Why teams connect Lemlist and SAP Business One

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

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 A/R Invoices, Purchase Orders, Deliveries, Journal Entries in SAP Business One 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
  • Create sales orders in Business One from e-commerce platforms and sync delivery and invoice status back to the storefront.
  • Mirror items, stock levels, and price lists to external channels so quotes and listings use current ERP data.

Where SAP Business One is the HR or people system of record

Worker and organization data from SAP Business One 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 SAP Business One carries account records

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