Overview

Service overview

This is a managed service in which we operate Amazon advertising and optimize listings on behalf of our clients on an ongoing basis.

With the client's authorization, we access their Seller Central and Amazon Advertising accounts and manage operations for them. Access is limited to what the engagement requires, and the client can revoke it at any time.

Using our in-house monitoring platform, we automatically collect campaign-level advertising spend, sales, fees, inventory, and reviews every day, and report anomalies as soon as they are detected. Operational decisions are based on daily actual data rather than individual judgment.

Services

Core offerings

  1. 01

    Daily advertising spend monitoring and anomaly detection

    We collect campaign-level advertising spend daily across multiple advertising accounts. We automatically detect missing days, spend carried over from the previous day, and campaigns from other accounts being mixed in, so that the daily dataset stays complete. Products with advertising spend but no sales, and products whose advertising cost ratio exceeds a threshold, are reported as soon as they are detected.

  2. 02

    Advertising campaign optimization

    Based on search term reports, we add negative keywords, adjust bids, and decide when to pause delivery. We track per-product advertising cost ratio and projected month-end figures daily, and reallocate budget accordingly.

  3. 03

    Deal enrollment and automation

    We periodically check availability of Best Deal and Lightning Deal slots, evaluate the maximum price Amazon will accept, and submit enrollments. Clients can set a maximum discount rate; if a deeper discount would be required, we do not enroll. We secure the next slot before the current one ends so that promotional periods do not lapse.

  4. 04

    Coupon creation and scheduled renewal

    We create coupons with the specified products, discount rate, and period, and automatically create the next period before expiry, managing coupon codes to avoid collisions.

  5. 05

    Automated review requests

    We send review requests for delivered orders using Amazon’s official "Request a Review" feature via the SP-API Solicitations API. The message is Amazon’s standard text; we do not use custom wording. We send at most one request per order, only within the eligible window, and maintain a ledger to prevent duplicate sends.

  6. 06

    Listing creation and maintenance

    We create new listings, consolidate variations such as flavor and size, upload product images, and build A+ content. We maintain attributes such as category, brand, and package dimensions in line with Amazon's catalog requirements.

  7. 07

    Daily reporting on sales, fees, and inventory

    We aggregate units sold, sales, Amazon fees, promotional discounts, and FBA inventory daily, and provide them to clients together with month-end projections.

Benefits

Benefits

Wasted advertising spend surfaces the next day

Clients do not have to wait for a monthly report to see spend that is not producing sales. Because missing or mismatched data is detected automatically, the figures behind each decision stay reliable.

No missed deal slots

Deal slots fill on a first-come basis, and only one enrollment per product can be active at a time. Automated checking and enrollment means opportunities are not lost to oversight.

No missed review opportunities

Review requests can only be sent roughly 5 to 30 days after delivery. Because we process orders closest to their deadline first, eligible orders are not left unsent.

No need to build listing work in-house

New listings, images, A+ content, and catalog attributes are an area where Amazon's requirements change often, making in-house work costly to learn. We handle it.

Expertise

Expertise

We currently operate 14 Amazon seller accounts and monitor 11 advertising accounts daily. Our primary categories are food and beverage.

Our platform is developed in-house. It integrates with Amazon Advertising reports and the Selling Partner API (SP-API) to collect advertising spend, orders, inventory, fees, and reviews automatically every day. Built-in self-checks detect missing or anomalous data, so the figures underlying our reports are verified mechanically.

For SP-API, with our clients' authorization, we have implemented and operate integrations using the Orders, Inventory, Catalog, Pricing, Listings, Solicitations, Reports, Finances, and FBA Inbound roles.

Testimonials

What our clients say

The product we sell is a premium-priced dressing. Because the unit price is high, how we spend on advertising changes our margin significantly, so controlling advertising has always been our single biggest issue. Previously we could only look back on it once a month, and by the time we realised money had been wasted it was often too late. Since we started, we know the next day where the waste is, and the speed at which we can act has clearly changed.
ROPES Inc.Representative Director 大内 康勢
With Amazon deal slots, overlooking a single condition or the timing of an application means losing the opportunity entirely. Overseeing both sales and our retail store, detailed checks inevitably got put off. Now that the deal slots are managed for us, we no longer miss them, and our sales no longer come in waves.
Kyushu Hachinoko Honpo Inc.Senior Managing Director, Sales and Retail 平本 光志
Until now, what to do with customers after they had bought from us once was left untouched. By using the review request feature, we can now reach a large number of past customers at once, and the part of the business we had never been able to act on has finally started moving.
