Why teams connect Acumatica and Linnworks
Two ERPs, one set of facts: Stacksync keeps Acumatica and Linnworks 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 Invoices, Purchase Orders, Stock Items, Shipments in Acumatica with Open Orders, Processed Orders, Stock Items, Stock Levels in Linnworks 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
- Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
- Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.
- Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
- Keep stock levels consistent between Linnworks and external systems so multichannel listings stay aligned with sellable stock
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.

FAQ
Acumatica and Linnworks integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Acumatica and Linnworks: authenticate both systems, choose the objects to sync (such as Acumatica's Projects and Opportunities and Cases), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Acumatica: The contract-based REST API uses versioned endpoints with a defined entity contract, so integrations pin an endpoint version and remain stable across upgrades. Linnworks: Stock is tracked per location, and channel listings are mapped to internal SKUs, which is the join integrations rely on when reconciling marketplace data. Stacksync's field mapping accounts for these differences between Acumatica and Linnworks without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Acumatica and Linnworks records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Acumatica and Linnworks connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Acumatica–Linnworks integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Acumatica and Linnworks. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Acumatica: Push notifications configurable on data changes, plus polling on LastModifiedDateTime fields. On Linnworks: Polling on order and stock endpoints.
