Free GST Invoice Template India: Complete Guide for Freelancers & SMBs
Your invoice is more than just a piece of paper asking for payment. It's a legal document, a tax record, and your first impression with clients. If you're a freelancer or small business owner in India, creating a proper free GST invoice template India isn't optional—it's essential for staying compliant with GST rules.
The good news? You don't need to hire an accountant or buy expensive software. This guide will show you exactly how to get, customize, and use a compliant free GST invoice template that works for your business.
Why You Need a Proper GST Invoice Template
A standard invoice isn't enough anymore. If you're GST registered, your invoices must follow specific rules laid down by the GSTN (Goods and Services Tax Network).
Here's the reality: using a wrong or incomplete invoice template can lead to:
- ITC rejection: Your clients won't be able to claim Input Tax Credit (ITC)
- Penalty notices from tax authorities
- Audit complications when documents are questioned
- Client frustration when their accounts team rejects your invoice
A proper free GST invoice template India includes all mandatory fields and calculations, protecting both you and your client.
Key Takeaway: A compliant GST invoice template saves you from penalties while ensuring your clients can claim ITC without issues.
Essential Fields in a GST-Compliant Invoice Template
Before you download or create a template, you need to know what must be included. The GST law (under Section 31, CGST Act) requires specific information.
Mandatory Details Every Invoice Must Have
Your free GST invoice template must include:
- Invoice number and date (unique sequential numbering)
- Your business name, address, and GSTIN
- Client name, address, and GSTIN (if registered)
- HSN/SAC codes for each product or service
- Detailed description of what you're charging for
- Quantity and rate (for goods) or just rate (for services)
- Applicable GST rate (5%, 12%, 18%, or 28%)
- Tax amount calculated separately (SGST and CGST)
- Total invoice value with taxes
- Place of supply
- Your authorized signatory name
What Many Freelancers Get Wrong
Most freelancers miss the HSN/SAC code or don't calculate SGST and CGST separately. Let's fix that.
For service providers (like you if you're a freelancer), use SAC codes. Services generally fall under:
- 998519 – Other professional, technical and business services not elsewhere classified
- 998361 – Accountancy and auditing services
- 998312 – Management and other consultancy services
For goods, use HSN codes (8-digit numbers like 61090000 for clothing).
Key Takeaway: Missing HSN/SAC codes and separate tax calculations are the #1 reason invoices get rejected—include them in your template from day one.
Free GST Invoice Template Options for India
You have three main routes: download a ready-made template, use online tools, or create your own in Excel.
Option 1: Download a Free Template (Quick Start)
If you want something right now, the best approach is:
- Visit freeinvoicebill.com – they offer free, GST-compliant invoice templates
- Download the Excel or PDF version
- Add your business details
- Use for all future invoicing
The advantage? It's already formatted correctly, with formulas for tax calculations built in.
Option 2: Create Your Own in Google Sheets or Excel
If you prefer full control:
- Create columns for Item Description, SAC Code, Quantity, Rate, Amount
- Add rows for SGST (half of GST rate) and CGST (half of GST rate)
- Use formulas to auto-calculate taxes (this saves time and errors)
- Include your GSTIN and client's GSTIN prominently
Real Example:
| Item | SAC | Rate (₹) | SGST @9% (₹) | CGST @9% (₹) | Total (₹) |
| Web Design Services | 998519 | 10,000 | 900 | 900 | 11,800 |
| Content Writing (3 articles) | 998519 | 5,000 | 450 | 450 | 5,900 |
| Subtotal | 15,000 | 1,350 | 1,350 | 17,700 |
See how SGST and CGST are shown separately? That's non-negotiable.
Key Takeaway: Whether you download or create your own, ensure HSN/SAC codes, separate SGST/CGST calculations, and both GSTINs are clearly visible.
Practical Examples: Using Your GST Invoice Template
Let's walk through real scenarios to show how your free GST invoice template India works in practice.
Scenario 1: Freelance Developer (18% GST)
You're a freelance app developer in Bangalore. Your client is Acme Tech Ltd. (GST registered), and you've delivered a mobile app project for ₹50,000.
Your invoice using the template would look like:
| Description | SAC Code | Amount (₹) |
| Mobile App Development | 998519 | 50,000 |
| SGST @9% | — | 4,500 |
| CGST @9% | — | 4,500 |
| Total Invoice Value | — | 59,000 |
Your client can claim ₹9,000 as ITC, which is why the proper format matters.
Missing SGST/CGST breakdown? The client's accountant will reject it.
Scenario 2: Unregistered Freelancer (No GST)
If your annual turnover is below ₹40 lakhs, you don't need GST registration. Your invoice is simpler—no GST rates, no SGST/CGST split.
For example, if you earned ₹3,00,000 in a financial year:
| Description | Amount (₹) |
| Freelance Copywriting Services | 3,00,000 |
| Total (No GST) | 3,00,000 |
Note: You still need a proper invoice with your name, address, invoice number, and date. You don't need a GSTIN, but include your PAN instead.
Scenario 3: Service Provider with Multiple Clients (Mixed Rates)
You run a small digital agency with three invoices in one month:
| Client | Service | Amount (₹) | GST Rate | Total with GST (₹) |
| XYZ Corp | Consulting | 25,000 | 18% | 29,500 |
| ABC Startup | Logo Design | 8,000 | 18% | 9,440 |
| DEF Retail | Social Media | 12,000 | 18% | 14,160 |
Each invoice must have a unique invoice number and date. Your free GST invoice template should auto-increment the invoice number to avoid duplicates.
Key Takeaway: Real examples show why consistent formatting across invoices prevents client rejections and keeps your records audit-ready.
