Payments startup (and PayPal challenger) Stripe has just announced a new partnership with Bigcommerce, an e-commerce platform provider.

The integration of Stripe Connect will let Bigcommerce merchants — all 35,000+ of them — collect online payments directly from their own websites, no redirects required for checkout.

In addition to creating better experiences for the end user, Connect lets Stripe-using merchants set up and start using their online payments in minutes instead of weeks.

Stripe Connect for Bigcommerce launches today in the U.S. and Canada; other countries will be supported soon. Connect merchants will be able to accept most major credit cards, including Visa, MasterCard, American Express, JCB, Discover, and Diners Club.

Stripe charges merchants 2.9 percent plus $0.30 for each successful transaction, and discounts are available for merchants with high volumes of transactions.

Other Stripe clients include Lyft, Foursquare, Wufoo, Mixpanel, Grooveshark, and Pebble.

Stripe was founded in 2011 and is based in San Francisco. The startup’s investors include PayPal cofounders Peter Thiel, Max Levchin, and Elon Musk, Sequoia Capital, and Andreessen Horowitz. To date, the company has raised $40 million in two rounds of institutional funding and a $2 million seed round in 2011.
