Retail POS

Retail POS

To date, most of India’s grocery retail happens at small local stores (kiranas), accounting for 75-78% of the consumer goods market.

Most of these local stores only track their inventory on a batch level and do not digitize their day-to-day sales. That means that close to 75-78% of a $883 billion market is offline. This leads to challenges.

Downsides

  • Shopowners need to be conscious of their inventory and purchase stock based on what sells and what doesnt. This is usually done through intuition.
  • As all the sales of the day go un-invoiced, shopowners have a difficult time calculating their end of day profits and also managing their accounts.
  • Brands have a pronounced problem. They would like to understand a bit more about which pincodes or localities are the best selling for them. They’d also like to position their inventory ahead of their competitors, as with a lot of FMCG products, products unseen are products unsold.
  • Brands might also like to host targeted campaigns based on perceived interests. But they dont gain a granular understanding of specific markets, more of an aggregated understanding based on the goods sold to higher level distributors.

Roadblock

Big shopping stores, retail outlets and supermarkets tend to have a proper point-of-sale(POS) setup with bar code scanners and a computer with a local/cloud software for billing and invoicing. This is a luxury for kirana store operators who refuse to invest in such a setup despite the challenges.

Solution

A computer vision model trained on various FMCG products and fine-tuned on relevant local items with a client facing app posing as an advanced ‘item scanner’.

Product use-case:
  • A person enters a local mom-n-pop store, picks up items and approaches the billing counter.
  • The billing equipment is nothing but a smartphone on a stand. Shopkeeper scans the items one-by-one within seconds by pointing it at the app opened camera.
  • The app compiles the list of items and generates the bill based on pre-set prices for each item. Quantity of items will also be perceived by the app and duly factored in.
  • Final prices would be editable in case some changes are required based on customer requests or current offers.
  • App displays a final screen with a QR code that can be used for payment. Transaction is recorded. User shares mobile number at their discretion in case they want a copy of the receipt as an SMS.

POC

  • Attempted a simple image classifier by using transfer learning over an existing CNN model trained on consumer product images made available by Stanford research. (Tensorflow made it extremely simple to get started).
  • Model can be trained and refined on different verticals based on categories of items sold. This will improve accuracy and keep manual intervention to a minimum.

If core solution is accepted, this can further foray into becoming a SaaS, linked to other stakeholders like distributors or brands, extending this service into automated inventory fulfilment, store offers, credit-line etc.

Notes/Caveats

  • Requires the model accuracy to be strong and needs to be accommodative to new items being added to it.
  • Requires the interaction medium to be text-light and action-light. Most kirana store operators are technologically unsavvy and will approach this with low inclination.
  • Requires a library of items to be maintained with accurate prices which do fluctuate based on time and region.
  • Lots of nuance required to make it production worthy. Some shops sell various kinds of dal and loose condiments for example.
