A whole-turnover credit insurance policy is not paid for on an amount fixed in advance: it is paid for on what the insured declares it has sold, period after period, and that declaration is the one point in the contract where the insurer depends entirely on the insured's good faith. It is also the point finance departments treat as an administrative formality, entrusted to a team that does not know what turns on it. Yet the sanction for an inaccurate declaration is almost never a premium adjustment: it is a reduction, or a loss, of the indemnity, and the gap between the two runs into hundreds of thousands of euros.
The mechanism is simple to describe and is better understood backwards. The contract fixes a rate applied to insurable turnover; the insured periodically declares that turnover, monthly or quarterly; the insurer calls a provisional premium and adjusts at year end on the actual declarations. While all goes well, this chain is pure accounting mechanics. It becomes decisive at the loss, because the insurer then checks that the claimed receivable did appear in a declaration: an undeclared receivable is a receivable whose premium was not paid, and the insurer maintains it was not covered.
Two ways of declaring badly coexist and do not have remotely the same consequences, which is often unknown. Under-declaration in amount, on properly registered buyers, ordinarily calls for a proportional rule: the indemnity is reduced in the ratio of what was declared to what should have been. Omitting an entire buyer, by contrast, is not corrected pro rata: deliveries to a buyer never declared were never submitted to the insurer, it was never able to grant or refuse a limit on it, and the loss is not reduced, it is outside cover. The first error costs a fraction, the second costs everything.
One must gauge how easily the second happens in a company acting in good faith. A new buyer is opened by a salesperson, the first delivery leaves, the declaration is made by an accounting team on the basis of a scope configured the previous year, and the new name does not appear in it. A recently acquired subsidiary invoices on its own system, outside the file feeding the declaration. An exceptional sale is booked to an account different from ordinary sales. In all three cases nobody concealed anything, and yet the buyer in question does not exist for the insurer. That is why the useful check is not on amounts but on the list of names.
A second misunderstanding concerns the meaning of the word insurable. The turnover to be declared is not total turnover, nor is it the turnover the insured considers risky: it is the one the policy defines, with its exclusions of countries, sectors, sales between companies of one group, and sometimes a floor below which receivables are not declared. Declaring too much is a pointless cost, declaring too little opens the proportional rule, and the only way to settle it is to read the definition rather than reconstruct it by reasoning.
A third and subtler point concerns the good-faith decline. A difficult year naturally leads to declaring less, and that decline is perfectly legitimate where it reflects genuinely lower sales. It becomes a problem where it results from a shift in scope rather than a fall in activity, for instance where part of the turnover has migrated to an entity or a channel that no longer feeds the declaration. Seen from the insurer, the curve is the same in both cases, and the distinction only emerges at the loss. An insured observing a marked decline has an interest in writing down its reason itself, because that is the only moment when the explanation is credible without being defensive.
The discipline therefore comes down to three annual checks that cost almost nothing. Reconcile the list of declared buyers with the list of invoiced buyers, not the amounts, because it is the omission of a name that costs everything. Reread the definition of insurable turnover after any organizational change, acquisition, new subsidiary, new channel. And document any significant variation at the moment it occurs. Those three steps belong to the team producing the declaration, and that team must know that it is not filling in a billing form but determining the extent of the cover.
An exporter insured under a whole-turnover policy declares its insurable turnover quarterly. Year N-1 was declared at 31 million euros; year N is declared at 24 million, the finance department observing in good faith a harder market. In fact, 5 of the 7 million difference corresponds to sales of a subsidiary acquired in March, which invoices on its own system and does not feed the declaration file. In November, a 1.4 million loss occurs on a buyer of that subsidiary, never declared, on which no limit was ever requested. A second loss, of 600,000 euros, occurs on a long-standing buyer properly registered but whose deliveries for the year were declared at half their value. What happens on each?
The two losses do not arise from the same mechanism, and treating them together would mean negotiating the wrong thing. On the subsidiary's buyer, there is nothing to reduce: it was never declared, no limit was ever requested or granted on it, and the insurer therefore never had the chance to accept or refuse it. This is not under-declaration, it is a receivable outside cover, and the 1.4 million is lost in full. The finance department's good faith is real and without effect: nobody concealed anything, and yet that buyer does not exist for the insurer. On the long-standing buyer, the position is quite different, because the name was registered and the limit granted: the declaration bears on amount, the proportional rule applies, and the indemnity is reduced in the ratio of declared to due, that is roughly half of the 600,000 euros. What is at stake now is the rest of the year and the next one. The reconciliation to run is not of amounts but of names: the list of invoiced buyers, subsidiary included, against the list of declared buyers. And the fall from 31 to 24 million, had it been explained in writing when it occurred, would have been an explanation; put forward after two losses, it will be read as a defence.
- 01The turnover declaration is the one point in the contract where the insurer depends entirely on the insured's good faith, and it decides the extent of the cover.
- 02Under-declaring an amount on a registered buyer opens a proportional rule; omitting an entire buyer puts the receivable outside cover.
- 03Omission happens in companies acting in good faith: a new customer, an acquired subsidiary, a separate invoicing channel, a scope configured the year before.
- 04Insurable turnover is what the policy defines, neither the total nor what the insured deems risky: the definition is read, not reconstructed.
- 05The useful check is on the list of names, not on amounts, and a marked decline is explained in writing when it happens.
