Cin7 Core and Klaviyo
Integration Agency & Consultants
At scale, the gap between what Cin7 Core knows about inventory and what Klaviyo tells customers becomes a liability. This usually becomes painful when marketing triggers emails for items already committed to other sales orders. We connect Cin7 Core to Klaviyo so your team can segment by real customer value and available-to-sell figures. This ensures marketing stays in step with the ERP, protecting your margin and customer trust by ensuring the team only promotes stock the business can actually fulfil.
Establishing the source of truth diagnosis
Before technical work begins, we diagnose the data relationship between Cin7 Core and Klaviyo. This discovery stage examines the source of truth for customer records, how stock-outs are currently handled, and where data contradictions exist between systems. We determine how inventory availability should be calculated to prevent Klaviyo from promoting out-of-stock items. Consulting defines the operating model upfront, deciding how data flows between the ERP and the marketing platform to drive revenue. Robust design at this stage avoids the risk of irrelevant messaging and prevents the need for manual data corrections after go-live.
Solution Design
Designing for Cin7 Core and Klaviyo requires an opinionated stance on data ownership. We establish Cin7 Core as the authority for transactional data and available inventory, syncing these as events to Klaviyo. A primary design decision involves the trade-off between sync frequency and system performance. While high-frequency updates provide better accuracy for 'back in stock' flows, they can lead to sync delays during peak traffic. We typically sequence the core order flow first, ensuring transaction history is reconciled before building complex segments. This design ensures marketing flows are driven by real-world availability, helping the brand avoid promoting stock already committed to other orders. The operating model ensures marketing teams act on data owned by the ERP.
Synchronising stock availability with marketing events
Cin7 Core acts as the inventory and transaction master, pushing order history and stock status to Klaviyo to drive event-based flows. To prevent overselling, we sync available-to-sell figures rather than raw stock on hand, accounting for inventory already committed to other orders. We establish clear ownership boundaries for customer records and returns, ensuring that when a Credit Note is finalised in Cin7 Core, the corresponding refund value is reflected in Klaviyo to maintain accurate customer segments. Monitoring is embedded to detect sync stalls during high-traffic periods, ensuring marketing data remains trustworthy.
Orchestrating resilient inventory and order syncs
A controlled integration layer governs the flow of orders, inventory updates, and customer metrics between Cin7 Core and Klaviyo. This layer ensures that marketing events are grounded in ERP reality. We account for failure scenarios, such as data mismatches, that could otherwise break automated marketing flows. Each data sync is validated, with logging and alerting in place to catch errors early. This governance prevents marketing triggers from firing based on inaccurate data. The infrastructure adheres to high security standards and is actively managed to ensure consistent performance between the ERP and the marketing platform.
Identifying operational drift and sync stalls
Standard dashboards often hide the quiet failures that degrade marketing performance. Visibility in this integration means knowing exactly when the inventory record in Cin7 Core deviates from the trigger threshold in Klaviyo. This often manifests as operational drift where marketing flows promote SKUs that Cin7 Core has already committed to wholesale orders. We surface these stalls and data fragments before they result in irrelevant customer communications. By monitoring the boundary between ERP and marketing events, we identify when a sale in Cin7 Core fails to update a Klaviyo segment, preventing revenue leakage and ensuring marketing reflects actual stock availability.
Managing system ownership and data integrity
Handover ensures the ecommerce, marketing, and operations teams own the integrated model. We define how marketing reads available-to-sell triggers and how ecommerce monitors the flow of order history into Klaviyo segments. Your team is taught what to check weekly to maintain data integrity, how to interpret sync alerts, and who owns exceptions like duplicate order events. Documentation is strictly operational, written for the people running the business rather than a technical reference. This ensures the marketing team builds flows based on real inventory availability without constant developer support, preventing the promotion of stock already committed to other orders.
Maintaining data accuracy through peak traffic
Support focus is on maintaining the integrity of the data flow between Cin7 Core inventory figures and Klaviyo triggers. We monitor for sync delays during high-traffic periods, which can lead to customers receiving notifications for items that are no longer available. When exceptions occur, such as a failed order sync or data mismatch, we identify the cause and resolve it. This proactive oversight ensures that automated marketing flows remain grounded in actual ERP inventory levels, protecting the customer experience.
Common failures
Inaccurate 'back in stock' notifications
Operational impact: Marketing promotes SKUs that are unavailable, creating avoidable CX tickets. This occurs when triggers use raw stock figures rather than Cin7 Core's available-to-sell quantity, which excludes stock committed to wholesale or transfers.
Prevention: The integration maps to the 'Available' stock field, ignoring stock-on-hand figures that do not reflect true warehouse commitments.
Duplicate 'Placed Order' events
Operational impact: Customer segments and revenue attribution become inflated, leading to incorrect marketing spend. This happens when Klaviyo receives order data from both Cin7 Core and a native storefront integration simultaneously.
Prevention: We configure Cin7 Core to push only offline and B2B wholesale order data, ensuring storefront orders are not double-counted in Klaviyo.
Stale 'Voided' status in marketing flows
Operational impact: Customers with cancelled orders continue to receive automated marketing because Klaviyo still sees the order as active. Cin7 Core does not natively push 'Voided' status updates after the initial sync.
Prevention: We implement a reconciliation process to identify cancelled orders in Cin7 Core and ensure Klaviyo records are corrected, preventing flows from triggering for voided transactions.
Frequently asked questions
How do we stop Klaviyo sending 'back in stock' alerts for items reserved for wholesale orders in Cin7 Core?
The integration must be configured to use Cin7 Core's true available-to-sell quantity, not just the total stock level. This ensures stock committed to wholesale sales orders or pending branch transfers within Cin7 Core is excluded from the inventory figure pushed to Klaviyo. Without this, Klaviyo could trigger campaigns for a SKU that is technically unavailable for ecommerce customers.
Can we segment customers in Klaviyo based on their total spend from Cin7 Core?
Yes, this is a primary purpose of the integration. Historical sales order data can be synced from Cin7 Core to create or update customer profiles in Klaviyo. This allows your marketing team to build valuable segments based on properties like lifetime value and order frequency, using Cin7 Core as the financial source of truth.
Our B2B and phone orders are created directly in Cin7 Core. Can these customers be synced to Klaviyo?
Yes, the integration can be designed to capture all new and updated customer records from Cin7 Core, regardless of their origin. This ensures customers who place orders offline are still added to your Klaviyo account for marketing campaigns. This unifies your marketing audience, giving you a complete view of your customer base.
What happens if a SKU is updated in Cin7 Core? Can this break the Klaviyo sync?
Cin7 Core relies on an exact SKU match to sync inventory data, so data hygiene is critical. If a SKU is changed in Cin7 Core but not in the ecommerce platform that feeds Klaviyo, stock updates for that item will fail. Consequently, Klaviyo would operate on stale inventory data, potentially promoting out-of-stock items from its catalogue.
