Standard Operating Procedure

Registry ID: TR-12-MONTH

1. System Overview & Purpose

Purpose: A dynamic 12-month rolling cash flow forecast designed to monitor liquidity, burn rate, and runway. It serves as the primary tool for treasury management and capital allocation decisions. Scope: Captures operational, investing, and financing cash flows. Update Cadence: Monthly (actuals reconciliation) and rolling forecast adjustment.

2. Data Structure & Column Definitions

Field Name	Data Type	Validation / Logic
Category	Text	Dropdown: [Revenue, COGS, OpEx, Capex, Financing]
Sub-Category	Text	Description (e.g., Subscription, Salaries, SaaS)
Date	Date	MM/DD/YYYY (First of month)
Amount	Currency	Numeric
Status	Text	Dropdown: [Actual, Forecast]
Confidence	Percentage	100% (Actual), 50-90% (Forecast)

3. Master Data Table (Sample)

Category	Sub-Category	Date	Amount	Status	Confidence
Revenue	Subscriptions	2024-01-01	50000	Actual	100%
COGS	Hosting Fees	2024-01-01	-5000	Actual	100%
OpEx	Salaries	2024-02-01	-25000	Forecast	90%
OpEx	Marketing	2024-02-01	-8000	Forecast	70%
Capex	Equipment	2024-03-01	-12000	Forecast	50%
Financing	Loan Repayment	2024-03-01	-2000	Forecast	100%
Revenue	Services	2024-04-01	15000	Forecast	60%
OpEx	Rent	2024-04-01	-4000	Forecast	100%

4. Key Formulas & Calculation Logic

Monthly Net Cash Flow: =SUMIFS(Amount_Range, Date_Range, [Target_Month], Category_Range, "<>Financing")
Ending Cash Balance: =Opening_Balance + Current_Month_Net_Cash_Flow
Weighted Forecast Amount (Risk-Adjusted): =Amount * Confidence_Percentage
Runway Calculation: =Cash_on_Hand / ABS(AVERAGEIF(Net_Cash_Flow_Range, "<0"))

5. Summary KPI Dashboard

Designed for the "Executive Summary" tab using SUMIFS and OFFSET functions:

KPI	Logic/Formula
Total Inflow	`=SUMIFS(Amount, Status, "Actual", Amount, ">0")`
Total Outflow	`=SUMIFS(Amount, Status, "Actual", Amount, "<0")`
Burn Rate (Monthly)	`=AVERAGEIFS(Amount, Category, "OpEx", Status, "Actual")`
Forecasted Net	`=SUMIFS(Amount, Status, "Forecast")`

6. Standard Operating Workflow

Reconciliation (Day 1-3 of month): Export "Actuals" from accounting software (Xero/QBO) and paste into the Master Data table. Set Status to "Actual".
Forecast Refresh (Day 4-5): Update the Amount for future months based on the latest pipeline data. Adjust Confidence levels based on lead probability.
Variance Analysis: Compare "Forecast" (from the previous month's sheet) vs. "Actuals". If variance > 10%, audit the underlying category.
Sensitivity Adjustments: Stress-test the 12-month outlook by applying a 0.8x multiplier to "Revenue" categories to model worst-case scenarios.
Review: Validate the Runway KPI; if < 6 months, trigger capital raise or cost-cutting protocols.
