Legal
Terms
The general terms every engagement starts from. The agreement we sign together can add to these; it cannot quietly take away from them.
Last updated 4 September 2026
1. Who
These terms apply to every offer made by and every agreement with Plathena, James Cookstraat 16-I, 1056 RZ Amsterdam, Chamber of Commerce number 73369446 (“we”), and the client (“you”).
2. Quotes and prices
A quote is valid for thirty days. A fixed-price quote covers exactly the scope written in it; anything not written in it is not included. Prices exclude VAT. Indicative prices on our website are not an offer.
3. Changes
Scope changes are priced in writing before they are built, and only built once you have agreed to the price. Work you ask for outside the scope, and that we have not priced, is not chargeable and not owed.
4. Payment
Fixed-scope work is invoiced in instalments set out in the quote, typically at the start and at agreed milestones. Ongoing development is invoiced monthly in advance. Invoices are due within fourteen days. If an invoice is overdue we may pause work after giving notice.
5. What you own
On payment of the invoices for the work in question, you own the software we wrote for you and the intellectual property in it. We keep the right to reuse general know-how, techniques and non-client-specific components. Open-source software we use stays under its own licence, which we will identify on request.
6. Your part
You give us the access, information and decisions we need in time to keep the plan. If a week's demo cannot happen because we are waiting on you, the plan moves by the same time.
7. Confidentiality
Everything either of us learns about the other's business in the course of the work is confidential, during the engagement and for three years afterwards, unless it is public or we are required by law to disclose it.
8. Liability
Our liability for any engagement is limited to the amount you paid us for that engagement in the twelve months before the event giving rise to the claim, except where the law does not allow that limit. We are not liable for indirect loss, including lost profit or lost data where a backup you were responsible for was not made.
9. Ending it
Ongoing development can be ended by either side at the end of any month with one month's notice. A fixed-scope build can be ended by you at any time; you pay for the work done to that point, and you receive everything built so far. Either side can end an agreement immediately if the other materially breaches it and does not fix it within fourteen days of being asked to.
10. Law
Dutch law applies. Disputes go to the competent court in Amsterdam, after we have both genuinely tried to settle them by talking first.
