Separate timing from performance.
A margin issue needs pricing, cost, mix, or delivery action. A timing issue needs billing, collections, terms, WIP, inventory, or payment planning. Good working capital review keeps those stories separate.

Methodology, formulas, assumptions, and pressure-score thresholds
Operating working capital = estimated accounts receivable + estimated inventory/WIP - estimated accounts payable. AR uses monthly revenue ÷ 30 × collection days; inventory/WIP and payables use monthly direct cost ÷ 30 × their respective days. Cash conversion days = collection days + inventory/WIP days - payable days. Minimum cash cushion = estimated weekly cash cost × cash-coverage weeks; weekly cash cost estimates direct cost plus 45% of non-direct-cost revenue, divided by 4.33.
- Operating cycle: 0 points at 40 days or less; 1 at 41-60; 2 above 60.
- Capital intensity: 0 points at 75% or less of monthly revenue; 1 above 75%-115%; 2 above 115%.
- Direct-cost load: 0 points at 70% or less of revenue; 1 above 70%-85%; 2 above 85%.
- Cash coverage: 0 points at 5 weeks or more; 1 from 3 to under 5; 2 below 3.
Industry Pressure Map
Do not use the same working capital forecast for every business model.
The math is similar, but the assumptions and management actions are different.
| Industry | Cash gets trapped in | Forecast should watch | Best monthly question | Management follow-up |
|---|---|---|---|---|
| Construction and trades | WIP, retainage, unapproved change orders, slow progress billing | Billings ahead or behind production, retainage release dates, subcontractor payments, payroll, change-order status | Will the next jobs require more cash before existing work converts? | Assign an owner to WIP accuracy, billing milestones, and collection dates |
| Manufacturing | Raw materials, WIP, finished goods, customer receivables, purchase commitments | DIO, DSO, vendor terms, backlog, production schedule, slow-moving inventory, material cost changes | Are purchases and production building cash pressure before sales collect? | Reconcile inventory and production assumptions before committing purchases |
| Professional services | Unbilled work, retainers consumed too quickly, receivables, write-offs, payroll timing | Utilization, realization, billing cycle time, AR aging, retainer coverage, staffing commitments | Is profitable work becoming cash before payroll and hiring commitments arrive? | Validate project economics and staffing commitments before changing pricing |
| Distribution | Inventory, receivables, supplier minimums, freight, customer terms | Inventory turns, fill rate, margin by SKU or customer, DSO, DPO, purchasing commitments | Which inventory and customer terms are funding growth, and which are absorbing cash? | Review inventory commitments, supplier terms, and customer collections |
| Healthcare | Insurance receivables, denials, provider payroll, patient collections, billing lag | AR by payer, denial rate, provider productivity, payroll coverage, patient balances, cash runway | Are revenue-cycle delays or provider capacity creating the cash low point? | Validate payer timing and payroll commitments with the responsible team |
| Technology and SaaS | Annual contracts, deferred revenue, payroll, customer acquisition, implementation costs | Burn, runway, ARR quality, churn, CAC payback, hiring plan, billing terms, deferred revenue obligations | Does the runway support the next hiring, product, and sales commitments? | Reconcile recurring-revenue definitions and approved spending before planning capital |
Forecast Design
Build the forecast around decisions, not just formulas.
Name the operating owner.
Receivables, change orders, inventory, billing approvals, payer denials, and purchase commitments need owners. A forecast without ownership becomes a spreadsheet instead of a management system.
Connect the low point to action.
The forecast should explain whether to accelerate collections, delay spending, revise hiring, adjust purchasing, negotiate terms, use financing, or schedule a leadership consultation.

Financial Leak Calculator
Estimate where margin, collections, labor cost, or cash pressure may deserve investigation. It uses your inputs and does not verify the books.
Autonomous Watchtower
Monitor supported conditions in current QuickBooks evidence, with the numbers, calculation, significance, confidence, and limitations attached. It does not forecast cash or make management decisions.
Separate monitoring from professional work
TruePoint does not repair bookkeeping, approve transactions, own a forecast, or provide a dedicated finance adviser. When the source evidence is insufficient, the Watchtower must say so instead of producing a conclusion.
