Reasonable pre-approved expenses (travel, software licenses required for the engagement, third-party API costs) are reimbursed at cost with receipts; client approval is required for any single expense over $500.

Expenses are passed through at cost with no markup. Zeroth Agents does not profit on expense reimbursement. Travel is economy class for flights under 5 hours, business class for longer flights if pre-approved. Remote-first engagements minimize travel expense exposure.
