Invoicing built for the
way India does business

Most invoicing tools are built for the West and bolted onto Indian GST rules. We built this from the ground up for Indian SMEs.

Auto CGST / SGST / IGST

Enter your client's state and we automatically split GST correctly — intra-state gets CGST+SGST, inter-state gets IGST, foreign clients get no tax. Zero manual calculation.

India-first

WhatsApp in one tap

Share any invoice directly to WhatsApp with a prefilled message and a public link. Your client opens it on any device — no app, no login, no friction.

Indian SME workflow

Public share links

Every invoice gets a unique public link your client can open in any browser. No account needed on their end. Professional, clean, and permanently accessible.

No app needed

Multi-company support

Run multiple businesses from one login. Switch companies in a click — each with its own invoices, clients, products, and GST details. Perfect for CAs and business owners.

Power users

Complete data isolation

Your invoices, clients, and financials are locked to your company. No other user can ever see your data. Built multi-tenant from day one — not bolted on later.

Security

PDF download — server-side

PDFs are generated on the server using mPDF — not a browser screenshot. Clean, consistent, pixel-perfect every time. Download or email directly from the invoice.

GST Intelligence

Stop doing GST
maths in your head

The system detects intra-state, inter-state, and foreign transactions and applies the right GST split every time.

  • Same state as your company → CGST + SGST applied automatically
  • Different state in India → IGST applied automatically
  • Client outside India → No Tax, clean international invoice
  • Per-product GST rates — 18%, 12%, 5%, or 0% — saved to your catalogue
  • All calculations rounded correctly — no floating point errors

Common questions

Is Invoicing System really free?

+
Yes. Invoicing System is completely free. No credit card required, no time limit. Pro features for power users are coming soon — you'll get advance notice before anything changes.

Does it handle CGST, SGST, and IGST automatically?

+
Yes. Just enter your client's state. If it matches your company's state, the system applies CGST+SGST. If it's a different Indian state, it applies IGST. Foreign clients get no GST. No settings to toggle.

Can I share invoices on WhatsApp?

+
Yes — one click from the invoice screen. It opens WhatsApp with a prefilled message and a public link. Your client doesn't need to install anything or create an account.

Can I manage multiple companies?

+
Yes. You can add multiple companies under one login and switch between them. Each company has completely separate invoices, clients, products, and GST details. Great for CAs and business owners with multiple entities.

Is my data safe and private?

+
Completely. Every query is filtered by your company ID. There is no way for another user or company to access your invoices, clients, or financial data. Multi-tenant isolation was built in from day one.

How do I get access?

+
Fill the short interest form with your company details. We review and create your account manually — this keeps quality high. You'll receive your login credentials by email within 24 hours.
