Why teams connect Lemlist and Sage 100

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Lemlist and Sage 100.

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Campaigns, Leads, Activities, Unsubscribes in Lemlist with Purchase Orders, GL Accounts, Journal Entries, Customers in Sage 100 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
  • Publish item, pricing, and on-hand inventory to online catalogs on a schedule.
  • Replicate GL and sales history to a warehouse or Postgres database for reporting off the on-premise system.

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 100 carries account records

Where Sage 100 is the HR or people system of record

Worker and organization data from Sage 100 stays current in Lemlist, so the tools people use daily reflect the org as it actually is.
