# Introduction - Payments by Upflow

> Discover Payments by Upflow, the B2B online payments stack built on Stripe infrastructure that powers card, ACH, SEPA, and BACS collection in customer portals.

At Upflow **we believe that B2B payments will undergo a profound online (r)evolution in the next 10 years**, similar in magnitude to what B2C and e-commerce have experienced over the past 2 decades.

We are building the infrastructure, tools and products to both embrace and facilitate this transition over to digital payment flows helping our Merchants, like you, be ahead of the curve — not laggards.

We believe **payments are an integral part of your global customer experience** , often neglected or off-brand — mostly due to a technology problem.

That's why we're building useful & deep online payments functionalities tailored for B2B, which we collectively refer to as **Payments by Upflow** ("PbU"), enabling you to dramatically improve cash inflow while providing a delightful experience to your customers.

Welcome to the new era of B2B payments!

*Note: PbU is built on top of Stripe's best-in-class, white-labeled infrastructure — like Shopify or Salesforce. Stripe abides by the highest security standards in the industry, including [PCI Service Provider Level 1](https://docs.stripe.com/security).*
