Venture 8: Proof of purchase

By Drew Broadley

We’d like to clarify that each of these first canvases represent a concept we’re investigating, based on known pain points. We’re in the process of validating them more, and will choose a small subset to start testing as proofs of concept.

My turn to write a blog post or few. I’m Drew Broadley, Executive Director of Data Ventures. It’s my job to get out there and front for Data Ventures, finding us potential partners and smoothing the way for the team to make awesome things happen.

There is an important little white piece of paper printed each time we make a purchase at our favorite store. Yet, many of us share the pain of losing it and then needing it at a point in the future we never thought we would.

This venture isn’t about that piece of paper, it’s all about the experience. We’re covering off one of the uses for it, proving a purchase. It’s also about proving there’s no reason to capture anyone’s personal information to make a return, which makes many customers feel like they aren’t trusted by the store.

Often innovation is as boring as taking something physical and moving it into a digital version. This misses the important part of wondering about the way you can change how the whole experience works. This isn’t one of those cases.

We want to make it so a receipt isn’t required at all, and remove a step in the purchase flow.

When you return a product, you bring it with you and the card you made the purchase with. At the returns desk, they swipe your card, scan the barcode of the product and can see whether you bought it. No smartphone app that requires you to register, while gaining almost as much personal insight as playing Cards Against Humanity with you.


This connects the information ONLY for the combination of the card and product purchased, and not every purchase or every product that a person has made.

Sorry, though — if you make purchases with cash, you’ll still need to keep that receipt. Purchases with cards are surpassing 70% and rising, so it makes sense we focus on those.

We’re aware of others offering similar things to this, but only through their range of stores. We love that others are doing it, and we want to work with companies like this to make it better for every store so the experience is consistent.

Note: This is not covering the need for expense claims, which would still require the receipt. That’s a whole other venture!


  • Many people who buy something at a store, don’t keep the receipt as proof of purchase.
  • This means that:
  • -> many products don’t get returned when they should, or
  • ->can’t be returned as there’s no proof of which store the product was bought at, or
  • ->it takes a lot of effort for the service team to look up a past purchase while the purchases tries to look through their internet banking records (if they have access to them).

Existing alternatives

  • Paypr by Paymark (recently closed).
  • Briscoes Group who currently offer this using last four digits of card used for purchase.


  • Retailers (online, and bricks and mortar).
  • Consumers.
  • Insurers.

Early adopters

  • Retailers who tend to aim for the lower cost stock that tend to service a lot of broken products
  • Consumers who purchase at these stores regularly

Value proposition

  • Reduces the time needed to prove a purchase, both for on the consumer no longer needing to find a receipt ,and the retailer no longer having to look through their previous purchases.
  • Not relying on a single payment method.
  • Reduces the risk of receipt fraud for the merchant.
  • Saves paper.

High level concept

  • Make product returns easy between consumers and retailers.


  • We will match an electronic payment to a purchase in the POS when it wasn’t previously connected to maintain as much privacy and security as possible.
  • This focus is not on the consumer to have the technology, but the retailer so there is accessibility beyond people who have smartphones.


  • Past experience around proving purchase electronically.
  • Learning from the past ventures from ourselves or others we are able to bring together a simple solution.

Revenue streams

  • A retailer would typically pay for a product like this with a base monthly access fee, graded to their required support levels, integration or transaction numbers.
  • Consumers could pay a small fee for the time saving, if they didn’t keep their receipt.

Cost structure (1 lowest, 5 highest)

  • Complexity: 3.
  • Risk: 2.
  • Effort: 3.
  • Acquisition: 2.

Key metrics

  • Time saved.
  • Accuracy of returns.
  • Reduction of fraud.


  • Retail NZ.
  • Banks.
  • Point of sale providers.
