# Product suppliers and cost tiers

Suppliers often charge less per unit when you buy more, and the same product can come from more than one supplier. If a product only has one flat cost, your quotes miss those savings or show the wrong profit. In OrderEazi, each product lists its suppliers, each with its own item code and cost tiers by quantity.

### Before you start

You'll need the **Edit Products** permission, in the **Products** permission group. Each supplier must already exist in [Suppliers](/central/order-management/suppliers.md).

### How to add a supplier to a product

1. Open the product with **Edit**.
2. Under **Suppliers**, select **Add Supplier**.
3. Choose the **Supplier** and enter the **Supplier Item Code** (the code your supplier uses for this product).
4. Add the **Recommended Retail Price** and **Direct Product Link** if you have them.
5. Tick **Preferred Supplier** if this is the supplier you normally buy from.
6. Select **Save**.

Only one supplier can be preferred. **Stock Level** and **Stock Last Updated On** fill in when the supplier sends stock through a supplier feed. **Lead Time (Days)** is worked out from your past goods received vouchers.

### How to set cost tiers

1. On the supplier's row, under **Unit Cost(s)**, select **Manage**.
2. Select **Add New Tier**.
3. Enter the **Quantity Tier** (the quantity the price starts at) and the **Cost Price**.
4. For a supplier in another currency, enter the **Exchange Rate**, or leave it empty to use the live rate.
5. Select **Save Changes**.

When a project line uses this supplier, OrderEazi takes the cost from the highest tier at or below the line's quantity.

**Example:** A supplier charges R120 a mug for 1 to 99, and R95 from 100. You add a tier at **Quantity Tier** 1 for R120, and one at 100 for R95. A project line for 250 mugs is costed at R95, and a line for 40 mugs at R120.

### How the supplier is chosen on a project

If your organisation uses default suppliers, a new project line uses the preferred supplier. Otherwise it uses the cheapest supplier for that quantity. Reps with the right permission can change the supplier on the line.

### Supplier feeds

Products from a supplier feed app are kept up to date by the feed. It updates the product's details and stock, but keeps a description you've changed and any notes or image you've added. If your organisation has turned on **Auto-remove stale feed suppliers**, a supplier is removed from a product when the feed hasn't sent that product for 48 hours.
