At Yvonne Sullivan CPA LLC, we believe that the best outcomes come from strong alignment between your business needs and the support we provide. Our approach is designed for business owners who want confidence in their financial systems, active involvement in their accounting workflows, and a structured foundation to support informed decision-making and growth.
We work with businesses in the startup and growth stages that are actively operating and whose financial systems are still forming or evolving. Our ideal clients understand that organized books, real-time access to financial data, and systems that support decision-making are foundational to long-term success. During our Discovery and Onboarding process, we explore your current systems, registration structure, revenue model, industry demands, and mindset so we can ensure a mutually strong fit—one where we can truly add value rather than simply perform transactional tasks.
Below is an overview of the characteristics and criteria we typically align with. This helps you self-evaluate whether our services are the right match for your business before moving forward with a consultation or engagement.

Our clients are generally in the Startup and Growth stages of the business life cycle. These are actively operating businesses, typically within their first five years, where financial systems are still forming or evolving and where clear accounting and guidance can meaningfully support informed decision-making.
🚫 We typically do not engage businesses in the Seed, Maturity, and Decline stages of the business life cycle. Exceptions may be considered on a case-by-case basis when there is strong alignment.
Our clients are formally registered at the state level under one of the following structures or registrations. Federal tax treatment must align with our engagement model, as noted below.

We are best aligned with businesses whose operating models are straightforward and scalable. Our preferences reflect the types of businesses where clear accounting, reporting, and guidance can provide the most value.
Service-Oriented Businesses: Businesses that generate revenue through the delivery of services rather than complex production or distribution models.
Project-Based Businesses: Businesses that perform work by job, project, or engagement, where revenue and costs can be tied to defined scopes of work.
Job-Costed Businesses: Businesses that benefit from tracking labor, materials, and other costs by job or project to better understand profitability.
Progress Billing Models: Businesses that bill clients in phases, milestones, or percentages of completion, commonly seen in construction and skilled trades.
Cloud-Based Accounting: Businesses that operate using cloud-based accounting systems and digital workflows, allowing for timely reporting, collaboration, and efficient support.
Social Enterprises: Mission-driven, for-profit businesses that balance purpose and profitability, including Benefit Corporations or values-aligned companies operating with clear financial objectives.
Cash Basis or Hybrid Accounting: Businesses that operate effectively on a cash basis or hybrid approach, where simplicity and clarity in reporting are prioritized.
AI-Oriented Businesses: Businesses whose owners are open to adopting and using AI-enabled tools and features to improve productivity, efficiency, and decision-making, including leveraging AI capabilities within cloud-based accounting and reporting platforms.
🚫 We are less aligned with businesses that require full accrual-based accounting and highly complex operational models that are outside the scope of work (or offering).
Our clients generally have ten or fewer employees and contractors combined. This allows us to provide hands-on support while keeping payroll, job costing, and reporting manageable. Exceptions may be considered on a case-by-case basis when there is strong alignment.
Our clients typically generate less than $5 million in annual gross revenue. Must be actively operating with consistent, ongoing revenue, as our services are designed for companies that can sustain a professional accounting relationship.

🚫 We currently do not engage these industries: Hospitality, Restaurant/Bar, Manufacturing, Telecommunications, Wholesale, and industries that require specialized trust, insurance, or regulatory accounting (such as Legal).
The most successful engagements are built on mutual respect, accountability, and a willingness to learn. Our ideal clients are business owners who are curious, open-minded, and committed to understanding the financial side of their business — even when it feels unfamiliar or challenging.
We work best with clients who value clear communication, follow through on requests, and view financial guidance as a collaborative process rather than a transactional service. Growth requires honesty, adaptability, and trust, and we look for partners who are prepared to engage thoughtfully, ask questions, and take ownership of their decisions.
If you are motivated to build strong systems, receptive to guidance, and interested in long-term stability rather than short-term fixes, you are likely a strong fit for our firm.
