With our expertise, you can deliver a reliable customer experience and keep your business running smoothly as you grow.
Solution Design
This architecture defines Fulfil as the master for financial transactions and item data while Seko manages physical operations. We typically design order transmission to be frequent to minimise picker idle time, while balancing inventory update cadences to protect system stability. This ensures Fulfil remains accurate without being overwhelmed by high-volume physical arrivals or picks. A core design decision involves how partial shipments are recorded; in most setups, each Seko shipment notification updates specific records in Fulfil to maintain inventory truth. This design ensures finance can perform reconciliations based on verified shipping data in Fulfil, while the warehouse team works from the physical truth in Seko. Source-of-truth boundaries are clearly defined to ensure both systems remain in sync during high-volume periods.
Managing order flow and shipment feedback loops
This integration establishes Fulfil as the master for order creation and Seko as the authority for physical fulfilment. Validated orders flow from Fulfil to Seko on a defined schedule, carrying SKU details and shipping requirements. Once the warehouse confirms a pick, shipment data and tracking numbers flow back to Fulfil to trigger status updates and financial records. We prioritise the timing of these updates to prevent stock discrepancies. If a shipment fails to post back from Seko, the issue is surfaced early to prevent shipping delays or inventory drift. This feedback loop ensures that inventory truth in Fulfil remains anchored to physical movements in the warehouse, protecting the business against overselling during peak volume or promotional periods.
Orchestrating the stack via IPaaS architecture
Cogent2 uses IPaaS to streamline integration between Fulfil and Seko, enhancing data flow and operational efficiency. IPaaS offers benefits like reduced integration time, improved scalability, seamless connectivity, and real-time data synchronization, enabling businesses to focus on core activities while ensuring robust and flexible integration solutions.
Monitoring exceptions to prevent inventory drift
Standard dashboards often hide the quiet failures that erode operational trust, such as SKU mismatches that prevent an order reaching the warehouse. Our approach focuses on surfacing these exceptions early. The integration layer monitors for stuck orders, failed inventory syncs and unmapped shipping codes that would otherwise require manual discovery. Instead of hunting for errors at the end of the month, your operations team can see exactly where a sync has failed between Fulfil and Seko. This visibility ensures that problems are resolved quickly, preventing the compounding data debt that leads to incorrect financial reporting.
Operational handover for finance and logistics teams
Handover is designed for the finance and operations teams who manage the daily data flow between Fulfil and Seko. We provide an operating model that details exactly where order, inventory and shipment data live. Teams learn to check order statuses and perform periodic reconciliations between Seko physical stock and Fulfil inventory levels. Training includes how to read alerts from the integration layer to identify why a specific order may not have reached the warehouse correctly. All documentation is operational, focusing on who owns specific exception types, such as SKU mismatches or address errors. This ensures your team can resolve daily issues and maintain data integrity across both systems.
Post-launch governance and proactive error resolution
Post-launch support focuses on ongoing operational ownership and proactive monitoring of the integration health. We monitor for data exceptions between Fulfil and Seko, such as orders that have failed to transmit or inventory adjustments that have not synchronised. Our support model ensures that fulfilment-critical issues are identified and resolved, minimising potential downtime in the warehouse. This is not just technical maintenance; it is an ongoing service to ensure your financial and physical systems remain aligned as your transaction volumes grow.
Common failures
Inventory latency and overselling
Operational impact: When inventory updates from Seko are slow to reach Fulfil, the stock levels available to sell become inaccurate. During peak trading, this leads directly to overselling, forcing the customer service team to cancel orders and the finance team to process unplanned refunds. This erodes customer trust and directly impacts revenue.
Prevention / Action: The integration's design must prioritise inventory updates from Seko. This involves processing adjustments via a high-priority queue, using webhooks or frequent polling instead of slow batch files. Align with merchandising and operations teams on implementing SKU-level stock buffers in Fulfil as a conscious trade-off to mitigate overselling risk.
Mismatched fulfilment status and tracking data
Operational impact: Seko sends shipment confirmations to trigger the Item Fulfilment in Fulfil. If this data is incomplete, missing a tracking number, or uses a carrier name that Fulfil cannot recognise, the process fails. This leaves orders in an unfulfilled state, delays dispatch notifications to customers, and increases 'where is my order?' queries for the CX team.
Prevention / Action: Define a strict data contract for the shipment confirmation message, making key fields like tracking number and carrier mandatory. The integration logic should validate this data before attempting to create the Item Fulfilment record. An exception handling process should push any failures into a dedicated queue for operational review and correction.
Product master data mismatches
Operational impact: Fulfil acts as the master for product data. If a new SKU is created in Fulfil but the sync to Seko fails or is delayed, Seko's system will reject incoming Sales Orders containing that product. This blocks the entire order from being fulfilled, creating an error queue that requires manual data correction by the ecommerce or operations team to get the order moving again.
Prevention / Action: Treat master data synchronisation as a critical dependency for order flow. The integration should validate that all SKUs on an order are confirmed as active in Seko before the order is released. Monitor and alert on SKU sync failures between Fulfil and Seko so that the data can be fixed before it impacts fulfilment.
Incomplete order data for international shipments
Operational impact: International orders require complete customs data, including item value, country of origin, and HS codes, which are stored in Fulfil. If the integration does not pass this full dataset with the order to Seko, the warehouse cannot produce the correct commercial invoice. This puts the shipment on hold, creating delays and risking customs exceptions that damage the customer experience.
Prevention / Action: The implementation must include comprehensive field mapping for all required customs data from the Fulfil Item records to the Seko order payload. Before transmitting an order, the integration should run a validation check to confirm these fields are populated for international destinations. Orders failing this check should be flagged in Fulfil for correction, not silently failed in the integration layer.
Frequently asked questions
What triggers the need for a direct Fulfil to Seko integration?
Brands typically seek this integration when manual processes for sending Sales Orders and updating inventory fail under pressure, often during peak sales periods. The trigger is usually when reconciliation gaps between Fulfil's inventory records and Seko's physical stock cause overselling. This creates customer service issues and erodes trust in the financial reporting from Fulfil.
How do we maintain a single source of truth for inventory between Fulfil and Seko?
In this operating model, Fulfil is the system of record for the master Item record and available inventory levels. When Seko ships an order or receives new stock, it transmits an inventory adjustment that updates the master SKU record in Fulfil. This prevents overselling by ensuring all sales channels see an accurate view of physical stock held at Seko.
We sell product bundles. How does the integration handle these?
For the integration to work correctly, any bundled SKU sent from Fulfil must be pre-defined within Seko's system as a valid kit. If Fulfil sends a Sales Order containing a bundle that Seko does not recognise, Seko's platform will typically reject the order, causing a fulfilment delay. This requires careful data setup, ensuring commercial bundles in Fulfil are mirrored as operational kits in Seko.
Can our product SKU format cause order processing to fail?
Yes, this is a common point of failure. Seko's platform often has specific validation rules for SKU codes, such as character limits or restrictions on special characters. If an Item record in Fulfil uses a SKU that Seko's system rejects, the Sales Order will fail to import, halting the pick, pack, and ship process until the data is corrected in Fulfil.
How does the integration handle partial shipments or split orders?
The integration logic typically waits for all parts of a Sales Order to be dispatched from Seko before creating the final Item Fulfilment record in Fulfil. This prevents premature financial posting or incorrect customer notifications for an order that is not yet complete. While Seko may ship items separately, Fulfil is updated to reflect the final, consolidated shipment status, keeping the order-to-cash process accurate.
