Terms of Use
& Terms of Sale

These general terms govern the use (Part A — Terms of Use) and the sale (Part B — Terms of Sale) of all products and services offered by Frédéric KULAS Sole Proprietor known as KLS-Concept ("the Publisher"), located at 4 chemin du binai, 61300 Crulai (France).

The Customer acknowledges having read these terms and agrees to comply with them. These terms apply without restriction to all commercial transactions concluded on the websites managed by KLS-Concept or by quotation.

The acquisition of goods or a service via www.kls-concept.com, www.gse-web.online or www.gse-web.xlexe.com implies unconditional acceptance of these terms.

These terms shall prevail over any other general or specific terms not expressly approved by KLS-Concept.

Catalogues, brochures and other commercial or technical documents, excluding these general terms, cannot in any case be considered as contractual.

All data provided and the recorded confirmation shall serve as proof of the transaction. The confirmation shall constitute signature and acceptance of the transactions carried out.

The Customer is informed that it is their responsibility to read the general terms during each visit to the websites and that the validation of each order necessarily implies acceptance of the general terms.

The Customer has the option to save or print these general terms.

Confirmation of the order or quotation and the validation by "click" of due reading of these terms entails acceptance of these general terms, recognition of having perfect knowledge of them and waiver of the right to rely on their own purchasing terms or other conditions.

In this document, the following capitalised terms have the meaning given to them below:

The software offered remains the property of the manufacturers. Only one or more user licences have been granted.

The User may not, in any form whatsoever, transfer, license, format, communicate or lend them even free of charge, nor reproduce them except for backup purposes.

The Customer shall maintain, in good condition, the ownership notices on the programs, the user manual and shall ensure the confidentiality of the software.

The Customer shall refrain from modifying, in any way whatsoever, the software and its media. They shall refrain from counterfeiting it, permitting counterfeiting or favouring it.

Using the GSE-Web Services requires the creation of an online account.

The User is responsible for the accuracy of the information they provide and undertakes to update information concerning them or to notify KLS-Concept without delay of any change affecting their situation.

The User takes all useful measures to maintain the confidentiality of access to their account. In case of fraudulent use of their account, the User undertakes to immediately notify KLS-Concept and to change their access password without delay.

KLS-Concept implements appropriate technical and organisational measures to protect the integrity, confidentiality and security of the hosted data, and performs regular backups of the databases. The Customer remains responsible for the accuracy of the data they enter into the Services and for keeping their own exports (Article 8).

Subscribing to the GSE-Web Services constitutes the Customer's commitment to pay the price corresponding to the selected services and to their country of residence.

The prices displayed on the site are exclusive of tax. VAT and any additional charges are applied to the invoice depending on the Customer's country of residence.

The invoicing arrangements, the payment due date and the consequences of late payment (including suspension of access to the Services) are set out in Part B, Articles 15 and 19.

All features described as "unlimited" are understood under normal conditions of use.

The use of the Services resulting from the subscription is strictly personal and cannot be rented, transferred free of charge or for consideration to a third party.

Any use likely to damage, disable, overload the KLS-Concept infrastructure or hinder the enjoyment of the service by other users is prohibited.

In case of non-compliance, KLS-Concept reserves the right to immediately block access and delete all account information without notice and without refund.

The Customer may, at any time, export their business data (products, stock and stock movements) from their administrator account, in a usable format. KLS-Concept thus facilitates the reversibility and recovery of the Customer's data.

The export archive includes business data together with the files and photographs attached to it (product images, attached documents). It is the Customer's responsibility to keep the archive obtained and to check its contents: KLS-Concept cannot be held liable for the loss of data that the Customer has not exported, or whose archive the Customer has not kept.

The archive is made available to the Customer for seven (7) days from the time it is generated, after which it is deleted. The Customer may request a new one at any time, up to one per day.

In the event of subscription end (termination or non-renewal), the Customer's business data is retained for ninety (90) days from the expiry date, to enable the Customer to exercise the export option provided for in this article. At the end of this period, it may be permanently deleted under the conditions set out in the privacy policy and the DPA.

