# Fishbowl: Cannot change customer currency (orders exist)

> Once sales orders are created for a customer, their currency setting is locked and cannot be changed.

## What it means

Once you've created sales orders for a customer, Fishbowl locks their currency to prevent data integrity issues. If orders exist in one currency and the customer record switches to another, the transaction amounts and aging summaries would no longer match the underlying order data.

## What to check

- Verify the customer has existing sales orders by checking their order history
- Confirm what currency those orders were created in
- If you need future orders in a different currency, consider whether a separate customer record would better serve your needs
