Why teams connect Customer.io and Hyperline

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

Hyperline holds the financial truth: who the customers are, what they were billed, what they paid. Customer.io 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 Payments, Billable events, Credit notes, Customers in Hyperline and Segments, Campaigns, Broadcasts, Deliveries / Messages in Customer.io in sync, bi-directionally and in real time. Whatever records Customer.io keeps and whatever events it produces, the overlap with Hyperline 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 metered usage events from a product database into Hyperline to drive usage-based invoicing.
  • Sync invoices and payments into a data warehouse or accounting system for revenue reporting and reconciliation.
  • Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.

Where Customer.io collects payments or triggers charges: events land in Hyperline

Payment and charge activity flows into Hyperline as it happens, so the books reflect reality without manual reconciliation.

Where Customer.io 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 Customer.io is a docs or knowledge workspace: reference data kept fresh

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