What it is
Billing is easy. GST billing has rules.
Under GST, a bill is not just a receipt. It is a tax document. It must carry your GSTIN, a serial number that never repeats within the year, the HSN code of each item, the right tax rate and the correct split between central and state tax. If the customer is registered, their GSTIN goes on it too, because they will claim credit on it.
Get any of this wrong and the trouble shows up later: your customer can’t claim credit, your GSTR-1 doesn’t match their records, or your CA spends hours fixing figures before the return is due.
Milaan ERP takes care of the rules while you bill. Each item carries its HSN code and rate. The customer’s GSTIN tells the software whether to charge CGST and SGST or IGST. Bill numbers run in order. E-invoice and e-way bill details come from the bill when they are needed. And every bill lands in your GSTR-1 and GSTR-3B figures without anyone typing it again.
It works the same whether you run a small shop, a wholesale business or a factory.
Common GST billing mistakes
Where GST bills usually go wrong, and how we prevent it
These are the mistakes CAs tell us they fix most often for their clients.
-
Wrong tax type
IGST charged on a local sale, or CGST and SGST on an out-of-state sale. The customer can’t use the credit.
Tax type from place of supply
The software compares your state with the customer’s place of supply and picks the right tax every time.
-
Missing or wrong HSN codes
Items are billed without HSN codes, or with codes that don’t match the rate.
HSN and rate on every item
Set the HSN code and rate once per item. Every bill carries them.
-
Gaps in bill numbers
Bills are deleted or numbered by hand, leaving gaps that raise questions in an audit.
Numbering that runs in order
Bill numbers follow your series automatically. Cancelled bills stay on record as cancelled.
-
Returns built from scratch
Every month, someone collects bills and types totals into the return.
Returns built as you bill
GSTR-1 and GSTR-3B figures add up as you work, ready to export.

What the law asks
What every GST invoice must show
The GST invoice rules (Rule 46 of the CGST Rules) list what a tax invoice must contain. The most important ones are shown on the right. For inter-state sales, the place of supply and the state name must also be shown, and the bill must say whether tax is payable on reverse charge.
Milaan ERP’s invoice formats include all of these fields, so every bill you print or send is a valid tax invoice.
Tip: GST rules change from time to time. This page explains them in simple words; for advice on your own case, please speak to your CA.

Talk to our team
We’ll show you GST billing using your own items and customers.
Does Milaan ERP choose between CGST/SGST and IGST automatically?
Yes. It compares your state with the customer’s place of supply. Sales within your state get CGST and SGST; sales to another state get IGST.
Do I need to know HSN codes?
You set the HSN code and rate once for each item. Our team helps with common codes during setup, and your CA can check them.
Can I make bills for unregistered customers?
Yes. Bills to customers without a GSTIN are recorded as B2C sales and go into the right part of your GSTR-1.
Does it support e-invoicing and e-way bills?
Yes. Details for both come from the bill itself, so nothing is typed twice.
Can my CA get the data directly?
Yes. Export GSTR-1 data, GSTR-3B summaries and other reports, or give your CA a read-only login.
What if a GST rate changes?
Update the rate on the item. New bills use the new rate; old bills stay as they were.
How much does Milaan ERP cost?
