In Portland, Maine, Slate CPA (formerly Slate Consulting) is proving that accounting firms can grow quickly without giving up stability. Founder Mark Booten has built a business focused on acquiring established practices, helping retiring owners transition, and giving clients seamless continuity of service.
With the Revenued Flex Line, Mark can access working capital based on business performance instead of credit scores or collateral. That flexibility lets him hire ahead of demand, invest in technology, and keep acquisitions moving forward on his own terms.
How it started
After two decades in both public and private accounting, Mark saw a gap in the market. Many small firms had loyal clients but no clear succession plan. In 2022, he launched Slate CPA to provide a solution that worked for everyone: a fair exit for owners, a secure future for their clients, and a growth opportunity for his team.
He began by acquiring established practices that shared his values. Each acquisition gave him new insights into integration, operations, and client management. Step by step, Slate turned that experience into a repeatable model for sustainable growth.
How it's going
In just two years, Slate has completed six acquisitions and has another in the works that could double the size of the firm. That kind of growth takes planning and precision. Cash flow, hiring, and technology upgrades all need to happen before new revenue arrives, and that can create pressure for any service-based business.
With support from Revenued, Slate doesn’t have to slow down. The Revenued Flex Line allows the team to draw funds as needed and pay only for what they use. The funding process is fast, straightforward, and based on real business performance. It gives Mark the breathing room to make confident decisions instead of waiting on traditional approvals.
He’s also investing in automation and advanced accounting systems to strengthen efficiency across his expanding network. Slate CPA has become a model for how small professional service firms can scale with intention and stay true to their clients.
Why Revenued
Traditional financing often requires hard assets or personal guarantees. For service businesses like Slate, that can make growth nearly impossible. Revenued looks at things differently.
The Revenued Flex Line provides business funding based on revenue, not personal credit. There are no origination, maintenance, or draw fees, and accountholders only pay for the working capital they need. Decisions can come in as little as one hour, and funds are usually available within 24 hours of approval.
Mark uses his Flex Line to hire staff before tax season, invest in new software, and prepare for acquisitions. Funds can be deposited directly into the business account or accessed through the Revenued Business Card for day-to-day needs. As Slate’s revenue grows, its spending limit increases, creating more room to act on new opportunities.
About the Accounting Industry
The accounting industry is undergoing major transformation as firms adapt to technology, talent shortages, and a wave of retiring CPA owners. Companies like Slate CPA are capitalizing on this shift through strategic acquisitions, providing value to outgoing firm owners and stability for their clients. For fast-growing firms, cash flow management is critical, particularly when hiring staff ahead of peak tax season or integrating newly acquired practices. Flexible funding solutions give accounting firms the ability to scale quickly, invest in technology, and position themselves for long-term growth in an increasingly competitive market.
