The CFO's Monthly Checklist: 7 Financial Reviews That Prevent Cash Crises

The Discipline That Beats the Crisis

Most cash crises don't arrive as surprises — they arrive as slow leaks that nobody was watching. A customer quietly slips 30 days past due. A vendor tightens payment terms. A hiring plan outpaces the revenue it was supposed to support. By the time these show up on a bank balance, the damage is already three months old.

The difference between finance teams that get blindsided and those that don't isn't better software or smarter forecasting models — it's a monthly review cadence that forces uncomfortable questions before they become emergencies. Here are the seven reviews that belong on every CFO's calendar, every single month, no exceptions.

1. Accounts Receivable Aging, By Customer

A rising AR balance is meaningless on its own — revenue growth naturally grows receivables. What matters is the aging curve. Pull the AR aging report and look specifically at the 60-90 day and 90+ day buckets. Ask:

• Which customers moved into a worse bucket than last month?
• Is the slippage concentrated in a few accounts or spread across the book?
• Has any single customer's balance grown enough to become a concentration risk?

A customer sliding from 30 to 60 days is an early warning sign worth a phone call, not a write-off decision. Waiting until they hit 120 days means you've already financed their problem with your own cash.

2. Accounts Payable and Vendor Terms

The mirror image of AR review is just as important. Review upcoming AP obligations against your cash position for the next 30, 60, and 90 days. Specifically:

• Are any vendors tightening terms or requesting prepayment — often a signal they've heard something about your business, or are managing their own cash stress?
• Is a disproportionate share of payables concentrated with one supplier who could disrupt operations if the relationship sours?
• Are early-payment discounts being captured, or missed because nobody's tracking them?

Small and mid-sized businesses that fail often show tightening vendor terms months before the failure becomes visible elsewhere, according to research from the Federal Reserve Banks' Small Business Credit Survey — payment behavior is one of the earliest signals in the system.

3. Burn Rate and Runway, Recalculated From Actuals

Runway calculated once a quarter is runway calculated too late. Every month, recompute net burn using actual cash movements — not the budget, not last quarter's average. Break it into:

• Gross burn (total cash out) vs. net burn (cash out minus cash in)
• Burn rate trend over the trailing three months, not just the current month
• Runway in months at current burn, and runway under a stress-tested burn rate 20% higher

A single-month snapshot can mislead; a three-month trend tells you whether burn is stabilizing, accelerating, or improving.

4. Covenant and Facility Headroom

If the business carries any debt — a term loan, a line of credit, an SBA loan — covenant compliance deserves a monthly look, not just a review the week before the compliance certificate is due. Check:

• Current ratio, leverage ratio, and any fixed-charge coverage ratio against covenant thresholds
• Headroom trend — is the cushion shrinking month over month even if you're technically compliant?
• Available but undrawn credit line capacity, and whether the lender relationship supports a request for more if needed

Covenant breaches rarely happen overnight. They happen gradually, and lenders respond far better to CFOs who flag a tightening trend early than to those who show up in violation.

5. Revenue Concentration and Churn Signals

A monthly revenue review shouldn't stop at the top-line number. Break down:

• Revenue concentration by customer — what percentage comes from your top five accounts?
• Net revenue retention trend for subscription or contract-based revenue
• Any usage, engagement, or support-ticket signals suggesting a key account is disengaging before the contract renewal date

Losing your largest customer is a cash flow event, not just a revenue event. Seeing it coming gives you months to backfill the pipeline instead of scrambling after the fact.

6. Headcount and Payroll Against Plan

Payroll is usually the largest recurring cash outflow, and it's also the outflow most likely to drift silently from plan. Monthly, compare:

• Actual headcount and fully-loaded payroll cost against the approved plan
• Time-to-fill for open roles — slow hiring can mask an over-budget plan for months
• Contractor and overtime spend, which often absorbs headcount pressure without showing up in headcount reports

Payroll creep is one of the most common reasons budgets and cash forecasts diverge, and it compounds every month it goes uncorrected.

7. Scenario Stress Test Against a Cash Floor

Finally, every month, run a simple stress test: what happens to the cash balance if the largest customer pays 30 days late, if a planned raise or facility draw slips a quarter, and if one major expense line runs 15% over? Compare the resulting trough against your minimum operating cash floor.

This isn't about predicting the future precisely — it's about knowing, every single month, how much margin for error the business actually has.

Building the Habit

None of these seven reviews requires sophisticated tooling. What they require is discipline: a fixed date each month, a consistent format, and a willingness to escalate uncomfortable trends instead of waiting for them to resolve on their own.

Key takeaways:

• Cash crises are almost always visible in the data months before they hit the bank account — the failure is usually one of attention, not information.
• AR aging, AP terms, and covenant headroom are leading indicators; the bank balance is a lagging one.
• Recalculate burn and runway from actuals monthly, and stress-test against a defined cash floor rather than a single-point forecast.
• Payroll drift and revenue concentration are the two most common blind spots in otherwise well-run finance functions.
• The goal isn't a perfect forecast — it's a repeatable monthly rhythm that surfaces problems while there's still time to act on them.
