Reviewed: 2026-07-26. This article, “Invoice is not paid without a written contract: which records count”, 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. A contract may exist without a signature, but its terms and price need other evidence. A documented workflow protects liquidity, evidence and the customer relationship. The information is general and does not replace a review of the individual case.

Prove a claim without a signed contract

A claim does not automatically fail because no signed contract exists. Depending on the transaction, formation and terms may be shown by offer and acceptance, purchase orders, emails, chat messages, delivery, use, partial payment or other conduct. Proving price, scope, term and extras may be more difficult. Contemporaneous documents should be preserved chronologically and inconsistencies identified openly. For a high-value or seriously disputed claim, a legal evidence review is advisable before court action. For the specific issue “which records count”, this requirement should be recorded in the review note with its date and supporting evidence.

For “which records count”, 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 “which records count”, this control determines whether the standard workflow applies or an individual review is required.

Documents for a reliable receivables file

The minimum file should contain the contract or order, invoice, evidence of delivery or performance, agreed payment terms, correspondence, reminder, bank or customer ledger, credit notes and objections. Depending on the case, acceptance records, time sheets, shipping data, termination notices, terms and security may be needed. Documents should be named chronologically and stored without alteration. A short factual summary identifying unresolved points reduces queries and prevents inconsistent information from reaching the debtor, collection provider or court. For “which records count”, 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 “which records count”, quality control should reconcile the balance and underlying entries once more against the original evidence.

Resolve a disputed claim systematically

If the customer disputes performance, scope, quality or price, another standard reminder will not resolve the issue. The file needs the contract or order, specification, acceptance, delivery evidence, time records, correspondence, variations and a specific response to each objection. Undisputed and disputed amounts should be separated. Debt collection can structure the out-of-court exchange; where a substantial legal or factual dispute remains, the creditor should assess whether an ordinary court action is more suitable than the gerichtliches Mahnverfahren (German court payment-order procedure). In “which records count”, 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 “which records count” 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.

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. For “which records count”, 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 “which records count”, this requirement should be recorded in the review note with its date and supporting evidence.

Choose between collection, payment-order proceedings and litigation

Out-of-court debt collection is useful where communication, a payment arrangement or structured clarification may still work. The gerichtliches Mahnverfahren (German court payment-order procedure) is efficient for a quantified monetary claim that is likely to remain uncontested. Ordinary litigation is usually more suitable where the contract, performance, defects, set-off or amount is seriously disputed. The decision depends not only on costs but also on evidence, jurisdiction, limitation, enforceability and the debtor’s economic position. It should be documented before any deadline expires. The outcome for “which records count” 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 “which records count”, the workflow should continue only after ownership, deadline and the exception route are clearly set in the system.
