Two-way sync
Changes in Insightly or Streak CRM instantly reflect in both systems. No stale data, no manual imports.
Keep Insightly and Streak CRM in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.
Stacksync syncs Leads, Opportunities, Projects, Tasks in Insightly with Organizations, Tasks, Email threads, Custom fields in Streak CRM in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.
Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
Deal stage and value on shared accounts stay visible from either CRM.
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
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.
| Insightly objects | Streak CRM objects | How this pairing syncs | |
|---|---|---|---|
| Contacts Person records sync with marketing and support tools to keep one contact list. | Contacts People linked to boxes, synced with marketing and support tools. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Organizations Company records map to accounts in ERPs and other CRMs. | Organizations Company records associated with contacts and boxes. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Tasks Activity records keep follow-ups consistent across systems. | Tasks To-dos attached to boxes for follow-up tracking. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Custom Fields Per-object custom fields carry enrichment and billing data written from external systems. | Custom fields Per-pipeline field definitions that determine what data a box can hold. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Events Calendar items sync for a complete activity timeline. | Pipelines Define the process and the custom field schema that boxes in them carry. | Events is specific to Insightly and Pipelines to Streak CRM — each maps to any object or custom field on the other side. | |
| Notes Free-text context attaches to synced records for downstream visibility. | Boxes The core record (a deal, hire, or project) tracked through pipeline stages. | Notes is specific to Insightly and Boxes to Streak CRM — each maps to any object or custom field on the other side. |
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.
