General terms.
Algemene voorwaarden · Last updated 5 October 2026
Who these terms apply to
These terms apply to every quote, agreement and piece of work from Sulejman Services (KvK 99469596, BTW NL005389302B41), based at Maarten Lutherweg 19, 1185 AJ Amstelveen, Netherlands ("I", "me"). "You" means the client. Other terms only apply if we agree them in writing.
Quotes and agreements
A quote is valid for 30 days unless it says otherwise. An agreement starts when you accept a quote in writing, email is fine. The price in a quote is fixed for the work that quote describes.
Prices and payment
All prices are in euros and exclude btw, which I add where it applies. For a project, I invoice a deposit of usually 30% when you accept the quote, to reserve the time, and the rest when the work is done and working on your side. Larger projects are paid in agreed parts. Payment is due within 14 days of the invoice date. If payment is late, I may pause the work and charge the statutory interest for commercial transactions.
The AI audit fee is deducted from the project price if you accept a project quote within 90 days of the audit.
Scope and changes
I build what the accepted quote describes. Anything beyond that, such as new features or a bigger scope, is extra work. I tell you before I do it, and we agree the price first.
Delivery and your cooperation
Any timeline I give is an estimate, not a hard deadline, unless we agree one in writing. To deliver I need your input, content and access when needed. Delays on your side move the timeline. For 30 days after you sign off on the work, I fix bugs and make small adjustments at no cost. A bug is when the work does not do what the quote describes. A small adjustment changes something that already exists, like a text, a rule or a field, and takes up to about an hour. New features and bigger changes get their own fixed price first.
Ownership and portfolio
Ownership of the work I deliver moves to you once you have paid in full. Third-party tools, libraries and their licences stay with their owners. I show finished work in my portfolio only with your permission.
Liability
I do the work with care, but I cannot guarantee software is free of every fault. My liability for any claim is limited to the amount you paid for that project. I am not liable for indirect or consequential loss, such as lost revenue or data, except where the law does not allow this to be limited.
Confidentiality
I keep what you share with me confidential and use it only to do the work.
Personal data
If the work involves personal data you are responsible for, we sign a data processing agreement before I work with it.
Cancellation
Either of us can end an agreement in writing. If you cancel, you pay for the work done up to that point.
Ongoing support is paid per month. You can stop it at any time. It ends at the end of the month you have already paid for, and that month is not refunded.
Applicable law
Dutch law applies. Any dispute we cannot resolve together goes before the competent court in the Netherlands.
