Why teams connect Chargebee and Kustomer
Sync customers, invoices, and payment status between Chargebee and Kustomer in real time, so sales sees the money and finance sees the relationship.
Finance and sales describe the same customers in different systems. Kustomer knows the relationship: who the contacts are and what is in motion with the account. Chargebee knows the money: what was invoiced, what was paid, what is overdue. When the two are connected only by exports, each side works partly blind.
Stacksync links Events, Customers, Subscriptions, Invoices in Chargebee to Companies, Custom Objects (Klasses), Users, Teams in Kustomer with bi-directional, real-time sync. New customers, updated billing details, invoice status, and payment activity move in whichever direction you configure, field by field, with conflicts resolved by rules you set. The result is one version of each customer, visible from both sides.
Common use cases
- 01 Write plan changes initiated in an internal admin tool back into Chargebee subscriptions.
- 02 Mirror customers and subscriptions into Postgres so product code can check entitlement without calling the billing API.
- 03 Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
- 04 Escalate conversation-derived signals into the CRM as tasks or opportunities
Common sync patterns
Where Kustomer tracks deals: closed-won creates the finance record
A won opportunity creates or updates the customer in Chargebee with the right billing details, so invoicing starts without re-keying.
Payment status on the account
Invoice and payment status from Chargebee appears on the account in Kustomer, so reps see overdue balances before they promise the next order.
Billing detail changes flow back
When a contact or address is corrected in Kustomer, Chargebee gets the update before the next invoice goes out.
What you can sync between Chargebee 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.
| Chargebee objects | Kustomer objects | How this pairing syncs | |
|---|---|---|---|
| Customers Billing accounts matched to CRM accounts or users by email or external ID. | Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Credit notes Adjustments and refund documents needed for accurate revenue reconciliation. | Messages Individual messages within conversations support full-thread replication. | Credit notes is specific to Chargebee and Messages to Kustomer — each maps to any object or custom field on the other side. | |
| Items and item prices The product catalog (plans, addons, charges) referenced by every subscription. | Companies Organization records group customers and map to CRM accounts. | Items and item prices is specific to Chargebee and Companies to Kustomer — each maps to any object or custom field on the other side. | |
| Payment sources Stored payment methods; usually read-only metadata in syncs for compliance reasons. | Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. | Payment sources is specific to Chargebee and Custom Objects (Klasses) to Kustomer — each maps to any object or custom field on the other side. | |
| Transactions Payment attempts and outcomes synced for dunning and finance workflows. | Users Agent records map conversation ownership to people in other systems. | Transactions is specific to Chargebee and Users to Kustomer — each maps to any object or custom field on the other side. | |
| Coupons Discount definitions and redemptions used in deal-desk and reporting syncs. | Teams Team assignments support routing parity and reporting. | Coupons is specific to Chargebee and Teams to Kustomer — each maps to any object or custom field on the other side. |
How changes propagate between Chargebee 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.
Chargebee Kustomer Sub-second propagation
DetectionChargebee notifies Stacksync of record changes through webhook events. Webhooks for all major object events, plus a pollable Events resource that records every change.
DeliveryEach detected change is written to Kustomer through its API, with automatic retries and rate-limit backoff.
Kustomer Chargebee Sub-second propagation
DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.
DeliveryEach detected change is written to Chargebee through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Chargebee: Subject to plan-based API rate limits enforced per site.
- Kustomer: Subject to the platform's API rate limits.

FAQ
Chargebee and Kustomer integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Chargebee and Kustomer: authenticate both systems, choose the objects to sync (such as Chargebee's Customers and Credit notes), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Chargebee and Kustomer: Where Kustomer tracks deals: closed-won creates the finance record; Payment status on the account; Billing detail changes flow back. A won opportunity creates or updates the customer in Chargebee with the right billing details, so invoicing starts without re-keying.
-
Chargebee: REST API. Authentication: API key sent via HTTP basic authentication (key as the username), scoped per site with test and live environments. Kustomer: REST API. Authentication: API key used as a bearer token, scoped by role. Stacksync manages authentication, retries, and rate limits on both sides.
-
Chargebee: Chargebee has two product catalog versions; in the newer model plans, addons, and charges are unified as items with per-currency, per-frequency item prices, and connectors must handle whichever version a site uses. Kustomer: API keys are issued as role-scoped bearer tokens, so integration access can be limited to the specific object types a sync touches. Stacksync's field mapping accounts for these differences between Chargebee and Kustomer without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Chargebee and Kustomer records are not retained after a sync operation.
