Purchase Order Parser Setup Guide

Automate purchase order processing with a custom PO Parser. Extract PO numbers, line items, and vendor details from purchase orders.

Before You Start

Before setting up your parser, ensure you have:

A PerfectParser account (sign up at perfectparser.com).
A healthy credit balance (each PO page processed consumes 1 credit).
A sample purchase order (PDF, PNG, or JPEG) to use during the parser setup.

Recommended Fields

We suggest configuring the following schema fields for your Purchase Order Parser to capture all essential order data.

Field Name	Type	Description
`po_number`	Text	The unique purchase order reference number.
`po_date`	Text	The date the order was created.
`vendor_name`	Text	The company or supplier receiving the order.
`customer_name`	Text	The customer company placing the order.
`billing_address`	Text	The billing address for the invoice.
`shipping_address`	Text	The physical destination address for the delivery.
`payment_terms`	Text	The payment terms agreed (e.g., Net 30, COD).
`total_amount`	Number	The overall total value of the order.
`line_items`	Table	Table containing `sku`, `description`, `quantity`, `unit_price`, and `total` for each row.

AI Prompt (Optional)

To help the AI parser extract field values with maximum accuracy, copy and paste the following prompt instructions into the AI Prompt (Optional) field during setup:

Extract the purchase order number, PO date, vendor name, customer company name, billing address, shipping address, payment terms, and total order value. Also extract the line items table containing the SKU/part number, description, quantity, unit price, and total line amount.
