What is an inventory inquiry document INVRPT?

The primary purpose of the inventory advice EDI document is for the supplier to provide the purchaser the amount of goods they have on hand and available, and on order for future possibly delivery dates. This allows better management of buying needs and is often used in a drop ship order management model to support ecommerce management.

There are two broad types of EDI documents, split between the EDIFACT and ANSI X12 standards. EDIFACT is the standard advocated by the UN, and is used in Australia, New Zealand, Europe, and parts of Asia, and uses a inventory inquiry/advice document called ‘INVRPT.’ The ANSI X12 standard is used in North America, and uses the 846 document.

The key data elements included in the inventory inquiry.

  • Identifying number
  • Inventory date
  • Product item identifiers/services such as UPC/EAN/GTIN needed with their respective quantities

Additional data that may also be included in the inventory inquiry are:

  • Out of stock items and restock dates
  • Discontinued products
  • Supplier warehouse locations with on hand and available amounts by item
  • Vendor number
  • Additional item identifiers such as buyer item number and vendor part number
  • Item description


There are benefits to both the purchaser and the supplier of implementing electronic trading of the inventory advice. Many of these are dependent on how automated and integrated the transaction is for both parties. Some of the benefits include:

  • Enables the supplier to advise when product is out of stock or no longer being made
  • Facilitates better management of ecommerce drop ship
  • Communicates to the purchaser when the item will be available again if out of stock
  • The purchaser is able to better plan warehouse and store ordering
  • Enables the purchaser (typically a retailer within our network) to manage publicly available data on their website, such as item out of stock, quantity available, or remove the item from the website
  • Supports the ability to order non-stock items/special orders
