This is a fictional example, not a customer record.

From checkout to your account

Buy something

03

Why keep a Proof

A Proof keeps the purchase and later updates together.

01

Recorded after payment

The store’s checkout system must mark the sale complete before Possenda can issue the Proof.

02

Changes are added, not erased

A refund or correction appears below the purchase with its own date.

03

Easy to find

Search by store, item, date, amount or sale reference.

04

Private until you share

A saved Proof is not public. You choose when to share information from it.

Fictional example

Four years with one bicycle.

This is not a customer record. It shows how one bicycle’s purchase, return, service, transfer and warranty records could appear over time.

  1. Purchase recorded

    A bicycle and pannier rack from Prairie Lantern Cycles. The customer saved the Proof at the counter.

  2. Pannier rack returned

    The store added a CAD 100.00 refund. The purchase above did not change.

  3. Service record added

    The owner added a record of work on the bicycle. Possenda did not verify the work.

  4. Item transfer accepted

    The recipient accepted the bicycle transfer in Possenda. The first buyer’s private Proof stayed private.

  5. Records shared for a warranty question

    The owner shared an expiring link to the purchase reference and owner-added warranty and service details. Possenda did not decide coverage.

For customers

Find a purchase when you need it.

Save Proofs from participating stores and search by store, item, date, amount or reference. You decide what to share. A Proof does not by itself establish authenticity, ownership, warranty coverage or return rights.

Practical questions

Common questions.

Which stores participate?

Only stores that have connected and enabled Possenda can issue Proofs. Participating stores will tell customers when a Proof is available.

Do I need an app?

No. A Proof opens in your browser. Continue with Google or Apple when you choose to save it.

What does a Proof show?

It records purchase facts from a participating store’s completed sale. By itself, it does not establish authenticity, ownership, warranty coverage or return rights.

Who can see a saved Proof?

Your saved Proof is private by default. You choose when to share selected information from it.
