# Amazon Seller Central integration for paid acquisition

Hendrik reads Amazon Seller Central orders, order items, financial events, inventory, and listings so you can put marketplace operations beside Amazon advertising.

## Questions Hendrik can help answer

- Are marketplace operations limiting an advertising choice?
- Did financial event timing change the commercial result?
- Which listing needs a stock or offer review?

## Illustrative example

### Explain a marketplace value gap

Same 30-day USD windows

*About this example: Synthetic data · illustrative analysis · Hendrik only acts with the permissions you give it.*

- Order value (Amazon Seller Central): US$140,000 → US$142,000
- Financial event amount (Amazon Seller Central): US$131,000 → US$119,000
- Attributed sales (Amazon Ads): US$62,000 → US$67,000

### What Hendrik checks

- **Separate date bases:** Check financial-event timing before interpreting the order gap.
- **Review refunds and fees:** Inspect the financial event types rather than treating them as net sales.
- **Avoid double counting:** Do not add Amazon Ads attributed sales to marketplace order value.

### What Hendrik sees

Order value was nearly flat while financial event amount fell and Amazon Ads attributed sales rose.

### What to do next

Review the financial-event composition before changing Amazon Ads budget.

**Limit:** The integrations report different measurement systems and are not reconciled here.

## What Amazon Seller Central contributes
