You can explain your system architecture.
Can your accountant follow along?

Most accountants cannot. Your CPA understands revenue recognition in theory. Your engineering team can build anything. But neither of them has designed a journal entry framework for a Stripe Connect billing agent model, mapped a deferred revenue schedule to a usage-based billing engine, or told your dev team exactly what data to push to Puzzle and when.

Kellcat sits in that gap. With eleven years of software engineering experience and a second-generation accounting background rooted in a CPA firm, we speak both languages natively. We design the accounting infrastructure your technical team builds to and we set it up in Puzzle so it works from the first transaction.

The Difference
Most bookkeepers learn your accounting after your business is built. Kellcat designs your accounting architecture before your first line of code is written.

This page is for you if…

  • You are the kind of founder who would rather talk about webhook event triggers than basic bookkeeping and you need an accountant who gets that
  • Your business model involves money moving through your platform on behalf of others such as providers, sellers, contractors, or partners
  • Your revenue recognition is more complex than invoice sent, payment received, done
  • Your engineering team is building before the accounting architecture is decided
  • You need a chart of accounts and journal entry framework that reflects how your platform actually works, not a generic QuickBooks template
  • You are building on Stripe, Puzzle, or Mercury and need the accounting layer to match
  • You want an advisor who can sit in a technical architecture review and tell you which events need separate GL treatment
  • You need it designed right the first time, not rebuilt after your CPA flags it at year-end or your auditor asks questions

This page is for you if…

If any of these sound familiar, your accounting infrastructure needs to be designed — not defaulted.

  • You think in systems, not spreadsheets You would rather talk webhook event triggers than basic bookkeeping and you need an accountant who gets that.
  • Money moves through your platform on behalf of others Providers, sellers, contractors, or partners — and that pass-through needs to be accounted for correctly.
  • Your revenue recognition is not simple It is not just invoice sent, payment received, done. There are deferrals, milestones, or usage components involved.
  • Your engineers are building before accounting is decided The GL architecture needs to be designed now, not reverse-engineered after the product ships.
  • You need a chart of accounts that reflects your actual platform Not a generic QuickBooks template someone adapted from a retail business.
  • You are building on Stripe, Puzzle, or Mercury And you need the accounting layer to match how money actually moves through those systems.
  • You want an advisor who can sit in a technical architecture review Someone who can tell you which events need separate GL treatment before your CPA sees it at year-end.
  • You need it designed right the first time Not rebuilt after your auditor asks questions you cannot answer.
Who We Work With

Six distinct patterns. One common problem.

Every company below has a different business model and a different industry. But they all share the same gap: the accounting infrastructure has not been designed to match how the platform actually works. Standard bookkeepers cannot help here. This is where Kellcat operates.

01

Billing Agents & Provider Networks

You invoice customers on behalf of licensed independent providers. You collect the full invoice amount but only your platform fee is your revenue. The provider portion is a pass-through liability — not your revenue, not your cost of goods.

Environmental testing networks, home inspection platforms, healthcare billing agents, insurance restoration networks, remediation platforms, professional services networks.

The accounting problem: ASC 606 agent vs. principal determination, net revenue recognition, provider payable treatment, Stripe Connect split payments, pro-rata short-pay waterfall calculation, and multi-payer scenarios when carriers deny claims.
This is the most technically complex accounting model we work with. If this is your model, this is exactly what Kellcat is built for.
02

Marketplace Platforms

You connect buyers and sellers and take a fee. Your gross transaction volume is not your revenue. Your take rate is. But if your books show gross revenue you are overstating income, overpaying taxes, and misleading any investor who reads your financials.

Home services marketplaces, freelancer platforms, B2B procurement networks, rental platforms, equipment sharing marketplaces, professional services directories.

The accounting problem: Gross vs. net revenue determination, Stripe Connect seller payouts, 1099-K reporting obligations, refund and dispute handling across multiple parties, and marketplace facilitator sales tax.
03

SaaS & Subscription Businesses

You started with clean monthly subscriptions. Then came annual contracts, usage-based pricing, professional services add-ons, and free trials converting to paid. Your revenue recognition went from simple to complex without anyone designing the accounting infrastructure.

