Why Marketing Agencies Owners Should Care
For marketing agencies, DSO is often your biggest cash flow killer. You pay team salaries every two weeks but clients pay net-30 (or later). A project might cost you $15K in labor before client pays $25K invoice 45 days later. High DSO means you're essentially a bank for your clients - lending them money interest-free for 30-60 days. Reducing DSO is the fastest way to improve agency cash flow.

Industry context: Retainers billed monthly net-15: 15-25 days. Projects (50% upfront): 20-30 days. Projects invoiced on completion: 40-60 days (poor). Above 40 days overall means collection problems or wrong payment terms.

How to Calculate Days Sales Outstanding (DSO)
Formula
(Accounts Receivable / Total Credit Sales) × Number of Days
In plain English
Average number of days customers take to pay their invoices
Example: Elevate Digital Marketing
Accounts Receivable Current month retainers + project balances | $45,000 |
Monthly Revenue Average monthly revenue | $40,000 |
DSO Calculation Cash collected in 5 weeks on average | $34 |
Calculation
($45,000 AR / $40,000 monthly revenue) × 30 days = 33.8 days DSO
At 33.8 days DSO, this agency is acceptable but not great. They're floating about 5 weeks of operations. Retainers are probably paying around 25-30 days, projects around 40-45 days. Could improve to 25-28 days with better payment terms.

How to Improve Your Days Sales Outstanding (DSO)
How to do it
New clients: "Retainer billed 1st of month, due 15th (net-15)." Existing clients: gradually transition. Offer 3% discount for net-7 payment. Use automatic ACH/card charging if possible.
Expected impact
Reduce retainer DSO from 35 to 18-20 days. On $28K monthly retainers, collect 2 weeks faster. Free up $12-15K working capital.
