Nexx360 provides a Service enabling its Clients (publishers, advertising agencies, e-commerce or other sites) to optimise revenue opportunities from their visitor traffic and their advertising space, either by increasing the competitive bidding of the different market players, or by displaying monetizable formats in spaces that may be under-valued or have even remained unused.

Clients will have a dashboard on the platform which, depending on their subscribed service level, lets them view the real-time performance of the Service, the number of requests passing through and more generally, the monthly cost for the service provided. This data may expand as the platform’s technical developments increase.

Advertising revenues generated through the services will be settled directly by the Intermediaries. Nexx360 is a third party to the existing contractual relationships between the Intermediaries and its Clients.  


In order to use the Service, Clients must first create an account on the website,, provide certain information relating to their identity and their company and accept these T&Cs.


3.1 Service fee

The Service is invoiced at the price of 0.03 euro cents per ‘called placement.’

As a Client, you may check the number of requests which have passed through the Service at any time on your dashboard, and suspend the Service, if you wish.

3.2       Payment terms for the Services

At the end of the month, Nexx360 sends its Clients an invoice for the requests which have passed through its Service.

Nexx360’s invoices are payable on receipt.
Failure to pay the sums due within thirty (30) days shall automatically result in monthly interest of 5 basis points above the legal interest rate being applied without prior notice. 

Any sum that is unpaid on the due date shall in addition be automatically subject to a lump sum compensation of 40 euros for debt collection costs. 

In accordance with Article L 441-6 of the French Commercial Code, when the collection costs incurred are higher than this lump sum compensation, Nexx 360 may ask a debtor Client to pay an additional compensation, after providing substantiating documents.


4 1. On the initiative of Nexx360

In the event of non-payment, Nexx360 reserves the right to suspend access to the Platform until the sums due are settled, or terminate the agreement.

In general, if a Client is in breach of the obligations contained in these T&Cs, Nexx360 reserves the right to suspend or delete, automatically and without any legal formality, the associated accounts, after formal notice sent by post or email remained unheeded for a period of eight (8) calendar days following its receipt.

Any discussion between Intermediaries and Clients falls under their sole liability and Nexx360 accepts no liability in that respect. In particular, as Nexx 360 is a third party to the contractual relationships between the Intermediaries and its Clients, it may not be held liable for any failure of an Intermediary to pay the advertising revenues owed to the Clients and/or for the Clients’ failure to pay any amount owed to the Intermediary.

Article 9– Miscellaneous provisions

If any of the clauses of these T&Cs is declared invalid, this shall not result in the other clauses of these T&Cs becoming invalid, which shall remain in full force and effect between the parties.

The fact that Nexx 360 does not at any time invoke any of the clauses of this Agreement and/or a breach by the User of any of their obligations under the T&Cs, may not be interpreted as Nexx 360 waiving its right to subsequently invoke any one of such contractual clauses or obligations.

Accordingly, no special terms and conditions may prevail over these T&Cs, unless expressly accepted in writing by Nexx 360. Any contrary term invoked by a User shall therefore not be enforceable against Nexx 360 unless expressly accepted, regardless of the moment when it was brought to its attention.

Article 10 – Applicable law/disputes

These Terms and Conditions of Sale are governed by French law.

Any dispute relating to the existence, validity, interpretation or termination of the agreement entered into between Nexx 360 and its Clients shall be subject to the exclusive jurisdiction of the Commercial Court in the place where Nexx 360 has its registered office, notwithstanding multiple defendants, the introduction of third parties or summary proceedings.
