About Shark Invoice

Shark Invoice is WhatsApp-first GST invoicing for Indian businesses. Built for solopreneurs, freelancers, and small agencies who run their day from WhatsApp.

Built by Hakkiloo Digital Agency — registered in Bengaluru, Karnataka. We're a small team that ships fast.

Most invoicing tools assume you're at a laptop. Indian SMBs run from WhatsApp. We built around that reality.
