Congrats on starting your online business. Dealing with multiple currencies can definitely be a challenge. I recommend checking out FXConvert https://fxconvert.net/ . They have a great currency calculator that simplifies the process of converting between most global currencies. For example, if you’re converting Australian dollars to Indian rupees, you just enter the amount, and the tool provides the current conversion rate and amount. They update the rates daily, so you always get the latest info. It’s been really helpful for managing my international transactions. Give it a go!
