Finance Operating Systems Collection

The best-value option for finance leaders who want the complete StackedCFO workflow library instead of buying one system at a time.

Revenue & Cost Systems

Start with margin quality, revenue quality, and the economics behind growth.

These are the systems for teams that need bookings, billings, ARR, COGS, inventory, cost behavior, and product profitability to tie into one management view.

Revenue & Cost Bundle product thumbnail

Revenue & Cost Bundle

Paired Bundle · $297

Connect revenue quality to true product margin.

Pairs RevOps OS and Cost Accounting OS so finance teams can manage bookings, billings, ARR, churn, revenue recognition, cash conversion, COGS, inventory, product profitability, reserves, and margin quality together.

$297RevOps OS · Cost Accounting OS

Built for: CFOs, controllers, SaaS finance teams, product companies, PE-backed operators, and finance teams managing revenue quality and margin.

  • RevOps OS for bookings, ARR/MRR, NRR, ASC 606, churn, cohorts, billing, collections, and cash conversion
  • Cost Accounting OS for inventory, COGS, variance analysis, product profitability, reserves, and COGS vs OpEx classification
  • Built for teams that need to explain both top-line durability and margin integrity

Why it matters

Revenue growth without cost clarity can hide the exact margin problem the board or buyer will notice first.

RevOps OS product thumbnail

RevOps OS

Standalone · $197

Connect bookings, billings, revenue recognition, and cash.

A browser-based revenue operations system for managing the full revenue lifecycle: bookings, billings, collections, ARR/MRR, NRR, ASC 606 revenue recognition, churn, cohorts, cash conversion, and contract risk flags.

$197Revenue Operations System

Built for: RevOps leaders, CFOs, controllers, revenue accounting teams, SaaS finance, and subscription businesses.

  • Revenue dashboard, bookings management, billings and collections, ARR/MRR analytics, ASC 606 workflow, churn/cohort analysis, and cash conversion
  • Helps reconcile the revenue story across sales, finance, accounting, and collections
  • Includes operator guide, secret sauce manual, AI prompt library, reference cards, and setup instructions

Why it matters

The three ARR numbers that never tie are not a formatting problem. They are a revenue quality problem.

Cost Accounting OS product thumbnail

Cost Accounting OS

Standalone · $197

See true product cost before margin becomes a surprise.

A browser-based cost accounting system for inventory, COGS, manufacturing variances, product profitability, inventory reserves, COGS vs OpEx classification, and cost-accounting issue detection.

$197Cost Structure · Inventory · Margin System

Built for: Controllers, cost accountants, manufacturing finance, CFOs, product companies, and PE-backed operators.

  • Cost Structure Map, Inventory Ledger, COGS Builder, Variance Engine, Product Profitability, Inventory Reserve, COGS vs OpEx Classifier, and Faux Pas Audit
  • Built for SaaS, manufacturing, product, distribution, and PE portfolio environments where margin quality matters
  • Includes operator guide, secret sauce manual, AI prompts, quick reference PDF, and setup instructions

Why it matters

Reported gross margin can look clean while reserves, overhead, standard cost, and classification errors accumulate underneath.

Controller Systems

Choose the full controllership platform or only the component you need.

AI Controller OS combines close management and AR/AP automation. The two components are also available separately for buyers who only need close acceleration or working capital operations.

AI Controller OS product thumbnail

AI Controller OS

2 Systems · $297

Build a controllership function that closes faster and controls working capital.

Combines Close Acceleration OS and AR/AP Automation OS into one controllership platform for month-end close, journal entries, reconciliations, accruals, flux analysis, collections, payables, vendors, and working capital visibility.

$297Close Acceleration OS · AR/AP Automation OS

Built for: Controllers, accounting managers, CFOs, shared services, and PE-backed finance teams.

  • 5-phase close workflow, 35-task close checklist, JE review log, reconciliation tracker, accrual review, and flux analysis
  • AR aging, DSO, collection workflow, AP three-way match, vendor master, and working capital dashboard
  • Designed to reduce tribal knowledge and create repeatable accounting operations

Why it matters

The close often breaks where the checklist ends: undocumented judgment, recurring exceptions, and work living in one person’s head.

