The online store will serve as part of the micro computer's Raspbian operating system, playing host to both free and premium applications for the machine.
A 'tip jar' scheme allows customers to make donations based on what they believe each app is worth, but programmers can also sell their wares via a secure payments system.
"Our driving aim has always been to use Raspberry Pi to encourage and introduce a generation of children to programming and creative computer science," said Raspberry Pi Foundation's Eben Upton.
"By now enabling Raspberry Pi users of all ages to gain critical and commercial success from their work through the new Pi Store we also believe it will be a powerful incentive for others to get involved and further spread the word."
The Raspberry Pi, a credit card-sized machine developed to spark an interest in grass-roots programming, was released earlier this year.
