InvoiceAI — Free GST Invoice Generator & AI Billing Software for India
Free GST invoice generator for Indian freelancers and SMEs. AI contract generation, digital business card, UPI payments, e-signature, client portal, and expense tracking — shipped as a single freemium product.
CONTEXT
InvoiceAI is a free GST-compliant invoice generator built for Indian freelancers and small businesses. It replaces expensive billing software with an AI-assisted workflow — from creating a professional GST invoice to sending it with a UPI payment link in under 3 minutes.
The AI contract generator produces legally structured service agreements, NDAs, and freelance contracts without a template library. Contracts are e-signed via a secure signing link and stored with a full audit trail.
The digital business card creates a shareable profile at card.invoiceai.tech — with lead capture, UPI QR code, portfolio links, and NFC or QR-based sharing.
The client portal gives customers a branded view of invoices, contracts, and project milestones — reducing payment delays and support emails.
