Bills built in Excel or Word
Last month's file is copied and edited. Numbers repeat or skip, and a GST rate gets typed wrong.
INV-118 is missing, INV-119 appears twice, and your CA asks why when the return is due.

What is billing software?
Billing software creates bills for what you sell, works out the tax, sends them to your customers and keeps track of what has been paid. Good billing software also numbers every bill in sequence, records payments and part payments, and reminds customers when a bill is due.
In PikZiy Books, billing is connected to everything else. A bill updates your customer's balance on its own, and feeds your GST returns (Growth plan and above) and your double-entry books (Business plan and above).
WHY BUSINESSES SWITCH
Where billing usually goes wrong.
Payments tracked from memory
Money arrives by UPI, bank transfer and cheque, sometimes in parts, and none of it is matched to a bill.
A client pays ₹40,000 of a ₹59,000 bill. Three weeks later, nobody remembers the ₹19,000.
GST pieced together at month end
Sales are collected from three places and rates checked by hand before GSTR-1 can be filed.
One inter-state bill was charged CGST + SGST instead of IGST, and has to be corrected with a credit note.
HOW IT WORKS
From customer to cash, in four steps.
These are screenshots of the real app with a sample business, Ember & Oak Studio in Pune.
- 01
Add your customer once
Save each customer with their GSTIN, state, billing and shipping addresses and contacts. Every bill, payment and reminder for them is then in one place.
- Business or individual customers
- Several addresses, emails and phone numbers
- Everything you have billed them, and what they still owe
- 02
Create the bill
Pick saved items with their HSN or SAC code and price, or type a new line. Choose the tax on each line, add a discount, notes and your bank or UPI details.
- CGST, SGST, IGST and cess on each line
- A warning when the tax does not match your customer's state
- A number from your own series, given when you issue the bill
- 03
Send it, and let them pay
Email it from PikZiy Books, share its private link on WhatsApp, or download the PDF. Your customer opens it without an account and can pay online.
- UPI, cards and net banking through your own Razorpay, Cashfree or Easebuzz account
- Download PDF on the customer's side too
- You can see when they have opened it
- 04
Know who has paid
Record full or part payments, with a numbered receipt for each. Every bill shows where it stands, and reminders go out by email on the schedule you choose.
- Unpaid, Partly paid, Overdue and Paid at a glance
- TDS your customer kept back, recorded with the payment
- Reminders stop when the bill is paid

WHAT YOU GET
Everything a bill needs, and what comes after.
GST bills, quotes and credit notes
CGST, SGST, IGST and cess on each line, with HSN or SAC codes, discounts and notes.
Your own number series
Prefixes such as INV- or QT-. Drafts have no number; each bill takes the next one when you issue it.
A private link for every bill
Your customer views, downloads and pays without signing up, and you see when they have opened it.
Online payments, no cut
Money goes straight to your own Razorpay, Cashfree or Easebuzz account. We never hold it.
Payments and receipts
Full or part payments by any method, TDS kept back, and a numbered receipt for every payment.
Automatic reminders
Polite emails before and after the due date, on a schedule you set, from your own templates.
Goods and stock
Items with stock levels and low-stock alerts, so you know what you can still sell.
Bills in other currencies
Bill clients abroad in dollars, euros, pounds and more. Your books record the rupee value at the rate you enter.
Customer statements

Business plan and aboveSubscriptions

Business plan and aboveGST returns from your bills

Growth plan and aboveCollections

Growth plan and aboveBILL ONCE
The books do the rest.
Many billing apps stop at the bill. In PikZiy Books, issuing a bill and recording its payment also posts balanced double-entry entries to your books, from a start date you choose, on the Business plan and above.
Your profit and loss, balance sheet, customer ledgers and GST worksheets are built from the same records, so your CA starts from clean books instead of a spreadsheet. See every feature.

QUESTIONS
Asked, and answered.
What is billing software?
Billing software creates bills (invoices) for what you sell, works out the tax, sends them to your customers and keeps track of what has been paid. Online billing software does this in your browser, so your bills are the same on every device and you can share access with your team or your CA.
Which is the best billing software for a small business in India?
The one that fits your kind of business. Service businesses need quotes, payment tracking and reminders; shops and traders need fast billing and stock; growing teams need roles and an audit trail. Our guide to choosing accounting software compares the main options fairly, and what billing software costs in India sets out real prices.
Can I create GST bills with PikZiy Books?
Yes. Bills show your GSTIN and your customer's, HSN or SAC codes, and CGST and SGST, or IGST, on each line, with cess where it applies. They are numbered in sequence with your own prefix. You choose the tax on each line, and PikZiy Books warns you if CGST + SGST or IGST does not match the state your customer is in. Our GST invoice format guide lists the fields the rules ask for.
Can I use it if my business is not registered for GST?
Yes. Leave GST off the lines and the bill carries no tax. See how to invoice without GST registration for what such a bill should say.
How do my customers pay a bill?
Each bill has a private link your customer can open without an account. If you connect Razorpay, Cashfree or Easebuzz, they can pay online by UPI, card or net banking, and the money goes straight to your own account. They can also pay you directly by bank transfer or UPI, and tell you they have paid with proof of payment, which you then record.
Does PikZiy Books take a cut of my payments?
No. We never hold your money and add no fee. Your payment provider charges its own fees and pays out to your bank account.
Can I record part payments, advances and TDS?
Yes. Record any amount by bank transfer, UPI, cash, card or cheque, each with a numbered receipt. If your customer keeps back TDS, record it with the payment and the bill is settled, with the TDS kept aside to claim against your income tax.
Can I bill for goods and keep track of stock?
Yes. Items can be goods or services, with stock levels and low-stock alerts on every plan. Purchase orders, goods received notes and supplier bills are on the Business plan and above.
Can my accountant or my team use it?
Yes. Invite people as owners, admins, accountants, staff or viewers; each sees and changes only what their role allows. Your CA can work directly in your books as a team member. See PikZiy Books for accountants.
Does it work on my phone?
Yes. PikZiy Books runs in the web browser on a phone, tablet or computer, so there is nothing to install. Your customers open their bills in their own browser too.
How much does PikZiy Books cost?
There are four plans, from Starter for one person to Enterprise for teams of 25. Plans differ by features and team size, never by how many bills you send, and every plan starts with a 14-day free trial. Prices are published when sign-ups open in November 2026. Businesses that sign up from 1 November 2026 to 30 April 2027 and pay for a year get 18 months for the price of 12. See plans.
