Invoice GST invoicing for every company you run.
Raise proforma and tax invoices, record payments against them, and hand the NIC portal the exact e-invoice and e-way bill JSON it wants — across all your companies and GSTINs, from one login.

The whole invoice lifecycle, not just the PDF.
From the first proforma to the last payment, every document is built from the same masters and the same tax engine, so numbers agree everywhere — on the PDF, in the portal JSON and in your reports.
Many companies, many GSTINs
One login can belong to several companies, and each company can bill from several GSTINs with their own numbering series and bank details. Switch from the top bar.
Every GST document
Proforma invoices that convert into tax invoices, plus credit and debit notes. Place of supply picks CGST + SGST or IGST, and round-off is handled for you.
Masters you set up once
Customers with billing and delivery addresses, products with HSN/SAC and rates, banks and transporters. Issued documents keep a frozen copy, so editing a customer never changes an old invoice.
Payments & receivables
Map each payment against one or more invoices and see what's outstanding by customer, with receivable and GST reports that export to Excel.
E-invoice & e-way bill JSON
Export invoices in the NIC schema for the e-invoice and e-way bill offline tools, then upload the returned IRN and EWB details back — they print on the PDF with the signed QR.
Your team, with roles
Invite teammates by email and give each a role with per-module permissions — view, create, edit, issue — so the right people can do the right things.
From proforma to paid in four steps.
Quote with a proforma
Pick a customer and products; GST, totals and amount in words are worked out as you type.
Convert to a tax invoice
One step carries the lines across and takes the next number from the series for that GSTIN and financial year.
Portal JSON & PDF
Export e-invoice / e-way bill JSON for the NIC tools, upload the IRN and EWB back, and share the final PDF.
Record the payment
Map receipts against invoices; receivables and GST reports update straight away.
Invoices the portal and your CA will accept.
Indian GST has rules that a generic invoice template doesn't know about. Invoice Partner bakes them in.
Intra-state supplies split into CGST + SGST, inter-state into IGST, from the state codes on your GSTIN and the buyer's address.
Numbers reset with the financial year and never collide, even with two people raising invoices at the same moment.
Once issued, a document keeps its own copy of seller, buyer, address and product details. Corrections go through credit and debit notes, as GST expects.
E-invoice and e-way bill JSON is checked against the portal's schema before you download it, so the offline tool doesn't bounce it.
Your data, in plain words
Invoice Partner stores your company's masters and documents so it can run, and nothing goes to advertisers or analytics SDKs. Data travels over HTTPS, passwords are hashed with bcrypt, and sessions use short-lived tokens you can sign out of everywhere at once. Your company owns its data; we process it on your behalf.

The iOS and Android app is the on-the-go companion to the web: raise tax invoices and proforma invoices, save drafts, and share the PDF before you leave. Masters, reports and portal work stay on the web.

Straight answers.
What people ask before moving their invoicing over.
Does Invoice Partner file my e-invoices or e-way bills with the portal?
Not directly. It generates JSON in the NIC schema for the e-invoice and e-way bill offline bulk tools. You upload that file on the portal yourself, then bring the returned IRN, acknowledgement and EWB details back into Invoice Partner, which prints them and the signed QR on the invoice PDF.
Can I run more than one company or GSTIN?
Yes. One login can belong to many companies, and each company can hold several billing GSTINs with their own numbering series. Switch between companies from the top bar on the web or in the app.
Can my team use it too?
Yes. Invite teammates by email and give each one a role. Roles carry per-module permissions, so an accountant can record payments without being able to change masters, for example.
What does the mobile app do?
It raises tax invoices and proforma invoices from any of your GSTINs and series, works out GST and round-off, saves drafts, and shares the invoice PDF on WhatsApp, email or any app. Masters, reports, e-invoice and e-way bill work stay on the web.
Who owns the invoice data?
Your company does. Invoice Partner stores it to run the service, never sells it, and doesn't share it with advertisers or analytics SDKs. Lists and reports export to Excel.
Is Invoice Partner free?
Yes. Invoice Partner is free to use today. If paid plans are ever introduced, company owners get at least 30 days' notice and nothing is charged without their agreement.
Is there an Invoice Partner app for iOS and Android?
Yes. The iOS and Android apps are in testing. They use the same account and data as the web app, which is live now.
Who built Invoice Partner, and why?
Shreyansh Jain built it for his father, who was running his invoicing from a Google Sheet with no reports, no view of who still owed him, and every e-way bill typed out by hand. It started as his tool and is open to anyone billing the same way.
How do I delete my account?
Email shreyansh@shrynshjn.com from the address on your account and ask for it to be deleted. The privacy policy explains what is removed and what has to be kept for tax-record reasons.
My dad ran his invoicing out of a Google Sheet — no reports, no way to see who still owed him, and every e-way bill typed out by hand. He wanted something better, and I could build it, so I did. Invoice Partner started as his tool; it's open to anyone billing the same way.
I've also built Money Manager and SSH Connect, plus a few other apps — see everything I've made.