Furthermore, with regard to GSE-Web, the owner of the organisational account may at any time delete their entire database themselves from their account. This deletion is immediate, permanent and irreversible: no data or backup can then be recovered or returned, and KLS-Concept cannot be held liable in this respect.

The Customer may order specific developments or features. Any request of this kind is the subject of a separate quotation and commercial proposal, specifying the scope, the price and the applicable special conditions; these documents prevail, for the development concerned, over these terms.

Unless otherwise agreed in writing, the developments and features produced, including where they are funded by a Customer, remain the exclusive intellectual property of KLS-Concept. KLS-Concept reserves the right to integrate them into its offer and to make them available to its other customers, with or without additional cost, without any exclusivity being claimed by the commissioning Customer.

GSE-Web provides an internal messaging service. This is exclusively reserved for professional exchanges related to the account's activity (tracking of operations, team coordination, processing of orders and stock movements, etc.).

The User is expressly informed that the messages exchanged via this messaging service are in no way private: they may be viewed, retained and processed by KLS-Concept and its developers, in particular for support, maintenance, security and proper operation of the service. Consequently, the User shall refrain from including any sensitive personal data, any confidential or private information, as well as any element unrelated to their professional activity.

Any use for personal purposes is strictly prohibited, as is any unlawful, defamatory, insulting, hateful, discriminatory, harassing content or content contrary to public order and morality. In the event of a breach, KLS-Concept reserves the right to moderate or delete the messages concerned and, where applicable, to suspend or terminate access to the account, without notice or refund and without prejudice to any action.

When hosting the Customer's business data (products, stock, stock movements, the accounts of the Customer's own users, etc.), KLS-Concept acts as a processor within the meaning of article 28 of the GDPR, the Customer remaining the controller of that data.

The databases are hosted in France, with a professional hosting provider established in the European Union. They are backed up daily, and all backups are kept within the European Union. For Customers in a Dedicated Private Cloud, the location of the instance is stated in the technical sheet referred to in article 30.2.

KLS-Concept implements appropriate technical and organisational measures to ensure the security of this data and processes it only on the Customer's instructions, solely for the purposes of the service. At the end of the subscription, the business data can be returned by the Customer using the export function, then deleted under the conditions set out in the privacy policy. A data processing agreement (DPA) detailing these commitments can be consulted on our dedicated page; a signed version, in the Customer's name, is available on request at contact@kls-concept.com.

KLS-Concept will not provide any assistance on the use or installation of the Microsoft Excel software.

KLS-Concept will not provide any assistance and cannot be held responsible in the event of problems if the Customer uses a version other than the one downloaded from their customer area on www.kls-concept.com.

GSE for Excel is free software: its provision does not constitute a sale and does not fall under Part B. Its use is governed by the separate end-user licence agreement (EULA) accessible on its download page, which prevails over these terms for this software.

Support channels

Support is valid immediately after payment and subscribed for an unlimited duration as long as the GSE-Web software is operated by KLS-Concept and the Customer is up to date with their subscription.

Personalised support (ENTREPRISE and CORPORATE plans)

KLS-Concept does not guarantee data recovery if the database has been erased or corrupted. It is the User's responsibility to carry out regular backups.

Support does not in any way guarantee the resolution of the problems encountered.

The User authorises KLS-Concept to use all useful means (Teams, remote desktop, etc.) to help resolve the problem.

The websites www.kls-concept.com, www.gse-web.online and www.gse-web.xlexe.com present the products, plans and services sold with the necessary characteristics enabling the potential Customer to know, before final order, the essential characteristics of the products, plans and services they wish to purchase.

A demo site is available, offering all the main features of the plans.

The Customer must first ensure that the product is suitable for the intended use.

KLS-Concept provides no warranty as to the ability of the hardware, plans or services to achieve what the Customer has set for themselves.

A deposit of 20% of the total amount is required after acceptance of the quotation, before any service is performed. This deposit must be paid by bank transfer or online bank card.

KLS-Concept reserves the right to require payment by bank transfer or bank cheque if the order amount exceeds €500. Furthermore, if the Customer is not clearly identifiable, KLS-Concept may require the sending of a Kbis extract as well as payment by bank or postal transfer.

KLS-Concept reserves the right to refuse to make a delivery or to honour an order from a Customer who has not fully or partially paid for a previous order or with whom a payment dispute is in progress.

