Every funded startup knows its runway. The founder checks it monthly, the board reviews it quarterly, and investor memos lead with it. Runway is the first number that matters in a business with no revenue and the first number that matters in a business with revenue too — because revenue is lumpy and rent is not. Today, runway lives on the InvoiceUp dashboard for every solo business.
The math is trivial. Cash on hand, divided by monthly net burn, equals months of runway. A child could compute it. The reason no invoicing tool shows it is that it requires one input the tool doesn't already have: how much you actually spend every month. We added that input. Two numbers in settings and the runway card unlocks.
The headline is your current runway in months. Green if healthy (over 6 months), amber if under 6, red if under 3. Below that, three stress-test scenarios: what happens if your biggest client pauses (using the concentration numbers we shipped last week), what happens if you raise rates by 15%, and what happens if your expenses grow by 30%. This is the same triangulation every real CFO runs on an enterprise budget — compressed into a dashboard card.
The "current cash" number isn't just your savings. It adds the expected income from the next 30 days using the cashflow forecast — so the runway you see is the runway you'll actually live through, not a pessimistic snapshot that ignores the invoices about to clear.
Runway isn't a VC metric. It's the question every business has to answer every month. Most solos just avoid answering.
The baseline runway reassures you. The stress tests tell you the truth. If your business survives your biggest client pausing for a quarter, you're fine. If it doesn't, you need to either diversify (the concentration card told you which client to worry about) or increase reserves. The gap between the baseline and the worst-case scenario is the gap between how safe you feel and how safe you are.
Neither your monthly burn nor your cash on hand leaves your account. Both numbers stay in Dekimu's storage, encrypted at rest, and never appear in any aggregated metric, marketing material, or cross-tenant query. You are not the product, and your private finances are nobody else's business — including ours.
This is the third piece of the financial cockpit — concentration, cashflow, and runway — that no freelance invoicing tool has ever bundled at any price point. Together they are exactly the upgrade that justifies the jump from hobby-tier pricing to a real subscription. One coherent story: here is what you are exposed to, here is what is coming, here is how long you have if any of it goes wrong.
