Can you integrate Acumatica with Microsoft Dynamics NAV?

Yes. Stacksync provides a managed, real-time two-way integration between Acumatica and Microsoft Dynamics NAV: authenticate both systems, choose the objects to sync (such as Acumatica's Customers and Vendors), map fields visually, and changes propagate both ways in milliseconds — no code required.

Which Acumatica objects can I sync with Microsoft Dynamics NAV?

On the Acumatica side: Projects, Opportunities and Cases, Customers, Vendors, plus custom fields where Acumatica exposes them. On the Microsoft Dynamics NAV side: Item Ledger Entries, Dimensions, Companies, Customers. Stacksync auto-detects both schemas and converts types between the two systems.

Can the Acumatica–Microsoft Dynamics NAV sync run one-way instead of two-way?

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

How do teams use the Acumatica and Microsoft Dynamics NAV integration?

Common patterns for Acumatica and Microsoft Dynamics NAV: Two-tier roll-up; Migration in parallel; Shared master data. Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.

What should I know about the two APIs?

Acumatica: Contract-based REST API (JSON over versioned endpoints), plus SOAP web services and OData access to Generic Inquiries. Authentication: OAuth 2.0 or cookie-based session login with Acumatica credentials. Microsoft Dynamics NAV: SOAP and OData web services published from NAV pages and codeunits; direct SQL Server access on-premises. Authentication: Windows authentication or NavUserPassword credentials. Stacksync manages authentication, retries, and rate limits on both sides.

What makes Acumatica's data model different?

Acumatica: Custom fields defined in the instance can be added to the API entity contract, so tenant customizations participate in syncs alongside standard fields. Microsoft Dynamics NAV: Business logic lives in C/AL codeunits; writes through page services run that validation, while raw SQL writes bypass it and are riskier. Stacksync's field mapping accounts for these differences between Acumatica and Microsoft Dynamics NAV without custom code.

Why teams connect Acumatica and Microsoft Dynamics NAV

Two ERPs, one set of facts: Stacksync keeps Acumatica and Microsoft Dynamics NAV consistent in real time, whether they split the business or one is replacing the other.

Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.

Stacksync syncs Projects, Opportunities and Cases, Customers, Vendors in Acumatica with Item Ledger Entries, Dimensions, Companies, Customers in Microsoft Dynamics NAV bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.

Common use cases

01 Replicate journal transactions and financial data into a SQL database for reporting and consolidation.
02 Sync vendor bills from AP automation tools into Acumatica for approval and payment.
03 Keep inventory availability current in storefronts and customer portals.
04 Run parallel sync during a NAV-to-Business Central migration so both systems stay usable.

Common sync patterns

Two-tier roll-up

Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.

Migration in parallel

When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

What you can sync between Acumatica and Microsoft Dynamics NAV

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Acumatica objects		Microsoft Dynamics NAV objects	How this pairing syncs
Customers AR master data synced with CRMs and billing tools.	⇄	Customers Customer cards synced with CRMs so sales sees ERP balances and terms.	Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
Vendors Supplier records aligned with procurement and AP automation.	⇄	Vendors Vendor cards aligned with procurement and AP tools.	Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.

How changes propagate between Acumatica and Microsoft Dynamics NAV

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Acumatica Microsoft Dynamics NAV Sub-second propagation

DetectionAcumatica notifies Stacksync of record changes through webhook events. Push notifications configurable on data changes, plus polling on LastModifiedDateTime fields.

DeliveryEach detected change is applied to Microsoft Dynamics NAV as a row-level write, with types converted between the two schemas.

Microsoft Dynamics NAV Acumatica Sub-second propagation

DetectionChanges in Microsoft Dynamics NAV are captured at the source via change data capture — no polling loop against its API. Polling on modified/timestamp fields, or SQL Server change tracking/CDC on on-premises databases.

DeliveryEach detected change is written to Acumatica through its API, with automatic retries and rate-limit backoff.
