Why This Matters to Your Business
Connect AX 2009 to D365 CRM
Give your commercial teams the full power of Microsoft Dynamics 365 Sales (CRM) while keeping AX 2009 as your rock-solid financial and fulfillment backbone — preserving all core ERP rules and pricing logic.
Instant Balances for Sales
Everything arrives in seconds: your sales reps see live AX customer balances, credit limits, open invoices, and warehouse stock instantly inside CRM, and won quotes convert to AX orders in strict first-in, first-served order.
Scalable & Industry-Standard
Built on industry-standard OData v4, Dataverse Virtual Tables, and Microsoft Entra ID security — delivering a scalable, reusable integration architecture that saves thousands in cloud storage costs.
Four Pillars of the D365 CRM ↔ AX 2009 Solution
1. Live ERP Views with Zero Storage Cost
Because DEAX2K9 provides a standard OData v4 endpoint, Dataverse Virtual Tables connect directly to AX 2009. Your sales reps view live AX 2009 invoices, open customer balances, and warehouse stock levels directly on the D365 Account screen in fractions of a second — without storing a single duplicate row in Dataverse.
2. Two-Way Account & Customer Sync
When a prospect becomes a customer in D365 CRM, DEAX2K9 automatically creates the customer and address book records in AX 2009, assigns the next AX customer account number, and sends it back to CRM. When your finance team updates a customer's credit limit or places an account on hold in AX, CRM is updated within moments.
3. Live Quote Pricing & Credit Checks
While building a quote in D365 Sales, your sales rep can check live AX 2009 pricing and credit availability with a single click. AX 2009 runs its native trade agreement, discount, and credit limit rules and returns the exact net price and credit status immediately.
4. All-or-Nothing Quote-to-Order Sync
When a quote is won in D365 Sales, the order header and all its lines are sent together as a single atomic batch. Either the complete sales order passes all AX 2009 validations and commits cleanly, or it rolls back safely with the exact validation message visible in the AX 2009 Integration Dashboard.
Why Connecting D365 CRM to AX 2009 Is Traditionally Painful
Standard Microsoft cloud connectors assume you are already running Dynamics 365 Finance & Operations, leaving AX 2009 teams with three major obstacles:
No Built-In Cloud Connector
Microsoft's built-in Dual-Write and Dataverse Virtual Table connectors require modern OData v4 endpoints and cannot talk to AX 2009's legacy interfaces.
Complex Customer & Order Rules
Creating a new customer or sales order in AX 2009 spans multiple linked address, party, and inventory tables while relying on AX number sequences and customer-specific trade agreement rules.
High Dataverse Storage Costs
Copying years of historical AX 2009 invoices and warehouse stock balances into Dataverse just so your sales reps can view them quickly burns through expensive Dataverse database capacity.
Business Outcomes
Without DEAX2K9Thousands of dollars per month in extra Dataverse database capacity to replicate historical AX invoices and inventory
With DEAX2K9Major Dataverse storage savings by surfacing live AX 2009 records in seconds via Virtual Tables
Without DEAX2K9Sales reps quote inaccurate prices in CRM because complex AX trade agreements are trapped inside the ERP
With DEAX2K9100% pricing accuracy in CRM powered by live AX 2009 trade agreement and credit calculations
Without DEAX2K9Custom middleware must be thrown away when you eventually upgrade AX 2009 to Dynamics 365
With DEAX2K9Future-proofed: your D365 CRM flows and Virtual Tables already use standard OData v4 Data Entity contracts
