Accounts Receivable (Debitorenbuchhaltung)
Accounts receivable (AR, Debitorenbuchhaltung) is the sub-ledger that tracks customer invoices, payment terms, open items and collections. AR sits in the middle of the Order-to-Cash process and directly drives DSO (Days Sales Outstanding) and working capital. For DACH mid-market, AR carries specific German-tax requirements (umsatzsteuerliche Behandlung, GoBD-compliant retention) and increasingly e-invoicing obligations from 2025.
Core AR functions
- Customer master data with credit limit, payment terms, tax classification, default payment method
- Invoice posting — automatic from sales documents or manual journal entry
- Open-item management — outstanding invoices tracked with due dates, partial payment handling
- Cash application — match incoming payments to invoices, increasingly AI-driven
- Dunning — reminder sequences with configurable escalation, charges, language and tone
- Disputes and credit notes with audit trail of customer-facing actions
- Bad-debt provisioning — aging-based estimation, individual write-offs, recovery tracking
- Factoring integration — sale of receivables to factoring banks (BFS, GE Capital, Coface)
DACH-specific requirements
Umsatzsteuer (VAT): AR invoices in DACH carry German, Austrian or Swiss VAT depending on customer and shipment destination. ERP must apply correct VAT codes automatically based on customer master and product category. Reverse-charge (Reverse Charge Verfahren): B2B intra-EU sales typically use reverse-charge; the supplier issues invoices without VAT and the customer self-accounts. Mehrwertsteuer-Ident-Nummern: customer VAT IDs must be validated periodically against the EU MIAS database; ERP integrates with this validation. GoBD applies to AR invoices — 10-year retention in original electronic form, audit-trail integrity. e-invoicing: from 2025, B2B AR invoices in Germany must be issued in structured format (ZUGFeRD or XRechnung) for receivers requiring it.
Dunning workflows
German dunning practice typically follows a three-stage sequence: (1) Zahlungserinnerung (friendly reminder) after 7-14 days overdue, often automatic, polite tone. (2) Erste Mahnung (first dunning) after further 7-14 days, more formal, with dunning charges. (3) Zweite Mahnung / Mahnverfahren (second dunning / legal proceedings) after additional delay, frequently triggering the German Mahnverfahren (court-issued payment order) or transfer to a collection agency. Sophisticated AR teams use customer-specific dunning strategies based on customer history and relationship value — not all customers get the same treatment. ERP-side dunning engines (built into SAP, Dynamics 365, NetSuite, Sage) support multi-language, multi-channel (email, postal, customer portal) execution.
Automation opportunities
Three major AR automation areas drive meaningful improvement. (1) AI-driven cash application: match incoming payments to invoices automatically using ML on bank statements, achieving 85-95% straight-through processing. Specialist tools: HighRadius, BlackLine, Esker, Sidetrade. (2) Automated dunning: rule-based reminder workflows with customer-specific exceptions, integrated with email and customer portals. (3) Self-service customer portals: customers download invoices, view payment history, submit disputes and pay online. Reduces inbound support load by 40-60% in mature implementations. Mid-market investment in AR automation typically pays back within 12-24 months through DSO reduction, headcount efficiency and bad-debt avoidance.

Frequently Asked Questions
What is a healthy bad-debt ratio?
For DACH B2B mid-market, bad-debt write-offs below 0.5% of revenue are typical; 1-2% indicates collection issues; above 2% usually points to systematic credit-management problems. The healthy range depends on industry, customer base and credit-management discipline.
Should we factor our receivables?
Factoring (Verkauf von Forderungen) trades a 1-3% discount on receivables for immediate cash and credit-risk transfer to the factor. Worth considering when working-capital cost exceeds the factoring fee, or when customer credit risk is hard to manage in-house. German factoring providers: BFS Finance, GE Capital, Eurofactor, A.B.S. Global Factoring.
How does e-invoicing change AR workflows?
For outbound invoicing, e-invoicing produces structured XRechnung or ZUGFeRD invoices instead of PDF. The change is moderate — modern ERP generates these natively or via add-ons (JustOn, eEvolution, Cologne Intelligence). The bigger shift is on the customer side: structured invoices flow into customer AP automation, accelerating their payment cycles and your DSO.
