Why teams connect Klaviyo and Stripe
Connect the financial records in Stripe with the work happening in Klaviyo, so both stay current without exports or copy-paste.
Stripe 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 Disputes, Payouts, Balance Transactions, Events in Stripe and Tags, Profiles, Lists, Segments in Klaviyo in sync, bi-directionally and in real time. Whatever records Klaviyo keeps and whatever events it produces, the overlap with Stripe 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
- Reconcile invoices, payouts, and balance transactions into a warehouse or ERP for month-end close
- Keep the product and price catalog aligned between Stripe and an internal database that other systems read
- Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
- Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
Where Klaviyo handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Stripe next to the customer they are helping, without logging into the finance system.
Where Klaviyo collects payments or triggers charges: events land in Stripe
Payment and charge activity flows into Stripe as it happens, so the books reflect reality without manual reconciliation.
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.
What you can sync between Klaviyo 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.
| Klaviyo objects | Stripe objects | |
|---|---|---|
| Templates Message templates are accessible via API for content management workflows. | PaymentIntents The lifecycle record of a payment attempt, from creation to success or failure. | |
| Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. | Charges Individual captured payments underlying intents, used in reconciliation. | |
| Tags Organizational labels on campaigns, flows, and lists support reporting rollups. | Invoices Billing documents with line items, synced to ERPs and accounting systems. | |
| Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. | Subscriptions Recurring billing state that drives provisioning and CRM lifecycle stages. | |
| Lists Static audience memberships sync in from CRMs and forms for targeting. | Products Catalog entries kept aligned with internal product databases. | |
| Segments Dynamic audiences are readable so other tools can mirror who qualifies. | Prices Amounts and billing intervals attached to products. |

FAQ
Klaviyo and Stripe integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Klaviyo and Stripe: authenticate both systems, choose the objects to sync (such as Klaviyo's Templates and Catalog Items), 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.

Authentication: API keys (secret and restricted keys); OAuth 2.0 for Stripe Connect platforms. Stacksync manages authentication, retries, and rate limits on both sides.
-
Stripe: Related records can be expanded inline with the expand parameter, cutting the number of requests a sync needs. Klaviyo: Klaviyo's current APIs follow the JSON:API specification, so payloads use typed resource objects with relationships rather than flat JSON. Stacksync's field mapping accounts for these differences between Klaviyo and Stripe without custom code.
