Currency and pricing for international customers: which currency to quote, how to answer "how much in my currency", payment methods by region, fees, and what an AI agent should and should not calculate

The moment you sell abroad, every price has two numbers: yours and the one the customer's bank will charge. Quoting the wrong one, or a conversion that is a week old, starts a dispute over a few percent that costs the whole sale. The answer is to pick a base currency, be explicit about conversions, and let the bank do the arithmetic.

Quick answer

Quote all prices in one base currency (usually USD or EUR for a worldwide audience, or your local currency for a mostly local one), state it on every price, and when customers ask for their currency give an approximate conversion with the date and the line "your bank sets the final rate and may add a fee". Offer payment methods by region (card link for most, local transfer where you have an account), state whether tax is included, and keep one price list. An AI agent follows these rules if you write them in: it quotes the base price, gives a dated approximation only if you allow it, and never promises a rate. ReplyKit answers in the customer's language from one price list.

Choose a base currency Answering "how much in my currency"Payment methods by region Tax and totals FAQ

Choose a base currency

USD or EUR for a worldwide audience; customers everywhere understand them and card networks convert.
Local currency if most customers are local and a few are abroad; quote it and add the conversion caveat.
Two price lists only if you genuinely price differently by region, and then keep them separate in the knowledge base with the region named on every line.
State the currency on every price: "$49 USD", not "$49". Dollars exist in a dozen countries.

Answering "how much in my currency"

Approximate, dated

The price is $49 USD. That's roughly {amount} {currency} at today's rate ({date}); your bank sets the exact rate and may add a small fee.

No conversion offered

Our prices are in USD; your card is charged $49 and your bank converts at its rate. Most customers see a difference of a percent or two.

Local price list exists

For customers in {region} we price in {currency}: {amount}. That's the amount you'll be charged.

Decide which of these your agent uses and write it into the instructions. The safest for most businesses is the second: no conversion at all. If you allow approximations, update the rate note weekly and keep the date in it; the agent must never present a conversion as the charge.

Payment methods by region

A region-by-method note: "Worldwide: card via {link}. {Region}: bank transfer to {account}. {Region}: {local wallet}." The agent answers "how do I pay from {country}" without you. Mention fees honestly ("international transfers may incur bank charges on your side"). For payment verification and holds, see taking payments on WhatsApp, which applies to any country's methods.

Tax and totals

State whether prices include sales tax or VAT, and for whom ("prices exclude VAT; EU customers see VAT at checkout").
For cross-border goods, duties are the customer's; the wording is in the international customer FAQ.
The agent should total only what your price list defines (price plus listed shipping) and never estimate taxes or duties.
Haggling over a few percent of conversion is handled like any other haggling: hold the base price politely; see handling haggling.

Frequently asked questions

Which currency should I quote in?

One base currency, stated on every price: USD or EUR for a worldwide audience, local if most customers are local.

Should the AI agent convert prices?

Either not at all, or approximately with the date and a line that the bank sets the final rate. Never as the amount to be charged.

How do customers pay from abroad?

A card link works everywhere; add local transfer or wallet options by region in a note the agent quotes.

Are taxes included?

State it explicitly for each region. The agent should never estimate taxes or duties.

What if a customer disputes the conversion?

Point to the base price and the caveat; the bank's rate is outside your control and the agent should say so.
