Twitter’s long-awaited plan to let its users make purchases right from a tweet is nearing, and payments startup Stripe will have a role in the business, multiple industry sources tell Re/code. Later this year, Twitter is expected to unveil buttons within tweets that say “Buy” or some variation of the word; after clicking on the button, shoppers are expected to be able to enter in payment and possibly shipping information without leaving Twitter’s service. Sources say that businesses that want to sell products or services within tweets are being instructed to sign up with Stripe to process payments on their behalf. While Stripe is believed to be Twitter’s only payments partner now working on the e-commerce business, it’s not clear whether that will remain the case over the long haul.
