Key Features of Our E-Invoicing Software

Zubizi's e-invoicing software handles the entire e-invoice lifecycle. From generating invoices to receiving IRN numbers, every step is automated and validated for GST compliance.

One-Click E-Invoice Generation via IRP

Create your invoice in Zubizi and click generate. The software transmits validated invoice data directly to the Invoice Registration Portal (IRP) via our authorized GSP integration. Your IRN and QR code are returned in seconds — no manual portal visits, no copy-pasting, no room for error.

Direct IRP connectivity via authorized GSP — no NIC portal login required
Auto-validation of GSTIN, HSN codes and tax rates before submission
IRN and QR code embedded automatically — invoice is IRP-compliant instantly

Automatic GSTN & HSN Validation

Before submitting to the IRP, Zubizi checks your GSTIN format, HSN code validity, tax rate classification (CGST/SGST vs. IGST), and all mandatory fields. Errors are caught and flagged before submission — not discovered after IRP rejection.

Bulk Invoice Processing

Validate and submit batches of B2B invoices to the IRP in a single operation. Essential for businesses approaching the 30-day reporting deadline — process hundreds of invoices in minutes, not hours of manual portal work.

IRN and QR Code Generation

Every e-invoice receives a unique Invoice Reference Number (IRN) — a 64-character hash from the IRP that is cryptographic proof of registration. Zubizi embeds the IRN and scannable QR code automatically. Your buyer needs this IRN to claim Input Tax Credit.

Error Prevention and Recovery

When the IRP returns an error code, Zubizi shows exactly what went wrong with specific instructions. Whether it's an invalid HSN code, a GSTIN mismatch, or a tax rate error — most corrections take seconds, and you resubmit immediately without starting over.

E-Way Bill + E-Invoice in One Click

From April 2025, B2B e-way bills cannot be generated without a valid IRN — meaning e-invoicing and e-way bill generation are linked. Zubizi handles both in a single submission: fill transport details once, and both documents are generated together at the IRP. No duplicate data entry, no missed compliance.

GSTR-1 Auto-Population

E-invoice data flows directly into your GSTR-1 return — no reconciliation, no manual re-entry. The IRP pushes your registered invoice data to GSTN's return system automatically. Zubizi tracks it and flags discrepancies before you file.

How to Generate E-Invoices

Getting started with e-invoice generation takes just a few steps:

1

Complete GSP Registration

Register with a GST Suvidha Provider to connect to the e-invoice portal. Zubizi guides you through this process in minutes.
2

Create Your Invoice

Enter invoice details in Zubizi as you normally would. Add customer info, items, quantities, and taxes.
3

Click Generate E-Invoice

Zubizi validates your data instantly and submits to GSTN. Any errors are flagged before submission.
4

Receive IRN and QR Code

GSTN returns your Invoice Reference Number within seconds. Your invoice is now legally valid and ready to share.

Why Your Business Needs E-Invoice Integration

Beyond meeting government requirements, automated e-invoicing transforms how you handle billing — saving time, eliminating errors, and giving you better control over your finances.

Stay GST Compliant Automatically

Non-compliance means penalties and audit troubles. With Zubizi, every invoice is validated against current GST rules before submission to the IRP. You do not need to track regulation changes yourself — we keep the system updated so your invoices always stay compliant.

Eliminate Manual Data Entry Errors

Typing the same invoice data into multiple systems leads to mistakes. Zubizi captures data once and uses it everywhere — no re-entry for GST returns, no copy-paste errors, no mismatched figures between your books and the IRP.

Speed Up Your Billing Process

Manual invoice processing takes hours that could go toward growing your business. With automated e-invoicing via IRP, what took an afternoon now takes minutes. Your team handles more B2B transactions without adding headcount.

Simplify GSTR-1 Return Filing

E-invoice data auto-populates your GSTR-1 returns. No more reconciling sales data manually. Zubizi tracks everything, matches it to your returns, and highlights discrepancies before filing. Monthly compliance becomes far simpler.

Protect Your Buyer's ITC Claims

Without a valid IRN on your invoice, your B2B buyer cannot claim Input Tax Credit. That makes your invoices a liability to them — and a reason to switch suppliers. Zubizi ensures every invoice has a valid, IRP-registered IRN before you share it.

Get Better Business Insights

When all invoices flow through one system, reporting becomes powerful. Track sales trends, monitor payment patterns, and analyze revenue by category. Zubizi turns your IRP-registered invoice data into actionable business intelligence.

Who Needs E-Invoicing Software?

E-invoicing is mandatory for businesses with annual B2B turnover above ₹5 crore. Even if you are below this threshold, getting set up now avoids disruption when the threshold lowers further.

₹5 Cr+ turnover → E-invoicing mandatory · ₹10 Cr+ → 30-day IRN reporting deadline applies

Retailers & Wholesalers

High B2B invoice volumes make IRP automation essential. Process bulk sales to distributors and dealers efficiently — without drowning in manual portal work.

