Why teams connect Attio and Sage X3
Close the gap between front office and back office: Attio and Sage X3 share customers and status in real time, in both directions.
Attio holds the customer relationship; Sage X3 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 Companies, Users, Deals, Workspaces in Attio with Sales Orders, Purchase Orders, Work Orders, Stock / Inventory by site in Sage X3 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
- 01 Keep Attio aligned with a billing system or ERP on customer records and plan status.
- 02 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
- 03 Replicate GL journals and sales history to a warehouse for multi-company, multi-legislation reporting.
- 04 Feed work order and BOM data to MES or planning tools on the shop floor.
Common sync patterns
One customer master
Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.
Where Sage X3 manages people and org data: keep Attio aligned
Owners, territories, and org structure informed by Sage X3 stay current in Attio.
Where Sage X3 handles order-to-cash: closed-won flows through
A deal won in Attio creates or updates the customer in Sage X3 with clean data, so fulfillment and invoicing start without re-entry.
What you can sync between Attio and Sage X3
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.
| Attio objects | Sage X3 objects | How this pairing syncs | |
|---|---|---|---|
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | Purchase Orders Procurement documents synced with supplier-facing systems. | Companies is specific to Attio and Purchase Orders to Sage X3 — each maps to any object or custom field on the other side. | |
| Users Synced with incremental and full sync per the Stacksync docs. | Work Orders Production orders read by MES and scheduling integrations. | Users is specific to Attio and Work Orders to Sage X3 — each maps to any object or custom field on the other side. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Stock / Inventory by site On-hand and allocated quantities per site, synced to storefronts and WMS. | Deals is specific to Attio and Stock / Inventory by site to Sage X3 — each maps to any object or custom field on the other side. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Bills of Material Product structures read for planning and costing. | Workspaces is specific to Attio and Bills of Material to Sage X3 — each maps to any object or custom field on the other side. | |
| Custom objects Workspace-defined objects that behave like standard ones in the API. | GL Journals Financial entries replicated to warehouses for group reporting. | Custom objects is specific to Attio and GL Journals to Sage X3 — each maps to any object or custom field on the other side. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | Deliveries Shipment documents synced to logistics providers and customer portals. | People is specific to Attio and Deliveries to Sage X3 — each maps to any object or custom field on the other side. |
How changes propagate between Attio and Sage X3
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.
Attio Sage X3 Sub-second propagation
DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.
DeliveryEach detected change is applied to Sage X3 as a row-level write, with types converted between the two schemas.
Sage X3 Attio Interval-based propagation
DetectionStacksync polls Sage X3 for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled polling.
DeliveryEach detected change is written to Attio through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Attio: Subject to the platform's published API rate limits.

FAQ
Attio and Sage X3 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Attio and Sage X3: authenticate both systems, choose the objects to sync (such as Attio's Companies and Users), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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). Sage X3: SOAP and REST web services published from X3 business objects; direct SQL access to the underlying database on-prem. Authentication: Dedicated web-service user credentials (Basic auth) against configured connection pools. 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. Sage X3: X3 web services are generated from its business objects, so payloads mirror the on-screen entry transactions and enforce the same validation as manual entry. Stacksync's field mapping accounts for these differences between Attio and Sage X3 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 Sage X3 records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Attio and Sage X3 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Attio–Sage X3 integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Attio and Sage X3. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
