A plan with assumptions
you can explain.

Choose LivePlan for an integrated forecast-and-scenario workflow, Upmetrics for a business plan with an associated financial forecast, or a template-led route when you want direct control of the narrative and spreadsheet. Start with the customer problem and make the cash timing explicit.

Choose the planning workflow, then the software

This focused comparison uses official documentation. Recommendations are editorial judgments about workflow fit, not vendor tests or promises of funding.

LivePlan

The official forecasting page describes financial forecasts and scenarios, connecting budgets to financial reports and cash-flow planning.

Consider it when: you want to explore financial scenarios within a dedicated business-planning product.

Check the actual plan’s forecasting, export and collaboration access. Review the assumptions behind generated statements with someone qualified to assess your business.

Official forecasts and scenarios overview

Upmetrics

Its forecast setup guide describes choosing the forecast start, fiscal year and plan duration, including starting a forecast from scratch. The forecast is a defined part of the business-planning workflow.

Consider it when: you want a guided plan alongside an organized forecasting setup.

Confirm report formats, available collaboration and the data inputs your actual subscription supports. AI-generated prose or estimates still need review.

Official forecast setup guide

Template + spreadsheet

The U.S. Small Business Administration distinguishes traditional and lean business-plan formats. Its guide covers the narrative components and selecting a format that fits your needs.

Consider it when: you want control over the document and can maintain the financial model separately.

This is a workflow rather than a dedicated software product. If someone requests a plan, confirm their required sections, financial statements and assumptions first.

Build a brief and trace the cash

Enter your own narrative and a twelve-month unit-sales scenario. Every demo figure is fictional. Decimal.js calculates sales, cash receipts and outflows from your inputs; it does not predict customer demand. This simplified model is not a full accounting forecast.

Units sold by month

Enter nonnegative whole units. There is no automatic growth or hidden conversion rate.

MonthUnitsSalesCash receiptsVariable outflowFixed outflowStartup outflowClosing cash

Cash receipts use the selected whole-month delay. No opening receivables, financing inflows, returns, bad debts, inventory timing, taxes or debt service are included. Enter labor and other recurring cash costs in fixed/variable inputs where appropriate. All cash costs are paid in the sales month, startup outflow is month 1, and displayed currency values round to two decimals. Optional saved scenarios remain in this browser until deleted; no scenario upload occurs.

Make the narrative and numbers agree

A cash table is most useful when every assumption has a reason.

Explain the customer before the market size

Describe who buys, the problem they have and how your offer addresses it. Separate evidence already collected from hypotheses still to validate. A broad market statistic does not prove that customers will buy your specific offer.

Choose the plan format for the reader

A concise planning brief can guide early decisions. A lender or investor may require more detailed sections, statements and supporting material. Use the SBA outline as a starting point and ask the recipient what they need before expanding the document.

Distinguish sales from cash receipts

A sale recorded in one month may be collected later. This tool shifts the entire sales amount by zero, one or two months; it assumes collection in full. Sales still unpaid at the end remain uncollected within the scenario. A negative closing balance identifies a gap under your assumptions; it does not automatically add funding.

Keep the accounting scope clear

Monthly sales = units × price. Cash receipts = sales from the month selected by the delay, with zero opening receivables. Variable outflow = units × variable cash cost. Closing cash = previous closing cash + receipts − variable outflow − fixed outflow − startup outflow. The table is a simplified cash movement model, not profit, a balance sheet or a tax calculation.

Questions to resolve before committing

Can AI write the plan?

Writing assistance can organize a draft, but it does not provide evidence that an offer works. Check every factual claim and financial assumption. Never treat generated competitor details or sales figures as research.

Why does sales exceed cash?

With delayed collection, the final months can include sales not yet received in cash. The output reports those uncollected sales. They are a modeled timing difference, not proof of collectible real receivables.

What should I do with a cash gap?

Revisit the timing and costs using real evidence. Discuss financing, obligations and the appropriate full forecast with qualified advisers. This workbench shows your scenario; it does not recommend borrowing or spending.

Turn assumptions into questions you can test

Export the brief, record what evidence would change the plan and update the numbers as actual results arrive.
