"I never got it" is the most expensive sentence in delivery. A driver's word against a customer's rarely settles anything. ProofCam's Delivery mode records each drop-off as a waybill number, stamped photos, the recipient's name and signature, and a link the customer can open to see the proof.

Proof of delivery (POD) is a Business add-on for Teamspace teams and is included during the 14-day Business trial.

The delivery flow, step by step

The flow is built for one hand and a few taps per stop:

  1. Scan the waybill. Point the camera at the barcode or QR on the label. The reference code fills in automatically, or type it.
  2. Photograph the goods. One tap per photo. Each photo carries the ProofCam stamp (time, GPS position, address, Photo Code) with a title line "Delivery: ".
  3. Recipient details. Enter the recipient's name. The phone number is optional.
  4. Signature. The recipient signs on the screen.
  5. Confirm. The delivery is saved and the share sheet opens with the proof link.

If the drop-off doesn't go to plan, mark it failed or partial and enter a reason instead.

The proof page: /p/ link

Every delivery gets its own link in the form /p/<token>. The token is a random 22-character string generated on the phone, so links can't be guessed from the waybill number. Send it to the customer by chat, SMS or email.

Anyone with the link sees:

  • the status (Delivered, Delivery failed or Partially delivered) and the waybill number,
  • the recipient's name and the signing time,
  • the photos with their time, place and a verify badge for each Photo Code,
  • the place on a map,
  • the recipient's signature and whether it matches the record.

The sender can disable a link; the page then says it's no longer available.

Privacy: the phone number is hashed

If you enter the recipient's phone number, ProofCam normalises it and stores only a SHA-256 hash of it, not the number itself. The hash lets your team match a delivery to a known phone number later, without keeping a readable list of customers' numbers. The recipient's name, photos and signature are stored with the delivery, and the /p/ page is viewable by anyone who has the link, so share it only with the people involved.

Works without signal

Drivers spend a lot of time in lifts, basements and rural roads. POD is built offline-first:

  • The whole flow, including the signature, works with no connection.
  • The delivery is saved on the phone and marked Waiting to sync.
  • When the phone is online, ProofCam uploads the photos, then the signature, then the delivery record, and the status changes to Synced.

The /p/ link is created on the phone, so you can share it right away. It shows the delivery once the upload finishes.

For dispatchers: the Deliveries page

In the Teamspace web portal, Deliveries lists every drop-off with search by waybill and filters by date, status and project. Open one to see photos, signature and the public link, and export the list to CSV or Excel. A delivery.completed webhook can notify your own system.

Tips

  • Photograph the parcel with the door number or shop sign in frame. The stamp shows when and where; the frame shows what.
  • Take a second photo of any visible damage before handing over.
  • Ask the recipient to sign with a finger, slowly. A stylus isn't needed.
  • Keep team upload on so deliveries sync whenever there's signal.

Platforms and plan

Delivery mode works on Android and iPhone. It needs a Business team with the POD add-on, or a team in its trial. The proof page opens in any browser, with no app or account needed for the customer.

FAQ

Does the customer need to install anything?

No. The /p/ link opens in any browser.

What if the recipient refuses to give a phone number?

That's fine. The phone number is optional. The name and signature are required for a completed delivery.

Yes. The link is generated on the phone. It shows the delivery once the phone has synced it.

ProofCam records a signature image together with time, place and stamped photos, which helps provide evidence of the handover. Whether it meets a particular legal requirement depends on your contracts and local rules.
