We just started a Monthly Subscription this year. We're now expanding it to non-US currencies (e.g., $AUD).
The challenge is that the amount the customer sees (in $AUD) will vary every month with the exchange rate. So on a $50/m $US subscription, an Australian might be billed $55.32 AUD, then $53.12 AUD, etc. That could really confuse a subscriber and cause them to question the charges.
I have one idea, but looking for other suggestions and feedback:
Charge less than $50 US so that they are always paying less than the list price.( So if it's $50 US/ $56 AU today we charge $45 US so they almost always pay less than the list price of $56 AU)
Have a note in the receipt that says:
Your Monthly Charge will vary slightly due to [Standard/public*] Exchange Rates.
The monthly charge appearing on your credit card statement will vary due to changing exchange rates but will usually be less than the list price.
We bill in $US but that charge is converted to your local currency and that exchange rate varies by month. We have discounted your price by $5 (US) so that, while your payment amount will vary with currency fluctuations, it means you'll normally pay less than the list price."
(I'd word it more concisely).
*I need a better word here. Something that conveys that we're not just pulling the exchange rate out of thin air, and that it's the standard amount.
Just put a note "All prices are in USD".
I am sure I speak on behalf of other Aussies when I say "we understand exchange rates, it's ok".
Down the track you can set up your system to have different prices for different currencies and actually accept payment in those currencies, but it's tricky and expensive so don't worry for now.
You aren't inventing the wheel here, don't make it a bigger deal than it needs to be.
Its not clear if your prices are listed in AUD or USD?

Two alternative options
Fix prices for all currencies. This way you are the one taking all the risk related to currency fluctuations. You don't want your customers to worry about currency swings, so offer them a fixed price in domestic currency (your product might be very sensible to prices, what means that small change in price could mean significant decrease of sales volume)
You can never really know for sure what will happen on currency markets, so approach with prices in local currency can have both, positive or negative effect on your USD income. However if you evaluate, that with this approach, you are too heavily exposed to FX risk, you should condsider implementing some additional mitigation instruments. More about these you can find out by searching for "FX risk exposure", "hedging", "FX risk mitigation strategies"...
