What you get

Three services that work together, priced from the amounts below. Choose one or all three.

Billing & Invoicing System

from ₹25,000

GST tax invoices that print or save as PDF, with your customers, items and payments in one place.

  • CGST + SGST or IGST by place of supply, UTGST for union territories, round-off and the amount in words
  • Invoice numbers by financial year, like INV/2026-27/0001, that restart every 1 April
  • Customer records with GSTIN and state, items with HSN or SAC code and GST rate
  • Part or full payments, payment status, a ledger for every customer and a dashboard of billed, outstanding and overdue

Auto-invoicing

from ₹15,000

Invoices that make themselves for regular customers, with the PDF sent and the ledger updated.

  • A rule repeats the same invoice every month, two months, quarter, half year or year
  • The invoice PDF is sent to the customer and the customer ledger is updated
  • Payment reminders for late invoices, with a log of everything sent

Quotations & Estimates

from ₹12,000

Quotations in your own branding, checked by the owner before they go out, then one click to an invoice.

  • Your name, logo, colours and GSTIN on every quotation, printed as PDF
  • Approval step: the accountant sends it, the owner approves or rejects it
  • Convert an approved quotation into a GST invoice with the same lines

What the demo shows, and what it only pretends

So you know exactly what you are looking at.

Works in the demo

  • GST invoices with the tax split, round-off and amount in words
  • Quotations with an approval step and Convert to invoice
  • Printing any invoice or quotation to PDF from the browser
  • Payments, statuses (unpaid, partly paid, paid, overdue), customer ledger and dashboard
  • Auto-invoicing rules and payment reminders
  • Your own name, logo, colours and GSTIN; owner and accountant logins

Simulated in the demo

  • Sending an invoice, a quotation or a reminder: the demo only adds a line to a message log, marked demo
  • The payment link and the UPI QR on the invoice: both are fake on purpose and say so, so nobody can pay by mistake
  • Rules that run by themselves: in the demo you press Run, because a web page cannot run in the background

Names, GSTINs, HSN and SAC codes, GST rates and amounts in the demo are invented samples. E-invoicing (IRN), e-way bills and GST return filing are not part of the demo or of the menu prices. Tell us if you need them and we will say what is possible.

Frequently Asked Questions

How much does a billing and invoicing system cost?

The price depends on what you need. Prices start at ₹25,000 for Billing & Invoicing System, ₹15,000 for Auto-invoicing, ₹12,000 for Quotations & Estimates. We confirm the scope and a fixed price after you message us.

Can we try it before we decide?

Yes. A live demo is open at billing.groverhq.com. Enter a demo business code (one is a trader selling goods, the other a service business), then sign in as the owner or the accountant with one tap. It runs in your browser on sample data, so you can create a quotation, approve it, turn it into an invoice, record a payment and print the invoice without sharing any of your own information.

Does it handle GST correctly?

The invoice charges CGST and SGST when your state and the place of supply are the same, and IGST when they differ. Union territories without a legislature, such as Chandigarh, show UTGST. Each invoice shows the tax per line and per HSN or SAC code, the place of supply, whether reverse charge applies, the round-off to the rupee and the total in words. HSN or SAC codes and GST rates are set per item by you; the codes and rates in the demo are samples, so check yours with your accountant.

Does the demo really send invoices or take payments?

No. In the demo, sending an invoice, a quotation or a reminder only adds a line to a log marked demo, and the payment link and the UPI QR on the invoice are fake and labelled so. In a live setup sending and payments are connected to your own email, WhatsApp and payment account when your system is set up.

Can invoices carry our logo, colours and GSTIN?

Yes. The business name, logo, colours, address, GSTIN and terms are yours and appear on the app and on every printed invoice and quotation. The demo has a Branding screen where you can change them and see the result.

How does the quotation approval work?

A quotation starts as a draft and is sent for approval. The owner approves or rejects it; a rejected quotation can be corrected and sent again. Only an approved quotation can be converted to an invoice, and the invoice copies its lines and customer.

How are invoice numbers set?

By the Indian financial year, 1 April to 31 March, for example INV/2026-27/0001. The series continues through the year and starts again at 0001 on 1 April. Issued invoices are never deleted or renumbered.

What is not included?

E-invoicing (IRN), e-way bills and GST return filing are not part of the demo or of the menu prices. Tell us if you need them and we will say what is possible.
