Features: GST Billing, Inventory & GSTR Returns

Billing & invoices

The till comes first: fast to use, correct to the paisa.

Quick Sale: The default screen. Scan or type a SKU to add a line, and repeat scans add to the quantity. Check out to a numbered invoice in a few keystrokes.
Tax Invoice or Bill of Supply: Picked automatically from your GST registration. Regular stores get the CGST/SGST/IGST breakdown and composition stores a Bill of Supply.
Right tax for the buyer's state: Place of supply comes from the buyer's GSTIN or state, switching between IGST and CGST+SGST. Rule 46 billing details are captured.
Generate Invoice: The full wholesale set: consignee, delivery note, dispatch details, buyer's order number, vehicle/LR number and custom orders with due dates.
Invoice series: Formats like RT/2026-27/Oct/001 with your choice of financial-year style. Separate series are supported, and past invoices are never renumbered.
Discounts and GST-inclusive prices: Enter a price inclusive of GST and the taxable value is worked out for you. Per-line discounts and extra charge lines such as delivery or packing are supported.
Modify, cancel, lock: Revise an invoice, cancel it with a reason (stock goes back), and track paid and unpaid bills. Completed invoices are locked.
Your brand on the page: Company logo, authorised signature image, bank details and amounts in words in the Indian lakh/crore system. Pages never spill onto an extra sheet.
Thermal receipts: Print a receipt at the counter and reprint a marked duplicate from Invoice History.
Payment modes: Cash plus any modes you add (UPI, card, bank), each posting to its own ledger. Record payments against unpaid bills later.

Inventory & purchases

Know what you have, where it came from and what it cost.

Products with variants: Size and colour variants under one product, each with its own SKU, stock and barcode. Products carry HSN codes and GST rates.
SKU auto-generation: SKUs built from name, colour and size (for example CLA-BLU-M-001), editable when you prefer your own.
Barcode label sheets: Code128 labels laid out to match precut A4 sticker stock (3 × 10, 64 × 27.5 mm).
Low-stock alerts: The dashboard flags low or negative stock and links straight to a new purchase entry.
Suppliers and purchase bills: Supplier details fill in automatically. Add a brand-new product, variant or category in the middle of a purchase.
Purchase trail: Every variant's stock is linked to the supplier bills behind it, and untrailed stock is flagged. Attaching a bill later never double-counts.
Safe price edits: Admins can change a product's price, HSN/SAC or GST rate. The change is audit-logged and past invoices keep what they were issued with.

GST returns

Prepared from the bills you already entered.

GSTR-1: B2B, B2C, credit/debit notes, HSN summary, nil-rated and document details, exported for the GST Offline Tool.
GSTR-3B and GSTR-1A: Summary return figures with notes netted in, ready to copy into the portal.
GSTR-2B / 2A reconciliation: Import the portal's statement and match it against your purchase register, including notes, to see missing or mismatched input tax credit.
GSTR-9: Annual return tables built from the year's books.
Composition: CMP-08 and GSTR-4: Quarterly statement and annual return for composition dealers.
Registers: Sales Register with GST, Purchase Register, Purchase Summary & HSN, and a Credit/Debit Note Register.

Accounting

Double-entry books in the style of Tally.

Ledgers that post themselves: Sales, purchases, receipts, payments and expenses post to the right ledgers as you work.
Vouchers: Journal, receipt and payment vouchers, plus credit and debit notes.
Statements: Trial Balance, Profit & Loss and Balance Sheet.
Debtors and creditors: Who owes you and whom you owe, with opening balances you can edit.
Fixed assets and investments: An asset register with depreciation, plus an investments ledger.
Quick expense entry: Record day-to-day cash expenses in seconds.
Excel export: Ledgers, registers and reports export to Excel for your accountant.

The installer takes a couple of minutes. Onboarding asks for your business details, GST type and an admin PIN, and then you're billing.