For payments by cheque, the equipment is shipped after verification of payment by the financial service.

The prices indicated on the site do not constitute an offer but are given for information purposes. These prices are NET and excluding VAT.

Unless otherwise stated, prices are exclusive of transport costs. Shipping costs may be charged in addition depending on the nature and destination of the order; their amount is then indicated on the quotation or purchase order before validation. Prices may be modified without notice until the date of receipt of the order together with payment.

In the event of a pricing error, the Customer will be notified by phone or email of the possibility of cancelling their order.

NB: The delivery price never includes any customs duties payable outside metropolitan France and the EU.

The majority of products are in stock and can be delivered quickly. However, delivery times are not contractual.

No refund, even partial, may be claimed following a delay that is not attributable to gross or intentional misconduct by KLS-Concept, or to a case of force majeure.

In the event of stock-out or a delay of more than two weeks, the Customer will be contacted very quickly by phone or email and may, if desired, cancel their order.

The online sale of hardware products is reserved for buyers residing in France or Monaco and for deliveries required in these geographical areas. For any order outside France, a quotation must be drawn up before any purchase.

Deliveries are made to the address indicated on the purchase order. It is the Customer's responsibility to verify the accuracy of the delivery address.

The risks are borne by the Customer from the moment the products have left the KLS-Concept premises.

In case of delivery error and/or non-conformity in nature or quality of the products compared to the indications on the purchase order, the Customer must issue a reasoned complaint to KLS-Concept within 48 working hours of receipt of the delivery.

The goods sold remain the property of the seller until full payment of their price in principal and interest.

However, the transfer of risk taking place at the time of pick-up of the delivery, the Customer shall, if necessary, turn to the carrier in the event of an anomaly.

In addition, the Customer undertakes to take all necessary care for the custody and conservation of the products as well as to take out any useful insurance.

The Customer also undertakes not to resell the goods concerned before their full payment.

Finally, the Customer undertakes to immediately notify of any seizure that may be made on behalf of a third party.

Unless otherwise agreed in writing by the Publisher before subscription, invoices are payable within thirty (30) days of the invoice date. Any request for different payment terms must be the subject of the prior written agreement of the Publisher; failing a written agreement, the payment conditions provided for in these terms remain applicable.

Any late payment shall automatically give rise, without any reminder or formal notice being required, to late-payment penalties calculated at three times the legal interest rate, from the day following the due date shown on the invoice.

In accordance with Article L. 441-10 of the French Commercial Code, a fixed indemnity of €40 for recovery costs shall also be due for each invoice paid late. Where the recovery costs incurred exceed this indemnity, KLS-Concept reserves the right to claim additional compensation upon presentation of supporting documents.

In the event of partial payment, the sums paid shall be applied first to recovery costs, then to late-payment penalties and then to the oldest claims.

As long as the sums due have not been paid in full, KLS-Concept may suspend the performance of ongoing services or refuse any new order.

In the event of non-payment when due, the Publisher reserves the right, after a formal notice that has remained without effect for a period of eight (8) days, to suspend all or part of the access to the Services until full payment of the sums due, without this suspension giving rise to any compensation or to the postponement of the subscription due date. The Publisher may also, by right and without judicial formality, rescind the sale and require the return of the products delivered under the retention of title, without prejudice to any damages.

In the event of suspension of the service for non-payment, the Customer's data is retained for ninety (90) days from the date of suspension. At the end of this period, and in the absence of full settlement, it may be permanently deleted, without the Publisher's liability being engaged. The retention and deletion arrangements are detailed in the privacy policy and the DPA.

Consumables are not covered by the warranty. KLS-Concept cannot be held responsible for any consequences on operations, persons or loss of data. The Customer shall ensure that the necessary backups are made.

We cannot be held responsible for the repair times allotted by manufacturers in the context of a warranty return and no substitute equipment will be lent during this period of immobilisation.

For equipment out of warranty, a repair quote will be offered to the Customer.

The repair will be carried out after full payment of the quote. Shipping costs remain the responsibility of the Customer (except for defect upon unpacking in metropolitan France).

