Physical Inventory Management via Google Assistant

Over the weekend, we had the opportunity to participate in a developer event organized by Intuit to devise a solution to help small businesses.

DeveloperWeek Hackathon 2017

Piyush Hari represented Dilli Labs LLC at the DeveloperWeek 2017 hackathon on Feb 11 and 12. He paired up with Dudi Shmueli who was looking for technical help around Android. He came up with a fabulous idea – to accept merchant reviews at the point-of-sale (PoS) ! Think of Amazon verified reviews but for in-person (not online) purchases.

Use Case : A customer completes the transaction on a Clover Point-of-Sale (PoS) device. After successful payment, he can leave a Star-Rating (1-5) of the business in his experience.


The idea is motivated by the fact that current rating sites providing aggregated reviews of a business have inaccuracies. Competitors can leave negative reviews without doing business with merchant. Satisfied customers might not bother to log-in to these sites in order to leave a ‘good’ review whereas angry and dissatisfied customers would let it out in their ‘bad’ review.


Clover – now owned by First Data – has PoS devices that is based on Android OS. Clover Android SDK allows one to deploy 3rd party apps to a Clover PoS device that can interject into payment flow of a core Clover order processing app to offer a ‘review’ feature. Broadcasts is a well-known mechanism in Android wherein an app can broadcast an event and other applications can listen to them by registering Broadcast Receivers.

The following video demonstrates the proof-of-concept we built :
