Flipkart: InvoiSIS

Rakshabandhan has always been a high-activity moment in Indian e-commerce, but over the years, the space has become crowded and undifferentiated. Most brands compete on price, speed, and generic gifting assortments. Flipkart wanted to shift the focus from discounts to what really matters - the bond between siblings. The idea was rooted in a simple truth that sisters do a lot for their brothers; things that often go unnoticed or unacknowledged. So this year, Flipkart launched InvoiSIS, the world’s first Rakhi invoice generator. A light-hearted, yet functional tool that lets sisters raise itemised invoices for all the favours they’ve done, from sharing their fancy skincare to saving their brothers from family drama. Each favour came with a certified value, calculated in collaboration with finance educator and sister CA Rachana Ranade. Sisters could then attach a Flipkart wish list that matched their invoice total, turning emotional dues into a real-time, shoppable bill. At the centre of the campaign was a microsite, designed like an old-school Indian invoice pad in pastel colours. The flow was kept simple and inclusive. To launch it, a fun digital film featuring CA Rachana walked audiences through the idea in her signature lecture style, complete with charts, data, and a direct call to action. The campaign conceptualised by the DDB Mudra Group was extended through culturally relevant content, including fictional invoices for iconic sibling duos like Monica & Ross and Aisha & Kabir, meme formats, and influencer engagement, all built for sharing, not scrolling. With minimal media spend and maximum relatability, InvoiSIS encouraged more thoughtful, higher-value gifting across tech, fashion, grooming, and wearables.
