Amazon Finance

Summarize connected Amazon finance and settlement data from Claude with Launch Fast MCP.

Amazon Finance lets Claude review settlements, fees, ledger lines, and order financial details. It uses Seller Central/SP-API data in Launch Fast. Use it to find costs, important fee groups, and financial effects on product performance.

Requires Seller Central/SP-API finance data.

In Launch Fast, go to Settings -> Authentication. Connect Amazon Seller Central/SP-API. Wait for finance and settlement reports to sync. Then use this tool.

How To Read The Results

Finance data is most useful when you connect it to sales and product economics.

Signal type	Look for
Positive signals	Look for stable fees in relation to sales. Confirm that settlements agree with sales periods. Confirm that reimbursements and credits are clear. Check that fees do not overwhelm top-selling SKUs.
Risk signals	Look for fees that grow faster than sales. Find high FBA, storage, refund, adjustment, or service fees. Find large charges with no explanation. Compare revenue with net proceeds.

Common Analysis Patterns

Use Claude to translate finance records into business questions.

Pattern	Ask Claude to identify
Fee pressure	Which fee categories hurt margin most.
Settlement explanation	Why a settlement was lower than expected.
SKU review	Which SKUs have the largest finance charges.
Order audit	What fees were applied to one order.
Marketplace comparison	Which marketplace has the highest fee pressure.
Sales follow-up	If strong sales were reduced by fees.
Inventory follow-up	If storage or inventory-related fees become a problem.

Suggested Workflow

Start With Summary

Run summary for the last 30 days.

Identify Fee Categories

Use fee_breakdown to identify the largest charge categories.

Inspect Ledger Lines

Use ledger_search to inspect specific SKUs, transaction types, or amount types.

Review Unusual Settlements

Use settlement_detail when a settlement looks unusual.

Investigate Orders

Use order_financials when one order needs investigation.

Compare Against Sales

Compare Finance with Sales to understand if revenue translates into proceeds.

Check Inventory Costs

Compare Finance with Inventory if storage, low sell-through, or stock issues can affect costs.

Common Empty Result Causes

Empty or thin finance results can mean no matching synced rows were found.

Cause	Recovery
Seller Central/SP-API is not connected.	Connect Seller Central/SP-API in Settings -> Authentication.
Finance reports have not synced yet.	Wait for finance sync to finish.
Date range is outside available settlement or ledger data.	Try a broader or more recent date range.
`settlement_id` or `order_id` does not exist in synced records.	Search recent ledger lines first, then use an ID from the results.
SKU spelling differs in Amazon.	Check the accurate seller SKU and retry.
Filters are too narrow.	Remove marketplace, amount type, transaction type, currency, seller, and connection filters.
Amazon has not made the finance report available yet.	Wait and retry later.

Try this recovery prompt:

Try the finance summary again for the last 90 days and remove seller, connection, SKU, marketplace, amount type, transaction type, and currency filters.

For a settlement or order:

Search recent ledger lines first, then use the settlement_id or order_id from the results for a detail lookup.

Safety Notes

Amazon Finance is read-only.

It can inspect	It does not change
Synced settlement activity, fees, ledger lines, order financials, marketplace, currency, transaction type, and amount type data.	Money movement, refunds, reimbursements, settlements, bank or payout settings, Seller Central, orders, listings, prices, inventory, or ads.

Claude can summarize finance data and suggest what to investigate. All financial and account actions must be taken manually outside this MCP tool.

Limits And Notes

Area	Note
Connection	Requires a connected Amazon Seller Central/SP-API account.
Rate limit	Amazon SP-API reporting tools allow 120 reads/min for each user.
Data availability	Results depend on finance and settlement data synced into Launch Fast.
Reporting lag	Finance data can lag behind sales data because Amazon settlement and ledger reporting can arrive later.
Date format	Dates must use `YYYY-MM-DD`.
Result size	Use `limit` to control how many ledger rows appear in detailed responses.