B2B SaaS platforms, vertical software companies, API-first products, usage-based billing models, seat-based licensing, consumption pricing.

The accounting problem: ASC 606 performance obligation identification, deferred revenue schedules in Puzzle, MRR vs. GAAP revenue reconciliation, Stripe Billing integration without duplicating entries, and contract modification accounting.
04

PropTech & Real Estate Tech Platforms

You collect rent, manage owner disbursements, or facilitate property transactions through your platform. Tenant security deposits cannot commingle with your operating funds. Owner payouts need to be tracked separately from your revenue. Your books need to reflect the legal and operational reality of how your platform handles money.

Rent collection and owner disbursement platforms, property management software, short-term rental management platforms, real estate transaction platforms with embedded payments.

The accounting problem: Trust accounting for security deposits, owner disbursement agent model, Stripe Connect for owner payouts, property-level P&L reporting, and security deposit liability tracking separate from operating funds.
05

Professional Services Firms on Modern Infrastructure

You are a consulting firm, law firm, staffing agency, or fractional executive network that has moved to modern billing and payroll platforms. Your revenue recognition involves milestones, retainers, and work in progress. Your current bookkeeper treats every invoice like a simple cash transaction.

Boutique consulting firms, legal practices, engineering and architecture firms, staffing and talent agencies, fractional executive networks, advisory firms.

The accounting problem: Work in progress tracking, milestone-based revenue recognition timing, retainer deferred revenue treatment, contractor vs. employee classification impact, and Gusto or Rippling payroll integration with the GL.
06

HealthTech & InsurTech Billing Platforms

You coordinate healthcare or insurance-adjacent services through licensed independent providers and handle billing on their behalf. Your platform fee is embedded in the transaction. The patient or homeowner never sees a separate line item for your service. Your accounting needs to reflect agent treatment correctly or you are misstating revenue.

Physical therapy, behavioral health, dental, and home health practice management platforms, environmental testing, home inspection, and remediation networks for insurance claims.

The accounting problem: Identical to the billing agent model — ASC 606 agent treatment, provider payable, net revenue recognition, insurance carrier payment timing, partial payment pro-rata allocation, and patient or homeowner balance billing when carriers short-pay or deny.
Who We Work With

Six distinct patterns. One common problem.

Different industries, different models but the same gap. The accounting infrastructure was never designed to match how the platform actually works. Standard bookkeepers cannot help here. This is where Kellcat operates.

01

Billing Agents & Provider Networks

You built a platform that invoices on behalf of licensed providers. You know the money flowing through is not all yours. But the books treat it like it is and that liability grows every month it goes unaddressed.

The full invoice hits Stripe. The provider portion needs to clear as a payable. The platform fee is the only revenue line that belongs to the business. When that distinction is not built into the GL from day one, every financial statement produced is wrong and every investor, auditor, or acquirer who looks at the books will find it.

Environmental testing networks, home inspection platforms, healthcare billing agents, insurance restoration networks, remediation platforms, professional services networks.

Where Kellcat comes in: The ASC 606 agent vs. principal determination gets designed first. Then the provider payable framework, Stripe Connect split payment accounting, and the multi-payer waterfall for when carriers deny and homeowners become the secondary payer. This is not something that gets patched later. It has to be right from the first transaction.
This is the most technically complex model Kellcat works with. If this is your platform, this is exactly the conversation worth having.
02

Marketplace Platforms

Your GMV looks impressive. Your take rate is what actually matters. If the books are reporting gross transaction volume as revenue, income is overstated, taxes are overpaid, and any serious investor has an immediate red flag.

The gross amount hits Stripe. The seller payout goes out through Connect. The platform fee is what remains. That distinction needs to be designed into the chart of accounts and journal entry framework before volume scales because restating financials after the fact means correcting numbers already shown to people who matter.

Home services marketplaces, freelancer platforms, B2B procurement networks, rental platforms, equipment sharing marketplaces, professional services directories.

