Purchase Order API

Purchase Order Data Extraction API

A purchase order (PO) is the official document a buyer issues to a seller, authorising a purchase and specifying the items, quantities, and agreed prices. In procurement and accounts payable workflows, POs arrive in countless layouts: some arrive as neatly formatted PDFs from procurement systems, others as scanned paper forms, email attachments, or even hand-written sheets. ByteIt's Purchase Order extraction engine reads any PO layout and returns structured data ready for your ERP, accounting, or procurement system.

Deliver clean, structured data directly into ERP systems, accounting tools, and procurement platforms

How it works

  1. Step 1

    Upload

    Send the document to the API as a file or a URL no special formatting required.

  2. Step 2

    The engine reads the document

    The engine analyzes the page layout and identifies the content that matters. The engine reads the entire purchase order layout, identifying and extracting both top-level metadata (PO number, dates, supplier and buyer information, shipping address, payment terms, currency, subtotal, tax, and total) and the table of line items (description, quantity, unit price) from any position on the page.

  3. Step 3

    Structured JSON is returned

    Every extracted element comes back as structured JSON, positioned and typed, ready to feed into downstream systems.

  4. Step 4

    Confidence-based review

    Each field carries a confidence score, so low-confidence results can be routed for human review instead of trusted blindly.

Use cases

Automated PO data entry into ERP and accounting systems

Your procurement team receives dozens of POs from different departments each day. ByteIt extracts the PO number, vendor details, line items, and totals, then sends the structured data into your ERP (Enterprise Planning) or accounting software via a workflow automation tool such as n8n, Zapier, or Make. Purchase orders are recorded, approved, and tracked without anyone typing a line.

Three-way matching for accounts payable

In a typical procure-to-pay cycle, the accounts payable team must match the purchase order against the corresponding goods receipt and invoice. ByteIt's PO extraction captures item-level data (quantities, prices, tax) so your AP automation system can perform three-way matching automatically, flagging discrepancies for review and accelerating payment approvals.

Inventory and supply chain planning

Procurement managers need visibility into incoming stock to plan inventory levels and avoid stock-outs. By extracting line-item quantities and delivery dates from purchase orders in real time, ByteIt feeds supply chain planning tools with accurate, up-to-the-minute data on what goods are on order and when they are due to arrive.

Spend analysis and procurement analytics

Finance teams can aggregate data from thousands of historical purchase orders to understand spending patterns by department, supplier, or product category. ByteIt converts paper and PDF POs into structured records that can be loaded into a data warehouse or analytics dashboard, enabling cost-saving decisions backed by complete data.

Cross-border PO processing in multiple currencies

International procurement involves POs in different currencies, tax regimes, and date formats. ByteIt extracts currency, VAT rates, and delivery terms regardless of the regional format, making it straightforward to standardise purchase order data from global suppliers into a single enterprise system.

Frequently asked questions

How does ByteIt handle purchase orders with different layouts from different suppliers?

ByteIt uses an AI model trained on a broad range of purchase order formats, not a fixed template. It reads the document's layout dynamically, so whether a PO comes from a global ERP system or a small supplier's handwritten form, the engine identifies and extracts the relevant fields without manual rules or template configuration.

Can it extract line items from complex PO tables?

Yes. The engine handles line-item tables with merged cells, multi-line descriptions, nested headers, and varying column orders. Each row's description, quantity, unit price, and line total are extracted and returned as a structured array, preserving the relationship between items.

What file formats are supported for purchase order extraction?

ByteIt accepts PDF (both digitally native and scanned), JPEG, PNG, and TIFF files. Multi-page documents are supported, and all pages are processed together to capture the complete PO data.

How is the API integrated into an existing procurement or accounting workflow?

The extraction engine is accessed via a standard REST API. You can send purchase orders to the endpoint and retrieve structured JSON results. The API can be wired into workflow automation tools such as n8n, Zapier, or Make to push extracted PO data directly into ERPs, accounting platforms, or databases.

What is the pricing model for PO extraction?

ByteIt offers a free tier for testing and evaluation, plus pay-as-you-go and subscription plans that scale with your document volume. Visit the pricing page for current rates, quotas, and enterprise options.

Does the engine handle POs in languages other than English?

Yes. The model supports multiple languages commonly found in US and European procurement documents, extracting field values regardless of the language used in the PO.

How accurate is the extraction for low-quality scans or photographs of purchase orders?

The engine is trained on real-world document variations including folded pages, uneven lighting, and moderate blur. While very poor-quality scans may reduce confidence on certain fields, the model generally produces reliable results across a wide range of input quality levels.
