Flipkart has rolled out a campaign, introducing InvoiSIS, world’s first Rakhi invoice generator.

Conceptualised by DDB Mudra Group, the campaign comprises a film featuring content creator CA Rachana. Built on the insight that sisters do a lot for their brothers, things that often go unnoticed or unacknowledged, Flipkart launched InvoiSIS. A light-hearted, yet functional tool, it 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 is assigned a certified value, calculated with Ranade's help. Sisters could attach a Flipkart wishlist that matched their invoice total, turning emotional dues into a real-time, shoppable bill.

At the centre of the campaign was a microsite, www.invoisis4rakhi.com, designed like an old-school Indian invoice pad in pastel colours.

What we think about it: A delightful departure from the usual emotionally charged Raksha Bandhan narratives, the campaign really stands out. The clever integration of the InvoiSIS tool makes it memorable. The strong, clear call to action is what sets it apart. It doesn’t just tell a story but invites participation.

The film released on 28 July.
