Refund & Cancellation Policy
Last updated: July 8, 2026
Overview
Y Lambda (a trade name of Ylambda Tech LLC, San Diego, California) provides professional consulting and software development services rather than physical goods. This policy explains how billing, cancellations, and refunds work. It applies alongside our Terms of Service.
Billing model
We bill either a fixed project fee or an hourly rate; advisory work is typically billed monthly. We do not require an upfront deposit — you are invoiced for work as it is completed, through Stripe. Because you pay only for work already performed, there is normally no prepaid balance to refund.
Cancellation
You may cancel an engagement at any time by giving us written notice (email to contact@ylambda.com is sufficient). On cancellation:
- We stop work as soon as practicable after receiving your notice.
- You are billed only for work performed up to the effective date of cancellation, and for any non-cancellable third-party costs already committed on your behalf with your approval.
- We hand over any completed, paid deliverables.
Refunds
Because we invoice for completed work, refunds are generally limited. However, we want you to be satisfied with the work. If you believe an invoice contains an error, or you are not satisfied with work you have been billed for, contact us within 14 days of the invoice date and we will review it in good faith. Where we agree that a charge was made in error or that billed work was not delivered as described, we will issue a corresponding refund or credit through Stripe.
Billing disputes
If you have a concern about a charge, please contact us first at contact@ylambda.com so we can resolve it directly and promptly. Reaching out to us is almost always faster than filing a dispute with your card issuer, and lets us correct genuine mistakes right away.
How to request a refund or cancellation
Email contact@ylambda.com with your name, the engagement or invoice number, and a short description of your request. We reply within one business day.
Changes to this policy
We may update this policy from time to time. When we do, we will revise the "Last updated" date above.
