Why teams connect Kustomer and Stripe

Sync customers, invoices, and payment status between Stripe 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. Stripe 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 Invoices, Subscriptions, Products, Prices in Stripe to Customers, Conversations, Messages, Companies 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 customer detail updates from internal tools back to Stripe so billing records stay current
  • Sync customers, subscriptions, and payment status into the CRM so sales and support see billing state on the account record
  • Escalate conversation-derived signals into the CRM as tasks or opportunities
  • Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline

Where Kustomer tracks deals: closed-won creates the finance record

A won opportunity creates or updates the customer in Stripe with the right billing details, so invoicing starts without re-keying.

Payment status on the account

Invoice and payment status from Stripe 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, Stripe gets the update before the next invoice goes out.

What you can sync between Kustomer and Stripe

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 Stripe objects
Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. Prices Amounts and billing intervals attached to products.
Conversations Support threads across channels sync outward for analytics and CRM context. Refunds Reversals synced into finance systems for accurate revenue reporting.
Messages Individual messages within conversations support full-thread replication. Disputes Chargebacks that support and finance teams track in their own tools.
Companies Organization records group customers and map to CRM accounts. Payouts Bank transfers reconciled against balance transactions during close.
Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. Balance Transactions The ledger entries behind every money movement, the basis for reconciliation.
Users Agent records map conversation ownership to people in other systems. Events The change log; each state change is an Event retrievable via the API.
