Currencies
How a Startup prices, charges and books in more than one currency, from a Price per Market to conversion at settlement and one set of books.
A Startup prices each Market in that Market's currency and charges buyers in it. Stripe converts the money once, when it settles, and the Ledger keeps one set of books.
A price per market
An Offer holds one amount per Market. Market.enter opens a Market: Prices in its currency, the Site in its languages, its legal rows woken.
A note-taking app sells at $29 in the US and £25 in the UK. Those are two amounts on one Offer, set on purpose, never a converted dollar price.
The buyer sees the number on the page and pays exactly that. A move in the exchange rate never changes it; change a Market's amount the way you change any Price.
What the buyer pays and what lands
The charge runs in the buyer's currency, so their statement shows £25. Stripe converts it to the account's settlement currency as it settles, at Stripe's rate that day. The conversion cost passes through at cost as its own Entry, beside the charge's platform fee (how fees work).
A refund returns the original £25 to the buyer. Rates move between the sale and the refund, so the difference posts to the Ledger as a gain or a loss, never to the buyer.
How the books read
Every Entry keeps the amount and currency the money moved in. Statements and Reports read in the Company's home currency, each Entry converted at the rate of the day it posted. Revenue by Market stays visible in both currencies.
Tax and payment methods
Entering a Market wakes the rules that come with it, such as VAT in the UK and the EU. Tax computes it at checkout for the buyer's location, so a UK price is tax-inclusive where UK buyers expect it.
Checkout offers only the payment methods the buyer's Market accepts, such as bank debits across the EU. Ask your agent to "sell in the UK", and Sell outside the US runs the steps.