GST Invoice Template vs. Regular Invoice Template
Not sure what the difference is? Here's a quick comparison:
| Feature | Regular Invoice | GST Invoice Template |
| Mandatory GSTIN | No | Yes (if registered) |
| HSN/SAC Code | Not needed | Required |
| Separate SGST/CGST | No | Yes, must show separately |
| ITC Eligibility | No | Yes (if format is correct) |
| Penalty Risk | Low | High (if non-compliant) |
| Suitable For | Below ₹40 lakh turnover (unregistered) | GST registered businesses |
Bottom line: If you're GST registered, a regular invoice template won't protect you. Always use a GST-compliant template.
Key Takeaway: Using a regular template when GST registered exposes you to ITC rejection and audit risk—stick to a proper GST invoice template.
How to Customize Your Free GST Invoice Template
Once you download your free GST invoice template India, here's the checklist:
Step 1: Add Your Business Details
- Business name (as registered with GST)
- GSTIN (all 15 digits)
- Business address (including state)
- Contact number and email
- Bank details for faster payments
Step 2: Set Up Invoice Numbering
- Start with a logical format: INV-001, INV-002, etc.
- Never skip numbers or repeat them
- Include the invoice date (important for GST records)
Step 3: Add Your Client's Details
- Full name/business name
- GSTIN (if they're registered)
- Address
- State (this determines if tax is SGST+CGST or IGST)
Step 4: Adjust GST Rates for Your Services
- Service providers: typically 18% GST (split as 9% SGST + 9% CGST)
- Some services: 12% or 5% (check GSTN list if unsure)
- Goods: rates vary from 0% to 28%
Step 5: Test the Calculations

- Check that taxes are calculated correctly
- Verify the total matches

Common Mistakes with GST Invoice Templates (And How to Avoid Them)
Mistake 1: Wrong GSTIN Format
Your GSTIN looks like: 27AABCT1234H1Z0
- 2 digits = State code
- 2 digits = Your PAN
- 1 digit = Check digit
Many freelancers enter it wrong. Copy-paste directly from your GST registration certificate.
Mistake 2: Mixing Up SGST and CGST
- SGST = State Goods and Services Tax (goes to your state)
- CGST = Central GST (goes to central government)
For 18% GST: It's 9% SGST + 9% CGST, not 18% on one line.
Wrong:
SGST @ 18%: ₹1,800
Total: ₹11,800
Correct:
SGST @ 9%: ₹900
CGST @ 9%: ₹900
Total: ₹11,800
Mistake 3: Missing Invoice Details
Every invoice needs:
- Unique invoice number
- Invoice date
- Your name/business name
- Client's name
- What you delivered (description matters—don't just write "Services")
Missing these = GSTN rejection.
Mistake 4: Ignoring SAC Codes
If you're doing professional services, you can't just ignore SAC codes. Use 998519 as your default (unless you're doing accounting, legal, or management consulting—which have specific codes).
Key Takeaway: These four mistakes account for 80% of invoice rejections—avoid them by using a properly built template.
How GST Invoices Affect Your Tax Filing
Understanding how your free GST invoice template connects to actual taxes is important.
ITC (Input Tax Credit) and Your Invoices
When you issue an invoice with proper GST breakdown, your client can claim ITC on the tax you charged them. This encourages clients to work with properly invoiced freelancers.
Example: You invoice ₹50,000 + ₹9,000 GST = ₹59,000 total.
Your client's accountant sees:
- Service cost: ₹50,000
- ITC they can claim: ₹9,000
This makes your invoices more valuable to business clients.
GSTR-1 and Your Invoices
Every month (or quarter, depending on your turnover), you file GSTR-1 (outward supply details). Your invoice details go here:
- Invoice number
- Invoice date
- Client GSTIN
- Taxable value
- Tax amount
Your invoice is the source document for this filing. If your invoice is incomplete, your GSTR-1 filing gets rejected.
This is why the free GST invoice template must be perfect from the start—it's not just about the client; it's about your compliance.
FAQ: Free GST Invoice Template India
1. Where can I find a free GST invoice template India?
The easiest way is to visit freeinvoicebill.com, which offers free, compliant templates in Excel and PDF. You can also find templates on the GSTN website, but they're less user-friendly.
2. Can I use a free GST invoice template if I'm not registered yet?
Yes, but only if you follow the unregistered format (no GSTIN, no GST rates). Once you're registered, switch to a GST-compliant free invoice template immediately.
3. What's the difference between SAC and HSN codes in a GST invoice template?
SAC (Service Accounting Code) is for services; HSN (Harmonized System of Nomenclature) is for goods. Freelancers typically use SAC code 998519 for generic professional services.
4. Do I need to show SGST and CGST separately on my invoice?
Yes. This is mandatory for GST-registered businesses. Even though SGST + CGST equals your total GST rate, they must be shown on separate lines in your free GST invoice template.
5. Can I edit a free GST invoice template I downloaded?
Absolutely. In fact, you must customize it with your business details, GSTIN, and client information. Just make sure you don't remove mandatory fields like HSN/SAC codes or tax breakdowns.
6. What if my client says my invoice format is wrong?
This is a red flag. Check:
- Is GSTIN visible and correct?
- Are SGST and CGST shown separately?
- Is the SAC/HSN code present?
- Does the tax calculation match?
If you've used a compliant free GST invoice template India, these should all be fine. Send them a copy of the template source (like freeinvoicebill.com).
7. Can I use the same free GST invoice template for all my clients?
Yes, but you must customize it for each invoice (client name, amount, date, invoice number). Never reuse invoice numbers—each invoice must be unique.
Bonus: Quick Checklist Before Sending Your Invoice
Before you hit send, verify:
- ✅ Your GSTIN is correct (15 digits)
