Rule #1: Quote in the client's currency, control in yours
Selling in the buyer's currency (USD to American, EUR to European) eliminates YOUR friction: round prices, no conversion surprises on your card, more sales conversion. The cost is that the exchange rate variation becomes YOUR issue — and that is why your system must record each operation in both currencies: the currency of the document and your base currency.
The classic Excel mistake: recording the sale of 1,000 USD "as $18,500 MXN" at the exchange rate of that day, and never updating again. When the payment arrives weeks later at another exchange rate, the difference — for or against — disappears from your numbers instead of appearing for what it is: exchange profit or loss.
International prices: it is not multiplying by the exchange rate
- Price by market, not by conversion: your $500 MXN product is not "worth" $27.03 USD — it is worth what your market will support: maybe $34.99. Round up to psychological prices of each currency.
- Includes channel costs: international gateway commission (usually higher), conversion, international shipping and destination tariffs when applicable.
- Update for policy, not panic: define threshold (e.g. if the exchange rate moves ±5%, you review prices) instead of chasing the market daily.
- Beware of arbitrage: if you sell the same thing noticeably cheaper in one currency, customers will find it. Maintain reasonable consistency between markets.
Collecting internationally: options and real costs
For a LATAM SME, the practical routes: payment gateways with international processing (the client pays with their card in their currency and you receive in yours - typical commission 4-6% with conversion included), international transfers for B2B of high tickets, and collection platforms for services/freelance.
The right questions when choosing: in what currency do they deposit you and at what exchange rate? How long does it take for the fund to arrive? Is the conversion commission visible or hidden in the spread? That invisible spread of 1-3% is where the most margin is lost without seeing it.
The well-mounted multicurrency operation
A true multi-currency system does this without you thinking about it: every quote, order and invoice in the customer's currency with its registered exchange rate of the day; your reports and accounting in your base currency; the exchange difference calculated only at the time of payment; and prices by market managed from a single catalog.
Aura operates multi-currency of origin: currencies per client and per order with automatic exchange rate, collections with Aura Payments, and consolidated reports in your base currency — so that selling abroad is growth and not a second improvised accounting system. Try 14 days for $14 USD.

Should I open a bank account in dollars?
If you charge USD regularly, it helps: you receive without forced conversion and YOU decide when to switch. Many banks and fintechs in the region offer USD accounts for SMEs. For small volumes, the automatic conversion of the gateway is sufficient at the beginning.
How do I invoice a sale in foreign currency?
In Mexico, the CFDI supports foreign currency by indicating the currency key and the exchange rate on the day of issue. VAT and taxes are calculated on the equivalent. Your system should do it automatically — by hand is a sure source of errors.
What is exchange profit or loss?
The difference between the value of your currency when billing and when collecting. You invoiced 1,000 USD at 18.50 and collected at 19.10: you earned $600 MXN in exchange (and vice versa, you lost it). Accountingly, it exists and is taxed; your system must calculate it itself.
Is it worth selling internationally as an SME?
If your product or service travels (digital, services, exportable niche), yes: you diversify the risk of your local economy and access tickets in hard currencies. The cost of entry in 2026 is low — the real barrier is operating orderly, not technology.
