Vendor due diligence checklist with a dated evidence pack

Vendor due diligence checklist with a dated evidence pack. Keep your original source records together, then date the exact files. It does not prove who made the file, where events happened, whether the content is true, or whether a rule or contract was satisfied.

Your photos and files stay on your device, so keep them.

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.

Your record, one step at a time.

      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.

      Proves / Doesn’t prove

      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 prove who made the file, where events happened, whether the content is true, or whether a rule or contract was satisfied.

      It does not prove who made the file, where events happened, whether the content is true, or whether a rule or contract was satisfied.

      Questions, answered plainly.
