Set up markets

Define the regions you sell into, each with its own currency, rounding rule and the countries it serves, and link a domain to one.

A market is a region you sell into, with the currency its shoppers expect and a rule for how prices round in it. One market is marked primary and is the fallback for any visitor a domain does not place somewhere else.

The Markets screen listing four markets: United Kingdom marked Primary and Active on GBP with one country and a domain, European Union Active on EUR with nine countries, Ireland Active on EUR with one country, and North America Inactive on USD with two countries. The first three show their rounding rule. — One market per region, each with its currency, countries and rounding.

Create a market

Open Storefront Settings and select Markets.
Select Market.
Enter a Name, such as Ireland. Leave Slug empty to have one generated from it.
Choose the Currency and a Price rounding rule.
In Countries, enter two-letter country codes separated by commas. The line underneath shows what was understood.
Choose a Domain if this market has one of its own.
Select Active, and Primary market if this is the fallback, then select Save.

The rounding rules

No rounding: The converted price as it comes, to the currency's own precision.
End in .99: Rounds to the nearest price ending in .99.
Round to whole number: No minor units at all.
Currency precision only: Rounds to however many decimal places the currency uses.

Pick one per market rather than one for the store. A price ending in .99 reads as retail in one country and as odd in another.

Link a domain to a market

The Domain picker on the market form ties a hostname to this market, so a visitor arriving on it sees prices in that market's currency. A domain already linked elsewhere says so in the list, and choosing it here moves it.

Active, inactive and primary

Active: The market is in use. Clear it to stop offering the region without losing its setup.
Primary market: The fallback for every visitor not placed in another market. Exactly one market should hold it, and it cannot be deleted while it does.

Select Edit on a market to change it, and the delete control to remove it. The primary market has no delete control, which is the safeguard against a store with nowhere to fall back to.
