IFRS 15, 'Revenue from Contracts with Customers,' has brought several key improvements in terms of consistency and comparability in revenue recognition across industries and international borders. Here's how:

1. Single Standard: Prior to IFRS 15, revenue recognition practices varied across industries and regions due to different interpretations and applications of previous standards. IFRS 15 replaces multiple revenue recognition standards and interpretations, creating a single, comprehensive revenue recognition model applicable to all contracts with customers (with some exceptions).
2. Clearer Guidance: The standard provides a robust framework for recognizing revenue, with explicit guidance on handling specific scenarios such as contract modifications, variable consideration, and multiple performance obligations. This helps reduce the scope for differing interpretations and practices.
3. Greater Consistency: The five-step model introduced by IFRS 15 provides a structured approach to revenue recognition, leading to more consistent accounting for transactions across different industries and companies.
4. Enhanced Disclosure Requirements: IFRS 15 introduces extensive disclosure requirements, ensuring that companies provide detailed information about their revenue from contracts with customers, including disaggregation of revenue, information about contract balances, and the transaction price allocated to the remaining performance obligations. This transparency allows for better comparability between companies.
5. International Alignment: IFRS 15 was issued jointly with the US Financial Accounting Standards Board's (FASB) Topic 606, meaning the principles are largely aligned with those under US GAAP. This improves comparability of financial statements globally, especially for multinational corporations that report under both IFRS and US GAAP.

By promoting consistency and comparability in revenue recognition, IFRS 15 enables investors and other stakeholders to make more informed decisions and comparisons across different companies and industries worldwide.
