Burkland Brief:

  • Use two lenses. 13-week forecast for liquidity, 12-month forecast for strategy.
  • Keep it fresh. Update weekly and monthly.
  • Share often. Align leadership, lenders, and partners.
  • Spot trends. Short-term dips can reveal long-term issues.
  • Cross-check. Ground long-term assumptions in short-term data.

When it comes to cash forecasting, too many businesses make the mistake of choosing between short-term and long-term models. In reality, you need both. A 13-week cash flow forecast and a 12-month rolling forecast serve different purposes, and together they give you a clear view for making confident financial decisions.

If you’re only looking 13 weeks ahead, you’re flying blind beyond the next quarter. You may miss long-term cash shortages tied to seasonality, expansion costs, or debt refinancing that won’t show up until six or nine months from now. By the time those issues surface, your options are limited. You can’t easily raise capital, cut expenses, or restructure debt overnight. On the other hand, if you only forecast 12 months ahead, you risk overlooking the day-to-day realities like a payroll crunch three weeks from now or a vendor payment that drains liquidity faster than expected.

Together, these two views create a dynamic system: short-term clarity for execution, long-term perspective for strategy.

The 13-Week Cash Flow Forecast: Daily Discipline

A 13-week forecast zeroes in on liquidity. It maps inflows and outflows week by week over the next quarter, showing exactly when cash will hit the account and when bills come due.

For businesses juggling tight margins or significant debt obligations, this is the ultimate “can we pay the bills?” tool. It exposes “pinch points” in time to act—whether that means adjusting payment terms, negotiating with vendors, or tightening spending.

Even for businesses with ample short-term cash flow, the 13-week model builds cash discipline and highlights operational inefficiencies you might otherwise miss.

Best practices for maintaining your 13-week cash flow forecast:

  1. Build it straight from your bank data. Start with beginning cash, then layer in collections, disbursements, payroll, and debt service. This grounds your forecast in reality.
  2. Flag critical weeks. Look for points where cash dips uncomfortably low or loan covenants are at risk. Use conditional formatting or a traffic-light system (red/yellow/green) to make problem weeks impossible to miss.
  3. Act early. A shortfall flagged six weeks out is solvable through receivables collection, renegotiated payment terms, or a line-of-credit draw. A shortfall discovered two days out is a crisis.
  4. Keep it rolling. Update the forecast weekly. It’s not a “set and forget” tool. It’s a living dashboard for operational cash.

The 12-Month Rolling Forecast: Strategic Visibility

A 12-month rolling forecast extends your field of vision. Instead of tracking day-to-day liquidity, it projects financial performance across an entire year, updated every month to always include the next 12 months.

This forecast connects directly to strategy. Are you planning a new product launch? Considering a geographic expansion? Preparing for succession or an eventual exit? A 12-month forecast helps you understand whether today’s decisions put those bigger goals within reach or out of range.

It also gives lenders, investors, and partners confidence that you’re not only managing the week-to-week but also planning for the long game.

Best practices for maintaining your 13-month forecast:

  1. Tie it to your strategy. If you’re planning a new product launch in Q2 or a facility expansion in Q3, build those assumptions directly into the forecast. This links operations and finance.
  2. Layer in scenarios. Create best-case, base-case, and downside views. Business owners often focus on the optimistic line, but lenders and buyers will stress-test the downside.
  3. Update monthly. Each close should trigger an update. Rolling means rolling—you’re always looking 12 months forward, not stuck with a static annual plan.
  4. Use it for capital planning. A 12-month view tells you whether you’ll need to refinance debt, raise equity, or conserve cash to hit long-term goals.

Best Practice: Use Both

The most resilient businesses treat forecasting as a two-lens system. The 13-week forecast ensures survival and day-to-day stability. The 12-month rolling forecast ensures growth and sustainability.

Together, they give you the foresight and flexibility to make decisions with confidence, whether you’re navigating short-term pressures or mapping the future of your business.
