The Cash Flow Mistake Most Agencies Make

Published October 8, 2025

You've just landed a big client. Revenue is up. The P&L looks great. But somehow, you're still scrambling to make payroll. Sound familiar? You're not alone, and you're making the same cash flow mistake most agencies make.

The Core Problem

Profit ≠ Cash
Your P&L shows revenue when invoiced. Your bank shows cash when paid. The gap can kill you.
30-60 Day Gap
Typical time between invoicing and getting paid. Your costs don't wait.

The Problem: Confusing Profit with Cash

Here's the issue: your profit and loss statement shows revenue when you invoice a client, not when they actually pay you. Meanwhile, you're paying your team, your software subscriptions, and your office rent in real time.

This timing mismatch is what kills agencies. You can be profitable on paper while running out of cash in reality.

The Timing Mismatch That Kills Agencies

Day 1: You win the project
P&L impact: None yet
Day 1-30: You do the work
Cash out: Salaries, tools, overheads paid immediately
Day 30: You invoice
P&L shows revenue. Bank balance: Still waiting.
Day 60-90: Client finally pays
Cash in—but you've been covering costs for 2-3 months

Why Agencies Are Especially Vulnerable

ChallengeImpactCash Flow Effect
Long Payment TermsClients pay 30-60 days after invoicing2 months of costs before cash arrives
Upfront CostsTeam and tools paid before clients payNegative cash flow on every project start
Project-Based WorkRevenue is lumpy, costs are consistentUnpredictable cash position
Scope CreepExtra work without extra paymentMargin erosion, longer payment cycles

The Solution: Cash Flow Forecasting

The fix isn't complicated, but it requires discipline. You need to forecast your actual cash flow alongside your revenue. (For a complete step-by-step guide, check out our simple forecasting framework for agency growth.)

Track Actual Payments

Record when invoices are actually paid, not when issued. This is your real cash position.

Map Your Expenses

Know exactly when payroll, rent, and other costs are due. No surprises.

Rolling 13-Week Forecast

Update weekly to stay ahead of cash crunches. 13 weeks gives you time to act.

Identify Danger Zones

Spot periods where cash will be tight before they happen. Plan ahead.
