Why teams connect Notion and Unleashed Software

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Notion and Unleashed Software.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Notion is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Properties, Blocks, Formula and Rollup properties, Users in Notion with Purchase Orders, Customers, Suppliers, Warehouses in Unleashed Software bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • 01 Push rows from a warehouse or another database into a Notion data source as Pages so ops and leadership read live metrics in a familiar Notion view.
  • 02 Sync a Notion content-calendar database with Jira or Linear by mapping status and date properties both directions.
  • 03 Push Sales Orders from a storefront or CRM into Unleashed for fulfillment without re-keying.
  • 04 Keep Products and pricing aligned between Unleashed and accounting or PIM systems.

Common sync patterns

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.

Where Notion faces customers and Unleashed Software carries account records

Order, invoice, or account status from Unleashed Software appears alongside the customer in Notion, so front-line teams answer from live data.

Where Unleashed Software is the HR or people system of record

Worker and organization data from Unleashed Software stays current in Notion, so the tools people use daily reflect the org as it actually is.

DetectionNotion notifies Stacksync of record changes through webhook events. Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created.

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

Unleashed Software Notion Interval-based propagation

DetectionStacksync polls Unleashed Software for changes on an incremental schedule, reading only records changed since the previous pass. Polling with modified-date filters on list endpoints.

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