# Compare supplier prices before a catalog CSV update

**Use case:** 

Compare supplier and catalog CSVs by SKU before preparing a bulk price update. This synthetic example returns one proposed change and five exceptions for conflicting prices, an unknown SKU, a negative price and a missing SKU. Leading-zero SKUs and Hebrew titles are preserved. Review the output before importing; this task does not update Shopify or create a finished Matrixify file.

## Input

```json
{
  "currentCatalogCsv": "sku,title,price_ils\n001,כוס כחולה,89.00\n002,כוס אדומה,99.00\n003,מגבת פשתן,129.00",
  "supplierUpdateCsv": "sku,price_ils\n001,₪99.00\n002,99.00\n003,119.00\n003,125.00\n004,79.00\n005,-5.00\n,49.00",
  "currencyNote": "ILS (period decimals; currency symbols stripped from supplier prices)",
  "skuColumn": "sku",
  "titleColumn": "title",
  "priceColumn": "price_ils"
}
```

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
