Set a base currency in Katana to standardize all financial transactions and reports. Your base currency is used across sales, purchases, and inventory valuation, ensuring consistency in financial data.
How to set your base currency
It’s best to set your base currency before you start working with sales orders, purchases, or integrations.
Go to Settings > General.
Select your preferred currency from the dropdown menu.
This currency will now be used for:
Sales prices
Manufacturing costs of products and materials
Stock values
When base currency becomes locked
Once certain actions are taken, you can no longer change the base currency. This is to ensure historical consistency — Katana cannot perform bulk conversions of past data.
Your base currency will be locked if any of these conditions apply:
You connect Katana to an e-commerce store (e.g. Shopify, WooCommerce) with a different store currency.
You connect Katana to an accounting platform (e.g. Xero, QuickBooks).
You create at least one sales or purchase order in a foreign currency.
You add at least one customer or supplier with a different default currency.
Important notes
If you need to change your base currency later, you must first resolve all of the conditions above.
If you’re only testing Katana, you can perform a full data wipe to reset your base currency. (Not recommended for live accounts.)
