Why teams connect Klaviyo and Syspro

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

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Klaviyo 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Events, Metrics, Campaigns, Flows in Klaviyo with Purchase orders, Jobs (work orders), Bills of materials, AR invoices in Syspro 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 offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • Extract job and WIP data into a warehouse for production and costing reports
  • Post shipment confirmations from logistics systems back against SYSPRO sales orders

Where Syspro is the HR or people system of record

Worker and organization data from Syspro stays current in Klaviyo, 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 Klaviyo faces customers and Syspro carries account records

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

What you can sync between Klaviyo and Syspro

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.

Klaviyo objects Syspro objects
Lists Static audience memberships sync in from CRMs and forms for targeting. Jobs (work orders) Manufacturing jobs and WIP tracked for production reporting.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Bills of materials Product structures referenced when syncing manufacturing data.
Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. AR invoices Billing documents surfaced to CRMs and finance reporting.
Metrics Event type definitions organize the activity stream used in segmentation and attribution. GL journals Financial postings extracted for consolidation and analytics.
Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Warehouses Stocking locations that scope inventory balances.
Flows Automation definitions and their engagement data sync outward for attribution. Customers AR customer master records matched against CRM accounts.
