Amazon Seller Central and Seko
Integration Agency & Consultants
Fulfilment lag and inventory overselling usually become visible the moment Amazon sales volume outpaces manual data entry. When Seller Central stock levels drift from actual Seko warehouse availability, the resulting cancellations directly impact seller ratings and account health. We connect Amazon Seller Central and Seko to ensure inventory stays in step and orders move to the warehouse without manual intervention, protecting the marketplace metrics that drive growth.
Auditing marketplace health and inventory gaps
We connect your Amazon Seller Central and Seko integrations quickly, supporting Marketplaces and WMS/3PL connections for efficient operations. Our consulting services are valuable because our system audit services uncover inefficiencies and integration gaps across Amazon Seller Central, Seko, Marketplaces, and WMS/3PL. This enables our consultants and your team to take decisive action, ensuring your technology ecosystem runs smoothly and efficiently. As a result, you can deliver a consistently excellent experience to your customers.
Solution Design
For Amazon Seller Central and Seko, the design prioritises protecting marketplace health by treating Amazon as the sales channel and Seko as the fulfilment authority. We typically configure inventory flows that protect against overselling during high-volume events. A critical design decision involves order sequencing: the integration filters for 'Unshipped' statuses, intentionally ignoring 'Pending' orders until payment verification is complete in Amazon Seller Central. The trade-off is a slight delay in warehouse visibility for the sake of data integrity and preventing premature dispatch. We also prioritise mapping order identifiers from Amazon into Seko from launch. This ensures finance can close the loop on returns and reconciliation, while operations work from Seko dispatch data, avoiding the manual work caused by mismatched references.
Mapping order flow and dispatch cycles
The integration establishes Amazon Seller Central as the order source and Seko as the fulfilment authority. Orders flow into Seko once they move from 'Pending' to 'Unshipped' status, a gate that ensures payment verification is complete. A key operational requirement is mapping Amazon's specific service levels to Seko's shipping services to avoid latency violations. Once Seko confirms a shipment, it returns tracking data which the integration writes back to Amazon to notify the customer. Inventory syncs are managed to ensure that stock levels on Amazon reflect physical availability in Seko, protecting against overselling on the marketplace. By monitoring each transfer point for SKU mismatches and reference gaps, the integration identifies issues before they impact dispatch windows, maintaining a consistent data loop between the marketplace and the warehouse.
Secure orchestration for scaling order volumes
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations enables secure, efficient integration between Amazon Seller Central, Seko, Marketplaces, and WMS/3PL systems. This approach simplifies connecting Amazon Seller Central and Seko to Marketplaces and WMS/3PL, ensuring data protection and compliance. IPaaS platforms reduce manual effort, improve reliability, and support business growth, while maintaining security as a minimum requirement.
Surfacing exceptions before they impact ratings
Visibility goes beyond checking if a sync is active. Hidden issues, such as address format errors or SKUs that exist on Amazon but haven't been mapped in Seko, can cause fulfilment delays if left undetected. Our approach surfaces these operational exceptions before they impact your seller rating. We monitor the flow of data to highlight where orders are stuck or where inventory levels no longer match between systems. This allows your team to manage by exception, focusing only on the specific records that require intervention to keep the fulfilment process moving.
Handover for internal operations and ecommerce
Post-launch, ownership transitions to your internal operations and ecommerce teams. Operations typically manage the Seko fulfilment process, while ecommerce monitors Amazon Seller Central for channel-specific alerts. We hand over an operating model that defines how data moves and what your team should check daily to ensure orders are flowing. Documentation is provided as an operational reference for the business team rather than a technical manual. It explains how to interpret alerts from the integration layer and defines who owns each exception type, such as address validation errors or SKU mismatches. This ensures your team can manage the day-to-day integration without relying on technical support for routine data issues.
Post-live monitoring of fulfilment stabililty
Support is focused on maintaining the stability of your warehouse and marketplace connection. After your integration is live, we monitor the data flows for exceptions, such as failed tracking updates, that could affect your performance ratings. When issues arise, we provide a clear path to resolve errors before they impact the fulfilment process. This includes monitoring the integration to ensure it continues to support your order volume as your business grows. We focus on keeping the connection between Amazon and Seko stable, allowing your operations team to stay focused on fulfilment rather than troubleshooting data issues.
Common failures
High-velocity inventory overselling\nDuring events like Amazon Lightning Deals, the delay between a sale and a stock update can cause overselling. If inventory syncs default to daily snapshots, the lag is too great for marketplace volume. This results in cancelled orders and direct risk to Amazon account health. We mitigate this by enabling more frequent inventory pushes to ensure the quantity in Amazon remains accurate.\n\n
Service level mapping failures\nIf specific Amazon flags like 'IsPrime' are not explicitly mapped to individual Seko service levels, Seko may default to standard economy processing. This causes shipping latency violations in Seller Central, potentially losing the Prime badge or triggering account suspension. The integration must translate Amazon service requirements into carrier instructions Seko understands to protect dispatch timeliness.\n\n
Return reconciliation gaps\nFailing to map the Amazon 'MerchantOrderID' to the Seko 'ClientReference' field makes reconciling customer returns difficult. Seko often defaults to its internal reference on return receipts, which does not exist in Amazon. This creates reconciliation debt for the finance team, who must then manually trace return records back to original orders to process refunds in Seller Central.
Frequently asked questions
How does this integration prevent overselling on Amazon as our order volume grows?
The integration treats Seko as the source of truth for physical stock, updating inventory levels in Amazon Seller Central after a Sales Order is processed for despatch. When Seko confirms stock is allocated, the available quantity is adjusted on the corresponding Amazon SKU. This ensures your listings reflect what is actually available to ship, protecting your seller rating from the impact of stockouts.
What happens if the Amazon order number doesn't map correctly into Seko?
If the Amazon 'MerchantOrderID' fails to map to Seko's 'ClientReference' field, your customer service team cannot trace an order from one system to the other. This makes handling queries about despatch status very difficult and slows down order-to-cash reconciliation. Without this shared reference, associating a shipment from Seko with the original Amazon Sales Order becomes a manual, error-prone task.
How does shipment and tracking information get from Seko back to Amazon?
Seko transmits a shipment confirmation containing the tracking number and carrier, which the integration uses to update the original order in Amazon Seller Central. This automatically marks the order as shipped and provides the tracking information to the end customer. Completing this step promptly is critical, as Amazon requires tracking data to be uploaded before the 'Ship By' date to avoid late-dispatch penalties.
We are growing quickly. When should we move from manual order entry to an integration?
An integration becomes essential when your Amazon sales growth causes fulfilment delays and inventory errors that start to affect your seller rating. If your operations team is manually re-keying Amazon sales orders into Seko, you will reach a volume where costly mistakes are unavoidable. These errors directly impact your dispatch times and stock accuracy, the two most important factors for maintaining a healthy Amazon merchant account.
Can special characters in Amazon customer addresses cause orders to fail in Seko?
Yes, this is a common failure where an order from Amazon Seller Central does not correctly load into Seko. If the customer's address contains non-alphanumeric characters that Seko's system cannot process, the Sales Order will fail to inject and halt the fulfilment process. This creates an operational delay and requires your team to manually find and clean the data before the order can be picked.
