# Check invoice quantities against orders and deliveries

**Use case:** 

Match supplied invoice, purchase-order and delivery lines. Flag price and quantity differences with traceable JSON, Excel and HTML reports. Start with a synthetic 10-invoiced / 8-delivered example, then replace it with your records.

## FAQ

### What does this example find?

The synthetic example compares 10 invoiced units with 8 delivered units. Replace its structured invoice, order and delivery lines with yours. Reports preserve exceptions and evidence; no payment is approved or executed.

### What does one completed report cost?

ISLEM charges $0.05 per completed report plus $0.00005 start; platform usage is included. A completed report with exceptions is billable. The saved run cap is $0.05005. Failed operations do not incur the completed-report event fee.

### Can I use scans or connect my accounting system automatically?

This task needs structured records. Arbitrary scanned-PDF OCR and automatic accounting updates are not included. ISLEM also offers stock, supplier, finance, CRM and service operations in the main Actor. Each task has its own input requirements.

## About this Actor

## 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`).
