Ribbon is one of several payments startups drawing new attention that is focused on one thing: removing the irritating qualities that come with purchasing things online. We’ve written about Ribbon before, namely how the company wants to let people make purchases just by clicking a link. And on Wednesday, the company plans to announce an even simpler way to buy: through Twitter.

Users on Twitter who come across merchants selling items through Ribbon will be able to tap the tweet to expand and complete a purchase without ever leaving Twitter. Ribbon had previously optimized its links so that users could purchase items through both Twitter and Facebook, but recent updates to Twitter’s Cards technology will extend this capability even further.

The idea? “Let’s just keep the buyer where they already are,” CEO and co-founder Hany Rashwan told me. “It’s a one-page check-out.”

In a demonstration, Rashwan showed me how to tap a tweet with a Ribbon link embedded, enter my credit card information, and hit purchase, all without leaving the expanded tweet. He said they’re working on improving the service so that once users make a purchase on Ribbon through Twitter, they won’t have to enter their credit card information a second time.

“We’re utilizing a part of the new cards technology,” noting that the company has also been supporting in-stream purchases on Facebook for a few months, and that the company has “tens of thousands” of merchants selling, although he would not disclose specific numbers.

As we wrote previously, Angelpad alum Ribbon has built its own payment system that lets it avoid fees and sets it apart from competitors, many of which use companies like PayPal or Stripe for credit card processing. The company is also updating its fees for merchants selling through Ribbon — it will now charge 2.9 percent plus $0.30 per transaction, rather than the previous 5 percent plus $0.30 per transaction.

As we watch apps like Ribbon start to incorporate payments into Twitter’s stream, it’s easy to see why Twitter would want to expand the different types of Cards technology it offers, and how the company might start to allow transactions like Ribbon payments to happen on the site — potentially benefiting both Twitter and the payments companies.

Ribbon, a new stealth startup with seed funding from Draper Associates, is now trying to get into the act with a commerce tool that it believes is even more flexible for sellers. Like Gumroad, it allows people to create a link that allows customers to buy a product, either digital or physical. And like Chirpify, which works on Twitter and Instagram, or Soldsie, which enables sales through Facebook, Ribbon is also designed to work well within existing social channels.

Using one URL, Ribbon can customize the experience for each platform. So if a person clicks on a link in Facebook, they can get taken to a Facebook app, where they can enter in their payment info and check-out. In Twitter, which doesn’t have its own app platform, a user will get taken to a special page made for Twitter users. Tumblr and WordPress users can also include their own Ribbon button that pulls up a window inside their site through which visitors can buy from. The service also works with YouTube and Pinterest, so a seller can show a video or a picture of a product or performance and then ask a viewer to purchase afterward.

Ribbon founder Hany Rashwan told me the service has built its own payment infrastructure to handle all credit cards, which allows it to save on interchange fees and pay out to sellers through the mail, wire transfers, ACH transfers and also PayPal. He said that separates it from other competitors like Chirpify, which works through PayPal or Gumroad, which was built using Stripe’s APIs.

He believes that Ribbon is also a more powerful tool for selling on a number of platforms since it can provide a different experience for users based on where they click on a link. And with one account, users can buy from multiple platforms without having to enable Ribbon each time.

“The idea is, selling happens wherever the buyer is. I don’t want the buyer to have to leave the experience they’re on because that hurts conversions, ” Rashwan said.

Rashwan started coding when he was 11 years old and made more than $200,000 as a teenager running advertising-supported fan sites for popular games. He attended Ohio State before dropping out to pursue his startup dreams. The idea for Ribbon came after he and a friend complained about the check-out process for many online transactions, which can often take people out of their original website. What began as a way to simplify the checkout process become Ribbon.

The service, which has been been in private alpha for the last month, charges 5 percent + 30 cents per transaction. That’s a little more expensive than Gumroad, which charges 5 percent + 25 cents per transaction.

I’m excited to see more selling tools emerge. We’re creating a new economy that allows anyone to become a merchant. Platforms like Etsy and Shopify have made it simple to become an online seller. But services like Ribbon, Gumroad and Chirpify are making it even easier for anyone to start doing business. This is also important as people spend more time on mobile devices. With simple tools like this, it makes it easy for someone to make quick impulse buys from a mobile device.
