Now keep it safe: three things
  1. Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
  2. Save this receipt to your camera roll.

    Keep the receipt file too. The image is a handy copy; checking needs the file.

  3. Email it to yourself.Email it to myself

    Your mail app opens a draft. Attach your receipt image and receipt file. Don’t attach your photos or documents. Timevolt does not send it or know whether it was sent.

      How to keep notes that hold up

      Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.

      1. Write it down straight away, on paper or in the box on a step.
      2. Put the date, time and place at the top, and who you spoke to.
      3. Use their words where you can; separate what you saw from what you were told.
      4. Sign or initial a paper note, photograph it and add the photo.
      5. Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

      US federal procurement — Army FACNET system · 1996

      A gateway receipt may not reach the buyer

      A supplier had an online receipt, but a system jam kept its bid from the buyer. The reviewer upheld its protest over lost messages and poor handling. The work was done, so it urged bid and protest costs, rather than a replacement contract.

      US federal — Southern District of New York · 2023

      Order records can show who still owes payment

      Two firms disputed whether one still had to pay for orders placed through an online system. The court used order history, emails and bills to award the supplier pay from both. It refused interest and fees for now, with a fresh request allowed.

      Proves

      A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.

      Doesn’t prove

      It does not send or receive an order, authenticate its sender, establish contract acceptance, prove delivery of goods, or satisfy a trading partner's protocol.

      Is an EDI acknowledgment the same as a time receipt?

      No. GSA lists purchase-order and functional acknowledgment transactions within its actual system workflow. A time receipt only dates the bytes supplied to it.

      Does a gateway acknowledgment establish that the buyer's office saw the message?
