This website presents vierkant GmbH’s products and services. It has no online shop, shopping cart or electronic ordering function. We work with consumers and businesses. Enquiries and quotation discussions take place particularly by phone or email.
Product descriptions are not binding offers. The products or services commissioned and the conclusion of a contract depend on the individual quotation and agreement. Contracts may also be concluded by phone or email; this page does not prescribe a particular form.
This page provides general information about the contract process and consumer rights. It introduces no additional liability restrictions or blanket exclusions of statutory rights. The actual agreement and applicable law govern each contract.
The individual quotation specifies the scope of work, technical requirements, prices, payment arrangements, delivery or performance dates and any shipping or installation charges. Consumer quotations state the total price including applicable VAT and additional charges. Where the nature of a service prevents advance price calculation, the calculation method is stated. This website makes no general promise of a particular delivery period. Custom manufacturing, engineering, product development and software requirements are agreed for each project.
Statutory rights applicable to the contract type remain in place. These are not excluded across the board for consumers buying used or refurbished products. An additional commercial guarantee exists only if expressly given and does not affect statutory rights.
Even without an online shop, distance-selling or off-premises consumer contract rules may apply. This depends on the actual process, including whether a contract is concluded under an organised distance sales or service-provision scheme.
Where a statutory right of withdrawal exists, the period is generally 14 days. For goods it generally starts on receipt by the consumer or a nominated third party other than the carrier; separate deliveries or instalments may be subject to other statutory rules. For services it generally starts on conclusion of the contract. The period does not start before the required information is properly provided. The complete withdrawal instructions appropriate to the particular contract and the model withdrawal form are supplied with the individual quotation or contract on a durable medium, such as email. This overview does not replace those documents.
You may exercise an existing right by an unequivocal statement to vierkant GmbH, for example by email to info@vierkant-design.de, by phone at +49 201 765 040 85, or by letter to Stemmering 34, 45259 Essen, Germany. No reason is required. Returning goods without a clear statement is not itself a declaration of withdrawal. Sending the statement before the deadline is sufficient.
The applicable statutory rules govern the reversal of a contract after valid withdrawal. Refunds are generally due within 14 days of receipt of the withdrawal; for goods, statutory rights to withhold reimbursement until receipt of the goods or evidence of return may apply. Goods must generally be returned within 14 days of the withdrawal notice.
For goods, we bear the return costs following statutory withdrawal. Compensation for diminished value or services is due only where the statutory conditions are met.
A statutory right of withdrawal may be excluded under section 312g(2)(1) of the German Civil Code for non-prefabricated goods made on the basis of an individual choice or decision by the consumer, or goods clearly personalised to their needs. Manufacturing only after an order, or undertaking an engineering project, does not automatically meet this exception; the actual contract must be assessed.
Different rules apply to services and digital content. Starting performance early does not automatically remove the right of withdrawal. Where needed, the statutory express statements concerning early performance, compensation and possible expiry of the right are obtained separately in advance. This page does not replace those statements.
These instructions apply to consumers purchasing goods under distance or off-premises contracts where a statutory right of withdrawal exists. The exception for certain custom-made goods explained above must be considered. Services and digital content require instructions adapted to the particular contract.
You have the right to withdraw from this contract within fourteen days without giving any reason.
The withdrawal period expires fourteen days after the day on which you, or a third party other than the carrier and indicated by you, acquire physical possession of the goods. For several goods ordered in one order and delivered separately, the period starts upon possession of the last good. For a good delivered in multiple lots or pieces, it starts upon possession of the last lot or piece.
To exercise the right of withdrawal, you must inform us (vierkant GmbH, Stemmering 34, 45259 Essen, Germany, phone +49 201 765 040 85, email info@vierkant-design.de) of your decision by an unequivocal statement, such as a letter sent by post or email. You may use the model form below, but this is not obligatory. Sending your communication before the period expires is sufficient to meet the deadline.
If you withdraw, we reimburse all payments received from you, including delivery costs except supplementary costs resulting from your choice of delivery other than the least expensive standard delivery offered by us, without undue delay and no later than fourteen days after we are informed of your decision. We use the same means of payment as for your original transaction unless you expressly agree otherwise; you incur no fees for reimbursement.
We may withhold reimbursement until we receive the goods back or you supply evidence of sending them back, whichever is earlier.
You must send back or hand over the goods to vierkant GmbH, Stemmering 34, 45259 Essen, Germany, without undue delay and no later than fourteen days after informing us of your withdrawal. The deadline is met if you send the goods before the fourteen-day period expires.
We bear the cost of returning the goods. You may contact us to arrange a suitable return method, particularly for goods unsuitable for normal postal return. Contacting us or using a particular shipping method is not a condition for effective withdrawal.
You are liable only for diminished value resulting from handling beyond what is necessary to establish the nature, characteristics and functioning of the goods.
Complete and return this form only if you wish to withdraw from the contract. Its use is voluntary.