Where Kellcat comes in: Gross vs. net revenue determination, Stripe Connect seller payout accounting, 1099-K reporting obligations, refund and dispute handling across multiple parties, and marketplace facilitator sales tax treatment. The accounting layer needs to match the platform architecture. Kellcat builds it that way from the start.
03

SaaS & Subscription Businesses

The Stripe dashboard shows one number. The books show another. The CPA is asking about deferred revenue schedules that do not exist yet. This gap does not close on its own.

It started with clean monthly subscriptions. Then came annual contracts, usage-based tiers, implementation fees, and free trials converting to paid. Each layer added revenue recognition complexity the original chart of accounts was never designed to handle. The accounting infrastructure does not get redesigned automatically when the pricing model evolves. That is the gap.

B2B SaaS platforms, vertical software companies, API-first products, usage-based billing models, seat-based licensing, consumption pricing.

Where Kellcat comes in: ASC 606 performance obligation identification and allocation, deferred revenue schedules built in Puzzle, MRR to GAAP revenue reconciliation, Stripe Billing integration without duplicating entries, and journal entry logic for upgrades, downgrades, and contract modifications. The books should tell the same story the product does.
04

PropTech & Real Estate Tech Platforms

Tenant deposits, owner disbursements, and platform revenue are all moving through the same infrastructure. The legal and accounting treatment for each one is completely different. Commingling any of them is a problem that does not stay quiet.

Property money is not platform money. Security deposits are a liability until the lease ends. Owner disbursements are pass-throughs that require agent treatment identical to a billing network. Platform revenue is the only line that belongs on the income statement. When those three are not clearly separated in the GL, the financials are not just inaccurate. They may create legal exposure depending on state requirements.

Rent collection and owner disbursement platforms, property management software, short-term rental management platforms, vacation rental operators with platform infrastructure.

Where Kellcat comes in: Trust accounting for security deposits, owner disbursement agent model, Stripe Connect configuration for owner payouts, property-level P&L reporting, and deposit liability tracking completely separated from operating funds. The architecture reflects the legal reality of how the platform handles money.
05

Professional Services Firms on Modern Infrastructure

The billing and payroll platforms are modern. The accounting layer underneath them is not. Every invoice is still being treated like a simple cash transaction and that is not how this business actually works.

Milestone billing, retainers, work in progress, contractor payroll through Gusto or Rippling. Each has a distinct accounting treatment a generic setup cannot handle correctly. The result is revenue recognized at the wrong time, WIP that never hits the books, and a GL that does not reflect how the firm actually operates. The CPA sees it at year-end. Investors see it when monthly financials do not hold up to scrutiny.

Boutique consulting firms, legal practices, engineering and architecture firms, staffing and talent agencies, fractional executive networks, advisory firms.

Where Kellcat comes in: WIP tracking, milestone-based revenue recognition timing, retainer deferred revenue treatment, contractor vs. employee classification impact on the GL, and Gusto or Rippling payroll integration into the chart of accounts. The books should reflect how the firm actually delivers work, not how a generic template assumes it does.
06

HealthTech & InsurTech Billing Platforms

The platform fee is embedded in the transaction and invisible to the patient. The carrier pays. The platform takes its fee. The provider gets the rest. If the books record the full carrier payment as revenue, income is being misstated in a space that cannot afford that kind of error.

The accounting treatment follows the same agent model as any billing network such as ASC 606 agent determination, net revenue recognition, provider payable but the stakes are higher. Regulatory scrutiny is real. Partial payments, short-pays, and balance billing scenarios each require distinct journal entry logic at the transaction level. Generic bookkeeping does not have a framework for any of it.

Physical therapy, behavioral health, dental, and home health practice management platforms, environmental testing, home inspection, remediation networks for insurance claims, TPA technology, managed repair networks.

Where Kellcat comes in: ASC 606 agent treatment, provider payable framework, net revenue recognition, insurance carrier payment timing, partial payment pro-rata allocation, and journal entry logic for balance billing when carriers short-pay or deny. Every transaction type gets its own accounting treatment. The system gets designed to handle all of them cleanly.
How It Works

Four phases. No hourly billing. No surprises.

