Legal
Terms of service
These terms apply to consulting, lab build and training engagements delivered by GNS3 Consulting Service, unless a signed agreement says otherwise.
Last updated: 27 July 2026
01Scope of work
Each engagement is defined by a written statement of work covering deliverables, timeline and price. Work outside that statement is quoted separately before it starts.
02Fees and payment
Fixed-price engagements are invoiced 50% at kick-off and 50% at handover. Time and materials work is invoiced monthly. Invoices are payable within 14 days.
03Client responsibilities
You provide timely access to environments, a named point of contact, and any vendor images or licences needed for the build. Delays in these areas may shift the schedule.
04Third-party software and licensing
GNS3 is open-source software provided by its own maintainers. Vendor device images used inside a lab remain subject to their own licences, which you are responsible for holding. We do not supply, resell or redistribute licensed images.
05Intellectual property
On full payment, you own the topologies, scripts and documentation produced for you. We retain ownership of our pre-existing tooling and methods, and grant you a perpetual licence to use them as part of the deliverables.
06Warranty and liability
We deliver work with professional care and correct defects reported within 30 days of handover at no charge. Labs are emulation environments; results may differ from physical hardware. Our aggregate liability is limited to the fees paid for the engagement.
07Cancellation
Either party may cancel with 14 days' written notice. You pay for work completed and any non-recoverable costs committed up to the cancellation date.
08Changes to these terms
We may update these terms for future engagements. The version in force is the one published on the date your statement of work is signed.
