The SUPPLIER will not be held responsible for the consequences of a wrong estimation of the remaining level or the volume available in the container concerned. This exclusion concerns, in particular, the consequences related to a tank overflow during a delivery or to a break in the availability of the CONTENTS.

For purchases in France, the prices are indicated in euros, all taxes included. They take into account the VAT applicable on the day of the order of an amount of 20%. Any change in the applicable rate may be reflected in the selling price of the Products.

They do not include shipping costs which appear on the order summary screen.

Products with a subscription solution will require a subscription. The amount of this subscription will be proposed including VAT at 20%.

For purchases abroad, the quotations may be indicated in euros, excluding taxes. This distinction will be clearly specified on the relevant quotation.


9.1. Payment of “Products

Upon signature of the quotation, the Customer is obliged to proceed, if necessary, to the payment of the deposit mentioned in the quotation concerned.

Payment of the balance of the Price is due within thirty (30) days of the invoice number, once the Products have been delivered.

9.2.b Successive payment

Once the term of the initial subscription period has expired, access to the Platforms is payable in arrears for the following year on each anniversary date. The minimum subscription period is 12 months.

Amounts due under the Contract are invoiced in arrears. The payment term is set at thirty (30) days from the date of issue of the invoice by the Provider.

  1. right of withdrawal & cancellation

10.1. Termination at term

Your subscription to FUEL IT is concluded for an initial fixed period of time as specified in the quote.

Upon expiration of the initial term and successive commitment periods, the subscription to the “Platforms” is tacitly renewed for a new period of 12 months, unless one of the Parties has requested its express termination by registered letter with acknowledgment of receipt at least two (2) months before the expiration date.

The Customer is aware that the economic model of THE FOURDATA COMPANY implies that only the subscription for a duration of 36 months allows to reach a remuneration equivalent to the initial price of the FUEL IT and the included services. As such, at the end of the 36-month contract, the Customer may terminate his subscription without paying any additional fees. In this particular case, the Customer will have access to the FUEL IT service, but will no longer benefit from the maintenance service.

However, if the Customer does not wish to be committed for such a long period, THE FOUR FACTOR COMPANY offers shorter subscription periods of 12 or 24 months. In order to compensate for the losses incurred by THE FOUR FACTOR COMPANY at the end of contracts of less than 36 months, a deblocking fee will be charged to the Client who does not wish to renew his subscription and who wishes to continue to use FUEL IT without a subscription. Thus:

– If the termination takes place at the end of the 12 months, the Customer will be charged a €90 FUEL IT unblocking fee, so that the Customer can continue to obtain the data collected in the mobile application. The maintenance service will therefore be excluded.

– If the termination takes place at the end of the 24 month subscription, the Customer will be charged a €45 FUEL IT unlocking fee so that the Customer can continue to obtain the data collected in the mobile application. The maintenance service will therefore be excluded.

If the Client does not wish to continue using the FUEL IT sensor at the end of the 12, 24 or 36 month subscription, no compensation will be claimed from the Client.

10.2. Early termination

If the Customer wishes to terminate his contract before its term, he will be required to pay all the remaining monthly instalments as compensation for the damage suffered by THE FOURDATA COMPANY.

Also, in the event that the Client wishes to continue to use the FUEL IT and therefore to have access to the data, he will be required, in addition to the predefined compensation, to pay the unblocking fees corresponding to the duration of the subscription, as indicated above.

In accordance with the legal provisions in force, the Customer has a period of fourteen (14) days from receipt of the Product to exercise his right of withdrawal from the Seller, without having to justify his reasons or pay any penalty, for the purpose of exchange or reimbursement, provided that the Products are returned in their original packaging and in perfect condition within fourteen (14) days following notification to the Seller of the Customer’s decision to withdraw.

Returns must be made in their original condition and complete (packaging, accessories, instructions …) accompanied by the purchase invoice. Damaged, soiled or incomplete products are not accepted.

  • Or by a letter to the Seller informing him of his desire to exercise his right of withdrawal. (See model on the Site)
