Add a Price or Price Levels to an Item

By Following these steps add prices to an item for NetSuite Point of Sale. You can have a single base price for all stores. Price levels let you sell an item for different prices, and can be used for stores that you internally assign to different marketing areas or regions. For international retailers, you can set prices in the different currencies that you use.

To add Prices to an Item:

1. Log in to NetSuite as an administrator.
2. Go to Lists > Accounting > Items.
3. Click Edit for the item to update.
4. Click the Sales / Pricing subtab.
5. Click the main currency in which the item will sell.
6. Base Price: Every item should have a Base Price which is the common selling price for an item in your stores.

Enter this price under the QTY 0 (Quantity 0) column. Do not use a currency symbol or comma.

7. If desired, enter price levels (for example, Alternate Price n) that can be assigned to different locations.

To assign a location to use a price level, such as Alternate Price 1, select the level from the Location record using the field POS – Price Level. Each item sold in the location will use that level to determine the price.

8. If you sell the item using different currencies, select the Currency, and then enter the Base Price and other prices.

9. Click Save.
