"Article 21. Payment of the invoice. The due date of the invoice shall be as agreed by the parties. If no mutual agreement is reached, the due date of the invoice shall be the fourth working day after its delivery, provided that the invoice is issued after the procedure established in the previous articles of this chapter has been exhausted.

The trader or the unregulated user shall use the payment procedures indicated by the respective market participant and provide via fax, mail or electronic means, the complete information of the payment made, at the latest on the working day following the payment date. 
If the payment is not made within the stipulated period, the marketer or the unregulated user shall be in breach of its obligations and the respective market participant may execute the coverage mechanisms agreed with the marketer or the unregulated user. When these coverage mechanisms are not sufficient to pay the obligations of the services provided in the natural gas market, the respective market participant may charge the default interest rate on the missing amounts.
The marketer or the non-regulated user shall pay, within the term of the invoice issued pursuant to Article 18 of this Resolution, the amounts that are not objected or, otherwise, the respective market participant may make effective the coverage mechanisms agreed with the marketer or the non-regulated user up to the value corresponding to the amounts that are not objected.
Once the market participant that provided the service resolves the difference that motivates the objection, and if there are missing values, the trader or the non-regulated user shall pay them recognizing the default interest rate if the objection is not accepted. Otherwise, the DTF in force at the time the invoice issued according to Article 18 of this Resolution is due.
Payments made by marketers and unregulated users will be applied first to the cancellation of interest on arrears and then to the capital value, considering the age of the due dates, in accordance with Article 881 of the Commercial Code.
Paragraph 1. The delay in the issuance of the invoice by a market participant shall not affect the validity or values of the coverage mechanisms for payment of supply, transport or distribution presented by the marketer or unregulated user to the corresponding market participant.

In any case, at the time of the subscription of the corresponding contract, the non-regulated user may take advantage of the term established in this article for the marketer that serves regulated users".
It should be noted that the modifications made at the due date of invoices should not result in increases in the costs of providing services for the attention of regulated users and non-regulated users who are served through a marketer”.
