The social media platform has take another step towards becoming a commerce business with the new development this week, which would let users store payment information to make purchases more quickly.
As reported by The Verge, Instagram will charge retailers - which will initially include the likes of Nike, Adidas, H&M, Dior, Michael Kors and Prada - a selling fee.
If an item is eligible for in-app checkout, it will now have a blue "Checkout on Instagram" button, which will ask the user to provide their email address so the seller can complete the order.
From there, the user enters delivery information and chooses a payment method, with an opportunity to review details before the order is placed.
The company said: "Checkout is just one part of our long-term investment in shopping. We're excited to introduce even more ways for people to enjoy shopping on Instagram this year."
Although payment information stored with parent company Facebook will only be used on Instagram there's a possibility Facebook would let people use these elsewhere in its collection of apps and services.
As it stands, the company insists it won't share payment information with retailers or other users.
