Terms of Service

1. Parties

These terms apply between Stacklane (KvK 91500982, BTW NL004895851B52, based in Groningen, the Netherlands) and the business that subscribes to the service. In this document, “we”, “us”, and “Stacklane” refer to Stacklane; “you” and “Customer” refer to your business.

These terms apply to businesses only. We do not contract with consumers within the meaning of Book 7 of the Dutch Civil Code.

2. The service

Stacklane provides a monthly product engineering subscription. Engineers and designers with at least eight years of production experience deliver work against a shared task list at the cadence agreed in the order.

• Engineering: full-stack web, mobile, backend, APIs, infrastructure, DevOps, technical consulting.
• Product Design (optional add-on): brand, product, motion, video, and related creative work.
• All-in: both modules running on one cadence with a single point of accountability.

The exact scope of any specific engagement is defined in an order or scope confirmation. Where the order and these terms conflict, the order prevails.

3. Subscription and pricing

Engineering

€6,000 per month, ex. VAT

Product Design

€4,000 per month, ex. VAT

All-in

€8,000 per month, ex. VAT

Quarterly billing

10% discount on the monthly equivalent

Annual billing

20% discount on the monthly equivalent

All amounts are stated in euros and are exclusive of VAT. Dutch VAT applies where required; reverse-charge rules apply where the Customer is established in another EU member state and provides a valid VAT number.

Invoices are issued in advance for each billing period. The first invoice is payable before the engagement starts, with a default term of 7 days from the invoice date; we begin work once it has been settled. Subsequent invoices are issued on the same day-of-month as the engagement start (or at the start of each quarterly or annual period, if you chose that cadence) and are payable within 14 days of the invoice date. We may suspend the service if any invoice is more than 14 days overdue, after one written reminder. Late payment accrues statutory commercial interest under article 6:119a of the Dutch Civil Code.

4. Pause, cancellation, and renewal

The subscription renews automatically at the end of each billing period (monthly, quarterly, or annually, depending on the period you chose).

• Cancel: tell us in writing before the next billing cycle starts. We stop the next charge. No notice period, no kill fee.
• Pause: tell us in writing. We stop billing and work pauses until you ask us to restart. No minimum pause length, no maximum.
• Pre-paid quarterly or annual periods: if you cancel mid-period, unused months are refunded pro rata at the discounted rate; the discount is not clawed back.
• Restart: ping us. We resume on the next agreed start date and bill from that date.

5. Deliverables and intellectual property

Once an invoice covering a deliverable has been paid in full, all intellectual property rights in that deliverable transfer to the Customer to the maximum extent permitted by Dutch law. Where transfer is not possible (for example, moral rights), the Customer receives an irrevocable, perpetual, worldwide, royalty-free, sub-licensable licence to use, modify, and sublicense the deliverable for any lawful purpose.

• Background IP. Stacklane retains rights to pre-existing tooling, libraries, templates, and methods that exist independently of the engagement. The Customer receives a perpetual licence to use them as part of the delivered work.
• Open-source dependencies. Governed by their own licences, which remain unaffected by these terms.
• Portfolio reference. We may name the Customer and reference the engagement publicly (for example on the /work page) unless the Customer asks us in writing not to.

6. Confidentiality

Each party keeps the other's non-public business and technical information confidential, both during the engagement and for three years after it ends. Standard carve-outs apply: information that is or becomes public without breach, information already known before disclosure, and disclosures required by law or by a competent court.

7. Service quality and warranties

We deliver to the professional standard of a senior engineering team. We provide reasonable effort against the agreed scope. We do not guarantee specific outcomes, feature counts, or completion dates unless an order explicitly contracts a fixed deliverable.

• Bugs and regressions reported during an active subscription are addressed as part of the ongoing work, at no extra charge.
• Code is delivered with reasonable tests and documentation. Production deployment, on-call response, and uptime monitoring are the Customer's responsibility unless explicitly part of the order.
• We do not offer a service-level agreement for uptime or response time unless one is signed separately.

8. Liability

To the maximum extent permitted by law, Stacklane's total liability under or in connection with the agreement is limited to the fees paid by the Customer in the three months preceding the event giving rise to the claim.

We are not liable for indirect or consequential damages, including loss of profit, loss of revenue, loss of opportunity, loss of data, or reputational damage. The limits in this section do not apply where liability cannot be limited by law, in particular in cases of intent or gross negligence on the part of Stacklane's management.

9. Force majeure

Neither party is liable for failure to perform caused by events outside its reasonable control: war, civil unrest, natural disasters, pandemics, prolonged infrastructure outages, cyber attacks on third-party providers, or government action. The affected party notifies the other promptly and both parties cooperate in good faith to mitigate.

10. Termination

• For convenience: either party may terminate as described in section 4 (cancellation).
• For cause: either party may terminate the agreement on written notice if the other materially breaches and does not cure within 30 days of written notice of the breach.
• Immediate termination by Stacklane: insolvency or bankruptcy of the Customer, demonstrable fraud, or use of the service for unlawful purposes.
• On termination: outstanding invoices become immediately due. The Customer receives the final deliverables. Confidentiality, IP transfer of paid deliverables, and limitations of liability survive termination.

11. Governing law and jurisdiction

Dutch law governs the agreement. The United Nations Convention on Contracts for the International Sale of Goods (CISG / Weens Koopverdrag) does not apply.

Any dispute that cannot be resolved between the parties is brought exclusively before the District Court of the Northern Netherlands (Rechtbank Noord-Nederland), location Groningen, unless mandatory law provides otherwise.

12. General

• Entire agreement. The order, these terms, and any data processing addendum form the entire agreement between the parties on the subject matter.
• Severability. If a clause is held unenforceable, the rest remains in effect. The parties replace the unenforceable clause with one that closely matches its economic intent.
• Assignment. The Customer may not assign rights or obligations without our written consent. We may assign to a legal successor on written notice.
• Notice. Email to hello@stacklane.co and to the Customer's account contact is a valid form of written notice.
• Order of precedence. If the order, these terms, and any addendum conflict, the more specific document prevails.

13. Updates to these terms

We may update these terms. The “Last updated” date at the top reflects the most recent revision. Material changes that affect active customers are notified by email at least 30 days before they take effect. Continued use of the service after that date constitutes acceptance.
