Shark Invoice is a WhatsApp-first GST invoicing platform designed for Indian small and medium businesses (SMBs), freelancers, and sole proprietors. It solves the problem of slow payment collection by integrating invoicing directly into WhatsApp, allowing users to create, send, and manage GST-compliant invoices and quotes through a simple chat interface. Each invoice includes a UPI payment link, enabling customers to pay instantly without downloading any additional app.

What Makes Shark Invoice Stand Out

WhatsApp-first workflow: Create invoices and quotes entirely through WhatsApp chat prompts. No need to switch between apps or log into a dashboard to generate documents.
Built-in GST compliance: Automatically handles HSN/SAC codes, CGST/SGST/IGST splits, and place-of-supply logic based on your business details and GSTIN.
UPI on every invoice: Every invoice includes a UPI payment link and QR code. Customers can tap to pay using any UPI app like Google Pay, PhonePe, or Paytm.
Instant quote-to-invoice conversion: Send quotes via WhatsApp, and when a client approves, convert the quote to an invoice with a single tap.
Professional PDFs with public links: Invoices are delivered as clean PDFs and shareable public links that customers can view without signing up.

Small business owners looking to reduce payment cycles by embedding UPI payment links directly into invoices, making it easy for customers to pay instantly.
