## FAQ

### What does the stock example calculate?

ISLEM uses supplied stock, sales, lead times and whole-pack sizes. The synthetic EUR 150 budget funds 24 units for EUR 120, leaving EUR 30. Unfunded replenishment stays visible. This is rule-based planning, not a learned demand forecast.

### What does one completed report cost?

ISLEM charges $0.05 per completed report plus $0.00005 start; platform usage is included. Completed reports with review flags are billable. This starter has a $0.05005 run cap and starts no schedule or automatic purchase.

### How do I prepare my own input?

Replace the synthetic items and budget with your structured records. The main ISLEM page links to a free browser input builder and JSON templates. Use one currency for every cost; no ERP synchronization or automatic order is performed.

## 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/ryanbot_research/islem-b2b-automation.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`).