Close Acceleration OS product thumbnail

Close Acceleration OS

Standalone · $197

The close that survives the person who runs it.

A standalone close operating system for teams that want the close workflow without the full AI Controller OS bundle. Use it to standardize ownership, due dates, JE review, reconciliations, accruals, flux analysis, and close completion tracking.

$197Financial Close System

Built for: Controllers, assistant controllers, accounting managers, and corporate accounting teams.

  • 5-phase, 35-task close checklist with owner, due date, status, and live completion percentage
  • JE review log with flag system and status filter
  • Reconciliation tracker, accrual review, and flux analysis with threshold flagging

Why it matters

The most expensive close risk is not software. It is undocumented process knowledge that walks out the door.

AR/AP Automation OS product thumbnail

AR/AP Automation OS

Standalone · $197

Make receivables, payables, and working capital visible in one place.

A standalone operational accounting system for teams that want the AR/AP component without buying the combined AI Controller OS. Built for invoice aging, collection follow-up, payables matching, vendor analytics, and working capital KPIs.

$197Receivables · Payables · Working Capital

Built for: Controllers, AP/AR managers, finance operations teams, and CFOs improving working capital.

  • AP invoice workflow with three-way match and exception flagging
  • Vendor master, concentration analysis, and working capital dashboard for DSO, DPO, DIO, and CCC

Why it matters

Working capital discipline starts with invoice-level visibility, not a month-end summary.

Technical Accounting

For accounting positions that need to be researched, documented, and defended.

Technical Accounting OS combines the core memo workflow with Revenue Ops & Deal Contracts support, making it the accounting-policy layer of the broader StackedCFO library.

Why it matters

A strong memo documents the reasoning before the conclusion looks inevitable.

Other Individual Systems

Focused systems for planning, reporting, diligence, tax, treasury, and advisory practice management.

Use these when you want one targeted operating system rather than the full collection.

Why it matters

Why it matters

Buyers reject patterns, weak support, and credibility gaps long before they reject the math.

AI Corporate Tax OS product thumbnail

Build tax positions that are organized before anyone asks.

A corporate tax operations system for entity setup, multi-state nexus, book-to-tax adjustments, M-1 reconciliation, state apportionment, estimated payments, compliance calendar, R&D credit, Section 174, deal structure comparison, notices, tax positions, and ETR bridge.

  • State apportionment, estimated payments, compliance calendar, R&D credit with Section 174 impact, and asset vs stock comparison
  • IRS notice tracker, tax position inventory, and ETR bridge

Why it matters

A perfectly clean M-1 can be less believable than a supported one.

AI Treasury OS product thumbnail

Make liquidity an answer, not a scramble.

A treasury operating system for multi-entity cash, currency consolidation, 13-week liquidity forecasting, FX exposure, P&L sensitivity, hedge ratios, hedging ladder, derivative valuation, hedge accounting JEs, board treasury reporting, and covenant compliance.

  • 13-week consolidated liquidity forecast with threshold alerts
  • FX exposure mapping, hedge ratios, tenor ladder, shock scenarios, derivative valuation, hedge accounting journal entries, board treasury report, and covenant table

Why it matters

A deteriorating hedge ratio can tell lenders more than a covenant package.

AI Fractional CFO OS product thumbnail

Run the advisory practice with the discipline you sell to clients.

A practice operating system for fractional CFOs managing client portfolios, retainers, health scores, deliverables, meetings, per-client finance command centers, AI deliverables, capacity, practice P&L, revenue concentration, playbooks, service tiers, positioning, and pipeline.

Delivery & Use

Built for immediate use, not enterprise procurement.

Each purchase is a digital download through Gumroad. Systems are designed for local use and practical customization.

One-time purchase

No subscription requirement. Download the product, keep the files, and use them as internal operating tools.

Workflow-first

Each system is organized around the work finance teams actually perform: ownership, review, exception handling, documentation, reporting, and decision support.

Professional review still matters

These are drafting, analysis, workflow, and reporting tools. They do not replace licensed tax, audit, legal, valuation, or accounting judgment.

AI note: Where AI-assisted prompts or narrative modules are included, they are optional drafting aids. Final conclusions, filings, accounting positions, tax positions, and management representations remain the responsibility of qualified professionals.
