# Compare supplier prices and flag SKU cost changes

**Use case:** 

Compare two small fictional CSV price lists. See matched SKUs, proposed cost updates and exceptions in downloadable review reports, with an aggregate summary table. Replace the sample files with your own catalog and supplier list. Detailed reports and run outputs remain private.

## About this Actor

This example demonstrates how to use [Supplier Price List Comparison — Excel & CSV SKU Reconciler](https://apify.com/exceptional_nugget/supplier-price-list-reconciler.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/exceptional_nugget/supplier-price-list-reconciler.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
