Why teams connect DEAR Inventory and Sage 300

Two ERPs, one set of facts: Stacksync keeps DEAR Inventory and Sage 300 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 Purchase orders, Customers, Suppliers, Stock adjustments and transfers in DEAR Inventory with AP Vendors, GL Accounts, Journal Batches, Order Entry Orders in Sage 300 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

  • Sync stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.
  • Push sale orders from a storefront or CRM into DEAR for fulfillment without manual re-entry.
  • Replicate GL, AR, and AP detail to a warehouse for consolidated multi-company reporting.
  • Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.

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.
