Weekly Cash Forecasting That Actually Works (From My Desk)
A lightweight cash forecast routine for treasury and finance teams.
Why I forecast weekly
Monthly forecasts are too slow when cash is tight. I run a weekly forecast that focuses on reality: collections timing, payroll, rent, and large vendor payments. In today's fast-paced business environment, cash positions can change dramatically within a few days, making weekly forecasting essential for maintaining liquidity and avoiding cash flow crises.
The model I use
- Starting cash: bank balances + known settlement delays (processors, ACH, etc.). I include all available cash across all accounts, including pending deposits and uncleared checks.
- Known outflows: payroll, taxes, rent, debt service, and committed POs. I categorize these by timing and priority to understand immediate cash needs.
- Expected inflows: AR by customer with conservative collection assumptions. I analyze historical collection patterns and current customer financial health to estimate timing.
- Scenario toggle: base / cautious / worst-case. This allows me to plan for different outcomes and prepare contingency plans.
Detailed cash flow components
Operating cash flows:
- Customer collections: Based on aging reports and historical collection patterns
- Vendor payments: Scheduled payments for goods and services received
- Payroll and benefits: Salaries, wages, taxes, and benefit contributions
- Tax payments: Federal, state, and local tax obligations
- Insurance premiums: Regular premium payments and deposits
Investing cash flows:
- Capital expenditures: Equipment purchases and facility improvements
- Investment activities: Purchases or sales of investment securities
- Acquisitions: Any business or asset acquisitions
Financing cash flows:
- Debt service: Principal and interest payments on loans
- Credit facility draws: Borrowing against available credit lines
- Equity transactions: Issuance or repurchase of equity
Forecasting methodology and assumptions
I use a combination of historical analysis and forward-looking indicators:
Collection assumptions:
- Current: 95% collected within 30 days
- 30-60 days: 80% collected within 30 days
- 60-90 days: 60% collected within 30 days
- Over 90 days: 30% collected within 30 days
Payment timing:
- Net 30 terms: 70% paid on time, 30% paid within 60 days
- Net 60 terms: 80% paid on time, 20% paid within 90 days
- Immediate payments: 100% paid as scheduled
Technology and tools for cash forecasting
I leverage various tools to enhance accuracy:
- ERP integration: Direct connection to accounting systems for real-time data
- Bank feeds: Automated import of actual cash positions
- AR aging reports: Detailed customer payment history
- AP scheduling: Visibility into upcoming payment obligations
- Dashboard reporting: Visual representation of cash positions
Weekly forecasting process
Monday: Update forecast with weekend transactions and any new information Tuesday: Review with operations team for any changes in customer or vendor behavior Wednesday: Finalize forecast and share with leadership Thursday: Begin planning for next week's cash needs Friday: Document lessons learned and update assumptions as needed
Managing cash flow volatility
I prepare for various scenarios:
Conservative scenario: 20% slower collections, 10% higher expenses Base scenario: Historical patterns continue Optimistic scenario: 15% faster collections, 5% lower expenses Crisis scenario: 50% slower collections, immediate payment requirements
Communication and reporting
I create weekly reports that include:
- Current cash position vs. forecast
- Variance analysis from previous forecast
- Key assumptions and changes
- Risk factors and mitigation plans
- Action items for management review
Cash management strategies
Based on forecast results, I implement:
Short-term strategies:
- Accelerate collections through early payment discounts
- Negotiate extended payment terms with vendors
- Utilize credit facilities when needed
- Optimize cash pooling across entities
Medium-term strategies:
- Optimize working capital components
- Evaluate seasonal cash flow patterns
- Plan for major cash needs in advance
- Establish backup financing options
Risk management in cash forecasting
I identify and monitor key risk factors:
- Customer concentration risk: Over-reliance on a few customers
- Industry risk: Economic factors affecting customer payment ability
- Seasonal risk: Periodic variations in cash flows
- Operational risk: Unexpected expenses or delays
Integration with financial planning
Cash forecasting connects with broader financial planning:
- Budgeting: Monthly forecasts align with annual budget assumptions
- Strategic planning: Long-term cash needs inform strategic decisions
- Performance metrics: Cash conversion metrics tied to operational KPIs
- Risk management: Cash reserves aligned with business risk profile
Continuous improvement process
I regularly refine the forecasting process:
- Accuracy tracking: Monthly comparison of forecasts to actual results
- Assumption updates: Regular review and adjustment of collection assumptions
- Process improvements: Streamlining data collection and analysis
- Technology upgrades: Leveraging new tools and capabilities
- Training and development: Staying current with best practices
Stakeholder communication
I ensure the right people receive appropriate information:
- Executive team: High-level cash position and significant changes
- Operations: Customer and vendor payment information
- Treasury: Detailed cash positioning and financing needs
- Accounting: Support for cash-related journal entries
- Board: Cash position updates for governance purposes
