Days Sales Outstanding Benchmarks 2026: 40.12-Day Median DSO [Data]

Key Takeaways

The median US company’s Days Sales Outstanding reached 40.12 days in Q1 2026, up from 38.00 days a year earlier (Credit Research Foundation, National Summary of Domestic Trade Receivables).
The median company’s actual DSO sits 8.53 days above its own Best Possible DSO of 31.59 days, the gap credit teams call collection slippage (CRF NSDTR, Q1 2026).
Among the largest 1,000 US public companies, top-quartile performers collect 18 days faster than the median, a gap worth $600 billion in trapped working capital (The Hackett Group, 2025 US Working Capital Survey).
Europe’s largest public companies run a higher median DSO of 48.5 days, up 1% year over year (The Hackett Group, 2025 European Working Capital Survey).
AR-automation vendor Billtrust’s own client base averaged 39 days DSO in 2025, down from 45 days in 2024, while 44% of organizations surveyed report DSO above 60 days (Billtrust 2026 Accounts Receivable Benchmark Report).
The global average B2B invoice takes 51 days door to door, a related but distinct measure from formal DSO (Sidetrade Data Lake, 285 million invoices, 2026).

The median US company’s Days Sales Outstanding reached 40.12 days in the first quarter of 2026, according to the Credit Research Foundation’s National Summary of Domestic Trade Receivables. That is up from 38.00 days a year earlier, and it sits 8.53 days above what CRF calls the median company’s own Best Possible DSO. Company size and geography explain most of the rest of the spread, and one factor keeps showing up on the fast side of every benchmark below: consistent, automated follow-up on unpaid invoices.

What is Days Sales Outstanding, and what counts as a good benchmark in 2026?

Days Sales Outstanding measures the average number of days it takes a business to collect payment after a sale is made on credit, calculated as accounts receivable divided by total credit sales, multiplied by the number of days in the period. A lower DSO means cash is converting from invoice to bank balance faster. The broad US benchmark for Q1 2026 is 40.12 days, per the Credit Research Foundation’s National Summary of Domestic Trade Receivables (NSDTR), a quarterly survey CRF has run since 1960. That is up slightly from 40.50 days the prior quarter and 38.00 days a year earlier, so the median company’s collection cycle has stretched by roughly two days over the past twelve months. CRF also publishes a Best Possible DSO figure for the same quarter, 31.59 days, calculated from the theoretical fastest collection achievable given actual sales patterns. The 8.53-day gap between the two is what separates an average collection process from a disciplined one.

How big is the gap between top-performing and median companies?

The gap is large enough to matter at a portfolio level, not just a single business. Among the 1,000 largest US publicly traded nonfinancial companies, top-quartile performers on DSO collect roughly 18 days faster than the median company, a difference the Hackett Group’s 2025 US Working Capital Survey values at $600 billion in trapped working capital across that population. The same survey found the cash conversion cycle for this group improved 4% to 37 days overall, driven mostly by a 3% improvement in days payable outstanding to 59 days, while DSO itself worsened slightly for a second consecutive year. Billtrust’s 2026 Accounts Receivable Benchmark Report, citing the Hackett Group’s benchmarking, puts the underlying figures at a 46-day median against a 28-day top-performer figure, an 18-day spread that matches Hackett’s own reported gap.

How does DSO differ between the US and Europe?

Geography adds another layer on top of company-size differences. The Hackett Group’s 2025 European Working Capital Survey, covering the 1,000 largest European-headquartered nonfinancial companies, found a median DSO of 48.5 days, up 1% year over year and part of a third consecutive year of cash conversion cycle deterioration for that group. That is roughly 8 days higher than CRF’s broad 40.12-day US median for the same period, though the two figures come from different populations and methodologies: CRF surveys domestic trade receivables across US industries generally, while Hackett’s benchmark covers only the largest public companies in each region. Billtrust’s own AR-automation client base, a smaller and self-selected group already using collection tooling, reported the lowest figure in this set at 39 days.

