Log in to ProofDrop and go to Hyfin Invoice Sync. Enter the invoice number, total amount, and customer name — the same details you already have in Hyfin. No double entry.
ProofDrop uses these to create or update the invoice in Hyfin on your behalf.
ProofDrop creates a one-time confirmation link for that specific invoice and encodes it into a QR code. It is tied permanently to that invoice number.
No app required for the recipient — any smartphone camera will scan it.
ProofDrop calls the Hyfin API and attaches the confirmation URL to the invoice's customer memo and as a file attachment. Your Hyfin invoice is updated in real time.
No copy-pasting, no manual steps. The link also travels with the digital invoice sent by email or SMS.
Click "Print Delivery Slip" to open a branded slip with your company name and logo. A print dialog opens automatically.
Staple or clip the slip to the physical Hyfin invoice before the driver leaves the warehouse.
When the goods arrive, the receiving business scans the QR code with any smartphone camera. A simple page opens showing the invoice number.
They optionally type their name and a short note, then tap "Confirm Receipt". Done in under 10 seconds.
The moment the delivery is confirmed, you receive a notification. The record — timestamp, receiver name, and IP address — appears in your dashboard.
Export all confirmations as a CSV at any time for your records or accounting team.
Your customers don't need to do anything in advance. When the delivery arrives, the driver hands over the invoice with the slip attached.
Point any phone camera at the code on the delivery slip. No app needed.
A simple page shows the invoice number and an optional name/note field.
One tap. Done in under 10 seconds. You get notified instantly.

No. They point their phone camera at the QR code and tap the link that appears. It opens in their browser. No app, no account, no sign-up required.
The confirmation link is also embedded in the digital Hyfin invoice. If the customer receives the invoice by email or SMS, they can confirm receipt by clicking the link in the message.
The second scan shows a message that the delivery has already been confirmed, along with the original confirmation timestamp. The record cannot be overwritten.
Yes. On the Generate QR page, switch to bulk mode and paste a list of invoice numbers. ProofDrop generates all the codes and packages them as a ZIP file you can download.
No. ProofDrop works alongside Hyfin. You continue using Hyfin for invoicing and payments. ProofDrop adds the delivery confirmation layer on top — reading and writing to your Hyfin invoices automatically.
ProofDrop records the confirmation timestamp, the receiver's name (if provided), and the IP address of the device used. This creates a clear audit trail sufficient for most wholesale disputes.
