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
- Write plan changes initiated in an internal admin tool back into Chargebee subscriptions.
- Mirror customers and subscriptions into Postgres so product code can check entitlement without calling the billing API.
- Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value
- Escalate conversation-derived signals into the CRM as tasks or opportunities
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.

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 Credit notes and Items and item prices), 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.
