From now on, you can rely on the IOS procedure for undisputed invoices between companies. A bailiff personally visits your customer and means an official reminder to pay. The emphasis is on mediation and the creditworthiness of your customer is taken into account to maximize recovery opportunities.
Your customer must then pay the overdue amounts in one go or agree on a payment plan. If he does not respond or does not comply with his payment arrangement, the judicial officer can request an enforceable title after one month and 8 days and force the defaulter to pay with all judicial means of pressure.
