DSO (Days Sales Outstanding) is a key indicator for any company. It represents the average number of days required to collect trade receivables. A high DSO can quickly put pressure on your cash flow and undermine your company’s profitability. Conversely, a controlled DSO is synonymous with effective receivables management and financial security. In this article, discover how to sustainably improve your DSO through a combination of best business practices and intelligent automation with Aston AI, your SaaS customer collection software.
Why DSO is a strategic indicator
- It directly reflects the company’s ability to convert sales into cash.
- It influences WCR (working capital requirement) and therefore available cash.
- It impacts the perception of financial partners (banks, investors).
- It helps identify commercial, contractual or administrative malfunctions.
- It is a powerful lever for negotiating short-term financing lines.
DSO calculation method
The classic formula is:
DSO = (Accounts receivable / Sales incl. VAT) × 360
This formula can be refined by using only overdue receivables, or by including credit notes. Tools such as Aston AI can be used to visualize DSO overall, by customer segment, by geographical area or by salesperson.

Forecasting DSO: steering the future
DSO is not just a past indicator. Thanks to Aston AI’s predictive modules, it becomes a tool for projecting cash flow 30, 60 or 90 days ahead. Anticipate drift, model customer delay scenarios, adapt short-term financing: DSO becomes a strategic steering lever, no longer just a KPI for closing accounts.
Impact of DSO on company valuation
A controlled DSO means a better WCR, and therefore less short-term debt and a reduced need for financing. This has a direct impact on the evaluation of a company’s financial performance in the event of a fund-raising, sale or audit. This is a strong positive signal to investors, which is often overlooked by SMEs and SMIs.
FAQ - 4 questions every credit manager has about DSO
Q: My DSO is stable but my cash flow is deteriorating. Why?
A: Overall DSO sometimes masks sectoral drift. Aston AI makes it possible to analyze DSO by customer, by zone or by product.
Q: What is the right target DSO?
A: It depends on your sector, but aiming for a gradual reduction of 5 to 10 days can generate an immediate cash effect.
Q : My sales reps are slowing down their follow-ups. What can I do?
A: Involve them with cash indicators in their bonuses and real-time at-risk customer alerts.
Q: Is DSO really useful if I have cash?
A: Yes, because it structures your invoicing, reminder and follow-up discipline. A healthy cash flow doesn’t justify neglecting accounts receivable.
