When you add or edit a client, there is an option to determine the currency that they get billed in for fulfilment activity. To do this:
Additionally, the currency setting also impacts Advanced Shipping Notices (ASNs) and related transactions, ensuring consistency in financial and operational workflows.
Click Clients then Overview.
Find the client.
Next, click Actions then Edit.
Click the Defaults tab.
Use the CurrencyId drop-down and select the required currency.
By default, this will be set as GBP £.
Finally, click Update.
Invoice data will now be displayed in the desired currency. Moreover, ASNs linked to the client will also automatically use the Default Currency, ensuring uniformity in all transaction records and financial reports.
