DSO (Days Sales Outstanding) measures how many days it takes a company to collect its credit sales. Each additional day of DSO means locked capital that cannot be invested. According to the Atradius Payment Practices Barometer 2025, 47% of B2B invoices in Western Europe are overdue. Spain has a particular problem: it consistently collects later than the European average.
The DSO landscape across Western Europe
Average payment terms in Western Europe rose to 52 days from invoicing (up from 41 days the prior year), per Atradius 2024. The differences between countries are stark: Finland offers the most generous terms (71 days), Greece the strictest (32 days on paper). Spain and Italy share the structural problem of late payments, with Spain's effective collection period running approximately 15 days above the European average at around 80 days.
Why does Spain collect later?
Payment culture: there is greater social tolerance for late B2B payments. Requesting timely payment is often perceived as a sign of financial weakness.
Business structure: Spain's economy is dominated by SMEs with less negotiating power against large buyers, creating asymmetry where smaller suppliers absorb the financial cost.
Regulatory framework: while Spanish law sets a 60-day maximum, actual compliance is limited. The Crea y Crece law with mandatory e-invoicing aims to bring transparency.
The real impact on your business
For a company with 5 million euros in credit sales, each day of DSO equals approximately 13,700 euros of locked capital. At a DSO of 75 days (60 agreed + 15 delay), over one million euros sits trapped in receivables. In Spain, 42% of B2B invoices are paid late and bad debts represent 6% of invoices (Atradius 2025).
How to reduce your DSO to virtually zero
Digital Trade Credit platforms transform this equation: the seller gets paid in 24 hours regardless of the terms agreed with the buyer. Effective DSO drops from 60-90 days to 1 day, freeing over one million euros in the example above and completely eliminating delay risk.
What is coming: e-invoicing and traceability
Spain's Royal Decree 238/2026 (published March 31, 2026) mandates electronic invoicing for all B2B transactions. Invoice statuses (issuance, acceptance, payment) must be reported within 4 days. For the first time, there will be verifiable, real-time data on actual payment timelines.
