Slim Folderen B.V. · Version 2026-10 · Last updated: 3 October 2026
1.Definitions
In these General Terms and Conditions, the following definitions apply:
- Slim Folderen: Slim Folderen B.V., established at Dynamostraat 44, 1014 BK Amsterdam, Dutch Chamber of Commerce (KvK) number 91042011.
- Customer: the business — a legal entity or a natural person acting in the course of a profession or business — that creates an account and uses the platform.
- User: a natural person who has access to the platform on behalf of the Customer.
- Platform: Slim Folderen's online dashboard and API for managing and sending physical mailings.
- Credits: the prepaid unit of payment used on the platform to purchase services.
- Welcome Credits: Credits granted at no charge that Slim Folderen may award once to a new Customer under the conditions of Article 5.
- Trial Shipment: the one shipment for which Welcome Credits may be used, as described in Article 5.
2.Applicability and business use
These terms apply to all offers, agreements and services of Slim Folderen. By creating an account or using the platform, the Customer accepts these terms.
The platform is intended exclusively for businesses and is not offered to consumers. The User who creates an account declares that the Customer is acting in the course of a profession or business and that he or she is authorised to represent the Customer in doing so.
Slim Folderen may ask the Customer for a KvK number or a comparable registration and may verify those details in the Dutch Trade Register (Handelsregister).
3.Credits — purchase and use
The platform works with a prepaid credit system. Credits are purchased in advance and then deducted per service provided (printing, packing and shipping).
Available credit bundles and applicable volume discounts are shown in the dashboard. Volume discounts are calculated automatically based on the volume purchased.
Welcome Credits are not purchased Credits. Their use is additionally subject to the conditions of Article 5.
4.Credits are non-refundable
Credits are non-refundable and cannot be refunded to the payment method with which they were purchased, nor converted into any other value or currency.
Credits have no expiry date and remain valid indefinitely for as long as the account is active.
On termination of the account, any remaining credit balance is forfeited without any right to a refund. Slim Folderen advises Customers to match their balance to their expected usage.
Exception: in the event of a demonstrable technical failure caused by Slim Folderen as a result of which credits were wrongly deducted, the credits concerned will be restored after verification via Info@slimfolderen.nl.
5.Welcome credits and trial shipment
Slim Folderen may award a new Customer Welcome Credits once (currently 100 credits) to try the platform with one free Trial Shipment. There is no entitlement to Welcome Credits.
Welcome Credits are only awarded to a Customer with a valid, active registration in the Trade Register of the Dutch Chamber of Commerce (KvK) or a comparable registration, which Slim Folderen can verify. Welcome Credits are awarded no more than once per business and per person, telephone number and email address. A new or additional account for the same business or person, or with the same telephone number or email address, does not confer any right to new Welcome Credits.
As long as the Customer has not yet purchased a credit bundle, Welcome Credits may be used for the platform's AI features and for one Trial Shipment: one copy of one brochure of no more than the number of pages stated in the platform (currently 8), sent to the Customer's own business address as registered with the KvK or to a business recipient selected via the KvK search function in the platform. Bulk orders and batch, campaign and webhook shipments are not covered by the Trial Shipment. Costs exceeding the Welcome Credits are settled with purchased Credits. After the Customer has purchased a credit bundle, any remaining Welcome Credits may be used for all services.
Slim Folderen may refuse a Trial Shipment to a recipient who received a Trial Shipment from another Customer shortly before. If a Trial Shipment is cancelled, or is not carried out by Slim Folderen, the Welcome Credits used will be credited back as Welcome Credits and the Trial Shipment will be deemed not to have been used.
Welcome Credits cannot be exchanged for money and are non-transferable and non-refundable. When accounts are merged, Welcome Credits are not added together.
Slim Folderen may refuse or withdraw Welcome Credits and let unused Welcome Credits lapse in the event of (a reasonable suspicion of) abuse, such as creating multiple accounts or providing incorrect information, and when the conditions of this article are not (or are no longer) met. Slim Folderen may change or end the welcome offer; except in cases of abuse, this does not affect Welcome Credits already awarded.
6.Payments
Payments are made via Mollie B.V. (a payment institution registered in the Netherlands). Slim Folderen does not store any payment details; these are managed by Mollie in accordance with the PSD2 Directive.
On the first payment via iDEAL or SEPA Direct Debit, a direct debit mandate is recorded so that auto-reload can be carried out automatically. The Customer may revoke this mandate at any time via the dashboard.
All prices are exclusive of VAT, unless stated otherwise. The applicable VAT rate (standard 21%) is shown at checkout.
7.Auto-reload
The Customer can enable the auto-reload function. When the set threshold is reached, credits are automatically purchased via the recorded payment method. The Customer is responsible for ensuring sufficient funds on the linked bank account or card.
Auto-reload can be disabled at any time via the dashboard. Transactions that have already been processed cannot be reversed.
8.Services and liability
Slim Folderen endeavours to keep the platform available and to process orders on time. Delay that is not attributable to Slim Folderen (PostNL, force majeure) releases Slim Folderen from liability.
The liability of Slim Folderen is in all cases limited to the amount of the credits paid for the order concerned.
9.Intellectual property
The Customer warrants that the documents and designs supplied do not infringe any intellectual property rights of third parties. Slim Folderen is not liable for any damage arising from material supplied.
10.Privacy policy
Personal data (including recipients' data) is processed in accordance with the General Data Protection Regulation (GDPR). Slim Folderen acts as processor for recipients' data. For the account and contact details of the Customer and its Users, Slim Folderen is the controller.
To prevent abuse of the welcome offer (Article 5), Slim Folderen checks the KvK number provided in the Trade Register and compares the KvK number, the telephone number and the email address with previous registrations. For this purpose we store only a one-way hash of these details: a key from which the original details cannot be derived. The legal basis is our legitimate interest in fraud prevention (Art. 6(1)(f) GDPR). We keep these keys for as long as is necessary for this purpose.
More information is available via privacy@slimfolderen.nl.
11.Printed matter, reprints and returns
Printed matter from Slim Folderen is custom-made: it is printed per order on the basis of the PDF supplied by the Customer and the delivery address provided. Because the platform is offered exclusively to businesses, no right of withdrawal applies; for custom-made products it is moreover excluded (Article 6:230p(f) of the Dutch Civil Code (Burgerlijk Wetboek, BW)). Printed matter is not physically returned.
Credits for correctly printed and shipped printed matter are non-refundable, including in the event of a change of mind, an error in the supplied file (colour, bleed, content) or an incorrect address that the Customer provided itself.
In the event of a demonstrable production error by Slim Folderen — incorrect printing, damage in our production or shipment to an address other than the one the Customer confirmed — we will reprint at no charge or restore the deducted credits. Report this within 14 days of delivery via Info@slimfolderen.nl with the order number and photos of the printed matter received.
12.Amendments and governing law
Slim Folderen reserves the right to amend these terms. Registered Customers will be notified of this by email in good time. Continued use after the effective date constitutes acceptance.
These terms are governed by Dutch law. Disputes are preferably resolved through mutual consultation; if that is not successful, the competent court in Amsterdam has jurisdiction.
