Cin7 Core and Klaviyo
Integration Agency & Consultants
Our AI-powered delivery, guided by experienced operators, builds the critical link between operations and marketing. We connect Cin7 Core to Klaviyo so your marketing team can build segments from rich ERP data, like lifetime value. This stops campaigns from running on bad inventory data, protecting revenue and customer trust.
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
The integration establishes Cin7 Core as the master for inventory and transactions, pushing order history and stock status to Klaviyo to drive event-based flows. Data integrity is maintained by syncing available-to-sell figures rather than raw stock on hand. This ensures Klaviyo triggers only fire for truly available items. We configure the flow of customer records and order events to ensure attribution remains accurate. Timing rules are defined to prevent stock figures from drifting between platforms. Monitoring is embedded at the boundary to detect sync delays or data errors before they affect automated campaigns.
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. We surface hidden issues, such as stalled syncs or fragmented data, before they result in irrelevant customer communications. We monitor the health of automated flows to ensure that sales events are correctly reflected across both systems. By surfacing these exceptions early, we help prevent revenue leakage and protect your brand reputation by ensuring marketing stays aligned with actual stock levels that are available for new orders.
Managing system ownership and data integrity
Handover ensures ecommerce and marketing teams own the integrated model. We define how marketing reads stock triggers and how the ecommerce team monitors the flow of order history into Klaviyo segments. Your team is taught what to check on a regular schedule, how to interpret alerts from the integration layer, and who owns exceptions like sync errors or customer data mismatches. Handover documentation is strictly operational, focusing on daily management rather than technical reference. This ensures the marketing team builds flows based on real availability without constant technical support. Experience suggests ops teams typically manage inventory logic while marketing owns the segment triggers.
Maintaining data accuracy through peak traffic
Ongoing support focuses on the health of the data flow between Cin7 Core and Klaviyo. We monitor for stalls in inventory updates or mismatched order attributes that could trigger incorrect customer flows. When an exception occurs, our team identifies the root cause and handles the response. Regular updates verify segment accuracy and ensure the marketing stack stays in step with actual ERP transactions, reducing the risk of marketing out-of-stock items.
Common failures
Inaccurate 'back in stock' notifications
Operational impact: Marketing promotes SKUs that are unavailable for purchase, creating poor customer experiences and generating avoidable CX tickets. This occurs when Klaviyo's stock triggers are not based on Cin7 Core's true available-to-sell quantity, which correctly accounts for stock committed to wholesale orders or pending warehouse transfers.
Prevention / Action: The integration's logic must ensure Klaviyo's stock-level events are driven exclusively by Cin7 Core's 'Available' stock figure, not a simpler 'Stock on Hand' number. The data feed must be frequent, with robust queue management and retry logic to prevent stale data during flash sales or high-traffic periods.
Premature dispatch and fulfilment notifications
Operational impact: Customers receive shipping confirmation emails triggered by an order event, but before the items have actually been picked, packed or dispatched by the fulfilment team. This leads to an increase in 'where is my order?' support tickets, erodes customer trust, and disrupts post-purchase marketing flows that depend on accurate shipping-event triggers.
Prevention / Action: Design the integration to use a confirmed 'Shipped' status from a Cin7 Core Sales Order or its related fulfilment record as the sole trigger for dispatch-related communications in Klaviyo. Do not use the initial 'Placed Order' event to imply movement. Align operational processes so that the fulfilment team's scanner activity or end-of-day manifest directly updates the status in Cin7 Core.
Incorrect customer segmentation
Operational impact: VIP or wholesale customers are sent marketing campaigns with standard retail pricing, or are targeted with irrelevant offers, potentially damaging key business relationships. The marketing team's segmentation in Klaviyo becomes unreliable if it cannot distinguish customer tiers defined in the ERP, leading to mis-targeted campaigns and inaccurate reporting.
Prevention / Action: Establish Cin7 Core as the source of truth for customer categorisation, such as 'wholesale' or 'VIP' tiers. This status should be mapped to a dedicated, and protected, custom property on the Klaviyo customer profile. All segmentation and flow-filter logic in Klaviyo must be built to use this reliable property from Cin7 Core, not inferred from order history or other proxies.
Miscalculated customer lifetime value after returns
Operational impact: The marketing team's view of customer value in Klaviyo is inflated because it does not account for returned products. This leads to inaccurate segmentation, flawed ROI analysis for campaigns, and wasted marketing spend targeting customers based on a lifetime value they did not actually deliver.
Prevention / Action: Ensure that the integration creates a 'Refunded Order' event in Klaviyo when a Credit Note is finalised in Cin7 Core. This event should be linked to the original customer profile and order, and contain the negative value of the refund. Klaviyo's lifetime value calculations can then be configured to correctly subtract these amounts, providing a more accurate basis for segmentation and analysis.
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.
