Why teams connect Microsoft Dynamics NAV and SAP Business One

Two ERPs, one set of facts: Stacksync keeps Microsoft Dynamics NAV and SAP Business One 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 Sales Orders & Invoices, Purchase Orders, G/L Entries, Item Ledger Entries in Microsoft Dynamics NAV with Deliveries, Journal Entries, Warehouses, Price Lists in SAP Business One 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 Push ecommerce orders into NAV sales orders through published page services.
  • 02 Replicate G/L and ledger entries into a warehouse for consolidated finance reporting.
  • 03 Two-way sync of business partners between SAP Business One and a CRM so sales edits and finance records converge on one customer master.
  • 04 Create sales orders in Business One from e-commerce platforms and sync delivery and invoice status back to the storefront.

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 Microsoft Dynamics NAV and SAP Business One

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.

Microsoft Dynamics NAV objects SAP Business One objects How this pairing syncs
Items Item cards and availability mirrored to ecommerce and planning systems. Items Product master data including inventory levels, aligned with e-commerce and warehouse systems. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Purchase Orders Purchasing documents reconciled with receiving and vendor systems. Purchase Orders Procurement documents exchanged with supplier-facing tools. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Vendors Vendor cards aligned with procurement and AP tools. Activities CRM-style tasks and interactions aligned with external sales tools. Vendors is specific to Microsoft Dynamics NAV and Activities to SAP Business One — each maps to any object or custom field on the other side.

How changes propagate between Microsoft Dynamics NAV and SAP Business One

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.

Microsoft Dynamics NAV SAP Business One 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 SAP Business One through its API, with automatic retries and rate-limit backoff.

SAP Business One Microsoft Dynamics NAV Interval-based propagation

DetectionStacksync polls SAP Business One for changes on an incremental schedule, reading only records changed since the previous pass. Polling on update timestamps.

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