There is no in-app card checkout for the current MVP. Smaller completed jobs are paid by bank transfer after completion. Larger works use a deposit by bank transfer after you accept the written quote, then a final transfer per the accepted terms. We do not invent a fixed NW8 rate from this page alone.
