# Step 4: Create a Forecast

A forecast tells Moselle what demand to plan for. You'll create an empty forecast on the Forecast page, then use Mo to populate it from your existing projections or sales data.

**Time required:** 20–30 minutes

{% hint style="info" %}
**No historical data in Moselle yet?** You can still build a forecast. Upload your existing sales spreadsheet or revenue targets to Mo and let Mo write the values directly into your forecast.
{% endhint %}

***

## Step 1: Create an Empty Forecast

1. Select **Forecast** from the left nav
2. Click **+ Create Plan**
3. Enter:
   * **Forecast name** (e.g., "2025 Plan")
   * **Start date**
   * **Number of months** to plan ahead
   * Optionally check **Master Plan** to set this as your primary forecast
4. Click **Next**, then **Save**

You now have an empty forecast. Mo will fill in the values.

## Step 2: Use Mo to Build Your Projections

Open a **Mo chat session** and upload your existing data — a sales spreadsheet, revenue targets, or any projection document you already have.

**Example prompts to get started:**

* *"Here's our sales data from last year. Can you write a 12-month forecast into our 2025 Plan?"*
* *"We're targeting $2M in revenue next quarter. Distribute this across our SKUs based on our sales mix."*
* *"Use this spreadsheet to build a forecast for Q2 and Q3."*

Mo will review your data, propose forecast values, and show a preview table before writing anything.

{% hint style="info" %}
**Review before committing.** Mo shows every proposed change in a preview table. You can edit individual values inline before confirming.
{% endhint %}

For a deeper guide on working with Mo for forecasting, see [Build Your Forecast with Mo](/planning-and-execution/forecasting/build-your-forecast-with-mo.md).

## Alternatively: Use AI Models *(if your sync has completed)*

If your Shopify or Amazon integration has finished syncing historical sales data, you can generate forecasts directly from that data instead.

**Bottom-Up (AI model):**

1. Open your forecast → click **Gear Icon** → **Modify Forecast**
2. Select **Change Forecast Method** → choose an AI model
3. Click through the steps and click **Generate Forecast**

**Top-Down (Revenue targets):**

1. Open your forecast → click **Gear Icon** → **Modify Forecast**
2. Select **Adjust Revenue Targets**
3. Enter your sales goals by channel and month
4. Click **Generate Forecast**
