Why teams connect Lemlist and NetSuite

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

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Lemlist 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Unsubscribes, Webhooks, Team Members, Campaigns in Lemlist with Subsidiary, All custom objects, Nexus, Tax Type in NetSuite 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

  • Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
  • Stop or pause sequences automatically when a reply converts to a deal in the CRM
  • Mirror journal entries and transaction lines into a warehouse for financial reporting without CSV exports.
  • Sync customers, sales orders, and invoices to an operational Postgres database so teams query ERP data without writing SuiteScript.

Master data corrections travel

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

Where Lemlist faces customers and NetSuite carries account records

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

Where NetSuite is the HR or people system of record

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