Policy
Refund & Cancellation
Last updated: May 25, 2026
We want every engagement to result in a satisfied client. This policy explains what to do if it does not. All amounts below are in US Dollars (USD).
Consulting and discovery calls (hourly)
Hours are billed only after delivery. If you are not satisfied with delivered work, contact us within 7 calendar days of receiving the work, describe the issue, and we will issue a full refund for the disputed hours — no further justification required.
Discovery Sprint ($500 fixed)
Fully refundable within 24 hours of the scheduled call if you change your mind. Non-refundable once the call has started. If you proceed to a Custom Engagement within 30 days, the $500 is credited toward the engagement fee.
Custom engagements
Refund terms are defined in the per-engagement written scope. Our default structure is milestone-based: each milestone is invoiced after delivery and is refundable in full if rejected in writing within 5 business days of delivery, with the reasons for rejection stated.
Cancellations
Discovery calls and scheduled meetings can be cancelled or rescheduled by email at no cost, up to 2 hours before the scheduled time. For active engagements, either party may terminate with written notice; work delivered up to the termination date remains payable, and any prepaid amounts not yet earned are refunded within 14 days.
How to request a refund
Email anton@medennikov.com with the subject line "Refund request" and reference the invoice number. We acknowledge requests within 2 business days and process eligible refunds within 7 business days via the original Stripe payment method.
Chargebacks
If you have any concern about a charge, please contact us first. We almost always resolve issues faster directly than through a card-network chargeback. Initiating a chargeback before contacting us may result in suspension of future services.
