Please note: Billing Studio makes GST documents and summaries. It does not file returns and gives no tax advice: check rates and returns with your CA.

The problem

Billing should not take your evening

Invoices typed in Word or Excel, with the GST worked out by hand and a total that sometimes does not match.
Inter-state or intra-state, which rate, which HSN: one mistake and the client sends the bill back.
Who has paid, who is late and what to give the CA at the end of the month is spread across papers and chats.

The answer

Billing Studio

Billing Studio does the GST maths, numbers every document in order, makes the PDF and keeps track of what is paid, so a bill takes a minute and the month-end summary is one click.

Inside the product

Real screens. Real features.

Every picture below is a screen from Billing Studio with its demo data. Click one to see it full size.

New invoice

Tap your items, the totals follow

Pick the client, tap the items you sell and the quantities; the taxable value, CGST and SGST or IGST, discount and round-off are worked out as you go.

Place of supply decides CGST + SGST or IGST
Your items and clients are remembered for next time
Terms of sale in one tap: delivery, payment, warranty

The PDF

A tax invoice your clients take seriously

Your logo, GSTIN, the client's GSTIN and state, HSN or SAC per line, the amount in words and a tax summary, on one clean page.

Several styles and your own colour
Bank details and a UPI QR code to get paid faster
Original for recipient, numbered by financial year

GST done right

Mixed rates, cess, discounts and other states

Several rates on one bill, cess on top, a discount on some lines, a client in another state: each line is taxed correctly and the tax summary adds it up by rate.

Every GST rate, 40% included, plus cess
IGST for clients in other states
GSTIN checked as you type it

Quotations

From quotation to invoice in one click

Send a quotation or a proforma invoice, mark it accepted or declined, and convert the accepted one into a tax invoice without typing it again.

Valid-until dates and follow-ups
Drafts get a number only when you approve them
Every step kept in a permanent history

Notes and challans

Credit notes, debit notes and delivery challans

Made from the invoice they belong to, so returns, extra charges and goods sent without a bill are always linked and numbered.

One click from the invoice
Credit notes are taken off your sales totals
Cancelled numbers are never reused

Questions

Good to know

Is there a monthly or yearly fee?

No. You pay once and keep using it. There is no account to create.

Does it work without the internet?

Yes. Making documents, PDFs, reports and backups all work offline. The internet is used only when you send an email or open WhatsApp.

Can it make e-invoices (IRN) or file my GST returns?

Not yet. Billing Studio makes your GST documents and the summaries for returns; your CA files them using the sales register and the GST and HSN summary it gives you. If your turnover needs e-invoicing, please wait for a later version.

Where is my data kept?

In your Documents folder, under Billing Studio: every PDF named by its number and client, the records, and a backup made every day (the last 30 are kept). Copy the Backups folder to a pen drive or Google Drive for extra safety.

Does it work on a Mac?

Not yet. Billing Studio runs on Windows 10 and 11 (64-bit). A Mac version will be listed here when it is ready.

Windows says "Windows protected your PC". Is that normal?

Yes, the first time you open it, because the app is not code-signed yet. Click More info, then Run anyway.

Why is the price different in my country?

Prices are set for each region so people everywhere can afford them. The price you see is for the country where you live and pay from. The India price can be paid only with Indian payment methods (UPI, Indian cards and netbanking).

How do I get my files?

Right after payment the download button appears on the thank-you page, and your receipt email has a button that gets your files again later. Each purchase includes up to 10 downloads.

Can I get a refund?

Our products are digital and delivered instantly, so once a product is delivered it is not refunded. If something is wrong with the product, we fix it or replace it, and if we cannot do either within 14 days of your request, we refund you. If your payment went wrong (money taken but no order, or charged twice), we refund it. Your legal rights in your country always apply. See the Refund Policy for the details.

Which payment methods can I use?

Payments are handled by Razorpay: cards, UPI, netbanking and wallets in India, and international cards elsewhere. We never see or store your card details.

Still unsure? Write to us. We reply within 2 working days.
