Why teams connect BetterContact and Kustomer

Flow BetterContact data into Kustomer in real time — no exports, no schedulers, no custom scripts.

BetterContact is a read-only source: Stacksync reads its data in real time and delivers it into Kustomer, so Kustomer always reflects the current state of BetterContact — without exports, scripts, or schedulers.

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 BetterContact 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.

Common use cases

  • 01 Backfill a warehouse of contacts with waterfall enrichment across 20+ data providers.
  • 02 Feed outbound sequencing tools with verified contact data before campaigns launch.
  • 03 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
  • 04 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting

Common sync patterns

Where BetterContact runs outreach

Prospects, sends, and replies sync into Kustomer, keeping lead status current without manual imports.

Where BetterContact supplies contact or company data

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

Where BetterContact can store CRM context: fields kept current

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

What you can sync between BetterContact 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.

BetterContact objects Kustomer objects How this pairing syncs
Company Company data returned with each contact: name, domain, HQ location, industry, employee count. Companies Organization records group customers and map to CRM accounts. Same entity on both sides — records pair one-to-one and field-level changes reconcile in the writable direction. Custom fields on either side are included in the mapping.
Enrichment Request Batch or single submissions of up to 100 contacts per request for waterfall enrichment. Messages Individual messages within conversations support full-thread replication. Enrichment Request is specific to BetterContact and Messages to Kustomer — each maps to any object or custom field on the other side.
Enriched Contact Verified work emails and mobile numbers with job title, LinkedIn profile, location, and skills. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. Enriched Contact is specific to BetterContact and Custom Objects (Klasses) to Kustomer — each maps to any object or custom field on the other side.
Lead Finder Search Prospect discovery by people and company filters, returning enriched lead profiles. Users Agent records map conversation ownership to people in other systems. Lead Finder Search is specific to BetterContact and Users to Kustomer — each maps to any object or custom field on the other side.

How changes propagate between BetterContact and Kustomer

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.

BetterContact Kustomer Sub-second propagation

DetectionBetterContact notifies Stacksync of record changes through webhook events. Job-based delivery — enrichment results arrive by webhook push or polling of the results endpoint.

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

Kustomer BetterContact Sub-second propagation

DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.

DeliveryBetterContact does not accept inbound record writes, so this direction carries requests rather than records: BetterContact's output flows back as field updates on the originating Kustomer records.

Rate-limit considerations

  • BetterContact: Batches capped at 100 contacts per enrichment request.
  • Kustomer: Subject to the platform's API rate limits.
