Living the digital nomad life is a dream, but cross-border finances can be a nightmare.
Currency Confusion
Always invoice in the currency of your Client or a standard reserve currency (USD/EUR). If you invoice in Thai Baht to a US client, they likely cannot process it.
Tax Residency
Just because you are traveling doesn't mean you are tax-free. You generally owe taxes to your country of citizenship (US) or your country of tax residence (where you spend 183+ days). Your invoices serve as proof of income for these authorities, so keep them organized in the cloud.
