Your billing.
Set up for your trade.

Choose your industry.
Billing is ready.
A pharmacy does not bill like a garment shop. ZenBillOS starts from the way your business already works.
01
Choose your industry
Tell ZenBillOS what kind of business you run.
02
Get the setup for it
Billing arrives arranged for your trade, so you are not building it from nothing.
03
Start billing
Add your items as you go, and bill from the first day.
Ask your billing.
You make the final call.
Let it prepare the bill
Tell ZenBillOS what the customer is buying. It prepares the bill and shows you the preview before anything is saved.
- Draft
- Preview
- Approve
Ask about your business
Answers come from your own data, not a guess.
- How much did I sell last month?
- Which items sell the most?
- What is running low?
Preview first. Always.
ZenBillOS can create a bill and send it for you, but it shows you the preview and waits for your button. It never saves, sends or changes anything without your approval, and there is no way to skip that step.
e-invoice and e-way bill, from launch.
ZenBillOS connects through a GST Suvidha Provider (GSP) to generate your e-invoice with its IRN, and your e-way bill, without leaving the app.
GST rates and HSN codes come from a rule engine, not from the AI. When something is unclear, the bill is flagged for you to check. You stay responsible for the tax you file — ZenBillOS helps you get it right.
No signal? Keep billing.
Bills are written on your device first and sync when the network comes back. The AI features need an internet connection.
Phone, computer or browser.
The same app on Android, Windows and the web. Bill at the counter on your phone and see your reports on the computer. Your data never leaves India.
Free while we pilot.
Simple when we launch.
Example pricing, not final. ZenBillOS is free for everyone during the pilot.
