Slash Financial, Inc., the banking platform built for modern businesses, launched payment processing to enable approved merchants banking with Slash to accept debit and credit card payments from customers. The feature is now available to qualifying users through two launch surfaces: native card acceptance in Slash Invoicing, and a Software Development Kit (SDK) for custom web checkout and payment flows.

The modern banking landscape frequently forces businesses to stitch together a business account, cards, invoicing, payment processing, and accounting tools, leading to incomplete or piecemeal understanding of the business’s financial health. Payment processing brings the entire operational lifecycle of payments inside a business’s Slash account, delivering a complete financial picture and more operational control.

Through payment processing, approved merchants can create a Slash invoice, enable card payment, and view the entire customer payment flow. They can also develop a custom merchant checkout using the Slash SDK, view invoice and SDK-originated payments in the same dashboard, issue partial refunds, track processed funds into Slash accounts and business spend, and receive a payment’s fee breakdown and connection to the appropriate invoice or receivables context.

“Operating a business in today’s environment requires complete visibility into the entire financial lifecycle,” said Andy Jiang, Head of Product at Slash. “Slash payment processing is designed to help increase that visibility and fill one of the blind spots that so many businesses today face in a consumer landscape dominated by credit or debit card payments.”

To power the underlying infrastructure, Slash is partnering with Whop to launch its payment processing feature. Whop will support merchant onboarding, payment execution, settlement, and other processor workflows, allowing Slash to focus on the merchant-facing application, payments dashboard, refunds, payouts and other key elements of the merchant experience to deliver end-to-end payment acceptance without building every regulated layer of the card-processing stack from scratch.

“Each product and service that we launch is developed with the goal of becoming the financial operations system that businesses can rely on,” said Victor Cardenas, co-founder and CEO of Slash. “Partnering with Whop enables us to deliver a reliable payment processing platform for our users that allows them to focus on running their business, and we are excited to see how this partnership unlocks true operational control for entrepreneurs and established businesses alike.”

Payment processing is initially available to businesses operating in e-commerce, telehealth, software, and service agencies in spaces such as marketing, advertising and consulting.
