Why teams connect Cin7 and Resend

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Resend and Cin7.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Resend is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Contacts, Audiences, Broadcasts, Domains in Resend with Contacts, Branches / locations, Stock adjustments and transfers, Credit notes / returns in Cin7 bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • Write purchase orders created in a planning tool back into Cin7 for receiving.
  • Consolidate stock movements from multiple branches into one reporting database.

Where Cin7 is the HR or people system of record

Worker and organization data from Cin7 stays current in Resend, so the tools people use daily reflect the org as it actually is.

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.

Where Resend faces customers and Cin7 carries account records

Order, invoice, or account status from Cin7 appears alongside the customer in Resend, so front-line teams answer from live data.
