Each plan can include only one base charge. To add a base charge: 1. Enter the charge amount in US dollars for each available billing period. 2. (Optional) Define prices in other currencies later using Stigg’s [price localization](/documentation/price-localization/price-localization) capabilities. 3. Click **Add** to save the charge.
