Best invoicing software for businesses sending international invoices

Running a small or medium-sized business (SME) is already a juggling act. Throw international clients into the mix and suddenly you’re not only managing sales and expenses—you’re also figuring out how to send an invoice abroad, deal with fluctuating currencies, and comply with VAT rules. That’s where choosing the best invoicing software makes all the difference.

Today’s SME invoicing tools go far beyond creating simple bills. They help you manage multiple currencies, handle tax compliance, and even automate recurring payments. The right choice can save you hours each week—and protect you from costly mistakes.

In this guide, we’ll walk you through the best invoicing software options for SMEs in 2025, what features to look out for, and how to pick the tool that best suits your business.

Key features to look for in international invoicing tools

Before we get into the tools themselves, let’s talk about what makes a good solution for businesses with global clients.

Here are the must-have features to keep on your radar:

• Multi-currency invoicing: If you’re working with international partners, you need invoicing tools that automatically adjust for exchange rates and let clients pay in their local currency.
• VAT invoicing software: Compliance isn’t optional. Look for tools that generate tax-compliant invoices and let you apply VAT rates correctly depending on your clients’ locations.
• Recurring and automated billing: If you bill customers regularly, automation ensures you never miss an invoice—and you get paid faster.
• Payment integrations: The best tools integrate with online payment gateways so your clients can pay directly via credit card, PayPal, or bank transfer.
• Expense and reporting features: Good online billing software doesn’t just send invoices; it also helps track who’s paid, generate reports, and forecast cash flow.
• Ease of use and affordability: As an SME, you want tools that save you time and don’t break the bank.

How to choose the right invoicing software for your SME

With so many options available, how do you actually make the right choice? Here are a few tips:

1. Start with your client base: If most of your customers are abroad, prioritise international invoicing tools with strong multi-currency features.
2. Consider compliance needs: If you’re VAT registered, make sure the software doubles as reliable VAT invoicing software.
3. Think about integrations: Already using an accounting tool or CRM? Choose an invoicing app that integrates seamlessly.
4. Balance cost and features: Free tools like Wave are great for basics, but growing SMEs might need Xero’s advanced features.
5. Test before committing: Most platforms offer free trials—use them to get a feel for what works best.

Remember: invoicing software should make your life easier, not harder. Go for a solution that feels intuitive and saves you time.
