Prospective Twitter Inc (NYSE:TWTR) owner Elon Musk said the website and app may charge a nominal fee for commercial and government users.
Using the social media platform he liked so much he bought, he said Twitter "will always be free for casual users", but companies and government departments will "maybe [be charged] a slight cost".
Musk added in another tweet: "Ultimately, the downfall of the Freemasons was giving away their stonecutting services for nothing."
"Some revenue is better than none!" Musk wrote in a tweet.
After the South African-born billionaire added Twitter to his cart for US$44bn he said he wanted to enhance the platform with new features, make the algorithms open source, and increase human trust by defeating spambots.
News of the nominal fee have appeared after Musk told the banks that are funding the Twitter deal that he will focus on finding ways to monetise tweets, with talks also being held with large investment firms and other high net-worth individuals to help fund the deal.
Musk told banks he would work to slash the company's costs by cracking down on executive and board salaries, which he claims will save around US$3mln annually, and monetise tweets, Reuters reported.
The existing Twitter Blue account offers Twitter's most loyal customers access to premium features and app customisation for a small monthly fee.
Last month, even before reaching a deal with Twitter, Musk suggested a few changes like slashing the price of the Twitter Blue subscription service, currently at US$2.99 a month, banning advertising, and letting users pay in Dogecoin.
Since its inception in 2006, Twitter has struggled to make money, only reporting its first quarterly profit 12 years later in February 2018.
Since then, the microblogging platform has added several features designed to help the company earn more money.
In the United States, Canada, Australia, and New Zealand, Twitter Blue is available on iOS, Android, and the web.
