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

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.

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 — any model where a licensed professional delivers the service and your platform handles the billing.

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 and homeowners become the payer.
This is the most technically complex accounting model we work with and the one where getting it wrong creates the most downstream liability. 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 — any two-sided market where you facilitate the transaction but the seller delivers the service.

The accounting problem: Gross vs. net revenue determination, Stripe Connect seller payouts, 1099-K reporting obligations for seller payments, refund and dispute handling across multiple parties, and marketplace facilitator sales tax where applicable.
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 to handle it.

B2B SaaS platforms, vertical software companies, API-first products, usage-based billing models, seat-based licensing, consumption pricing — companies adding professional services or implementation fees to their core subscription.

The accounting problem: ASC 606 performance obligation identification and allocation, deferred revenue schedules in Puzzle, MRR vs. GAAP revenue reconciliation, Stripe Billing integration without duplicating entries, and contract modification accounting when customers upgrade or downgrade.
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, vacation rental operators with platform infrastructure — real estate transaction platforms with embedded payments or escrow features.

The accounting problem: Trust accounting for security deposits, owner disbursement agent model identical to billing agent treatment, 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 — any professional services firm with milestone-based project billing or retainer structures.

The accounting problem: Work in progress tracking, milestone-based revenue recognition timing, retainer deferred revenue treatment, contractor vs. employee classification impact on the books, 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 — insurance claim management platforms, TPA technology, and managed repair networks.

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.
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.
