Money, Pricing & Model

What does healthy cash flow actually look like for a bootstrapped business, and how do I stop confusing revenue with money in the bank?

A starting point

Revenue is a promise, cash is what you can actually spend, and bootstrapped founders die in the gap between the two. Watch your cash runway weekly, get customers to pay upfront or in advance wherever you can, and never let a growing top line hide the fact that receivables are stuck in someone else's payment cycle. In India especially, assume every B2B invoice pays late until proven otherwise.

Why we picked it If the difference between revenue and cash in the bank still feels fuzzy, a short visual walkthrough makes it click faster than any spreadsheet. This one keeps it plain for founders without a finance background: revenue is what you have earned on paper, cash flow is what has actually moved through your account. That single distinction is what stops the confusion in the question.

Cash Flow vs. Profit: What's the Difference?
  • Revenue is booked when you deliver, not when the customer pays, so a profitable month can still leave your account empty.
  • Cash flow tracks the timing of money in and money out, which is what really keeps the lights on.
  • A business can be profitable and still run out of cash if payments arrive late.

Why we picked it Once you accept that the spreadsheet lied about your cash, this template makes the timing gap concrete: you enter your real starting cash, revenue, and monthly expenses and it lays out burn, net cash, and runway month by month. It is free with no email wall, and the scenario tabs let you test what happens if you cut a fixed cost or push a hire out. Plug in your actual numbers rather than trusting a single average burn figure.

Startup Runway Calculator Template (Excel and Google Sheets)

From The Startup Project by The Startup Project Downloadable spreadsheet, 15 to 30 minutes to fill in

  • Runway is just current cash divided by net monthly burn, and seeing it laid out month by month exposes the exact month you run dry.
  • Because it separates revenue, headcount, and expenses, you can watch how trimming one fixed cost (a hire, a tool, an office) moves your runway more than chasing a few more sales.
  • Model conservative, base, and aggressive cases so you are not planning off a single optimistic line.
