AI in Accounting 2025: From E-Invoice Obligation to ROI Turbo
Pick up the pace now: 2025 is a turning point for finance departments. Mandatory e-invoicing in B2B transforms digital workflows from "nice-to-have" to standard - and AI transforms them into competitive advantage. Those who scale AI use cases in accounting, controlling and treasury reduce cycles, cut costs and increase compliance security.
Why 2025 becomes the tipping point
Regulation as tailwind: Since January 1, 2025, domestic companies must be able to receive and process e-invoices; the issuance obligation applies in stages with transitional regulations until the end of 2027. This forces comprehensive, machine-readable financial processes - the perfect foundation for AI automation.
The five fastest business cases in finance
1) Incoming invoices (AP) - Touchless First: Modern AP solutions achieve high automation rates: AI extracts data from PDFs, learns from corrections and reduces exceptions. Industry benchmarks show average costs per invoice of around $9.40 - Best-in-Class at approx. $2.78.
2) Receivables & Collections: Predictive models forecast payment receipts, prioritize reminder activities and improve DSO.
3) Closings & Accounting: SAP Business AI provides AI-assisted summaries, error explanations and Financial Insights in S/4HANA; Microsoft and Dynamics 365 integrate Copilot functions.
ROI calculation: Three scenarios for the CFO
Scenario A - AP Automation at 50,000 invoices/year: Benchmark costs drop from $9.40 to $2.78 per invoice. Potential: (9.40 – 2.78) × 50,000 ≈ $331,000 per year.
Scenario B - Quick wins with DATEV automation: The AI service "Invoice Automation Service" generates over 5.5 million booking suggestions per month for 56,000 companies.
