Inventory Change Audit Report: every change to a SKU quantity, with its cause

An inventory change audit report lists every change to a SKU quantity in order: when it happened, how much it moved, the resulting total, and what caused it. InfiPlex writes that history for each SKU, covering orders, uploads, manual edits, and API changes, so an AI agent connected to the MCP server can answer the question every inventory manager asks: why does this SKU show the number it shows?

  • Every changeOrders, uploads, edits, and API sets
  • Running totalThe quantity after each change
  • Cause attachedAn order number or the action taken

The prompt

Why does this SKU show the inventory quantity it shows?

Name the SKU. The agent reads the change history and walks the quantity back step by step.

Why is RS-310 at 12 units? Show every inventory change this week with the cause.

Used InfiPlex OMS integration

RS-310 is at 12. Changes this week, newest first:

When Change Resulting total Cause
Wednesday 9:14 AM -2 12 Order 418951
Wednesday 7:02 AM -1 14 Order 418933
Tuesday 4:40 PM Set to 15 15 Inventory upload
Tuesday 11:26 AM -3 9 Order 418790
Monday 2:15 PM +10 12 Manual inventory add
Monday 8:03 AM -1 2 Order 418622

The upload on Tuesday set the quantity to 15 when the running total was 9, an increase of 6. Everything since is order deductions.

Six rows explain the number. A change with an order number is a sale; a set is someone or something replacing the quantity. For quantities crossing to and from channels and partners, see the inventory sent to marketplace report.

What is in the report

What the InfiPlex inventory change audit report shows

Deltas and absolute sets are shown differently, because they answer different questions.

Column What it tells you
When Time of the change in your account time zone
Change Units added or removed, or the value the quantity was set to
Resulting total Total inventory for the SKU after the change, across warehouses
Cause What made the change: an order number, an upload, a manual edit, or product creation

Follow-up prompts that reshape the inventory change audit report

The first answer is a starting point. Each follow-up below is one more sentence in the same conversation, and the AI agent rebuilds the report from InfiPlex data each time.

  • “Show only the changes that were not orders.”Isolates uploads, edits, and sets.
  • “Which orders took the most units of RS-310 this month?”Follows the order numbers in the history back to the orders.
  • “Do the same for these five SKUs and summarize what looks unusual.”Runs the history per SKU and flags large sets or reversals.
  • “What does our 3PL report for RS-310 right now?”Checks the partner side for the same item.

Where the numbers come from

The InfiPlex data behind the inventory change audit report

One read per SKU, with orders and partner data a follow-up away.

  • inventory_change_history_getThe change history for a SKU: time, delta or set, resulting total, and note
  • inventory_getCurrent quantity, in total or per warehouse
  • order_getThe order behind any order number in the history
  • fulfillment_connection_productsWhat a 3PL or supplier last reported for the item

Every tool and its inputs are listed in the MCP tools reference. The same data is available as JSON through the InfiPlex REST API for teams that prefer a script.

Run it on a schedule

Schedule the inventory change audit report daily or weekly

Run it on demand, or daily for a short list of SKUs you are watching. A scheduled AI agent or a short script runs the same prompt from cron and delivers the result by email, Slack, or shared folder. The scheduled custom reports guide covers both routes, and the daily inventory by warehouse report agent is a worked example to copy.
