Stop hand-typing PDFs in Word. InvoiceOS auto-calculates CGST/SGST/IGST, drops your UPI ID into the invoice, and shares the link on WhatsApp — so your client pays before they forget.

Why freelancers pick InvoiceOS
Auto GST math
CGST+SGST if your client is in your state, IGST otherwise. InvoiceOS picks based on the GSTIN you save once.
UPI baked into the PDF
Your client opens the invoice, scans the UPI QR, pays in 10 seconds. No Razorpay account needed.
WhatsApp share
One tap sends a clean WhatsApp message with the invoice link. Most freelancers get paid the same day.
Free for the first 5 invoices/month
Plenty for most solo freelancers. Upgrade to Pro (₹499/mo) only when you outgrow it.
Quick questions
Do I need a GSTIN to use InvoiceOS?
No. Freelancers below the ₹20L turnover threshold can still raise invoices — InvoiceOS marks them as 'Not registered under GST' and skips the tax calculation. Add a GSTIN later when you cross the threshold.
Can I send the same invoice on WhatsApp and email?
Yes. Every invoice has a unique shareable link. Drop it into WhatsApp, email, Slack — anywhere. The link opens a clean web view your client can pay or download from.
