Evaluating a Microsoft Dynamics 365 Procurement Integration: What to Ask Before You Sign

Procurement leaders looking at Dynamics 365 tools face a familiar problem: every vendor claims to "integrate," but few explain what that actually means once purchase orders need to move into your ERP. Before you commit budget or IT time, it's worth having a clear checklist for evaluating any Microsoft Dynamics 365 procurement integration.

**Which Dynamics 365 environment does it support?**

Dynamics 365 comes in different forms, and not every connector treats them the same. Ask whether the tool talks to Business Central by default, and whether it can also reach Finance & Operations through OData when you supply an environment URL. If a vendor can't tell you which API they use, that's a gap worth flagging.

**How does it authenticate?**

Look for Microsoft Entra ID OAuth2 with client credentials — tenant ID, client ID, and client secret. You should be the one entering these, not the vendor holding a shared key on your behalf. A genuine connection test should perform a live read, such as pulling the Business Central companies list, so you know the credentials actually work before relying on them.

**What gets sent, and how is it mapped?**

Ask exactly which documents move across — purchase orders are the common starting point — and how fields map to your ERP. Vendor should map to VendorAccountNumber, company to the legal entity (dataAreaId), line items to child records like PurchaseOrderLinesV2 in F&O, and currency to CurrencyCode. If a vendor can't show you a field-level mapping, you're buying a black box.

**Which direction does data flow?**

This matters more than it sounds. Some tools claim to sync ERP data back into the source system. Others, like Complyra, only send documents out to the ERP — they don't import or sync records back. Know which one you're getting, because it changes where your system of record sits.

**Can you test it safely?**

A useful trade-off to check: does the tool let you run exports without live credentials configured, so you can see the process before connecting to production? In Complyra's case, an export without configured credentials completes in test mode, returning a placeholder document number without contacting the ERP.

**Trade-offs to weigh**

Broader ERP coverage often means more configuration. A tighter, single-direction integration is simpler to reason about but requires other tools for anything beyond purchase orders. Decide which trade-off fits your Dynamics 365 setup.
