# Where do I enter my lead times, safety stock and warehouse stock?

Checked against Nova's code on 2026-11-09

Open **Data Inputs › Supply chain**. Type your production lead time on your account's line of the top table, then your transit times and stock targets on each warehouse's line. Every product inherits them, and the Inventory page tells you what to order and by when.

## Who can edit it?

Admins and Workspace owners; a Workspace member sees it locked. It covers Seller Central accounts only, so a workspace that also holds Vendor Central sees it marked **3P**.

## What is on the page?

**Warehouse & 3PL setup**, per account and warehouse. Nova finds your warehouses in your shipments to Amazon.

| Column | What to type |
|---|---|
| **Target stock at Amazon** | Your safety stock at Amazon, in days of supply |
| **Target stock at warehouse / 3PL** | Days of supply you keep at your warehouse |
| **Transit to Amazon** | Days from your warehouse to sellable at Amazon |
| **Transit to warehouse** | Days from the factory to your warehouse |
| **Production lead time** | Days from your order to goods leaving the factory, per account |

**Product overrides**, per product and warehouse:

| Column | What to type |
|---|---|
| **At warehouse / 3PL** | Units held there: click **+ Count** |
| **On order** | Your open supplier orders. Click **+ Order** |
| **Units per case** | The order is rounded up to a multiple of it |
| The five numbers above | Only where this product differs |

A number in gold is Nova's default; in grey it comes from the warehouse or account line. Type yours to replace it. Defaults and the formula are in [Replenishment](/docs/inventory-and-catalogue/replenishment).

## How do I fill it fast?

**With your AI assistant.** Click **Copy the prompt** in the banner, then drop your 3PL count, supplier orders or lead times into Claude, ChatGPT or Gemini connected to Nova. It previews the changes and saves after you confirm. See [Connect Claude](/amazon-ai-agents/connect-claude).

**With a spreadsheet.** **Import / Export › Download the product table**, edit, then **Upload the product table**. Only the lines in your file change.

## What does the Inventory page show then?

| Chapter | Columns |
|---|---|
| **At your warehouse / 3PL** | **Warehouse**, **Units**, **On order**, **Running total**, **Days of supply** with your warehouse |
| **What to order** | **Lead time**, **Target stock**, **Units to order**, **Order by** (**Now**, or **Late N d** once passed) |

## Common mistakes

| You see | Why | Fix |
|---|---|---|
| Order dates look wrong | Lead times still on Nova's defaults (gold) | Set your production lead time first |
| Units to order too high | No count at your warehouse, so only Amazon stock and orders count | Click **Missing input** and add the counts |
| Units to order is blank | The product sold nothing in the last 30 days | Nothing to order yet |
| Stock counted twice | Your warehouse units are also your FBM listing | Keep **Include FBM** off on Inventory, or enter only the difference |
