Why teams connect Hyperline and Resend

Connect the financial records in Hyperline with the work happening in Resend, 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. Resend 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 Credit notes, Customers, Subscriptions, Products / prices in Hyperline and Broadcasts, Domains, Email events, API keys in Resend in sync, bi-directionally and in real time. Whatever records Resend 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.
  • Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.

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

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

Where Resend handles customer conversations: billing context in view

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