Two-way sync
Changes in Attio or ConnectWise instantly reflect in both systems. No stale data, no manual imports.
Keep Attio and ConnectWise in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever ConnectWise holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Time Entries, Invoices, Configurations, Members in ConnectWise to Users, Deals, Workspaces, Custom objects in Attio with bi-directional, real-time sync. Activity and record changes in ConnectWise update the matching contact or account in Attio, and CRM data flows the other way wherever ConnectWise can store and use it.
Enriched fields land directly on records in Attio, and refreshes keep them from going stale.
Charges, refunds, and subscription changes appear on the account in Attio, so revenue context lives with the relationship.
Owner, lifecycle stage, or account details from Attio sync into ConnectWise, so people working there have the context without switching tools.
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 | ConnectWise objects | |
|---|---|---|
| People Standard person object; synced with marketing tools and warehouse person tables. | Service Tickets Support and service desk tickets, including status, board, and priority fields. | |
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | Opportunities Sales pipeline records synced to CRMs for forecasting and handoff. | |
| Users Synced with incremental and full sync per the Stacksync docs. | Agreements Recurring contracts and managed-service agreements used for billing reconciliation. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Projects Project and phase records synced for delivery tracking outside the PSA. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Time Entries Logged technician time, often exported for payroll and invoicing checks. | |
| Custom objects Workspace-defined objects that behave like standard ones in the API. | Invoices Billing records reconciled against accounting systems. |

Yes. Stacksync provides a managed, real-time two-way integration between Attio and ConnectWise: authenticate both systems, choose the objects to sync (such as Attio's People and Companies), 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 ConnectWise: Where ConnectWise supplies contact or company data; Where ConnectWise processes payments; Where ConnectWise can store CRM context: fields kept current. Enriched fields land directly on records in Attio, and refreshes keep them from going stale.
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). ConnectWise: REST API. Authentication: Public/private API key pair for an API member, combined with a registered clientId, sent via Basic authentication. Stacksync manages authentication, retries, and rate limits on both sides.
ConnectWise: List endpoints support a conditions query parameter for server-side filtering on field values, which reduces sync payloads. Attio: Records are distinct from list entries; the same company can appear in multiple lists with list-specific attribute values, which a faithful sync replicates separately. Stacksync's field mapping accounts for these differences between Attio and ConnectWise without custom code.
