4.1. All invoices are payable in cash in euros. After delivery, MBSS sends the Customer an invoice, which must be paid in full and within fourteen (14) calendar days of the invoice date. Recurring services are invoiced periodically, in principle monthly, quarterly or annually depending on the chosen subscription. MBSS remains entitled to send interim invoices according to the progress of the services, and may suspend the start-up and delivery of its services until after payment, without prejudice to other rights.
4.2. Any debt that remains wholly or partially unpaid on the due date shall automatically and without notice of default bear interest of 12% per year from the due date until the day of payment, as well as a fixed compensation of 10% on the outstanding principal with a minimum of 125 euros per principal, without prejudice to the right to prove and claim higher damages and the right to compensation for legal and enforcement costs.
4.3. If a due debt remains wholly or partially unpaid, all of the Customer's debts not yet due become immediately payable. Payments made after the due date are first credited against interest, the penalty clause, legal costs and enforcement costs, and only thereafter against the principal.
4.4. The Parties mutually declare that these compensations do not create an imbalance, are not disproportionate to the harm that may be suffered by the other Party, and do not exceed the damage they could foresee at the start of the Agreement in the event of default.
4.5. In the event of non-payment of a single invoice on its due date, MBSS has the right to immediately and without notice of default stop all further deliveries; all invoices not yet due become immediately payable. Moreover, MBSS has the right in such circumstances to announce that it considers all ongoing contracts to be dissolved.
4.6. If, between the order date and the delivery date, a price increase occurs as a result of an exchange rate change or a change in any tax or levy, MBSS may always pass this on. In the event of a price increase, the Customer may withdraw from the purchase at the latest on the delivery date, subject to payment of a fixed compensation of 25% of the agreed price.
4.7. MBSS's prices may be revised according to the evolution of material prices, transport prices and rising labour costs, between the moment the order confirmation is signed and the moment of delivery. This is done on the basis of the price revision formula P = p {a + b (S/s) + c (I/i)}.
- P = the new price; p = the original price provided for in the order confirmation.
- a = the percentage of the price not subject to revision (a ≥ 0.20).
- b = the percentage of labour costs in the total price; S = the new wage index (the month preceding delivery); s = the original wage index (the month preceding the Agreement).
- c = the percentage of material costs in the total price; I = the new material index; i = the original material index.
- a + b + c = 1.
