Google has changed when it pays revenue to Android app developers, adjusting the timeframe from two days after the end of the month to 15 days.

The company informed developers that the move was down to “new forms of payment” and would allow them to better serve their users and create more revenue opportunities.

However, the change in payment schedule could affect the ability of smaller developers to pay their bills on time and provide a nuisance to larger developers.

TechCrunch speculates that the new form of payment could be a cash balance held within Google Wallet rather than on third-party payment cards, as suggested by leaked information on an update of the technology. This would give users the ability to deposit money from their current account into their Google Wallet, much like the system used by PayPal.

With the leaked information saying cash transfers to Google Wallet could take three to six days to process, the flow of transactions in Google Play could be slowed, affecting when Google can pay developers.

Users can currently buy apps and make in-app purchases using Visa, MasterCard, American Express and Discover via Google Wallet integration. Direct operator billing is also available in some markets.
