Why teams connect Lemlist and Sage Intacct

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

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Leads, Activities, Unsubscribes, Webhooks in Lemlist with AR Invoices, AP Bills, Payments, Order Entry Transactions in Sage Intacct 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

  • Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
  • Keep project and department dimensions aligned with a PSA or HRIS so coding stays consistent across systems.
  • Create AR invoices or Order Entry transactions from subscription and order data held in a Postgres application database.

Where Sage Intacct is the HR or people system of record

Worker and organization data from Sage Intacct stays current in Lemlist, 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 Lemlist faces customers and Sage Intacct carries account records

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

What you can sync between Lemlist and Sage Intacct

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.

Lemlist objects Sage Intacct objects
Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Journal Entries GL activity written from external systems and replicated to warehouses.
Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Customers AR masters synced bi-directionally with CRMs like Salesforce and HubSpot.
