Why teams connect Acumatica and Lemlist

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

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Activities, Unsubscribes, Webhooks, Team Members in Lemlist with Sales Orders, Invoices, Purchase Orders, Stock Items in Acumatica 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

  • Mirror campaign performance data into BI tools for outbound reporting across senders
  • Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
  • Align Acumatica's built-in CRM opportunities and cases with an external sales or support platform.
  • Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.

Where Acumatica is the HR or people system of record

Worker and organization data from Acumatica 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 Acumatica carries account records

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