Invoice Matching & Supplier Quote Comparison | ISLEM

Check invoices against orders and deliveries, compare supplier quotes and plan stock reorders — in seconds, with every exception flagged.

Upload the CSV, Excel or PDF exports you already have — no JSON needed. Column names are recognised in English, German and Turkish. ISLEM returns a clear report as Excel, HTML, CSV and JSON: what matches, what does not, and what a person should check before paying or ordering. No AI key, no setup.

$0.02 per completed report, Apify platform usage included. Failed operations are not charged as reports.

▶ Try it in your browser first: the free input builder prepares a request without running anything.

Open the free input builder to prepare a small invoice, stock or supplier request in your browser. No key, upload or engine run is needed to prepare the JSON.

Start with your task	What to send	Preview and prepare
Check an invoice	Invoice, order and delivery lines with matching SKUs	10 invoiced / 8 delivered
Plan stock within a budget	Stock, sales, lead time, pack size and unit cost	EUR 150 budget example
Compare suppliers	Required items, offers, shipping and delivery limits	EUR 115 vs EUR 130 example

These are synthetic demonstration records processed by ISLEM, not customer data or a market accuracy benchmark.

Upload your files

Pick the operation, then drop your files into the matching fields:

Operation	Upload	Columns ISLEM looks for
Invoice matching	Invoice + purchase order (+ delivery note)	SKU / Artikelnummer / Ürün kodu, Quantity / Menge / Adet, Unit price / Einzelpreis / Birim fiyat
Supplier comparison	Items you need + one file with all supplier quotes	Supplier / Lieferant / Tedarikçi, SKU, Unit price; optional Shipping and Lead time
Stock planning	Stock and sales list	SKU, Stock / Bestand / Stok, Sold / Verkauft / Satış; optional Pack size, Unit cost, Lead time

Numbers like 12,50, 1.234,56 and 1,234.56 are read correctly; a truly ambiguous value such as 1.500 stops the run and asks you to choose the number format, so nothing is guessed. Total rows are skipped and repeated SKUs at the same price are added up. Every finding names the file and row it came from.

Try it with sample files: invoice (German), order (English), delivery note (Turkish) · needed items, supplier quotes · stock list. You can also paste these links straight into the file fields. The invoice sample finds a short delivery on A1 and €1.50 over-billing on B2.

The three jobs most teams start with

You send	You get back
🧾 Invoice + purchase order (+ delivery note)	Quantity and price differences per line, what is safe to pay, what to query with the supplier
📦 Supplier quotes for the same items	Total landed cost incl. shipping, missing items, the cheapest offer that meets your budget and delivery date
📊 Stock, sales and lead times	Reorder quantities in whole packs, days of cover, and a purchase draft that fits your cash budget

Who uses it

• Accounts payable & bookkeepers — catch over-billing and short deliveries before paying.
• Purchasing teams — compare quotes on true total cost, not just unit price.
• Shops, wholesalers and warehouses — know what to reorder this week and what it costs.
• Automation builders (n8n, Make, Zapier, custom scripts) — one API call per check, structured JSON back.

How to run it

1. Pick an operation (for example reconciliation, procurement or inventory) and paste its payload. The input form is prefilled with a working example.
2. Run. Most reports finish in under 10 seconds.
3. Open the run's Storage: report-0.html (readable report), report-0.xlsx (Excel) and result-0.json. Each report also appears in the Dataset.

Batch several checks with {"jobs": [{"operation": "inventory", "payload": {...}}, ...]} (up to 100 jobs). Use operation: "workflow" to chain steps.

{
  "operation": "reconciliation",
  "payload": {
    "invoice_id": "INV-001",
    "invoice":  [{"sku": "A1", "name": "Cable 1 metre", "quantity": "10", "unit_price": "12.50", "currency": "EUR"}],
    "order":    [{"sku": "A1", "name": "Cable 1 metre", "quantity": "10", "unit_price": "12.50", "currency": "EUR"}],
    "delivery": [{"sku": "A1", "name": "Cable 1 metre", "quantity": "8",  "unit_price": "12.50", "currency": "EUR"}]
  }
}

Pricing

$0.02 per completed report (a single operation or a whole connected workflow) plus a $0.00005 start fee. Apify platform usage is included — there is nothing else to pay. Operations that fail or workflows stopped before completion are not charged. A batch run can produce several reports. The run stops scheduling new jobs when your spending limit is reached.

Good to know

• Inputs: uploaded CSV, Excel (.xlsx) or text PDFs with a table, or structured JSON. UBL XML invoices are supported. Scanned-PDF and photo OCR are not included. Limits: 2 MiB input, 1,000 rows per list, 100 jobs per batch, 20 workflow steps.
• Read-only: ISLEM never pays, emails, orders, refunds or edits your systems. It flags; a person decides.
• Method: explicit rules and exact decimal maths, not guesswork. Stock plans use average historical demand. Reference data (FX, holidays, LEI) is dated and sourced.
• Troubleshooting: 422 = invalid input (check the error field and the example); review_required = open the report; no delivery note? set check_delivery=false.

Process only records you are authorized to use. Reports are operational aids, not legal, tax, credit or sanctions decisions.

Need public company research as well?

RyanBot on Apify discovers companies by city and sector or researches supplied websites. RyanBot on RapidAPI starts from your website list. Reports can include public contacts, hiring, technology, SEO and ten buyer perspectives with sources.

ISLEM processes the operational records you supply. These are separate products and subscriptions; there is no automatic transfer or shared quota. Public company research does not reveal private invoices, stock or purchasing intent.
