Two-way sync
Changes in Kustomer or Vtiger CRM instantly reflect in both systems. No stale data, no manual imports.
Keep Kustomer and Vtiger 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 Conversations, Messages, Companies, Custom Objects (Klasses) in Kustomer with Organizations, Leads, Opportunities, Cases in Vtiger 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.
| Kustomer objects | Vtiger CRM objects | |
|---|---|---|
| Users Agent records map conversation ownership to people in other systems. | Sales Orders Order records between quote and invoice, synced to fulfillment systems. | |
| Teams Team assignments support routing parity and reporting. | Invoices Billing documents pushed into accounting software. | |
| Tags Labels on conversations and customers sync for categorization and analytics. | Campaigns Marketing campaign records tied to leads and contacts. | |
| Notes Internal annotations carry context alongside synced conversations. | Contacts Person records linked to organizations; a core target for two-way contact syncs. | |
| Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | Organizations Company and account records. | |
| Conversations Support threads across channels sync outward for analytics and CRM context. | Leads Unqualified prospects that convert into contacts, organizations, and opportunities. |
