Open receivables documented in GoBD-compliant form: how to keep changes and records traceable

The technical question is when a claim becomes enforceable and which ancillary claims arise. The basis is the due date, default and the contractual agreement, supplemented by the statutory rules on default interest and recovery costs.

From the onset of default, interest can be charged: five percentage points above the base rate against consumers, nine percentage points where no consumer is involved. In business-to-business trade a flat fee of EUR 40 may also apply. A well-maintained open items list is the basis for every DSO and ageing analysis. What counts is less the perfect solution than one that is actually applied day to day.

Three requirements have to come together: a validly arisen claim, its maturity and the debtor's default. If one of these stages is missing, interest and costs are not enforceable even where the principal amount is undisputed.

The debtor also has to be identified unambiguously: correct company name, legal form and address. Mix-ups cause delays in the dunning procedure. A monthly look at the age structure reveals shifts earlier than any individual case review. For the constellation set out here the rule is: how to keep changes and records traceable.

Interest is calculated to the day from the onset of default on the outstanding amount. The applicable base rate plus the statutory margin is decisive. Where default runs past an adjustment date, the period is calculated in sections.

The documentation belongs in the case file, not in a separate spreadsheet. Otherwise it cannot be found when the case moves to collection or court. Positions with no movement for several months belong on a separate review list. That keeps the case understandable for colleagues with no prior knowledge of it.

The most common mistake is waiting. Reacting only after months costs information, contacts and, in an insolvency, part of the dividend. Equally critical are vague deadlines such as "immediately", missing proof that the invoice was received, and reminders without an itemised breakdown. A short note in the system replaces any later reconstruction from memory.

Equally critical: receivables left unmentioned out of consideration for the customer relationship. The amount does not disappear, but the default risk rises. An open items list should show invoice number, due date, remaining balance, dunning level and last contact for every position.

For creditors this means liquidity becomes more predictable once the consequences of default are asserted consistently. Ancillary claims are less a source of income than a signal that payment terms are meant seriously.

At the same time the documentation effort grows. Automating it pays off; handling it manually erodes the benefit quickly. Open receivables are reconciled with bank transactions monthly so that phantom balances never reach a reminder letter. The earlier this point is clarified, the less time enforcement costs later.
