How Slash runs a $300M fintech on a finance team of one

Overview

Slash is one of the fastest-growing fintech platforms in the U.S., they are a modern banking product built for the next generation of entrepreneurs. Since its founding Slash has scaled to over $140 million in annual revenue, serving thousands of businesses with a zero-friction banking experience.

Lean by design, Slash has always prided itself on doing more with less. But as the business scaled, its finance function became the biggest test of that philosophy.

The problem

A $300M+ business running on a system built for a start up

As Slash grew past the $300M ARR threshold, the gaps in its legacy accounting setup became impossible to ignore. Reconciling a high volume of daily transactions manually, managing the operational complexity of a fintech operating across multiple payment flows, and doing it all with a skeleton team. It was a setup that didn't scale.

The finance team was spending its time on data entry, manual reconciliation, and chasing down discrepancies, rather than the strategic work that a fast-growing business actually needs from its finance function. Slash needed a system that could handle the complexity of its business without requiring the headcount to match.

The solution

An ERP that runs as lean as the team does

After evaluating its options, Slash moved to DualEntry and went live in 24 hours with its complete accounting suite, historical data intact.

With DualEntry's AI-native automation handling the operational workload, Slash's single-person finance team can now manage the full complexity of a $140M revenue fintech:

• Bank matching and reconciliation handled automatically, cutting out hours of daily manual work across thousands of transactions
• Full GL, AR, AP, and reporting in one system, purpose-built for the nuances of high-transaction, fast-growth businesses
• NextDay Migration: full historical data migrated from the previous system in 24 hours, with zero implementation fees

Most companies at $140M have a finance department. Slash has a finance person. The difference isn't headcount, it's that their AI ERP actually works.

Results

"Before the transition we had a few open roles for line-level accountants, people in FP&A," said Victor Cardenas, founder and CEO of Slash. "Post-transition, so much of that has been automated that we actually closed these other open jobs."

The one person who stayed is no longer keeping the books. "Our one finance person is now finance leader and can focus all her time on doing very strategic work." DualEntry handles the parts of a fintech close the old ERP couldn't: per-line-of-business P&Ls, generation versus redemption, rewards costs. Every transaction books directly to the ERP instead of being pre-aggregated first. Across tens of thousands of credits and debits a month, the AI runs the workflows that used to take a team of people.

The goal now is to reach a billion-dollar revenue business with a finance team of one. "When we looked at these other newer ERPs, DualEntry was really the only one that didn't feel like a stop-gap," Cardenas said. "There are publicly traded companies on DualEntry. It was super important for us that we worked with a solution that can scale with us."
