreements and trade agreements that apply to specific clients, product categories, or service levels. When a client's billing structure changes, the rate card is updated in D365, the billing calculation logic updates automatically without custom report modifications. For 3PLs managing complex multi-client billing structures, this configurability eliminates the IT dependency that makes rate card changes slow and expensive on legacy GP.
What Does the Client Visibility Story Look Like With D365 and Power Apps?
One of the most significant competitive differentiators for 3PLs in 2026 is real-time client visibility, the ability to give clients a web or mobile interface where they can see their current inventory positions, open orders, and recent activity without calling the 3PL for a status update. Building this capability on legacy Dynamics requires custom web development, API integration, and ongoing maintenance. Building it on D365 with Power Apps requires a competent Power Platform developer and a few weeks of configuration work.
Power Apps client portals connecting to D365 data give 3PL clients real-time inventory counts by location, order status tracking from receipt through shipment, automated exception notifications for inventory discrepancies or shipment delays, and self-service reporting access. For 3PLs competing for contracts with larger shippers and brands, this visibility capability has become a contract requirement rather than a differentiator, clients who have experienced real-time visibility don't go back to weekly email reports.
What Should 3PLs Evaluate Before Moving to D365?
D365 Supply Chain Management with Advanced Warehouse Management is best suited for 3PLs and warehouse operators with ten or more clients, significant complexity in billing structures or handling requirements, and the operational scale to justify the implementation investment. Smaller 3PLs with simpler operations and fewer clients may find the implementation scope larger than their needs require.
Turnkey Technologies has worked with warehouse operators and third-party logistics providers to implement D365 AWM in environments ranging from single-client dedicated warehouses to multi-client public warehouse operations. If your current billing process requires extracting data from your WMS before you can invoice clients, that's a gap worth quantifying before the next client contract renewal.