The product must not have been used and must retain its new appearance. It must be returned, within 5 days, in its original packaging together with all its accessories and manuals.

The return number (RMAT) must appear clearly on the parcel.

In the event of return without prior agreement or in the event of a dispute, the Customer may retrieve the item at their own expense.

A contribution to administrative and handling fees of 30% with a minimum of €15 excl. VAT will be invoiced in the event of a buy-back due to an order error.

NB: No buy-back on specific orders (products usually not stocked).

The contractual warranty shall be cancelled in the event of opening of the equipment concerned, in the event of use in abnormal conditions (drop, humidity, dust, heat, cold, voltage error, mishandling, risk environment, unlicensed software or software indicated as incompatible) or in the event of electrical problems on the customer's network.

The Customer undertakes to ensure the conformity of their electrical connections and to always interpose a system against lightning and surges.

In the case of a refused warranty repair, the Customer will receive a quote for the shipping costs for the return. In the absence of a response after a period of 12 months, the equipment will be destroyed or will remain the property of KLS-Concept.

The warranty automatically ceases if the Customer has not fulfilled their contractual payment obligations.

In case of non-conformity of the ordered items, the Customer must notify KLS-Concept within three days of receipt of the order.

No return or cancellation will be accepted on an order of products adapted to the Customer's needs.

Returns will only be accepted after prior written agreement from customer service. The Customer must return the products carriage paid, with tracking, in their original packaging, together with the invoice and the return number (RMAT).

In the event of return, the Customer benefits from a credit note (excluding shipping costs) provided that the products are intact. A retention of 20% minimum will be applied for reconditioning. Validity of credit notes: 6 months.

This Contract is concluded for an indefinite period.

It may be terminated at any time by the Customer from their personal account.

In the event of termination by the Customer, the sums paid for the current subscription period remain due to KLS-Concept; termination takes effect at the end of the period already paid for, without any pro-rata refund.

For subscriptions in a Dedicated Private Cloud (CORPORATE plan), the subscription period is annual and is tacitly renewed for successive twelve (12)-month periods. A Customer who does not wish to renew shall notify KLS-Concept in writing of the termination with two (2) months' notice before the end of the current subscription year; failing this, the subscription is renewed for a further twelve (12)-month period. Termination takes effect at the end of the current subscription year and gives rise to no refund of amounts paid for that period, subject to the case of refusal of a price revision provided for in article 16.

In the event of non-compliance by the Customer or the User with these general terms, the privacy policies of KLS-Concept or any applicable legal or regulatory provision or provision resulting from an applicable international convention, KLS-Concept reserves the right to terminate the Contract without notice.

The liability of the parties may not be invoked if the non-performance or delay in performing one of its obligations results from a case of force majeure.

Force majeure means any external, irresistible and unforeseeable event preventing one of the parties from performing its obligations or making the performance of these excessively burdensome, according to the interpretation by case law of French jurisdictions.

The following shall expressly be considered as cases of force majeure:

The Customer shall notify KLS-Concept of the occurrence of any case of force majeure by registered letter with acknowledgement of receipt. Given the very nature of a force majeure event, which may affect its own means of communication, KLS-Concept shall for its part inform the Customer by any appropriate means (in particular by email or by publication on its websites).

KLS-Concept is bound by an obligation of means and exercises reasonable diligence to ensure the accessibility and proper functioning of the service. However, KLS-Concept makes no service-level commitment (SLA) and no guaranteed availability rate: the service may be temporarily suspended for maintenance, updates, technical incident or force majeure, without its liability being engaged on that account.

Any compensation due by KLS-Concept may not exceed the price paid by the Customer in consideration of the Service(s) at the origin of said liability.

In no event does KLS-Concept guarantee the Customer the expected economic, image or information benefits.

KLS-Concept cannot be held responsible in the following cases:

• •Damage caused by the introduction of a virus, by any means whatsoever
• •Financial consequences linked to incorrect handling of software
• •Design defect (or bug) of sold software

The Contract is governed solely by French law.

Any dispute between the Parties arising from the validity, interpretation and/or execution, termination, breach of the Contract shall be submitted by the most diligent Party to the Commercial Court of Alençon, including in the event of summary proceedings, warranty appeal and/or multiple defendants.
