Why teams connect Kommo and Smartsheet

Sync what happens in Smartsheet with the customer records in Kommo, in real time and in both directions.

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 Smartsheet 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 Attachments, Discussions and Comments, Users and Groups, Sheets in Smartsheet to Companies, Pipelines & Statuses, Tasks, Notes in Kommo with bi-directional, real-time sync. Activity and record changes in Smartsheet update the matching contact or account in Kommo, and CRM data flows the other way wherever Smartsheet can store and use it.

Common use cases

  • 01 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
  • 02 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.
  • 03 Replicate Kommo leads and contacts into a database or warehouse for reporting beyond built-in dashboards
  • 04 Push web form and product signups into Kommo pipelines as they are submitted so messenger-based follow-up starts quickly

Common sync patterns

Where Smartsheet can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Kommo sync into Smartsheet, so people working there have the context without switching tools.

Where Smartsheet supplies contact or company data

Enriched fields land directly on records in Kommo, and refreshes keep them from going stale.

What you can sync between Kommo 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.

Kommo objects Smartsheet objects How this pairing syncs
Leads The central pipeline record; external signups and form fills sync in as leads. Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. Leads is specific to Kommo and Users and Groups to Smartsheet — each maps to any object or custom field on the other side.
Contacts Person records sync with other CRMs and databases for a shared contact file. 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. Contacts is specific to Kommo and Sheets to Smartsheet — each maps to any object or custom field on the other side.
Companies Organization records map to accounts in ERPs and invoicing tools. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Companies is specific to Kommo and Rows to Smartsheet — each maps to any object or custom field on the other side.
Pipelines & Statuses Stage definitions structure lead progress and drive stage-change syncs to reporting tools. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Pipelines & Statuses is specific to Kommo and Columns to Smartsheet — each maps to any object or custom field on the other side.
Tasks Follow-up records keep rep activity consistent across systems. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. Tasks is specific to Kommo and Cells to Smartsheet — each maps to any object or custom field on the other side.
Notes Free-text and system notes attach context to synced leads and contacts. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Notes is specific to Kommo and Reports to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between Kommo 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.

Kommo Smartsheet Sub-second propagation

DetectionKommo notifies Stacksync of record changes through webhook events. Webhooks on record add and update events, plus polling for backfill.

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

Smartsheet Kommo 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 Kommo through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Kommo: Subject to per-account request rate limits.
  • 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.