Every engagement follows the same structured path.

Phase 1 — Flat Fee
Accounting Architecture & GL Setup
Revenue recognition framework
We sit with your business model and confirm the right accounting treatment such as net vs. gross, agent vs. principal, point-in-time vs. over-time. We flag what needs your CPA to opine on before go-live. We do not replace your CPA on technical accounting opinions. We design the system that implements them.
Chart of accounts
Built specifically for your platform, not a generic template. Stripe clearing accounts, provider payables, deferred revenue, transit accounts, and platform fee revenue designed around how your money actually moves.
Journal entry framework
Every payment scenario mapped to exact journal entries. Account names, debit and credit amounts, and the specific system event that triggers each entry. Written in a format your engineering team can build to directly.
Puzzle setup
Chart of accounts configured in Puzzle. API integration architecture documented so your engineering team knows exactly what data to push, in what format, and on which event trigger. Native Stripe sync configured or disabled based on your architecture.
Mercury integration
Dedicated Mercury account setup and Puzzle bank sync configuration. Mercury webhook documentation for deposit confirmation so your GL closes automatically on every settled transaction.
Dev team build spec
A complete Puzzle or Mercury API reference with full JSON payload examples for every payment scenario your platform handles. Your engineers build to a written specification, not a whiteboard conversation that gets lost after the meeting.
Layer 1 — Monthly
Clean Books — Ongoing Bookkeeping & Reconciliation
Monthly reconciliation
All Stripe, Mercury, and Puzzle accounts reconciled monthly. Every payment scenario handled — full pay, short-pay, recovery, refunds, chargebacks, and disputes. Nothing falls through.
Financial statements
Investor-ready P&L, balance sheet, and cash flow from Puzzle. Net revenue only. Gross transaction volume tracked separately as a supplemental operational metric.
Deferred revenue tracking
Monthly deferred revenue roll-forward for SaaS and subscription businesses. Recognized vs. unearned revenue clearly separated every month.
CPA coordination
Clean books and organized documentation at year-end. Your CPA gets what they need without spending billable hours digging through raw Stripe exports.
System maintenance
Journal entry framework and chart of accounts updated as your platform evolves. New payment scenarios documented and configured as they emerge — before they create reconciliation problems.
Layer 2 — One-Time Build & Monthly Maintenance
Clear Picture — Custom Financial Dashboard
Fintech metrics dashboard
A live Klipfolio dashboard built around your platform's actual metrics — net revenue vs. gross transaction volume, platform fee revenue, provider payable aging, and MRR vs. GAAP revenue. Not a generic template.
Deferred revenue visibility
Live deferred revenue balance and monthly roll-forward visible at a glance. Recognized vs. unearned revenue tracked automatically so you always know your true financial position.
Automated data feeds
Dashboard connects directly to Puzzle, Stripe, and Mercury. Numbers update automatically — no manual exports, no spreadsheet maintenance, no stale data.
Investor-ready layout
Built to answer the questions investors and lenders ask — growth rate, net revenue trend, cash position, and platform fee contribution. Your numbers in a format that builds confidence.
Dashboard maintenance
As your platform evolves, your dashboard evolves with it. New metrics added, data feeds updated, and layout refined as your business grows. Your Clear Picture stays current — not a snapshot that goes stale six months after delivery.
Layer 3 — Monthly
Confident Decisions — Business Advisory
Bi-weekly advisory sessions
Scheduled calls with Brian every two weeks. Live dashboard review, GL health check, and a focused conversation on what your numbers are telling you. No prep needed — everything is already in the dashboard.
GL health monitoring
Every session starts with a review of the books. Reconciliation gaps, unusual entries, and system anomalies caught and resolved before they compound. Your GL stays clean between closes.
Cash runway and burn rate
Monthly cash runway calculation and burn rate tracking built into every advisory session. Know exactly how long your current cash position lasts at current spend — before your investors ask.
Scenario forecasting
Forward-looking financial models built around your actual revenue architecture — not generic spreadsheet templates. Model the impact of new pricing tiers, platform fee changes, or growth scenarios on your net revenue and runway.
System evolution support
As your platform adds payment scenarios, pricing models, or new integrations, your accounting architecture evolves with it. New flows documented and configured before they hit the books.
CPA and investor prep
Year-end ready books, clean audit trail, and organized documentation. Whether you are heading into a funding round, a tax filing, or an investor review, your financials are never a last-minute scramble.
How It Works

Four phases. No hourly billing. No surprises.

