Order-to-Cash (O2C) describes the end-to-end process of fulfilling a customer order and collecting the associated payment. O2C spans sales, fulfilment, delivery, invoicing, receivables management and collections — typically the single largest revenue-cycle process in any ERP-bearing organisation. Optimising O2C directly affects DSO (Days Sales Outstanding), working capital, customer satisfaction and profit margin. For mid-market in Germany, Switzerland and Austria, O2C is the most-measured and most-automated end-to-end process.
Collections and dunning — reminder sequences, escalation to collections, legal proceedings if needed
Cash application — bank statement processing, payment-to-invoice matching, exceptions handling
Key O2C metrics
DSO (Days Sales Outstanding) — average days from invoice to payment. DACH mid-market benchmark: 30-50 days for B2B
OTIF (On-Time-In-Full) — percentage of orders delivered on time and complete. Benchmark: 90-98%
Order-cycle time — from order entry to delivery. Industry-dependent
Invoice accuracy — percentage of invoices accepted by customers without dispute. Target: > 95%
Bad-debt write-off ratio — percentage of revenue written off. Benchmark: under 0.5% for healthy operations
Cash-application straight-through processing — percentage of payments matched without human intervention. Target: > 85%
Automation opportunities
O2C is one of the most-automated ERP processes. Order entry: EDI for B2B, e-commerce APIs for online, AI-based PDF/email order extraction for unstructured channels. Pricing: rule-based engines apply customer-specific contracts automatically. Credit management: real-time integration with credit-insurance providers (Atradius, Coface, Allianz Trade) updates limits automatically. Invoicing: structured e-invoicing (XRechnung, ZUGFeRD) replaces PDF and paper. Cash application: AI-driven matching (HighRadius, BlackLine, Esker) reaches 85-95% straight-through. Collections: automated dunning workflows with escalation. Mature O2C automation programmes reduce DSO by 5-15 days, cut manual order-processing effort by 50-70%, and free finance team capacity for higher-value activities.
DSO optimisation in practice
Mid-market organisations typically find DSO improvement across four levers. (1) Invoice quality: structured e-invoices with embedded reference data reduce customer-side processing time. (2) Payment terms discipline: enforcement of agreed terms in master data, with non-standard terms flagged for approval. (3) Proactive collections: contact customers before due date for high-value invoices. (4) Self-service customer portals: provide customers with online invoice download, payment status and dispute submission. Companies pursuing all four levers consistently report 7-15 days DSO reduction over 12-24 months, with each day of DSO improvement worth roughly 0.3-0.5% of annual revenue in freed working capital.
What is a realistic DSO for B2B mid-market in DACH?
30-50 days for healthy operations, with payment terms typically 30 days net (sometimes 14 or 60). DSO above 60 days indicates collection issues or systematically late-paying customer base. Below 30 days indicates either tight payment terms, early-payment discounts, or a B2B-with-prepayment model.
Should we offer early-payment discounts?
Sometimes. 2% / 10 days net 30 (Skonto) is the classical German term. The effective interest cost (around 36% annualised) is high; it makes sense only when the alternative is more expensive (working capital financing, factoring) or as a customer-relationship tool. In low-interest-rate environments, Skonto offers shrink; in higher-rate environments, they grow.
How does AI-based cash application work?
AI cash-application reads incoming bank statements, extracts payment metadata (reference numbers, amounts, payer details), matches against open invoices in the ERP using fuzzy-matching and ML, and posts cleared invoices automatically. Modern tools (HighRadius, BlackLine, Esker, Sidetrade) reach 85-95% straight-through processing; the human team handles only exceptions. Implementation effort: 3-9 months and 100,000-500,000 EUR for mid-market AR teams.
