Create Your Business

When you sign in to Hisaabo for the first time, you are prompted to create a business. This page explains each setting so you configure it correctly from the start. Getting the GST state code right is especially important — it drives automatic CGST/SGST versus IGST calculation on every invoice.

Step 1: Basic details

Field	Required	What to enter
Business Name	Yes	Your trading name, for example “Sharma Electronics”
Legal Name	No	Your full registered legal name if different from the trading name
PAN	Yes	Your 10-character Permanent Account Number
Phone	Yes	Your primary business phone number
Email	No	Your business email address
Address	Yes	Your full business address

Step 2: State and state code

Beyond the address (entered above), the state and state code fields deserve special attention.

State: Enter your full state name, for example “Maharashtra” or “Tamil Nadu”.

State Code: Enter the 2-digit GST state code for your state. This is the most critical configuration value in Hisaabo. The system uses this code to determine whether a supply to a party is intra-state (same state code → CGST + SGST) or inter-state (different state code → IGST).

Common GST state codes:

State	Code	State	Code
Jammu & Kashmir	01	Himachal Pradesh	02
Punjab	03	Chandigarh	04
Uttarakhand	05	Haryana	06
Delhi	07	Rajasthan	08
Uttar Pradesh	09	Bihar	10
Sikkim	11	Arunachal Pradesh	12
Nagaland	13	Manipur	14
Mizoram	15	Tripura	16
Meghalaya	17	Assam	18
West Bengal	19	Jharkhand	20
Odisha	21	Chhattisgarh	22
Madhya Pradesh	23	Gujarat	24
Maharashtra	27	Karnataka	29
Goa	30	Kerala	32
Tamil Nadu	33	Telangana	36
Andhra Pradesh	37

Tip

Your state code is printed on your GSTIN — it is the first two digits. For example, if your GSTIN is 27AABCU9603R1ZX, your state code is 27 (Maharashtra).

Step 3: GST registration

Choose your registration type:

Type	When to choose
Regular	Your business is GST registered with a GSTIN. You collect and file GST.
Composition	You are enrolled in the GST Composition Scheme (small taxpayer, simpler filing).
Unregistered	Your business is below the GST threshold and not registered.

If you select Regular or Composition, enter your GSTIN (15-character GST Identification Number). Your PAN (10-character) is already required in the basic details above and is used for all registration types.

Note

Non-GST businesses (Unregistered) can still use all invoicing features. The GST columns simply show zero tax, and GSTR-1/GSTR-3B reports show generic totals rather than GST-specific breakdowns.

Step 4: Invoice numbering

Configure how invoice numbers are generated for each document type:

Setting	Default	Example
Invoice prefix	INV	INV-00001
Payment prefix	PAY	PAY-00001
Quotation prefix	QTN	QTN-00001
Credit note prefix	CN	CN-00001
Delivery challan prefix	DC	DC-00001
Proforma prefix	PI	PI-00001

Invoice numbers are assigned sequentially and atomically — the counter increments inside a database transaction so you never get a duplicate number even under concurrent load.

Tip

If you are migrating from another app and want invoice numbers to continue from where they left off, set Next invoice number to your last used number plus one. For example, if your last invoice was INV-00847, set the next number to 848.

Step 5: Financial year

Financial year start month defaults to April (month 4), which is the standard for Indian businesses. The dashboard “this financial year” summaries count from the 1st of this month in the current or previous calendar year.

If your business uses a calendar year (January to December), set this to 1. January.

After creating your business

Once you save, you will land on the dashboard. Your next steps are:

1. Add your parties — import from MyBillBook or add customers and suppliers manually. See Parties.
2. Add your items — create the products and services you sell or buy. See Items & Inventory.
3. Create your first invoice — See Create an Invoice.

Managing multiple businesses

You can create additional businesses from the business switcher in the navigation bar. Each business has completely separate data — parties, items, invoices, and settings are not shared between businesses.

Frequently asked questions

I entered the wrong state code. How do I fix it? Go to Settings and edit your business profile. Update the state code and save. The change takes effect immediately on all future invoices. Existing invoices are not affected.

Can I change my invoice prefix after I have already created invoices? Yes, but the counter continues from where it left off. Changing the prefix does not reset the counter. For example, if you have 50 invoices with prefix INV, changing to BILL will produce BILL-00051 as the next invoice.

What if my party is in a Union Territory? Union Territories have their own GST codes (for example, Delhi is 07, Puducherry is 34, Dadra & Nagar Haveli and Daman & Diu is 26). Enter the correct 2-digit code for the territory. The CGST/UGST (Union Territory GST) split works the same as CGST/SGST for Hisaabo’s calculation purposes.