Manufacturers

Complex supply chains need accurate documentation. E-invoicing via IRP ensures every step — from raw material purchase to finished goods dispatch — has a valid IRN.

Exporters

Export invoices have additional compliance requirements. Zubizi handles export invoice formatting, SEZ supplies, and the e-invoice registration with proper documentation.

Frequently Asked Questions

Common questions about e-invoicing software for Indian businesses.

What is e-invoicing software and why do I need it?

E-invoicing software automates the process of generating GST-compliant electronic invoices and submitting them to the government portal. If your business has annual turnover above Rs. 5 crore, e-invoicing is mandatory for B2B transactions. The software eliminates manual portal work and ensures compliance without errors.

Is e-invoicing mandatory for my business?

E-invoicing is mandatory for businesses with aggregate annual turnover exceeding Rs. 5 crore for B2B transactions. The threshold has been progressively lowered, so even smaller businesses should prepare. From April 2025, businesses with Rs. 10 crore+ turnover must upload e-invoices within 30 days of issuance.

How does Zubizi's e-invoicing software connect to GSTN?

Zubizi connects to the GSTN e-invoice portal through authorized GST Suvidha Providers (GSP). When you generate an invoice, the software validates your data and submits it directly to the Invoice Registration Portal. The IRN and QR code are returned within seconds.

Can I generate e-invoices in bulk?

Yes, Zubizi supports bulk e-invoice generation. Upload multiple invoices, validate them together, and submit to GSTN in a single operation. This is essential for businesses processing hundreds of B2B invoices monthly.

What happens if my e-invoice gets rejected?

Zubizi validates invoice data before submission, catching most errors. If GSTN still rejects an invoice, the software shows the exact error with clear instructions to fix it. Most corrections take seconds, and you can resubmit immediately without starting over.

Is Zubizi's e-invoicing software integrated with accounting?

Yes, e-invoicing in Zubizi is fully integrated with billing, inventory, and accounting. Invoice data flows directly to your ledgers and GST returns. There is no need for separate software or manual data transfer between systems.

Can I generate e-way bills along with e-invoices?

Absolutely. When your invoice requires transport documentation, fill in vehicle and transporter details before generating. Zubizi submits both e-invoice and e-way bill to the government portal in one operation, saving time and avoiding duplicate data entry.

What information is included in an e-invoice?

An e-invoice includes the Invoice Reference Number (IRN), QR code, acknowledgment number, and date from GSTN. All standard invoice details like supplier and buyer GSTIN, item details, HSN codes, and tax breakup are also included as per government requirements.

How do I get started with e-invoicing in Zubizi?

First, complete GSP registration through Zubizi. We guide you through the process. Once registered, create invoices as usual and click generate to submit to GSTN. The entire setup typically takes one day, and you can start generating compliant e-invoices immediately.

Can I cancel an e-invoice after generation?

You can cancel an e-invoice within 24 hours of generation through the software. After 24 hours, cancellation is not allowed. You will need to issue a Credit Note instead. This is a government regulation, not a software limitation.

Does Zubizi work offline for e-invoicing?

E-invoice generation requires internet connectivity since invoices must be submitted to GSTN in real-time. However, you can create and save invoices offline, then generate e-invoices when connected. Your invoice data is always available locally.

What GST document types does the e-invoicing software support?

Zubizi supports all GST-compliant document types including Tax Invoices, Credit Notes, and Debit Notes. For each document type, the software handles the correct format and validation rules required by GSTN.

Is my e-invoice data secure?

Yes, all communication with GSTN uses encrypted connections. Invoice records are stored securely with proper access controls. We follow Indian data protection standards, and your financial information remains confidential throughout the process.

What support is available if I face issues?

When you need help, you connect with real people who built this software. Our team understands e-invoicing inside out and can resolve issues quickly. We also maintain a detailed knowledge base with error solutions and step-by-step guides.

What is the 30-day e-invoice reporting rule?

As of April 1, 2025, businesses with annual aggregate turnover of Rs. 10 crore or more must generate an IRN within 30 days of the invoice date. If the deadline passes, the Invoice Registration Portal (IRP) will block IRN generation for that invoice — making it legally invalid for your buyer's ITC claim. Zubizi tracks invoice dates and alerts you before the 30-day deadline so you never miss it.

Does Zubizi support multiple GSTINs for e-invoicing?

Yes. If your business operates under multiple GSTINs across different states or branches, each GSTIN can be registered and managed separately in Zubizi. E-invoicing is handled independently per GSTIN, ensuring compliance for all your business locations. Contact our team to set up multi-GSTIN e-invoicing for your business.

What exactly is an IRN and why does my buyer need it?

An IRN (Invoice Reference Number) is a unique 64-character hash generated by the government's Invoice Registration Portal (IRP) for each e-invoice. It is cryptographic proof that your invoice was officially registered with GSTN. Your B2B buyer needs a valid IRN on your invoice to legally claim Input Tax Credit (ITC). Without IRN, the invoice is considered invalid for GST purposes — which means your buyer absorbs the tax cost and will likely stop purchasing from you.
