Financial clarity.
Operational momentum.
No full-time executive required.
I help growing businesses gain the financial clarity and operational momentum they need — without the cost of a full-time executive. With 20+ years in accounting leadership, management consulting, and business strategy, I step in where it matters most.
You're in the right place if…
Your business is scaling and ops can't keep up
You need a trusted operator in your corner — not another hire you have to manage
You want financial clarity without a full-time CFO
Your books are a black box and decisions are being made on instinct alone
You need executive-level leadership on a fractional basis
Between hires, at a pivot point, or ready to build the infrastructure to scale
I don't just close the books.
I move things forward.
I step in as a trusted advisor who identifies where systems are breaking down, builds processes that scale, and develops the people around you. Whether I'm stabilizing a month-end close, redesigning an accounting function, or guiding a business through a critical pivot — I operate with the precision of a CFO and the agility of a consultant.
With 20+ years spanning accounting leadership, management consulting, and business strategy, I bring a rare combination of technical depth and strategic perspective to every engagement. Financial, operational, and human — I see the full picture.
I'm Karem Mieses
Fractional Accounting Manager and Operations Leader with 20+ years of experience across accounting leadership, management consulting, and business strategy. I've helped businesses of every size gain financial clarity and build the operational infrastructure to scale.
Born and raised in San Juan, PR — bilingual, detail-oriented, and deeply invested in the businesses I work with. I started my consulting practice in 2002 because I knew there was a better way for growing businesses to get executive-level support without a full-time executive cost.
A few things about me
The rare combination your business needs
Technical depth in accounting. Strategic perspective from management consulting. Hands-on execution from years of business operations. Most advisors have one — I bring all three.
I operate with the precision of a CFO and the agility of a consultant.
Executive leadership.
Fractional cost.
I help growing businesses gain financial clarity and operational momentum without the cost of a full-time executive. With 20+ years spanning accounting leadership, management consulting, and business coaching, I bring a rare combination of technical depth and strategic perspective to every engagement.
I step in as a trusted advisor who doesn't just close the books — I identify where systems are breaking down, build processes that scale, and develop the people around me. Whether stabilizing a month-end close, redesigning an accounting function, or guiding a business owner through a critical pivot, I operate with the precision of a CFO and the agility of a consultant.
My clients don't hire me to maintain the status quo. They hire me because they need someone who can see the full picture — financial, operational, and human — and move things forward with integrity and purpose.
Why I do this work.
I've spent 20+ years inside businesses at the moment things get complicated — when growth outpaces systems, when the numbers don't tell the story they should, when the founder realizes they can't be everywhere at once.
I started my consulting practice in 2002 — because I saw a pattern. Business owners with extraordinary vision, trapped by the operational chaos that growth creates. The books were a mystery. The team lacked direction. The processes existed only in people's heads.
Over two decades, I've stepped into businesses at critical inflection points — stabilizing what was broken, building what didn't exist, and developing the people who would carry it forward. Every engagement is different, but the mission is the same: move things forward with clarity, integrity, and purpose.
I bring my full self to this work — bilingual, detail-oriented, and deeply invested in the success of every organization I partner with. I don't just advise from the outside. I step in, I own the outcomes, and I build something that lasts.
That's the difference between a consultant who tells you what to do and a fractional executive who actually does it with you.

Let's talk about what your business actually needs.
I don't offer cookie-cutter packages. Every engagement starts with a conversation about where you are, where you're going, and what it will take to get there.
Executive-level operations & finance leadership, on your terms
I work with growth-stage businesses and founders who need fractional support at the leadership level — not a consultant who hands you a report, but a trusted operator who owns the outcomes alongside you.
Fractional COO & Operations Leadership
I step into your business as a part-time Chief Operating Officer — identifying where systems are breaking down, building processes that scale, and developing your team to execute without you in the room. Ongoing engagement, real ownership, and measurable momentum.
What I own:
- Operations systems design and implementation
- Process mapping and workflow optimization
- Team structure, accountability, and development
- Vendor and project management infrastructure
- Strategic planning support and execution oversight
- Cross-functional coordination and bottleneck removal
Engagements are typically 3–6 months minimum. Limited availability — I take on a small number of clients at a time.
Fractional Accounting Manager
I take ownership of your accounting function — not just closing the books, but building the infrastructure, insight, and team around it. You get financial clarity and the confidence to make decisions from accurate, timely data.
What I own:
- Month-end and year-end close process
- Financial reporting and management dashboards
- Accounting systems setup and optimization (QuickBooks, Sage, ERPs)
- Internal controls and process documentation
- Accounting team oversight and development
- Audit readiness and compliance support
Ideal for businesses without a full-time controller or CFO, or those in transition between finance hires.
Operational Strategy Intensive
Not ready for an ongoing engagement? Start here. A focused, structured engagement designed to surface the critical gaps, define the roadmap, and give you a clear picture of what needs to happen next — so you can move forward with confidence, whether that's with me or on your own.
Includes:
- In-depth business and operations assessment
- Financial systems and reporting review
- Gap analysis and priority map
You walk away with:
- A clear operational roadmap
- Top 3–5 highest-leverage action areas
- Honest assessment of what it will take
How an engagement works
Discovery Conversation
We talk about where your business is, where you want to go, and what's getting in the way. No sales pitch — just an honest conversation about fit.
Assessment & Scoping
I take a close look at your financial systems, operations, and team structure to identify the real leverage points — not just the surface-level symptoms.
Engagement Begins
I step in as a fractional member of your leadership team. I own my scope, I communicate clearly, and I build as I go — not just advise and leave.
Systems That Last
Every engagement ends with documented processes, a capable team, and infrastructure that runs without me. The goal is to build something that doesn't depend on my presence.
Not sure which is the right fit?
Every engagement starts with a conversation. Tell me where your business is — I'll tell you honestly what it needs and whether I'm the right person to help.
The scope of what I do — and how I do it.
I work across accounting, operations, and organizational leadership. These are the functional domains I step into as a fractional executive — not as an outside advisor, but as an owner of the outcome.
Financial Clarity & Reporting
Month-end close, management dashboards, and the financial insight that drives real decisions.
Operations & Process Design
Mapping, documenting, and rebuilding the workflows that scale with your business.
Team Development & Structure
Building the people, roles, and accountability systems to execute without bottlenecking at the top.
Strategic Pivots & Critical Transitions
Executive-level guidance when the business is at an inflection point and the stakes are high.
Where I create the most impact
Accounting Function Leadership
Owning the close process, building the team, and redesigning the accounting function for scale — QuickBooks, Sage 50, and major ERPs.
Financial Systems & Controls
Internal controls, audit readiness, compliance infrastructure, and the reporting architecture that gives leadership real visibility.
Operations Infrastructure
End-to-end process documentation, workflow automation, and the operational playbooks your team actually uses.
Revenue & Profitability Analysis
Understanding where your money actually comes from — and where it goes — to make decisions from data, not instinct.
Vendor & Project Management
Contractor and vendor relationships, project timelines, and the coordination infrastructure to deliver on commitments.
Bilingual Leadership
Fluent in English and Spanish — able to serve diverse teams, international operations, and bilingual business environments with full cultural fluency.
