Why teams connect ConnectWise and Smartsheet

Stop re-entering the same information in ConnectWise and Smartsheet: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Time Entries, Invoices, Configurations, Members in ConnectWise with Discussions and Comments, Users and Groups, Sheets, Rows in Smartsheet in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • 01 Push closed-won opportunities from the CRM into ConnectWise to kick off agreements and onboarding projects.
  • 02 Reconcile ConnectWise invoices and agreements against the accounting system to catch billing gaps.
  • 03 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
  • 04 Write records from a CRM or ERP into Smartsheet Rows so ops teams manage intake and status in a grid, then push status Cells back to the source.

Common sync patterns

Handoffs between teams

When work started in one tool continues in the other, the shared fields travel with it automatically.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

What you can sync between ConnectWise and Smartsheet

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.

ConnectWise objects Smartsheet objects How this pairing syncs
Opportunities Sales pipeline records synced to CRMs for forecasting and handoff. Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. Opportunities is specific to ConnectWise and Users and Groups to Smartsheet — each maps to any object or custom field on the other side.
Agreements Recurring contracts and managed-service agreements used for billing reconciliation. Sheets The core container; each sheet has typed columns, rows, and a modifiedAt stamp. Stacksync treats a sheet as a table and syncs its rows two-way. Agreements is specific to ConnectWise and Sheets to Smartsheet — each maps to any object or custom field on the other side.
Projects Project and phase records synced for delivery tracking outside the PSA. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Projects is specific to ConnectWise and Rows to Smartsheet — each maps to any object or custom field on the other side.
Time Entries Logged technician time, often exported for payroll and invoicing checks. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Time Entries is specific to ConnectWise and Columns to Smartsheet — each maps to any object or custom field on the other side.
Invoices Billing records reconciled against accounting systems. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. Invoices is specific to ConnectWise and Cells to Smartsheet — each maps to any object or custom field on the other side.
Configurations Managed devices and assets tied to companies, useful for asset inventory syncs. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Configurations is specific to ConnectWise and Reports to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between ConnectWise and Smartsheet

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.

ConnectWise Smartsheet Sub-second propagation

DetectionConnectWise notifies Stacksync of record changes through webhook events. Callbacks (webhooks) on record changes, supplemented by polling on last-updated fields.

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

Smartsheet ConnectWise Sub-second propagation

DetectionSmartsheet notifies Stacksync of record changes through webhook events. Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes.

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

Rate-limit considerations

  • ConnectWise: Subject to the platform's API rate limits per company and integration.
  • Smartsheet: 300 requests per minute per access token; heavy calls like posting attachments cost 10x (30/min). A 429 returns errorCode 4003, back off ~60s.
