How paying works

  1. Press Get my challan – you get a bill with a number like UCL-2026-0042.
  2. Pay it by bank transfer (in Pakistan, from any bank app or branch) or with Payoneer / Wise from abroad, and write the challan number in the note.
  3. Type the transaction ID and the date you paid on the challan page.
  4. Umair checks it (usually the same day) and every lab unlocks automatically. You get a message.
