Why teams connect Klaviyo and Servicemax

Stop re-entering the same information in Klaviyo and Servicemax: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Metrics, Campaigns, Flows, Templates in Klaviyo with Accounts, Contacts, Cases, Products in Servicemax in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • 01 Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • 02 Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • 03 Consolidate Service Contracts and entitlement data into a warehouse for renewal forecasting and SLA compliance dashboards.
  • 04 Mirror Accounts and Contacts between ServiceMax and the CRM system of record so customer and site data stays consistent.

Common sync patterns

Where Servicemax is where the team documents or plans: keep its data fed

Information that originates in Klaviyo stays current in Servicemax instead of going stale after a one-time paste.

Handoffs between teams

When work started in one tool continues in the other, the shared fields travel with it automatically.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

What you can sync between Klaviyo and Servicemax

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 Servicemax objects How this pairing syncs
Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. Work Orders SVMXC__Service_Order__c; the core field-service job record for install, repair, and maintenance; synced two-way with databases and pushed to ERPs at close. Events is specific to Klaviyo and Work Orders to Servicemax — each maps to any object or custom field on the other side.
Metrics Event type definitions organize the activity stream used in segmentation and attribution. Work Details SVMXC__Service_Order_Line__c; line items on a Work Order for labor, parts used, and expenses; read out for billing or written back with usage. Metrics is specific to Klaviyo and Work Details to Servicemax — each maps to any object or custom field on the other side.
Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Installed Products SVMXC__Installed_Product__c; the installed-base asset record driving entitlement and service history; synced with asset and IoT databases. Campaigns is specific to Klaviyo and Installed Products to Servicemax — each maps to any object or custom field on the other side.
Flows Automation definitions and their engagement data sync outward for attribution. Service Contracts SVMXC__Service_Contract__c; coverage and entitlement agreements; synced to warehouses for renewal, SLA, and warranty reporting. Flows is specific to Klaviyo and Service Contracts to Servicemax — each maps to any object or custom field on the other side.
Templates Message templates are accessible via API for content management workflows. Stock History SVMXC__Stock_History__c; append-only log of inventory transactions (RMA, shipment, parts receipt); read out for parts and inventory analytics. Templates is specific to Klaviyo and Stock History to Servicemax — each maps to any object or custom field on the other side.
Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. Accounts Standard Salesforce Account; customer and site company records; synced two-way with CRM and database customer tables. Catalog Items is specific to Klaviyo and Accounts to Servicemax — each maps to any object or custom field on the other side.

How changes propagate between Klaviyo and Servicemax

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Klaviyo Servicemax Sub-second propagation

DetectionKlaviyo notifies Stacksync of record changes through webhook events. Polling on updated timestamps.

DeliveryEach detected change is written to Servicemax through its API, with automatic retries and rate-limit backoff.

Servicemax Klaviyo Sub-second propagation

DetectionChanges in Servicemax are captured at the source via change data capture — no polling loop against its API. Salesforce mechanisms — Apex triggers or polling on SystemModstamp/LastModifiedDate, with Change Data Capture / Platform Events available per object.

DeliveryEach detected change is written to Klaviyo through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Klaviyo: Per-endpoint burst and steady rate limits apply.
  • Servicemax: Governed by the Salesforce org-wide daily API request allocation, shared across all integrations and scaled by edition and license count.
