Why teams connect DEAR Inventory and Syspro
Two ERPs, one set of facts: Stacksync keeps DEAR Inventory and Syspro 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 Customers, Suppliers, Stock adjustments and transfers, Assemblies / Production in DEAR Inventory with AR invoices, GL journals, Warehouses, Customers in Syspro 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 Sync stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.
- 02 Push sale orders from a storefront or CRM into DEAR for fulfillment without manual re-entry.
- 03 Post shipment confirmations from logistics systems back against SYSPRO sales orders
- 04 Write sales orders from e-commerce platforms or CRMs into SYSPRO without manual re-entry
Common sync patterns
Split by function
Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.
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.
What you can sync between DEAR Inventory and Syspro
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.
| DEAR Inventory objects | Syspro objects | How this pairing syncs | |
|---|---|---|---|
| Sale orders Customer orders through their pick/pack/ship lifecycle; synced with storefronts and CRMs. | Sales orders Orders written in from storefronts and CRMs, with status read back out. | 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. | |
| Purchase orders Supplier orders and receiving records synced with accounting and planning tools. | Purchase orders Procurement documents synced with supplier portals and receiving. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Customers Buyer records aligned with CRM and accounting counterparts. | Customers AR customer master records matched against CRM accounts. | 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. | |
| Suppliers Vendor records referenced on purchase orders. | Suppliers AP supplier records synced with procurement and payment systems. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Stock levels Per-location availability derived from inventory transactions; read-heavy in storefront syncs. | Jobs (work orders) Manufacturing jobs and WIP tracked for production reporting. | Stock levels is specific to DEAR Inventory and Jobs (work orders) to Syspro — each maps to any object or custom field on the other side. | |
| Stock adjustments and transfers Inventory movement transactions that explain changes in availability. | Bills of materials Product structures referenced when syncing manufacturing data. | Stock adjustments and transfers is specific to DEAR Inventory and Bills of materials to Syspro — each maps to any object or custom field on the other side. |
How changes propagate between DEAR Inventory and Syspro
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.
DEAR Inventory Syspro Sub-second propagation
DetectionDEAR Inventory notifies Stacksync of record changes through webhook events. Polling with modified-since filters.
DeliveryEach detected change is written to Syspro through its API, with automatic retries and rate-limit backoff.
Syspro DEAR Inventory Interval-based propagation
DetectionStacksync polls Syspro for changes on an incremental schedule, reading only records changed since the previous pass. Polling.
DeliveryEach detected change is written to DEAR Inventory through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- DEAR Inventory: Subject to the platform's per-account API rate limits.
- Syspro: Throughput depends on the customer's server sizing; many deployments are on-premise.

FAQ
DEAR Inventory and Syspro integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between DEAR Inventory and Syspro: authenticate both systems, choose the objects to sync (such as DEAR Inventory's Sale orders and Purchase orders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed DEAR Inventory and Syspro connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom DEAR Inventory–Syspro integration in-house.
-
Yes — Stacksync ships production-grade connectors for both DEAR Inventory and Syspro. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on DEAR Inventory: Polling with modified-since filters; webhook notifications for sale and purchase events are available on subscriptions that include the Automation module. On Syspro: Polling; the ERP does not expose a change feed to external consumers. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the DEAR Inventory side: Customers, Suppliers, Stock adjustments and transfers, Assemblies / Production, plus custom fields where DEAR Inventory exposes them. On the Syspro side: AR invoices, GL journals, Warehouses, Customers. Stacksync auto-detects both schemas and converts types between the two systems.
-
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.
