“In an audit we have to be able to explain the approval process. Who decided what, and when?”

Document management for financial services: Traceable document processes for external audits, BaFin and internal audit

Pain points

Four things we hear from financial accounting every day

Chances are one or more will sound familiar.

“We lose money on every early payment discount because invoices sit in an email inbox for three days.”

“Four-eyes approvals run through Excel lists, and nobody knows who is still missing.”

“Every time someone queries a posting, we search several folders for the voucher.”

“Loan files sit partly in the core system, partly on the network drive, partly on desks.”

Use Cases

Document processes in finance

From the loan file to the e-invoice: supporting regulatory requirements in a structured, traceable way.

1

Digital loan file & contract archiving

Problem

Loan files grow over years, with documents scattered across different systems. During audits, records are missing or out of date.

Solution

Automatic file structure per borrower, all documents archived with versioning, access log for compliance, notification on expiry dates.

Result
Notably

less audit preparation time, complete traceability of all document changes (based on experience).

2

Automated e-invoice processing (ZUGFeRD / XRechnung)

Problem

E-invoicing mandatory from 2025: heterogeneous inbound formats, no uniform validation process, manual checking ties up capacity.

Solution

Automatic detection and validation of XRechnung & ZUGFeRD, error reporting, documented handover to approval and the accounting system.

Result
EN 16931

structured e-invoice intake since 2025, less manual rework.

3

Document management aligned with GDPR

Problem

Customer data and financial documents have to be retained under strict GDPR rules and deleted on request, which is hard to control manually.

Solution

Automatic deletion deadlines and retention rules, a subject access workflow for data subject rights, document access logged traceably.

Result
GDPR-oriented

data subject requests can be handled in a structured way, final GDPR compliance depends on configuration and Verfahrensdokumentation.

Accounts payable for financial services: auditable, approval-ready, traceable
