Terms & Policies
Clear guidelines for our professional relationship
For service engagements, work is typically delivered in milestones with clear acceptance criteria. Paid amounts for completed and accepted milestones are non‑refundable. If a deliverable does not meet the agreed scope, I will promptly address issues or offer a proportional refund for the unmet portion. Chargebacks should be preceded by contacting support so we can resolve any issue swiftly.
Digital products (e.g., source code, documentation) are non‑returnable once delivered.
Either party may cancel before the next milestone starts. Pre‑payments for unstarted milestones are refundable. For time‑and‑materials work, billed time up to the cancellation date remains payable.
I do not sell physical goods. If a project involves third‑party hardware, the vendor's return policy applies.
For any questions, billing, or project support, contact:
Response time: within 2 business days
