DSO Benchmarks by Industry
Days Sales Outstanding varies significantly across industries. Businesses with longer project cycles or complex billing (like construction) naturally have higher DSO, while retail operates on much shorter collection windows.
| Industry | Average DSO | Typical Range |
|---|---|---|
| IT / Software Services | 50 days | 35 - 65 days |
| Construction | 83 days | 60 - 100 days |
| Manufacturing | 55 days | 40 - 70 days |
| Healthcare | 65 days | 45 - 85 days |
| Professional Services | 45 days | 30 - 60 days |
| Retail | 8 days | 3 - 15 days |
| Wholesale | 35 days | 25 - 50 days |
| Transportation | 42 days | 30 - 55 days |
How to Reduce Your DSO
A lower DSO means you are collecting payments faster, improving cash flow and reducing the risk of bad debt. Here are proven strategies to bring your DSO down.
- Send invoices immediately after delivering work or goods. Every day you delay invoicing adds a day to your DSO.
- Use automated payment reminders to follow up at regular intervals. Tools like TapDue send multi-step reminders so you never have to manually chase payments.
- Offer early payment discounts such as 2/10 Net 30 (2% discount if paid within 10 days). This incentivizes faster payment without damaging the relationship.
- Review credit terms for slow-paying customers. Consider shortening Net 60 terms to Net 30, or requiring deposits for high-risk accounts.
- Accept multiple payment methods including credit cards, ACH, and digital wallets. The easier you make it to pay, the faster you get paid.
- Follow up on overdue invoices within 48 hours. The longer an invoice goes unpaid, the less likely it is to be collected at all.
