# Managing Cash Flow Forecasting

## When To Use

- Building or refreshing a short-term (13-week) or long-term (12–24 month) cash flow forecast
- Preparing liquidity analyses for board reporting, lender covenant compliance, or capital planning
- Performing variance analysis on prior forecast periods to improve future accuracy
- Stress-testing cash positions under downside scenarios (revenue shortfall, delayed collections, accelerated payables)
- Supporting treasury decisions on draw-downs, investments, or debt repayment timing

## Inputs To Gather

- **Historical cash flow data**: Minimum 12 months of actual bank statements or ERP cash ledger exports (operating, investing, financing categories)
- **Revenue pipeline**: Booked revenue, contracted backlog, and probabilistic pipeline by expected collection date
- **Payables schedule**: Committed expenditures, vendor payment terms, payroll calendar, tax due dates, debt service schedule
- **Working capital metrics**: Current DSO, DPO, DIO; any recent trend shifts or seasonal patterns
- **Capital expenditure plan**: Approved and pending capex with expected disbursement timing
- **Financing facilities**: Revolver availability, term loan amortization, letter-of-credit commitments, covenant thresholds (minimum liquidity, fixed charge coverage) [VERIFY specific covenant definitions per credit agreement]
- **Assumptions register**: FX rates, interest rate curves, intercompany settlement timing, dividend policy

## Workflow

1. **Define forecast horizon and granularity**
   - 13-week forecast: weekly buckets, direct-method (receipts and disbursements)
   - 12–24 month forecast: monthly buckets, indirect-method starting from EBITDA or net income
   - Confirm reporting currency and any multi-currency consolidation requirements

2. **Build the receipts model**
   - Map booked receivables to expected collection weeks using historical DSO distribution (not a single-point average)
   - Layer in probabilistic pipeline receipts with weighted probability haircuts
   - Add non-operating inflows: asset disposals, tax refunds, insurance proceeds, intercompany loans

3. **Build the disbursements model**
   - Slot committed payables by contractual due date and actual payment behavior (early-pay discounts vs. stretch)
   - Include payroll, benefits, and tax withholding on their fixed calendar dates
   - Schedule debt service (principal + interest), capex draws, and dividend payments
   - Add contingency line items for unplanned outflows (litigation reserves, warranty claims) with probability weighting

4. **Calculate net cash flow and cumulative position**
   - Net weekly/monthly cash flow = total receipts minus total disbursements
   - Cumulative cash = opening cash + net cash flow + any facility draws/repayments
   - Flag any period where projected cumulative cash falls below minimum liquidity threshold or covenant floor

5. **Run scenario and sensitivity analysis**
   - **Base case**: Management's best estimate
   - **Downside case**: Revenue delayed by X days, top-customer default, capex acceleration
   - **Upside case**: Accelerated collections, deferred discretionary spend
   - Identify the breakeven assumptions that would trigger a liquidity shortfall

6. **Perform variance analysis on prior periods**
   - Compare each line item's forecast vs. actual for the most recent 4–8 periods
   - Compute forecast accuracy metrics: Mean Absolute Percentage Error (MAPE) by line item
   - Identify systematic biases (e.g., consistently over-forecasting collections) and adjust current model inputs accordingly

7. **Document liquidity action triggers**
   - Define thresholds that trigger specific treasury actions (e.g., draw on revolver if projected cash < $X for 2+ consecutive weeks)
   - Specify escalation path: treasury analyst -> CFO -> board if minimum liquidity is breached under base case

## Output

The deliverable is a **Cash Flow Forecast Report** containing:

- **Executive summary**: Current liquidity position, forecast horizon covered, key risks and recommended actions
- **Forecast schedule**: Tabular receipts/disbursements by period with net and cumulative cash rows
- **Scenario comparison table**: Base, downside, and upside cumulative cash by period with covenant headroom noted
- **Variance analysis**: Prior-period forecast vs. actual with MAPE and bias direction per major line item
- **Assumptions register**: Every material assumption documented with source and last-validated date
- **Action trigger matrix**: Liquidity thresholds mapped to specific treasury responses and responsible parties

## Quality Checks

- Confirm opening cash balance ties to the most recent bank reconciliation or treasury report
- Verify debt service amounts match the amortization schedule in the credit agreement [VERIFY]
- Ensure covenant calculations use the same definitions as the credit agreement (e.g., whether cash includes restricted cash) [VERIFY]
- Check that FX conversion rates are sourced consistently and dated appropriately
- Validate that the sum of weekly buckets in the 13-week forecast reconciles to the corresponding monthly totals in the long-term forecast
- Confirm no double-counting of intercompany flows in consolidated forecasts
- Review that probability weights on pipeline receipts reflect current sales team assessments, not stale data
- Ensure variance analysis covers enough periods (minimum 4) to identify trends rather than one-off anomalies
