Scoping the ERP and marketplace audit

We connect your Fulfil and Marketplacer integrations with expert consulting, ensuring your ERP and Marketplaces work together efficiently. Our system audit services uncover inefficiencies and integration gaps between Fulfil, Marketplacer, ERP, and Marketplaces, enabling your team and our consultants to take decisive action. This approach helps your technology ecosystem run smoothly, supporting reliable operations and a great customer experience. By addressing issues early, we help you deliver consistent performance across Marketplacer and Fulfil, keeping your Marketplaces and ERP aligned with your business goals.

Solution Design

In most setups, Fulfil serves as the authoritative source for inventory truth and order fulfilment. We typically push stock levels from specific Fulfil locations to Marketplacer to ensure sellers only offer what they can physically fulfil. A core design trade-off involves sync frequency: increasing the update cadence protects against overselling but risks triggering Marketplacer API rate limits during peak trading. To manage this safely, we often implement safety stock buffers within Fulfil. We ensure partial refunds in Fulfil map to specific Marketplacer Invoice Line IDs to prevent the marketplace UI from incorrectly flagging entire orders as refunded. This architecture ensures finance teams can trust the financial postings at month-end while operations maintain accurate inventory visibility across all marketplace channels.

Data flow and SKU mapping logic

Fulfil acts as the inventory source of truth, while Marketplacer manages the customer-facing listings. Orders created in Marketplacer flow into Fulfil for processing, ensuring the warehouse team has immediate visibility of marketplace demand. Once an order is shipped in Fulfil, the tracking number and carrier details are pushed back to Marketplacer to update the order status. We focus on SKU mapping to ensure that stock levels stay synchronised across both systems. The integration includes monitoring to detect gaps, such as incorrect shipping codes or missing product data, ensuring that orders move through fulfilment without manual intervention or status lag.

Orchestrating the integration via IPaaS layer

Cogent2 uses IPaaS to streamline integration between Fulfil and Marketplacer, enhancing data flow and process automation. Benefits include reduced integration complexity, faster deployment, improved scalability, and seamless connectivity, enabling efficient management of e-commerce operations and better client service delivery.

Monitoring exceptions and tracking sync health

Operational visibility requires knowing exactly why an order has stalled between Fulfil and Marketplacer. Green-light dashboards often mask issues like unmapped shipping codes or stock level deltas. We move beyond surface metrics by surfacing specific exceptions, such as when tracking details in Fulfil fail to update the marketplace due to carrier naming mismatches. By monitoring the gap between inventory in Fulfil and active adverts in Marketplacer, you can identify and fix sync lag before it results in an oversell event. This approach ensures that technical errors do not compound into fulfilment delays or customer service issues.

Operational handover and reconciliation workflows

Handover ensures your finance, operations, and ecommerce teams can manage the integration day to day. We provide operational documentation that defines where data lives, how to monitor order flows, and how to handle sync exceptions between Fulfil and Marketplacer. Your team will learn to perform daily checks on order imports and monthly inventory reconciliations. We ensure the CX and warehouse teams understand how to interpret alerts from the integration layer to resolve issues like stock discrepancies quickly. This documentation is designed as a practical reference for business users rather than a technical manual, ensuring that as marketplace sales scale, the team retains full control over the operational workflow.

Post-launch governance and data integrity maintenance

Support focuses on preventing small data discrepancies between Fulfil and Marketplacer from becoming major operational issues. We monitor the integration to ensure that stock updates and order flows stay accurate, identifying root causes when tracking details or inventory levels fail to sync. If an order fails to post or stock levels drift, we provide the technical oversight needed to resolve the issue quickly. This ensures your marketplace operations remain stable during high-volume periods, protecting your seller ratings and reducing the need for manual data reconciliation.

Integration operating model

The operating model treats Fulfil as the central system of record for the business. When an order is placed in Marketplacer, it is sent to Fulfil, which then updates stock levels across every sales channel you operate. This ensures that the inventory numbers seen by customers are always based on actual warehouse stock. Your operations team handles all fulfilment tasks within Fulfil, and once a package is sent, the integration updates the order status in Marketplacer automatically. This setup allows finance teams to rely on Fulfil for accurate sales and tax reporting, while ecommerce teams can focus on marketplace growth rather than manual data entry.

Common failures

Inventory latency and overselling

Operational impact: When inventory updates from Fulfil are delayed, Marketplacer can sell stock that is no longer available. This results in cancelled Sales Orders and forces the customer service team to manage refunds and customer complaints. At scale, frequent overselling erodes buyer trust and can negatively impact seller performance metrics on the marketplace.