Every engagement follows the same structured path from architecture design on day one to ongoing books, dashboards, and advisory as the platform grows.

Phase 1 — Flat Fee
Accounting Architecture & GL Setup

Before a single transaction posts, the accounting infrastructure gets designed. Chart of accounts, journal entry framework, Puzzle configuration, and a build spec your engineering team can work from directly.

Revenue recognition framework
The business model gets mapped to the correct accounting treatment such as net vs. gross, agent vs. principal, point-in-time vs. over-time. What needs a CPA opinion gets flagged before go-live. The system gets designed to implement those decisions correctly from the first transaction.
Chart of accounts
Built specifically for the platform, not a generic template adapted from a retail business. Stripe clearing accounts, provider payables, deferred revenue, transit accounts, and platform fee revenue structured around how money actually moves through the system.
Journal entry framework
Every payment scenario mapped to exact journal entries with account names, debit and credit amounts, and the specific system event that triggers each entry. Written in a format the engineering team can build to directly, not a whiteboard conversation that gets lost after the meeting.
Puzzle setup
Chart of accounts configured in Puzzle. API integration architecture documented so the engineering team knows exactly what data to push, in what format, and on which event trigger. Native Stripe sync configured or disabled based on the platform architecture.
Mercury integration
Dedicated Mercury account setup and Puzzle bank sync configuration. Mercury webhook documentation for deposit confirmation so the GL closes automatically on every settled transaction.
Dev team build spec
A complete Puzzle or Mercury API reference with full JSON payload examples for every payment scenario the platform handles. Engineers build to a written specification — not assumptions made during a call that no one documented.
Layer 1 — Monthly
Clean Books — Ongoing Bookkeeping & Reconciliation

Every Stripe, Mercury, and Puzzle account reconciled monthly. Every payment scenario covered. Investor-ready financials produced without a last-minute scramble at year-end.

Monthly reconciliation
All Stripe, Mercury, and Puzzle accounts reconciled every month. Full pay, short-pay, recovery, refunds, chargebacks, and disputes. Every scenario handled. Nothing falls through because the journal entry framework was designed to cover all of them.
Financial statements
Investor-ready P&L, balance sheet, and cash flow from Puzzle. Net revenue only. Gross transaction volume tracked separately as a supplemental operational metric because conflating the two is exactly the kind of error that raises questions in a funding round.
Deferred revenue tracking
Monthly deferred revenue roll-forward for SaaS and subscription businesses. Recognized vs. unearned revenue clearly separated every month so the books always reflect the true financial position, not just cash collected.
CPA coordination
Clean books and organized documentation delivered at year-end. The CPA gets what they need without spending billable hours sorting through raw Stripe exports or reconstructing a reconciliation that should have been done monthly.
System maintenance
Journal entry framework and chart of accounts updated as the platform evolves. New payment scenarios documented and configured as they emerge before they create reconciliation problems that take three months to unwind.
Layer 2 — One-Time Build & Monthly Maintenance
Clear Picture — Custom Business Dashboard

A live dashboard built around the platform's actual metrics, not a generic template someone configured in an afternoon. Net revenue, deferred revenue, MRR vs. GAAP, and cash position in one place, updated automatically.

