Modern Multi-Currency Tools for Small Business in Singapore

For small businesses in Singapore dealing with international clients or suppliers, managing multi-currency can be a source of frustration and headaches. Here’s why and how you can leverage technology using tools like Xero and Airwallex to make dealing with multi-currency a breeze.

Multi-Currency in Business Operations

Why would you need to use foreign currencies and what are some of the issues you need to consider?

  1. More Options for More Customers: Offering ways for customers to pay in their preferred currency can help you get paid faster.
  2. Reduced Currency Exchange Fees: By holding and receiving payments in multiple currencies, businesses can reduce the costs associated with currency conversion.
  3. Improved Cash Flow Management: Paying suppliers in a foreign currency may be quicker and easier when you already have that same currency in a foreign currency bank account without worrying about the day to day fluctuations in conversion rate.
  4. Compliance and Simplification: In Singapore, GST registered businesses issuing foreign currency invoices must show conversions in SGD to comply with the Inland Revenue Authority of Singapore (IRAS) requirements. Having an accounting system that automates these conversions can save time and reduce errors.
Choosing Your Base or Functional Currency

Another decision you'll need to make as a business owner or manager for compliance is to determine your base currency.

The base currency should reflect the primary economic environment in which your business operates. For most Singaporean businesses, this will be the Singapore Dollar (SGD), but for those with significant operations abroad, another currency might be more appropriate.

This decision impacts how you report your finances and should align with FRS 21, the Financial Reporting Standard on Functional Currency.