Prevention / Action: The integration must treat Fulfil as the single source of truth for stock levels. Design the synchronisation logic to use frequent, delta-only updates to minimise latency, rather than relying on slow, full-catalogue syncs. Implement robust queuing with automated retry logic to handle transient API errors from either system, and monitor queue depth as a lead indicator of systemic performance issues.

Delayed or failed dispatch notifications

Operational impact: Fulfil generates the Item Fulfilment record with carrier and tracking details, but a failure to pass this back to Marketplacer leaves the customer without a shipping notification. This directly increases 'Where Is My Order?' (WISMO) queries for the customer service team. It can also breach marketplace SLAs for dispatch confirmation, risking penalties and damaging the seller's account health.

Prevention / Action: Structure the integration to monitor for the creation of Item Fulfillments in Fulfil. Ensure the process logic waits for the tracking number and carrier fields to be populated before attempting to send the update. The carrier names used in Fulfil must be mapped to the exact values required by Marketplacer's API to prevent data rejection. All failed dispatch updates must be logged in an exception queue for the operations team to review and resubmit.

Order value and payout reconciliation errors

Operational impact: Discrepancies between the order total calculated by Marketplacer (including fees and commissions) and the Sales Order value recorded in Fulfil create significant overhead for the finance team. They are forced to perform manual, line-by-line reconciliations between Marketplacer payout reports and Fulfil's financial journals. This process delays the month-end close and obscures true profitability per order.

Prevention / Action: Define the source of truth for order financials at the start of the project, which is typically Marketplacer. The integration must create Sales Orders in Fulfil with values that precisely mirror the source order, storing marketplace-specific charges in dedicated fields if necessary. Automating the posting of marketplace fees into a separate journal entry in Fulfil can greatly simplify the bank reconciliation process against payouts.

Product catalogue and pricing misalignment

Operational impact: If new SKUs created in Fulfil are not correctly published to Marketplacer, the inventory becomes invisible and unsellable. More subtly, if pricing, description, or attribute updates in Fulfil are not synchronised, listings become inaccurate, which confuses buyers and can lead to pricing disputes. This forces merchandising teams into manual auditing and correction of product data across both platforms.

Prevention / Action: Establish Fulfil as the definitive master for core product information like SKUs, descriptions, and pricing. The integration should be designed to manage the full lifecycle of a product, from creation and updates to eventual delisting. Define a clear mapping for all critical attributes, including handling of product variants, to ensure data is never dropped or misinterpreted. Schedule periodic data audits to catch and correct any drift between the two systems.

Disconnected returns and refund processing

Operational impact: A customer return initiated on Marketplacer does not automatically create a Return Merchandise Authorisation (RMA) in Fulfil. This means the warehouse team is unaware an item is being returned, and the finance team has no trigger to process a credit note or refund upon receipt. This disconnected process creates delays for the customer and requires manual coordination from the CX team to connect Marketplacer's request to Fulfil's inventory and finance workflows.

Prevention / Action: The returns process requires bi-directional synchronisation. A return request from Marketplacer must trigger the creation of an RMA record in Fulfil to alert the warehouse. Once the warehouse receives and approves the return in Fulfil, the integration must send a corresponding status update to Marketplacer to trigger the refund workflow. Define ownership for each step of the process to ensure statuses (e.g., 'Return Requested', 'Received', 'Refunded') remain aligned.

Frequently asked questions

We manage marketplace stock levels manually. When does this become a problem?

Manual processes create operational lag that becomes critical when marketplace sales volume reaches a point where inventory sync cannot keep pace with orders. This usually leads to overselling and stockouts, which damage your seller reputation and lead to marketplace penalties. Automation ensures that Fulfil pushes available-to-sell stock to Marketplacer to reflect current availability across all merchant storefronts.

Can we cancel or change orders directly in the ERP?

Marketplacer is typically the source of truth for the initial order creation. While you process the workflow in Fulfil, cancellations or changes are often initiated in the marketplace first to ensure the customer record and status update correctly. Changing only the ERP record can create sync illusion, where the marketplace still considers the original order active and expects fulfilment.

Why do tracking numbers sometimes fail to sync from Fulfil?

Marketplacer often requires tracking numbers to be associated with specific carrier codes or identifiers. If the fulfilment record in Fulfil uses a carrier name that the marketplace does not recognise, the update can fail. This leaves the order marked as 'Pending' in Marketplacer despite being shipped in the ERP, which can delay the settlement of funds.

How should we handle marketplace refunds and financial reconciliation?

Refunds initiated in Marketplacer do not always automatically trigger the corresponding accounting entries in Fulfil. A common failure occurs during partial refunds; if these are not mapped correctly to specific invoice lines, the entire order can be incorrectly flagged as fully refunded in the marketplace. Establishing a clear process for how returns in Marketplacer trigger sales returns in Fulfil is essential to avoid reconciliation debt at month-end.