Fintech metrics dashboard
Built in business dashboard around the platform's actual metrics like net revenue vs. gross transaction volume, platform fee revenue, provider payable aging, and MRR vs. GAAP revenue. Every number that matters to a founder or investor, visible at a glance.
Deferred revenue visibility
Live deferred revenue balance and monthly roll-forward visible without opening a spreadsheet. Recognized vs. unearned revenue tracked automatically so the true financial position is always clear — not reconstructed at quarter-end.
Automated data feeds
Dashboard connects directly to Puzzle, Stripe, and Mercury. Numbers update automatically, no manual exports, no spreadsheet maintenance, no stale data being used to make current decisions.
Investor-ready layout
Built to answer the questions investors and lenders ask such as growth rate, net revenue trend, cash position, and platform fee contribution. The numbers in a format that builds confidence before the conversation starts.
Dashboard maintenance
As the platform evolves, the dashboard evolves with it. New metrics added, data feeds updated, layout refined as the business grows. Not a snapshot that goes stale six months after delivery.
Layer 3 — Monthly
Confident Decisions — Business Advisory

Bi-weekly sessions with someone who has already reviewed the books and knows what the dashboard is showing. No prep required. The numbers are already there. The conversation is about what they mean and what to do next.

Bi-weekly advisory sessions
Scheduled calls every two weeks. Live dashboard review, GL health check, and a focused conversation on what the numbers are telling you. Everything is already in the dashboard where no prep is needed on either side.
GL health monitoring
Every session starts with a review of the books. Reconciliation gaps, unusual entries, and system anomalies caught and resolved before they compound. The GL stays clean between closes, not just on the day the CPA asks for it.
Cash runway and burn rate
Monthly cash runway calculation and burn rate tracking built into every advisory session. Know exactly how long the current cash position lasts at current spend before investors ask, not after.
Scenario forecasting
Forward-looking financial models built around the actual revenue architecture, not generic spreadsheet templates. Model the impact of new pricing tiers, platform fee changes, or growth scenarios on net revenue and runway before committing to a direction.
System evolution support
As the platform adds payment scenarios, pricing models, or new integrations, the accounting architecture evolves with it. New flows documented and configured before they hit the books, not discovered during a reconciliation three months later.
CPA and investor prep
Year-end ready books, clean audit trail, and organized documentation. Whether heading into a funding round, a tax filing, or an investor review, the financials are never a last-minute scramble because the work has already been done every month.

Pricing

Transparent pricing. No hourly billing.

Every engagement is scoped before any work begins. The complexity of the platform, number of payment scenarios, and systems involved all affect the scope which is why pricing is confirmed after a free discovery call, not listed on a rate card.

Phase 1 — Flat Fee
Accounting Architecture & GL Setup

The foundation everything else depends on. Scoped and priced after discovery because no two platforms move money the same way.

Scope is confirmed after the discovery call. The number of payment scenarios, platforms involved, and complexity of the business model all affect what this engagement covers. Everything is agreed in writing before any work begins. No surprises or no scope creep.
Layer 1 — Monthly
Clean Books — Ongoing Bookkeeping & Reconciliation

Priced after Phase 1 is complete and the live system has been reviewed. Transaction volume and complexity determine the rate — not an arbitrary monthly fee.

The monthly rate is confirmed before the ongoing engagement begins. Every Stripe, Mercury, and Puzzle account covered. Every payment scenario handled. The number you agree to is the number on the invoice every month.
Layer 2 — One-Time Build & Monthly Maintenance
Clear Picture — Custom Business Dashboard

A one-time build scoped after discovery, plus a monthly maintenance rate so the dashboard stays current as the platform evolves.

Built around the platform's actual metrics for business such as net revenue, deferred revenue, provider payable aging, and MRR vs. GAAP revenue. Scope and both pricing components confirmed before the build begins. No generic templates delivered and left to go stale.
Layer 3 — Monthly
Confident Decisions — Bi-Weekly Advisory

Scoped after Layer 1 is established. Advisory built on a foundation of clean books, not guesswork and spreadsheets pulled together before the call.

Includes bi-weekly advisory sessions, GL health monitoring, cash runway and burn rate tracking, scenario forecasting, and CPA and investor prep. Everything forward-looking is grounded in numbers that are already reconciled and current.
No hourly billing. No surprise invoices.
Scope and price agreed before any work begins.
The discovery call is free. If the engagement is not the right fit, that gets said plainly before either side commits to anything.
