Currency Code for Inventory Items

is this possible to add Currency Code for each inventory items
we have some products sell in USD
some products sell in MMK
can you guide us how to use for that case?

Read the Guide: https://www.manager.io/guides/9158. Inventory is always valued in your base currency. If you only sell something to USD-denominated customers, you can enter the figures for USD prices for the inventory item. When Manager autofills prices from inventory definitions, it doesn’t really know what currency they are in; it is only filling numbers.

Can I make a suggestion? You have asked so many questions since joining the forum last month, it seems you are not reading the Guides before posting. The Search function on the Guides page is quite good. You could save yourself a lot of time. See https://www.manager.io/guides/18030.
