The 8-Point Monthly Runway Review Checklist for Seed-Stage Startups

Most seed-stage founders learn their runway number the week a board deck is due. That is a terrible time to learn it. Runway moves every month — a payroll run, a late invoice, an annual insurance premium, a new hire who starts on the 15th — and each move quietly changes how many months of decisions you still get to make. A monthly review, done in under an hour, keeps that number honest without turning finance into a second job. Here is the checklist worth running, in order.

1. Pull the Real Cash Balance, Not the Dashboard Balance

Start with bank reality. Export balances from every account: operating, payroll, tax withholding, savings or treasury, and anything held in another currency. Add them up, then subtract what is not actually yours to spend — a customer deposit you may have to refund, withholding you owe, a check written but not yet cleared.

Three checks catch most errors:

• Reconcile the bank balance against your accounting system. A gap larger than a rounding error means someone recorded a payment that never left, or a receipt that never arrived.
• Note uncleared checks and scheduled transfers. Money in transit is not money you can use.
• Freeze the figure. Write it at the top of the sheet with the date. Runway arguments usually come from two people using two different "cash" numbers.

Where founders get this wrong

Mixing restricted cash into spendable cash, and treating a signed-but-uncollected invoice as if it were already in the bank. Both make the month feel better and the quarter feel worse.

2. List Committed Spend, Not Just Last Month's Spend

Historical burn tells you where money went. Committed spend tells you where it is already going. Pull every obligation that will consume cash whether or not you do anything this month:

• Payroll, payroll taxes, and benefits for the current team
• Signed contracts with notice periods — cloud hosting, data providers, recruiters, office space, insurance
• Annual or quarterly bills landing this month and next
• Equipment, licensing, and onboarding costs for people who have already accepted offers
• Debt repayments, financing fees, and any revenue-share obligations

Then mark what you could stop, and how long it would take. A vendor with a 90-day notice clause is much closer to fixed cost than a monthly subscription you can cancel on Friday. That distinction is what makes the scenarios in section six useful instead of theoretical.

3. Separate Inflows Into Three Buckets

Inflow optimism is the most common way runway gets overstated. Sort every expected receipt into one of three buckets:

1. In the bank. Cash received, plus invoices with a confirmed payment date.
2. Likely. Signed contracts with a realistic collection window, based on how that customer has actually paid before — not how the contract says they should.
3. Hopeful. Pipeline, undiscussed renewals, grants awaiting approval, rebates you have not received.

Only the first two belong in the base case. Keep the third on its own line and label it. If your runway only works when hopeful money arrives, you do not have that runway.

4. Re-check the Hiring Plan Against the Cash Number

Hiring is the largest lever a seed-stage company has, and the one most often planned in a spreadsheet that never talks to the runway model. For each open role, write down the start month, the fully loaded monthly cost (salary, taxes, benefits, equipment, software seats), recruiting fees, and any relocation spend.

One habit worth keeping: run the model with every planned hire starting a month later than scheduled. New hires rarely start on time, and that delay should make runway longer, not shorter. If a delayed hire still shortens runway, the role is being funded by hope.

Do not forget attrition and backfills. A resignation in a critical role usually becomes an unplanned hire at a higher salary than the person who left.

5. Produce Three Numbers, Not One

One runway figure invites debate. Three ends it:

• Net burn: cash out minus cash in for the month, using actuals.
• Gross runway: cash today divided by the trailing three-month average net burn.
• Plan runway: cash today measured against modeled burn, including hires and committed spend you have already approved.

Post all three in the same place every month. When gross runway and plan runway diverge by more than a couple of months, that gap is the agenda for the meeting — not a footnote.

6. Set Scenario Triggers Before You Need Them

Decide in advance what you will do at certain levels, and who does it. Triggers work best when they are specific, dated, and owned by a named person.

If plan runway falls below nine months, hiring pauses for all roles except one pre-agreed critical position, and the founder owning finance re-forecasts within five business days.

A few more that hold up in practice:

• If cash falls below a set floor, freeze new vendor contracts above an agreed monthly threshold.
• If collections miss forecast two months in a row, run a collections sprint and re-forecast the quarter.
• If no term sheet exists by a set date, start the bridge conversation with existing investors.
• If a major customer gives notice, rebuild the model the same week rather than at month end.

Write them down. A trigger agreed in a calm month is far easier to act on in a stressful one, and it removes the temptation to re-litigate the decision when you are least clear-headed.

Make the Ritual Boring

The goal is not a perfect forecast. It is a repeatable one: same sheet, same order, same day each month, ideally before payroll runs. Keep the last twelve months of reviews in one folder so you can see whether your forecasts were consistently optimistic, and by how much. Founders who adjust for their own bias make better calls than founders who keep trusting the same spreadsheet.

Two practical notes. First, delegate the data gathering — pulling balances, exporting the ledger, updating the hiring tab — but keep the interpretation with whoever owns the bank account and the hiring plan. Second, this is a planning routine, not accounting advice; how you treat deferred revenue, sales tax, grants, and equity-based compensation should be confirmed with your accountant, since those treatments change the number you are looking at.

Do this monthly and the runway conversation stops being a quarterly surprise. It becomes a short, slightly dull meeting with a list you already know how to run.
