Google announced today it's expanding the user choice billing program for Play Store — which lets users choose alternative payment systems for in-app purchases — to India, Australia, Indonesia, Japan, and the European Economic Area. The company is calling all non-gaming developers globally to apply for this program, and if they qualify, they can use third-party payment systems in the above-mentioned regions.

The search giant introduced a similar policy for non-gaming developers and users in the EEA region in July. The new guidelines are an extension of that. The company gave a 3% discount on fees for developers using third-party billing in the EEA region. In the new announcement, the firm said "reasonable service fees will continue to apply," but didn't mention any numbers. The company said it will reveal more details about that in the coming weeks and months.

This information is critical for a lot of developers as the percentage cut Google takes will determine if they want to go through the hassle of switching payment processors.

The company said that more than 99% of developers on the Play Store qualify for 15% or lower fees — but the top 1% of developers generate quite a lot of revenue on the Play Store. Google takes a 15% cut from the first $1 million from any developer annually. It then charges 30% after developers' first million-dollar earnings for the year. Some developers who qualify for the Google Play Media Experience program — which includes apps offering books, audio, and video — pay as low as 10% fees.

While this new expansion includes some of the largest Android markets like India and Indonesia, it ignores the U.S. market where lawmakers are exploring rules that aim to curb Apple and Google's monopoly over app stores. In July, the firm agreed to a $90 million settlement with U.S.-based developers over the issue of Play Store fees.

“Android has always been a uniquely open operating system, and we continue to evolve our platform and increase the choices available to developers and users, while maintaining our ability to invest in the ecosystem. We will be sharing more in the coming months as we continue to build and iterate with our pilot partners," a Google spokesperson said in a statement.
