Invoice is not paid because of an invoice error: correct, resend and set a deadline

Reviewed: 2026-07-26. This article, “Invoice is not paid because of an invoice error: correct, resend and set a deadline”, explains a specific part of debt recovery under German law. The first task is to distinguish a due and substantiated claim from booking errors, legitimate objections and simple delay. Before collection, the reconciled balance must be established after corrections, credits and payments. A documented workflow protects liquidity, evidence and the customer relationship. The information is general and does not replace a review of the individual case.
Correct invoice errors and alleged duplicate billing
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 the specific issue “correct, resend and set a deadline”, this requirement should be recorded in the review note with its date and supporting evidence.
For “correct, resend and set a deadline”, the starting point is not the reminder stage but a verified set of facts. The reviewer records the legal basis of the claim, contracting party, amount, due date, receipt and payments before drawing a legal or operational conclusion. In “correct, resend and set a deadline”, this control determines whether the standard workflow applies or an individual review is required.
Reconcile bank entries, customer ledgers and credits
Before a reminder is sent, incoming payments, bulk transfers, returned debits, discounts, credit notes and set-offs should be reconciled with the customer ledger. Unidentified payments belong on a separate working list with an owner and clarification deadline. Automated matching may use amount, reference, IBAN, invoice number and tolerances, but exceptions must remain visible. A supposedly open claim should not be handed to collection while a plausible payment or credit remains unchecked. The reconciliation should record date and outcome. For “correct, resend and set a deadline”, the workflow should continue only after ownership, deadline and the exception route are clearly set in the system.
The rule should not exist only in a manual. The system should define a trigger, case owner, deadline and escalation path, making it clear why the case was processed, paused or transferred. For “correct, resend and set a deadline”, quality control should reconcile the balance and underlying entries once more against the original evidence.
Use structured invoice data as 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 “correct, resend and set a deadline”, this control determines whether the standard workflow applies or an individual review is required.
For larger portfolios, apply the rule consistently while allowing justified exceptions. Defined thresholds, a documented exception route and sample controls help prevent automation from producing factually incorrect measures. The outcome for “correct, resend and set a deadline” should record the current balance, next date, reason for the decision and responsible person. When an invoice remains unpaid, the amount, due date and receipt should be verified before any escalation.
Communicate firmly and customer-focused
Effective payment communication is factual, specific and free from unnecessary pressure. It states the invoice, balance, due date, payment method, contact and clear deadline. It also provides a channel for documented objections and genuine payment difficulties. Courtesy does not mean allowing deadlines to pass without consequence; consistency does not mean threats or public shaming. A uniform tone and a single contact are more likely to preserve the commercial relationship than changing and contradictory messages. For “correct, resend and set a deadline”, quality control should reconcile the balance and underlying entries once more against the original evidence.
A common mistake is to infer default directly from an open balance. Corrections, counter-rights and receipt issues must be checked first, and calculations should allow a third party to reconstruct every amount and period. For the specific issue “correct, resend and set a deadline”, this requirement should be recorded in the review note with its date and supporting evidence.
Validate the claim before escalation
Before any reminder or handover, the creditor should reconcile the creditor and debtor identities, contract, performance, invoice amount, due date, payments, credit notes and objections. The company name and legal form must match the actual contracting party. For ongoing contracts, termination, term and billing period must be checked. Only the balance remaining after all payments and credits may be pursued. A short internal approval step prevents non-existent claims, duplicate handling and unnecessary costs. The outcome for “correct, resend and set a deadline” should record the current balance, next date, reason for the decision and responsible person.
The article therefore leads to a reviewable decision rather than a blanket measure. Once the claim and evidence are clear, Fortis Inkasso GmbH & Co. KG can take the next out-of-court step; objections should first be assessed legally. For “correct, resend and set a deadline”, the workflow should continue only after ownership, deadline and the exception route are clearly set in the system.
