Open receivables in e-invoicing: data quality and automatic allocation

Since 2025, German VAT law treats only an invoice in a structured electronic format that enables electronic processing as an E-Rechnung (German structured electronic invoice). A simple PDF is generally a "sonstige Rechnung", meaning another form of invoice. Common formats include XRechnung and qualifying ZUGFeRD versions. For recovery, format alone is insufficient: mandatory data, performance, parties, invoice number, amount and payment terms must be correct. Technical validation helps but does not replace a contractual review. For the specific issue “data quality and automatic allocation”, this requirement should be recorded in the review note with its date and supporting evidence.

To ensure that “data quality and automatic allocation” is more than a headline, the file should evidence the decisive conditions with dates and sources. Unclear points should be logged as open review items rather than replaced by assumptions. In “data quality and automatic allocation”, this control determines whether the standard workflow applies or an individual review is required.

Domestic German businesses have had to be capable of receiving an E-Rechnung since 2025. Transitional rules apply to issuance: through 2026, another form of invoice may generally still be used; where the issuer had prior-year turnover of no more than EUR 800,000, the transition extends through the end of 2027. These transitions must not be confused with the receipt obligation. Businesses should define receipt channels, validation, approval, archiving and transfer to accounting and receivables management. For “data quality and automatic allocation”, the workflow should continue only after ownership, deadline and the exception route are clearly set in the system.

Operationally, this review point needs a named owner and a fixed deadline. The result should be stored with references to the evidence so that accounting, sales, legal and the external service provider work from the same facts. For “data quality and automatic allocation”, quality control should reconcile the balance and underlying entries once more against the original evidence.

For later recovery, the structured original file, a readable rendering, evidence of transmission or availability, validation record, performance evidence and payment terms should be archived together. For German VAT purposes, at least the structured part of the E-Rechnung must be retained in its original form. A defective invoice should be corrected transparently and resent, with the old and new versions linked by timestamp. This makes it possible to show which claim, version and delivery date are relied upon. In “data quality and automatic allocation”, this control determines whether the standard workflow applies or an individual review is required.

For portfolios, the review result should lead directly to a next action: clarification, reminder, Mahnung (German payment reminder), debt collection, gerichtliches Mahnverfahren (German court payment-order procedure) or individual legal review. Each action needs a deadline, channel and stop criterion. The outcome for “data quality and automatic allocation” should record the current balance, next date, reason for the decision and responsible person. The open-item list should show the current balance, status, owner and next action date for the case.

An incorrect recipient, calculation error, missing mandatory item or duplicate posting should be resolved before further reminders. The correction must identify which invoice it replaces or amends; credits and replacement invoices should be linked clearly. Receipt and any new due date depend on the contract and the type of error and should not be assumed automatically. For alleged duplicate billing, compare service period, order number, invoice items and payments side by side. Only the reconciled balance belongs in collection. For “data quality and automatic allocation”, quality control should reconcile the balance and underlying entries once more against the original evidence.

Quality control should detect the wrong legal entity, outdated addresses, duplicate invoices, unposted payments and unsupported ancillary claims. These errors weaken enforcement and place unnecessary strain on the customer relationship. For the specific issue “data quality and automatic allocation”, this requirement should be recorded in the review note with its date and supporting evidence.

A digital collection handover should include master data, statement of account, contract, invoice, performance evidence, reminders, objections, payments and current contact details. Every file must be clearly linked to the claim. Interfaces are useful for high volume; for smaller portfolios, a well-defined spreadsheet or portal transfer may be sufficient. Mandatory fields, formats, duplicate checks and status feedback should be agreed in advance. Sensitive data should enter the process only through secure channels and role-based access. The outcome for “data quality and automatic allocation” should record the current balance, next date, reason for the decision and responsible person.

Once the claim is coherent, due and sufficiently evidenced, the next escalation stage should be triggered without unnecessary delay. Fortis Inkasso GmbH & Co. KG can handle out-of-court recovery; disputed or procedural issues remain subject to individual legal review. For “data quality and automatic allocation”, the workflow should continue only after ownership, deadline and the exception route are clearly set in the system.
