Article 1 – General

1.1 These General Terms and Conditions (hereinafter: Terms and Conditions) apply to all offers, orders and/or agreements between DATAMAISTER and the Client intended for the provision of services by DATAMAISTER . Any deviations from or changes to these Terms and Conditions must be confirmed in writing by DATAMAISTER and will only apply to the relevant offer/order/agreement.

1.2 “Client” is understood to mean any natural person or legal entity for whom or which DATAMAISTER performs services, including their agents, authorized representatives, legal successors and heirs.

1.3 Any general terms and conditions applied by the Client are nonbinding on DATAMAISTER , unless DATAMAISTER has agreed to them in writing.

1.4 If DATAMAISTER has agreed in writing to the applicability of one or more deviating terms and conditions, these Terms and Conditions will remain in full force in all other respects.

1.5 In addition to the Terms and Conditions, special terms and conditions may be agreed between DATAMAISTER and the Client with a view to the performance of the agreement. In the event of inconsistencies between these Terms and Conditions and any special terms and conditions, the special terms and conditions will prevail and these Terms and Conditions will apply additionally.


Article 2 – Agreements and Changes

2.1 An order placed by the Client will be considered by DATAMAISTER to be an irrevocable offer.

2.2 DATAMAISTER is only bound by an order placed with DATAMAISTER vis-à-vis the Client if and as soon as DATAMAISTER has confirmed such order in writing within 3 working days of receipt of the order, or if DATAMAISTER has commenced performing such order. DATAMAISTER explicitly reserves the right to further determine the commencement date upon said confirmation. The invoice for work for which no order confirmation is sent in connection with the nature and/or scale of the work will also constitute an order confirmation, which will be deemed to reflect the agreement accurately and in full.

2.3 The Client shall notify DATAMAISTER in a timely fashion and in writing of any changes that the Client, after having placed an order, may desire in the performance thereof and such changes are only binding on DATAMAISTER if DATAMAISTER has confirmed these arrangements/undertakings in writing. The Client will bear the risk of – correct or incorrect – performance of any orders given verbally or by telephone and/or changes in the performance thereof.

2.4 Any changes to an order placed by the Client, of any nature whatsoever, that entail higher costs than the costs that could be taken into account in the original quotation provided by DATAMAISTER will be for the account of the Client. Any cost reduction resulting from such changes do not give the Client any right with regard to a reduction of the purchase price. However, DATAMAISTER may decide at its own discretion that such changes will result in the payment of a lower purchase price.

2.5 Any changes made to the order may lead to DATAMAISTER exceeding the delivery period indicated prior to the changes. This cannot be invoked against DATAMAISTER .

 2.6 In the event of cancellation of the order, the full costs incurred by DATAMAISTER so far in the context of performing the order will be charged to the Client.

Article 3 – Offers and Quotations

3.1 All offers by DATAMAISTER are free of obligation, unless the offer explicitly states otherwise.

3.2 Descriptions and prices in offers are given subject to reservation and apply only by approximation. The Client cannot derive any rights whatsoever from any errors in an offer.

3.3 DATAMAISTER ’s offers are given based on information and specifications provided by the Client. Offers are based on services to be performed within regular periods and under regular circumstances.

3.4 All prices are exclusive of turnover tax (VAT) and other government levies.

3.5 DATAMAISTER is entitled to change the agreed price if changed market prices or any other developments, such as government measures, currency exchange rates, taxes, duties, levies, etc., give cause to do so. DATAMAISTER shall inform the Client of any price increase as soon as possible in writing. If the price increase occurs within three (3) months of the conclusion of an agreement and exceeds ten (10) percent of the original price, the Client will have the right to rely on cancellation of the agreement in writing within ten (10) days of dispatch of the written notice referred to in the previous sentence, absent which the Client will be deemed to agree to the price increase.

Article 4 – Payment

4.1 Payment must be effected within 14 days of the invoice date by transfer of the amount owed to the bank or giro account stated on the invoice. The Client shall only effect payment in the currency in which the agreed prices have been included, unless otherwise agreed in writing. Any currency risk will be for the Client’s account.

4.2 The Client herewith waives its rights of setoff and suspension of performance.

4.3 If the Client does not comply with its payment obligation on the basis of Article 4.1 of the Terms and Conditions, DATAMAISTER will have the right to terminate or suspend the agreement with the Client in full or in part. In the event of termination or suspension under this provision, the Client will be fully liable for the damage incurred and to be incurred by DATAMAISTER . Furthermore, without prejudice to DATAMAISTER ’s other rights, the Client will owe interest of two (2) percent each month on (the outstanding part of) the invoice as from the date that the payment term is exceeded until the date of full payment of the invoice amount. In that event, DATAMAISTER will be entitled to demand immediate payment of all outstanding invoices and to suspend further deliveries until the entire invoice amount has been paid or satisfactory security has been provided in that regard.

4.4 All court and extrajudicial collection costs incurred by DATAMAISTER as a consequence of the Client’s failure to comply with its payment obligations will be for the account of the Client and will be calculated according to the rate of the Netherlands Bar Association.

4.5 Payments made by the Client will always first be used to settle all charges and interest due and subsequently to settle the oldest payable invoice, even if the Client states that the payment relates to a later invoice.

5.1 The Client shall ensure that DATAMAISTER has all the data and/or other specifications pertaining to the agreement concerned that are required for the performance of the agreement in a timely fashion.

5.3 The Client guarantees that the advertising material supplied is safe and does not contain any viruses, Trojan horses, worms or any other programs that may in any way damage DATAMAISTER ’s computer systems, computer programs and/or websites.

Article 9 – Intellectual Property and Confidentiality

9.1 The intellectual property rights arising during or ensuing from the performance of the order, for example with regard to advertising material and other material created by DATAMAISTER , accrue exclusively to DATAMAISTER , unless otherwise agreed in writing and except for the intellectual property rights already accruing to the Client at the time that this agreement is concluded.

Article 13 – Engagement of Third Parties

13.1 DATAMAISTER is entitled to engage third parties in the performance of an agreement on behalf of and for the account of the Client if there is cause to do so in DATAMAISTER ’s opinion or if the same ensues from the agreement.
