Marketplace monitoring that shows where your products go missing online.

Marketplace monitoring is the regular checking of online marketplaces and retailer sites for three things: whether each product is listed, whether it is in stock and whether shoppers can buy it. Most marketplace monitoring is sold as software that leaves the checking and follow-up to the brand's own team. Nextyn runs marketplace monitoring as a managed service, delivering finished findings by SKU and platform with a ranked action list.

A Nextyn marketplace monitoring service delivers three outputs: a platform-by-platform availability report, a range gap list by SKU, and a prioritized action list for each platform. Each output is finished work, checked by Nextyn researchers rather than left in a dashboard:

• Availability report: listed, missing and out-of-stock status for every SKU in scope
• Range gap list: products shoppers cannot find on a platform where they should be sold
• Action list: the gaps that hit the most important products and platforms, first

Nextyn checks four things on every platform in scope: listing status, stock status, range coverage and the seller behind each listing. Nextyn researchers check each platform directly, and interviews with marketplace category managers and sellers explain why each gap opened:

• Listing checks, recording whether each SKU appears and can be found by search
• Stock checks, recording out-of-stock status across the period in scope
• Range coverage, comparing what is listed with the range the brand planned
• Interviews with marketplace category managers and third-party sellers, on why listings drop

Nextyn monitors the marketplaces, retailer sites and delivery apps that sell a client's category in the United States, the United Kingdom and Europe, among other markets. Platforms and markets are agreed at scoping, so a two-platform US check and a multi-country European program each get their own SKU and platform list. Nextyn's retail research spans more than 85 countries and over 50 languages, and recent work includes physical and e-commerce audits for a premium air-purifier market entry.

Nextyn recommends marketplace monitoring at three points: when online sales fall without a clear cause, after a range or listing change on a major platform, and before a joint business plan with an online retailer. At each point, SKU-level availability shows which gaps are costing sales and which to fix first. Ongoing monitoring then catches new gaps before they show up in the monthly sales report.

A Nextyn marketplace monitoring project runs in four steps, from brief to read-out, and nothing is commissioned until the client approves the plan. The client sees the platform list, check frequency and price before any work starts, and reviews every finding with the Nextyn team.

1. Submit the brief: the SKU list, the platforms each product should be sold on and which products matter most.
2. Receive a plan within 48 hours: which platforms will be checked, how frequently, who will be interviewed and what the work costs.
3. Approve the plan: checks start only after sign-off.
4. Review the read-out: platform checks and interviews read together, showing where sources agree, where they conflict and what is still open.

Nextyn sends a research plan within 48 hours of receiving the brief, stating which platforms will be checked, how frequently, and what the work costs. The plan sets the length of the first read and the rhythm of later checks, matched to the number of SKUs and platforms in scope and how fast availability moves. Nothing is commissioned until the plan is approved.

Nextyn marketplace monitoring is a managed service that delivers finished findings and a ranked action list, while monitoring software delivers a dashboard for the brand's own team to check and interpret. The two suit different teams: software suits a brand with analysts to run it, and the service suits a team that needs answers without another tool.
