GST Invoice & Business Finance Toolkit — For Indian Freelancers & Small Businesses

Invoice correctly. Know what you owe. See the shortfall coming.

Most Indian freelancers and small businesses run on a WhatsApp-forwarded invoice format, a rough idea of what's owed, and a nasty surprise at GST filing time. This workbook replaces all three.

Built by someone who worked inside Indian banking — in rupees, for Indian rules, not an American template with a currency symbol swapped out.

Seven sheets

🧾 Tax Invoice — A GST-compliant invoice with your details, HSN/SAC codes and line items. Pick intra-state or inter-state and it splits into CGST + SGST or applies IGST automatically. You never calculate tax by hand again.

📒 Invoice Register — 100 rows logging everything billed, with the two figures that matter most: total GST collected (money that isn't yours — set it aside) and unpaid invoices outstanding.

💰 Cash Flow Forecast — 12 months. Each month's closing balance carries into the next, so a shortfall shows up months before it arrives.

📊 Profit & Loss — Monthly income and expenses across 11 categories, with margin and a full-year column.

⚖️ Break-even Calculator — How much you must sell before you make a single rupee of profit.

⚙️ Settings — Your GSTIN, bank details and invoice numbering, entered once.

📖 Read Me — Exactly where to type and what not to touch.

Who it's for

• GST-registered freelancers: designers, developers, consultants, editors, tutors
• Small businesses and agencies billing clients across states
• Anyone who has ever been surprised by their GST bill

Not for: businesses that need e-invoicing through the IRP or automated GST return filing — use your accounting software or CA for those.

FAQ

Why not a free invoicing app? Apps are good at invoices. This connects invoices to what you actually keep: GST set aside, cash flow, profit and break-even, in one file you own.

Do I need Excel? No. Free Google Sheets works.

Can I add my logo? Yes, insert it in the invoice header.

Is this tax advice? No. It's a template and doesn't file anything. Confirm your registration status, HSN/SAC codes and filing obligations with a qualified chartered accountant.
