# Ingredient Change History — Pricing & Inventory Audit Trail

> Track every change to ingredient pricing and inventory with a field-level audit trail.

## Overview

Knead keeps a detailed history of changes to your ingredients. Every time you update an ingredient's cost, quantity on hand, supplier, or other fields, the change is recorded with a timestamp. This gives you a complete audit trail so you can see when prices changed, who updated stock levels, and how your costs have shifted over time.

## What Gets Tracked

Change history is recorded at the field level. This means Knead does not just log that an ingredient was edited — it records exactly which field changed, what the old value was, and what the new value is.

Tracked fields include:

* **Cost per unit** — See how your ingredient costs have changed over time.
* **Quantity on hand** — Track stock adjustments and inventory corrections.
* **Supplier** — Know when you switched suppliers.
* **Unit of measurement** — See if the unit was changed.

## Viewing Change History

1. Open **The Pantry** from the sidebar.
2. Tap on any ingredient to open its detail page.
3. Scroll to the change history section.

Each entry in the history shows:

* **Date and time** of the change.
* **Field** that was modified.
* **Previous value** and **new value**.

## Why Change History Matters

### Track Cost Trends

Ingredient prices fluctuate. Change history lets you see exactly when butter went from \$4.50/lb to \$5.25/lb, so you can trace how your recipe costs changed over time and decide if you need to adjust product pricing.

### Audit Stock Adjustments

If your quantity on hand seems off, check the change history to see every adjustment. This helps you identify whether stock was manually corrected, depleted by orders, or updated during a purchase recording.

### Informed Purchasing Decisions

Seeing a pattern of price increases from a supplier? The history makes it visible so you can shop around or buy in bulk before the next price hike.

<Tip>Pro tip: Check ingredient change history before updating your product prices. It shows you exactly how much your costs have shifted and helps you decide how much to adjust.</Tip>
