Net 30 is not a payment term. It is a hope.
You wrote "Net 30" on the invoice because that is what everyone writes. The client read it as "Net whenever." In international B2B trade, the average actual payment time is 58 days — nearly double the stated terms. You are running an interest-free lending operation and calling it accounts receivable.
The problem is not that your clients are dishonest. The problem is that your terms have no consequences and your contracts have no teeth.
What Net 30 actually means by country
In Germany, B2B invoices are paid in an average of 43 days. In the Netherlands, 39. These are countries where commercial culture, court efficiency, and enforcement mechanisms align to make late payment uncomfortable.
In Italy, the average stretches to 68 days. In Spain, 72. In Brazil, 84. In these jurisdictions, late payment is structural — embedded in commercial practice so deeply that your Net 30 terms are interpreted as a suggestion, not an obligation.
Your payment terms are a contract clause. The debtor's jurisdiction determines whether that clause has weight. If you sell to Italian and Brazilian clients on the same terms you use for German clients, you are applying a uniform policy to a non-uniform reality. The result is predictable.
The interest you are not charging
EU Directive 2011/7/EU on combating late payment in commercial transactions entitles you to charge interest at a minimum of 8 percentage points above the ECB reference rate on every day a B2B invoice is overdue. On top of that, a flat €40 minimum compensation per invoice for recovery costs.
On a €50,000 invoice paid 60 days late, the statutory interest alone is approximately €700. Over a portfolio of twenty overdue invoices, you are forfeiting €10,000 to €15,000 per year in interest you are legally entitled to collect.
Most companies do not charge this interest. The reasons are always the same: they do not want to damage the relationship, they do not think the client will accept it, they worry about losing future business. The debtor knows all of this. It is why your invoice is at the bottom of the payment pile.
Charging statutory interest is not aggressive. It is a signal that your terms are terms, not decoration.
Three structures that actually work
Retention of title. If the buyer does not pay, the goods remain your property. This clause — Eigentumsvorbehalt in Germany, réserve de propriété in France, riserva di proprietà in Italy — is enforceable across the EU and in most common-law jurisdictions when properly drafted. It transforms your position from unsecured creditor to secured owner. This single clause has prevented more bad debt than every reminder email ever sent.
Milestone payments. Standard in construction and consulting, underused in manufacturing and services. 30% on order, 40% on delivery, 30% on acceptance. The client's total exposure at any point is limited, and yours is limited to the last milestone. If they stop paying at milestone two, you stop delivering. The conversation is short.
Credit limits with review triggers. Every new international client starts with a conservative credit limit — €10,000 or equivalent — and the limit increases only after three consecutive on-time payments. A client who pays late on the initial tranche never reaches the amount that would hurt you. The system self-selects for reliability.
The clause worth more than your payment terms
If you change one thing after reading this article, add a retention of title clause to your standard terms of sale. It costs nothing to include and transforms your legal position in a default.
Without it, you are an unsecured creditor. In insolvency, you queue behind banks, employees, and tax authorities. With it, you have a claim against specific goods — goods the administrator cannot distribute to other creditors because they were never the debtor's property.
The clause must be drafted for the debtor's jurisdiction. A German Eigentumsvorbehalt has specific registration requirements that differ from a French réserve de propriété. A clause drafted in English common-law style may not survive in a civil-law court. Your commercial lawyer — or your collection partner — can tell you whether your current terms hold up in the jurisdictions where you sell.
If the answer is no, the next invoice you send is an unsecured loan at 0% interest to a borrower whose creditworthiness you have not checked. That is not a payment term. That is a bet.
