START HERE

Create your first invoice

Go from first launch to a professional GST invoice in five steps.

  1. 01

    Set up your business

    Open Settings and enter the business name, GSTIN, PAN, address, seller state and bank details. Upload a PNG or JPEG logo for printed documents.

  2. 02

    Add customers and suppliers

    Save party names, GSTINs, addresses and states. A customer’s state determines the place of supply used for sales tax.

  3. 03

    Build the product catalog

    Add goods, raw materials or services with HSN/SAC, unit, selling price and GST rate. Add barcodes and reorder levels when stock tracking is required.

  4. 04

    Create and finalize an invoice

    Choose a customer, add products, review discounts and tax, then save a draft. Finalize it when the details are correct so it feeds stock and reports.

  5. 05

    Print, export or share

    Generate an A4 PDF, print it, open its folder, copy the path or prepare sharing through WhatsApp, SMS or email.

Set the seller state first. It is required for automatic intra-state and inter-state GST treatment.

AUTOMATIC TAX TREATMENT

How GST is calculated

InvoiceGST compares the seller state in Settings with the customer state on the invoice.

Supply typeConditionTax applied
Intra-stateCustomer state matches seller stateCGST + SGST
Inter-stateCustomer state differs from seller stateIGST

Taxable values and tax amounts are calculated per line and rounded to two decimal places. Confirm your setup and exported figures with your accountant before filing.

LOCAL BY DESIGN

Your data and backups

InvoiceGST stores business records in a local SQLite database and does not require a cloud database for daily work.

Database

Find the exact location in Settings → Backup & restore. On Linux it is typically:

~/.local/share/invoicegst/InvoiceGST/invoicegst.db

PDF documents

Exported PDFs are normally saved in your Documents folder:

Documents/InvoiceGST/

Back up regularly. Create a database backup before reinstalling the operating system, moving computers or restoring older data.

QUICK ANSWERS

Common questions

Does InvoiceGST work without internet?

Yes. Daily billing and business data stay in a local SQLite database. Internet access is useful for downloading, purchasing, support and external share links.

What happens after the 30-day trial?

You can continue opening existing data. Creating or saving billing documents and generating print/PDF output requires an activated license.

Can I move the app to another computer?

Create a database backup first. Deactivate the license on the current PC, install InvoiceGST on the new computer, restore the database and activate your key.

Does InvoiceGST file GST returns directly?

InvoiceGST generates GSTR-1 and HSN helper exports for review. Check the files with your accountant and use the official filing process appropriate for your business.
