Why teams connect Attio and Unleashed Software
Close the gap between front office and back office: Attio and Unleashed Software share customers and status in real time, in both directions.
Attio holds the customer relationship; Unleashed Software runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.
Stacksync syncs Users, Deals, Workspaces, Custom objects in Attio with Bills of Materials, Invoices, Products, Stock On Hand in Unleashed Software field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Common use cases
- Run a two-way dual-run when migrating to Attio from another CRM.
- Sync companies, people, and deals with Postgres so ops teams enrich and update CRM records with SQL.
- Keep Products and pricing aligned between Unleashed and accounting or PIM systems.
- Mirror Purchase Orders and supplier data to a data warehouse for procurement reporting.
One customer master
Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.
Where Unleashed Software manages people and org data: keep Attio aligned
Owners, territories, and org structure informed by Unleashed Software stay current in Attio.
Where Unleashed Software handles order-to-cash: closed-won flows through
A deal won in Attio creates or updates the customer in Unleashed Software with clean data, so fulfillment and invoicing start without re-entry.

FAQ
Attio and Unleashed Software integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Attio and Unleashed Software: authenticate both systems, choose the objects to sync (such as Attio's Custom objects and People), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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.

Common patterns for Attio and Unleashed Software: One customer master; Where Unleashed Software manages people and org data: keep Attio aligned; Where Unleashed Software handles order-to-cash: closed-won flows through. Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

Attio: REST API. Authentication: Guided in-app connection ("Attio CRM" connection created in a few clicks, "without any coding required"); the docs do not name the underlying auth mechanism (OAuth vs API key). Unleashed Software: REST API. Authentication: API ID plus API key, with each request signed using an HMAC-SHA256 of the query string. Stacksync manages authentication, retries, and rate limits on both sides.
-
Attio: Docs do not document the authentication mechanism, change-detection method, or write/CDC/webhook behavior for Attio. Unleashed Software: Inventory quantities are tracked per warehouse, so stock syncs are warehouse-scoped rather than a single global figure. Stacksync's field mapping accounts for these differences between Attio and Unleashed Software 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 Attio and Unleashed Software records are not retained after a sync operation.