What does a high DSO actually cost, and who is exposed?

The dollar cost scales with company size, but the underlying exposure is common across business sizes: cash that should already be in the bank is sitting in accounts receivable instead. Billtrust’s 2026 Accounts Receivable Benchmark Report, drawing on analysis across thousands of organizations and access to more than $1 trillion in annual B2B transaction data, found that 44% of organizations report DSO above 60 days, and 21% report DSO above 90 days. At the large-company end, Hackett’s 2025 survey found $1.7 trillion trapped in excess working capital across the top 1,000 US public companies, 35% of their gross working capital and 11% of aggregate revenue combined across receivables, payables, and inventory.

Does accounts receivable automation actually lower DSO?

The data suggests it does, at least directionally. Billtrust’s clients, businesses already using AR-automation tooling, averaged 39 days DSO in 2025, down from 45 days in 2024, a roughly six-day improvement while the broader CRF benchmark moved in the other direction over the same window. The same report found that invoices paid through an integrated payment product shaved DSO down further still, to 38 days. None of that is a guarantee for any single business, since a self-selected group of AR-automation customers is not a random sample of every US company, but the direction lines up with what closes the CRF’s 8.53-day gap between actual and Best Possible DSO in the first place: consistent follow-up on every unpaid invoice rather than occasional, manual chasing. A payment reminder sequence that runs on autopilot is what CRF’s Best Possible DSO metric effectively assumes happens every time, on every invoice, without a credit team having to remember to send it.

How does DSO connect to late payment and invoice payment time?

DSO is a company-level accounting measure, but the invoice-level data behind it tells the same story. 55% of all US B2B invoiced sales were overdue in 2025, according to Atradius’s Payment Practices Barometer, which is one reason the median company’s actual DSO runs well above its Best Possible DSO rather than matching it. Globally, the average B2B invoice takes 51 days to collect door to door, per Sidetrade’s Data Lake study of 285 million invoices, split between roughly 32 days of agreed contract terms and 19 days of delay beyond them. Australian small businesses are a notable outlier on the fast end, paid in an average of 24.1 days, per Xero’s Small Business Insights for the March 2026 quarter, close to CRF’s Best Possible DSO figure and well under every other benchmark in this article.

The Bottom Line

Every DSO benchmark in this article points the same direction: the gap between a company’s actual collection speed and its achievable best isn’t explained by luck or a difficult customer base, it’s explained by process. CRF’s own Best Possible DSO calculation assumes every invoice gets collected as fast as the business’s own payment terms and customer mix allow, and the 8.53-day gap between that number and the median company’s real 40.12-day DSO is the size of the opportunity sitting in slow, inconsistent follow-up. A BillyPaid invoice ships with a payable link and automated reminders by default, so the follow-up piece of that gap is handled the moment an invoice goes out rather than something a credit team has to remember to do manually.

Frequently Asked Questions

What is a good Days Sales Outstanding benchmark in 2026? The broad US median is 40.12 days, per the Credit Research Foundation’s National Summary of Domestic Trade Receivables for Q1 2026. CRF’s own Best Possible DSO benchmark for the same period is 31.59 days, so a DSO close to the low-30s range is closer to best-in-class than the median company achieves.

How much does DSO vary between average and top-performing companies? Among the largest 1,000 US public companies, top-quartile performers collect roughly 18 days faster than the median company, a gap the Hackett Group’s 2025 US Working Capital Survey values at $600 billion in trapped working capital.

Is DSO the same everywhere in the world? No. The Hackett Group’s 2025 European Working Capital Survey puts the median DSO for the largest 1,000 European companies at 48.5 days, higher than the CRF’s 40.12-day US median for the same period.

Does accounts receivable automation actually lower DSO? Billtrust’s 2026 Accounts Receivable Benchmark Report found its own AR-automation clients averaging 39 days DSO in 2025, down from 45 days in 2024, while 44% of organizations surveyed report DSO above 60 days.
