Inventory SoftwareGST Billing & Inventory Software in One System
Raise GST invoices from the same stock you manage. NexoraIMS calculates CGST, SGST or IGST from place of supply, freezes tax at posting, handles credit notes and exports, and tracks GSTR-1 and GSTR-3B by month. It is GST-ready; keep your CA in the loop.

Why Billing and Inventory Belong Together
When billing and stock are separate, every sale is typed twice or reconciled later. Items get sold that are not in stock, returns do not restore stock, and nobody can compute margin because cost is in a different system.
In NexoraIMS posting an invoice issues stock and fixes the tax in one action. A credit note reverses goods and tax in proportion. Gross margin is available because the cost of each sale comes from the same ledger.
GST Billing Features
GST invoices
CGST+SGST for intra-state, IGST for inter-state, HSN/SAC, place of supply from the invoice or customer state.
Credit notes
Linked to the invoice, reversing goods, freight and reverse-charge tax in proportion; the final return settles rounding.
Export and SEZ
Exports use place of supply 96 and IGST; SEZ and export under LUT are zero-rated; foreign-currency export invoices convert at your rate.
GSTIN and checks
GSTIN validation and a GST reconciliation check compare every invoice header with its lines and charges.
GST returns tracker
GSTR-1 and GSTR-3B by month with due dates, output tax, ITC and net payable; mark reviewed and filed with ARN. It does not connect to the GST portal.
Print and share
Document designer layouts, A4/A5, and e-mail or WhatsApp links that open a read-only copy without login.
GST Returns Tracker
The GST returns page lists each month's GSTR-1 (due the 11th) and GSTR-3B (due the 20th of the next month) with output tax less credit notes, input tax credit and net payable. After the month ends press Mark reviewed; after filing on the portal press Mark filed and enter the 15-character ARN and date.
If invoices change after a review, a warning shows the new figures, and a daily notification flags late and soon-due returns. Figures are estimates to help your accountant; they are not a substitute for filing on the GST portal.
