Sound familiar?

You are not bad with money.
You just do not have a system.

Most business owners we work with are smart, capable, and working hard. The problem is not effort. The problem is that the financial setup has not caught up to the business they have built.

You are making money, but still feel broke.

Revenue shows up on paper, but it does not seem to turn into actual margin. You are busy, you are billing, and you still cannot answer the question that matters most: where is the money going?

Your books are behind, so every decision feels heavier than it should.

Tax season is stressful. Your records are not where they need to be. You are not sure what you owe, what you earned, or whether the next hire, property, or project is actually affordable.

You cannot see your business clearly.

You may already have a bookkeeper or a dashboard, but the reports do not tell you what you actually need to know. You have data. You do not yet have clarity.

You want a real financial partner, not just a reconciled QuickBooks file.

You are past the point where "someone who keeps the books current" is enough. You need someone who can help you understand what the numbers are saying and what they make possible.

You are growing but your financial picture has not kept up.

Revenue is there. The business is moving. But you cannot quickly answer which part of your business is the most profitable right now, where your cash is heading over the next 90 days, or whether your growth is actually making you more money. That is not a bookkeeping problem. That is a visibility problem and a live dashboard built around your specific business fixes it.

You are building on Stripe but have not figured out the accounting layer yet.

You have a great product, a real business model, and a technical team ready to build. But the revenue recognition, journal entry framework, and GL architecture are still a whiteboard conversation. Once you go live it is much harder to fix. You need someone who understands both the engineering and the accounting before the first transaction posts, not after.

For: Billing agents, marketplaces, SaaS platforms, PropTech, and any tech-enabled startup building on modern financial infrastructure

This is not a knowledge problem. It is a systems problem.
And that is exactly what Kellcat is built to solve.

The Kellcat story

Built by an engineer.
Inspired by a CPA.

Kellcat was founded by Brian Kelly, a software engineer who has spent over 11 years building systems where precision is not a preference. It is the job.

Long before that engineering career, Brian watched his mother spend 30 years as a CPA, sitting across the table from business owners and helping them understand what their numbers were actually saying. She did not just prepare returns. She helped people see their businesses clearly.

Kellcat exists at the intersection of those two worlds. Engineering-grade precision meets real-world financial guidance. The result is a financial back office built for clarity, not complexity — designed by someone who understands both the systems and the people they serve.

Where accounting meets engineering.

How Kellcat works

We build financial systems in three layers.

Each layer depends on the one before it. Together, they move you from books that are simply correct, to numbers you can see clearly, to decisions you can make with confidence.

The numbers cannot drive decisions until they are visible.
They cannot be visible until they are right.

1

LAYER

Clean Books

The foundation. The numbers are right.

Full monthly bookkeeping close across QuickBooks, Xero, Puzzle, or your existing platform. Every account categorized, reconciled, and verified. AI-assisted plain-English summary reviewed and personalized by Brian. Monthly Loom video walkthrough. Reports on request for your CPA or lender.

Best for

Business owners who want their books handled by someone who understands the industry.

2

LAYER

Clear Picture

The visibility layer. The numbers are visible.

Everything in Clean Books, plus a custom business dashboard built specifically for your business — financial performance, cash flow, sales forecasting, and operational visibility. Built over 12 weeks in 6 structured working calls. Dashboard monitoring and updates as your business evolves.

Best for

Business owners who want a live picture of their entire business at a glance instead of digging through reports to find the answers.

3

LAYER

Confident Decisions

The strategy layer. The numbers drive decisions.

Everything in Clean Books and Clear Picture, plus a bi-weekly advisory partnership. Brian reviews your numbers with you twice a month, flags what changed, explains what it means in plain English, and helps you stay on track. Cash flow forecasting. Budget reviews. Quarterly KPI framework review. Annual business review. A dedicated Slack channel between meetings.

Best for

Business owners who want someone in their corner twice a month who can review the numbers, flag what changed, and help them decide what to do next. Requires an existing Clear Picture dashboard.

Who is Kellcat for

Real estate investors, tech founders, and growing businesses
ready for a real financial system.

Whether you need clean books, a custom dashboard, or full accounting architecture, every engagement starts with getting the numbers right.

Short-Term Rental Operators

Need to know which properties are carrying their weight after platform fees, cleaning costs, repairs, and seasonality.

House Flippers

Need project-level clarity that accounts for materials, holding costs, soft costs, and the renovation that went over budget.

Long-Term Landlords & BRRRR Investors

Need portfolio-level reporting that does not require a weekend of spreadsheet cleanup every month and lender-ready visibility before the next refinance window opens.

Small Business Owners

Bakeries, service businesses, creatives, contractors, and other owner-operators who want clean books, a live dashboard, and a financial partner who can tell them what the numbers actually mean, not just reconcile them.

Tech-Enabled Startups & Fintech Founders

Building on Stripe, Puzzle, or Mercury? Launching a billing agent model, marketplace, or SaaS platform? Kellcat designs the accounting architecture your engineering team builds to.

Growing Businesses

Revenue is coming in, but the financial systems have not kept up. You need a live dashboard and a financial partner, not just a bookkeeper. Kellcat's Clear Picture and Confident Decisions tiers are built for this stage.

If your business does not fit neatly into one category, that is fine. Book a Discovery Call and Brian will help you determine whether Kellcat is the right fit. Building on Stripe or launching a fintech platform? See how Kellcat works with tech-enabled startups →

What makes Kellcat different

Most bookkeepers reconcile your accounts.
Kellcat builds your financial system.

That difference shows up in five ways.

1

Engineering-grade precision.

Brian spent 11 years building aerospace software where one bad number mattered. That same standard sits behind every reconciliation, every category, and every monthly close.

2

AI assists. Brian approves.

Kellcat uses AI to support repetitive drafting, summaries, and pattern review. But every report, summary, and analysis that reaches you is reviewed, edited, and approved by Brian. You get efficiency without handing judgment over to software.

3

Modern tools, not just the defaults.

Kellcat works across QuickBooks, Xero, and Puzzle, an AI-native accounting platform with native Mercury and Stripe integration. We use the right tool for the job, not just the one everyone else defaults to.

Advanced QuickBooks ProAdvisor · Xero Certified Advisor · Puzzle Advisor

4

Kellcat does bookkeeping. Your CPA does taxes.

Kellcat keeps your books clean and your financial picture sharp. Your CPA handles tax filing and tax advice. Clear lanes mean cleaner handoffs and fewer year-end surprises.

5

Boundaries are part of the system.

Response times are stated in writing. Weekends are protected. That is not a lack of service. It is how Kellcat keeps the work clear, accurate, and sustainable.
