Why teams connect Front and Kustomer

Sync what happens in Front with the customer records in Kustomer, 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 Front 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 Teammates, Channels, Conversations, Messages in Front to Tags, Notes, Customers, Conversations in Kustomer with bi-directional, real-time sync. Activity and record changes in Front update the matching contact or account in Kustomer, and CRM data flows the other way wherever Front can store and use it.

Common use cases

  • Feed CSAT and SLA reporting from synced conversation events rather than manual exports.
  • Sync conversations, messages, and tags into Postgres for response-time and volume analytics across inboxes.
  • Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value

Where Front can store CRM context: fields kept current

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

Where Front handles support or shared inboxes

Tickets and conversations attach to the right contact and account in Kustomer, so sales sees open issues before the next call.

Where Front supplies contact or company data

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

What you can sync between Front and Kustomer

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.

Front objects Kustomer objects
Channels Connected addresses (email, SMS, chat); define where messages originate and send from. Notes Internal annotations carry context alongside synced conversations.
Conversations The central threaded unit that messages, comments, and tags attach to; synced for support analytics. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it.
Messages Inbound and outbound emails, chats, and SMS within a conversation; read out for response-time reporting. Conversations Support threads across channels sync outward for analytics and CRM context.
Comments Internal team notes on conversations; usually read-only in syncs. Messages Individual messages within conversations support full-thread replication.
Contacts People across channels; matched to CRM contacts, with custom fields carrying external context. Companies Organization records group customers and map to CRM accounts.
Accounts Company groupings of contacts; kept aligned with CRM accounts. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline.
