Can stores run in multiple currencies and languages for a network across countries?

Yes. Stores present in the buyer's language and currency, price lists understand both, and settlements reconcile in the currency each party is paid in.

A store carries a locale and a currency. Product names, category labels and checkout copy render in the store's language, and prices come from a price list that holds a value per currency rather than converting at display time, so a network prices deliberately in each market instead of letting an exchange rate set the shelf price. Tax and VAT are handled per market. At settlement each party is paid in its own currency into its own connected account, with a statement showing the orders behind the number. Purchase orders still raise on the account numbers you hold with suppliers in that region.

The alternative is a separate tool per country, with a separate catalog, separate price maintenance and separate reporting, joined into a spreadsheet at month end. Or a single English store that asks buyers to convert in their heads, which quietly loses orders at the last step of checkout and never tells you why.

This is for networks that cross borders: franchise systems with locations in several countries, buying groups with international members, distributors serving a customer with offices in more than one market. One network can sell in Dallas and Antwerp from one cockpit, and HelloPrint is integrated for print and packaging across Europe. The caveat: adding a language means somebody reviews the product copy for that market. The system renders it; it does not invent your merchandising voice.
