Features
Everything that makes GST billing tedious, handled
The parts that matter most are the ones nobody notices when they work: figures that tie out, numbers that do not skip, and documents that stay what they were on the day you issued them.
GST invoicing
- Automatic tax split
- Place of supply decides CGST and SGST versus IGST. Total tax is identical either way; only the split changes, and we apply the right one.
- Every rate slab
- 0%, 0.25%, 3%, 5%, 12%, 18% and 28%, plus cess where it applies. A single invoice can mix rates and the per-rate summary still reconciles to the total.
- Inclusive or exclusive pricing
- Enter MRP-style rates that already contain GST and the tax is worked backwards, landing exactly on the price you typed.
- Reverse charge
- Tax is reported on the invoice but excluded from the amount payable, since the recipient deposits it.
- Round-off and amount in words
- Rounded to the nearest rupee with the difference recorded, and the total spelled out in the Indian numbering system.
Documents
- Ten document types
- Tax invoice, proforma, quotation, estimate, purchase order, delivery challan, credit note, debit note, payment receipt, and non-GST invoice.
- Independent numbering series
- Each type gets its own gapless series per financial year, allocated when the document is saved so two users cannot collide.
- Drafts, edits, duplicates
- Prepare work as a draft without consuming your monthly quota, then issue it. Duplicating an invoice starts a fresh draft.
- Print, PDF, email, WhatsApp
- A print-ready A4 sheet, a PDF through your browser, email to the customer, or a WhatsApp share link with the amount and a view link.
Customers and items
- GSTIN validation
- Structure and the official mod-36 checksum are both checked, and the state code is read out of the GSTIN to prefill place of supply.
- Invoices stay fixed
- Names, addresses, and HSN codes are copied onto each document. Editing a customer later never rewrites something you already issued.
- HSN and SAC codes
- Stored per item and carried onto every line, feeding the HSN summary you need at filing time.
- Outstanding balances
- Per-customer totals for what has been billed and what is still owed, with the full document history.
Inventory and payments
- A stock ledger that reconciles
- Opening stock, sales, purchases, and adjustments each write a movement alongside the balance change, in one transaction.
- Low-stock alerts
- Set an alert level per item and see what has fallen below it on the dashboard.
- Seven payment methods
- Cash, bank transfer, UPI, credit card, debit card, cheque, and online — each with a reference field.
- Part payments
- Record any amount up to the balance. Invoice status follows the numbers automatically rather than being set by hand.
Reports
- GST summary
- Taxable value and output tax by head for any date range, suitable for cross-checking GSTR-1.
- HSN and SAC summary
- Quantity, taxable value, and tax grouped by code and rate.
- Customer and item analysis
- Who owes you the most, and which items bring in the most value.
- CSV export
- A GSTR-1-shaped export with a totals row, UTF-8 with a byte-order mark so Excel opens it correctly.
Security and access
- Role-based staff access
- Grant specific permissions — invoices, customers, products, payments, reports, settings — per staff member.
- Tenant isolation
- Every query is scoped to a business you belong to, checked server-side rather than trusting anything the browser sends.
- Sessions in httpOnly cookies
- Signed JWTs that JavaScript cannot read, with passwords hashed using bcrypt.
- Multiple businesses
- Run several businesses under one login and switch between them without signing out.
