Amazon Selling Partner API integration

Every Amazon account we manage, reviewed on the same numbers.

WISER CO., LTD. provides Amazon account management, advertising and operational consulting to independent seller clients in Taiwan. WISER Amazon Operations Platform is the read-only application our account managers and our seller clients use to review how each account is performing.

Each seller authorizes access to their own Amazon account explicitly, through Amazon’s Login with Amazon consent flow. Authorization can be withdrawn at any time.

What it does

Built around the weekly account review

Each function below is listed with the Amazon data it relies on, so the purpose of every role we request is explicit.

Sales and traffic dashboard

Ordered product sales, units, sessions, page views, unit session percentage and Buy Box percentage are consolidated into a single view per marketplace, so a seller does not have to download and reconcile separate Seller Central reports each week.

Sales and Traffic Business Report — Brand Analytics role.

Recurring performance reports

Weekly and monthly reviews are generated per account, comparing each period against the one before it so that changes in sales, conversion and traffic are visible early rather than at the end of a quarter.

Sales and Traffic Business Report — Brand Analytics role.

Inventory monitoring and stock-out alerts

Fulfilment inventory levels are tracked against recent sales velocity, and account managers are alerted before a fast-moving listing runs out of stock.

FBA Inventory — Amazon Fulfillment role.

Marketplace coverage

Which Amazon marketplaces a seller is active in, and their participation status in each, is read directly from Amazon so that reporting always covers every storefront in scope and none is quietly missed.

Marketplace participation — Selling Partner Insights role.

Account health monitoring

Each managed account carries a four-level health signal combining reporting cadence, contract status, inventory position and open follow-up items, so the accounts needing attention this week are obvious at a glance.

Derived from the data above; no additional Amazon data.

Advertising performance review

Advertising spend, sales, ACOS and campaign-level breakdowns are consolidated per account and per marketplace, with week-over-week movement highlighted.

Amazon Advertising data (Amazon Ads API) — separate from SP-API.

Client service workflow

Meeting records, communication history, follow-up commitments and contract milestones are kept against each account so that nothing agreed with a seller is lost between team members.

No Amazon data — internal service records only.

Scope

What the application does not do

  • The application is read-only. It does not create, update or delete listings, prices, inventory records, orders, shipments or buyer communications.
  • It does not retrieve buyer names, addresses, telephone numbers, email addresses or any other restricted personally identifiable information.
  • Each selling partner’s data is logically segregated, and access is restricted according to the job responsibilities of the personnel assigned to that account.
Who it is for

Managed-service clients only

The application is used exclusively by selling partners who have engaged us for account management, together with the account managers assigned to them. It is not sold as a standalone product and is not available for self-service sign-up. Access is granted by our team when an engagement begins and removed when it ends.

Pricing

Transparent monthly fee plus commission

The application itself is provided at no additional charge to our managed-service clients. It is included as part of our Amazon account management service, and the fees below are the service fees for that engagement. All fees are quoted and billed in US dollars.

Standard

Single marketplace, established catalogue

USD 1,500 per month
Monthly service fee
+ 3% of monthly GMV
Commission on sales
  • Amazon storefront management
  • Access to the application for the seller’s own account
  • Weekly performance reporting
  • Advertising campaign management and optimisation
  • Inventory monitoring and stock-out alerts

Advanced

Multiple marketplaces, or a broader scope of work

USD 2,000 per month
Monthly service fee
+ 3% of monthly GMV
Commission on sales
  • Everything in Standard
  • Multi-marketplace coordination
  • Dedicated account manager
  • Monthly business review

Larger or more complex engagements — additional marketplaces, catalogue build-out, or project work — are quoted individually. Depending on scope, those quotations may be structured as a flat monthly fee, a project fee, or a fee based on a percentage of sales or advertising spend. A written quotation is always issued before an engagement begins.

Worked examples

A seller on the Standard plan with USD 40,000 in monthly GMV pays the USD 1,500 monthly service fee plus 3% commission on that GMV (USD 1,200) — USD 2,700 for the month. Use of the application is included at no additional charge.

A seller on the Advanced plan running three marketplaces with USD 100,000 in combined monthly GMV pays the USD 2,000 monthly service fee plus 3% commission on that GMV (USD 3,000) — USD 5,000 for the month, covering all marketplaces in scope.

  • Amazon advertising budget is paid directly to Amazon by the selling partner and is not included in the fees above.
  • Amazon referral fees, FBA fulfilment fees and other charges levied by Amazon are billed by Amazon to the selling partner and are not included.
  • Fees are exclusive of any taxes that may apply.
  • Additional services such as creative and listing design, influencer marketing, cross-border website development, and management of other marketplaces are available and are quoted separately on request.
Data handling

One seller’s data, used for that seller only

A selling partner’s data is used only to operate and report on that selling partner’s own account. It is never pooled across clients, never used to benchmark one seller against another, and never sold. Full details — including where data is stored, how long it is kept, and how to have it deleted — are in our Privacy Policy.
