Frequently Asked Questions
How far ahead should I forecast cash flow?
Minimum 13 weeks for operational needs, 12 months for planning, and 2-3 years for strategic decisions. Short-term forecasts should be more detailed and accurate than long-term projections.
What's the difference between cash flow and profit?
Profit is revenue minus expenses over a period. Cash flow tracks actual money in and out of your bank account. You can be profitable but still have cash flow problems if customers pay late or you invest heavily in inventory.
How often should I update my cash flow forecast?
Update your 13-week forecast weekly, monthly forecast every month, and annual forecast quarterly. More frequent updates improve accuracy and help you spot problems early.
What if my actual cash flow differs significantly from my forecast?
Analyze the variances to understand what went wrong. Common causes include optimistic sales projections, unexpected expenses, or changes in customer payment behavior. Use these insights to improve future forecasts.
