Why teams connect Chargebee and Klaviyo

Connect the financial records in Chargebee with the work happening in Klaviyo, so both stay current without exports or copy-paste.

Chargebee holds the financial truth: who the customers are, what they were billed, what they paid. Klaviyo is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.

Stacksync keeps Items and item prices, Payment sources, Transactions, Coupons in Chargebee and Segments, Events, Metrics, Campaigns in Klaviyo in sync, bi-directionally and in real time. Whatever records Klaviyo keeps and whatever events it produces, the overlap with Chargebee is mapped field by field, and a change on either side shows up on the other within seconds.

There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.

Common use cases

  • Push invoices and credit notes into an accounting system or warehouse for revenue reporting.
  • Write plan changes initiated in an internal admin tool back into Chargebee subscriptions.
  • Sync customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows

Where Klaviyo tracks people or companies: one identity

A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.

Where Klaviyo is a docs or knowledge workspace: reference data kept fresh

Figures teams rely on, like customer status or outstanding balances, stay current wherever Klaviyo surfaces them instead of going stale after a one-time paste.

Where Klaviyo handles customer conversations: billing context in view

Front-line teams see invoice and payment status from Chargebee next to the customer they are helping, without logging into the finance system.

What you can sync between Chargebee and Klaviyo

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 Klaviyo objects
Credit notes Adjustments and refund documents needed for accurate revenue reconciliation. Lists Static audience memberships sync in from CRMs and forms for targeting.
Items and item prices The product catalog (plans, addons, charges) referenced by every subscription. Segments Dynamic audiences are readable so other tools can mirror who qualifies.
Payment sources Stored payment methods; usually read-only metadata in syncs for compliance reasons. Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows.
Transactions Payment attempts and outcomes synced for dunning and finance workflows. Metrics Event type definitions organize the activity stream used in segmentation and attribution.
Coupons Discount definitions and redemptions used in deal-desk and reporting syncs. Campaigns Email and SMS sends expose performance data for warehouse-based reporting.
Events The change log resource that records every state change for incremental sync. Flows Automation definitions and their engagement data sync outward for attribution.
