The GST Engine

Tax logic that knows the rules, so you don't have to remember them.

Every invoice is checked against the place of supply, the item's HSN, and your GSTIN — then split into the right heads automatically. Intra-state gets CGST + SGST. Inter-state gets IGST. Zero-rated exports get their own treatment. No spreadsheets. No rework at month-end.

Place-of-supply aware

Auto-detects intra-state vs inter-state from state codes and applies the correct tax heads without asking.

HSN-keyed rate table

Item-level HSN/SAC with slab mapping. Update a slab once and every future bill uses the new rate.

Filing-ready registers

Sales, purchase, and tax registers export to formats your CA recognises — GSTR-1, GSTR-3B summary, ITC ledger.

Everything in one place

The full ledger of daily operations, quietly running.

Every module talks to every other. A sale reduces stock, updates the customer's ledger, and flags a low-stock alert — all before the invoice PDF is printed.

GST-compliant invoicing

Professional templates matching Rule 46. Serial numbering, PDF export, thermal printing, and duplicate/triplicate copies handled by the format itself.

A4 · Thermal · PDF

Real-time inventory

Stock updates the moment a sale is confirmed. Reorder points trigger low-stock alerts. Multi-unit conversion (piece → dozen → box) is stored on the item, not calculated at bill time.

Barcode · Batch · Expiry

Customers & suppliers

Every party has a GSTIN, a running ledger, and a payment history. Reconciliation happens as you post — not as a month-end scramble.

Ledger · Ageing · Statements

Payments & receipts

Log cash, cheque, UPI, NEFT and card receipts against invoices. Partial payments and advances are tracked cleanly, with outstanding always up to date.

UPI · NEFT · Cheque

Reports & analytics

Sales trends, top items, party ageing, profit-by-item, tax summaries. Filter by date, party, or category — export to Excel or PDF for your CA.

GSTR-1 · P&L · Ageing

Backup, restore, audit

Scheduled backups to local disk or cloud. Full audit trail on who edited what, when. Restore any point-in-time snapshot without losing new entries.

Encrypted · Versioned
The daily view

A dashboard your owner reads, not your accountant.

Sales, receivables, low stock, and profit — one screen, honest numbers, refreshed as you work.

Built for the long run

Security, roles, and reliability — not afterthoughts.

The system your business grows into should protect your data as seriously as you do. Every access is logged. Every backup is verifiable.

Protected Verified Secure

Secure authentication

Password hashing, session expiry, and optional two-factor login. Failed-attempt lockout with admin-visible logs. Data at rest is encrypted.

Role-based permissions

Owner, accountant, cashier, sales staff — each sees only what they need. Grant, revoke, or scope permissions to a branch, module, or single action.

Backup & point-in-time restore

Daily encrypted backups to your local drive, network share, or cloud bucket. Roll back to any snapshot without losing entries made afterwards.

Full audit trail

Every create, edit, delete, and settings change is recorded with user, timestamp, and before/after values. Nothing quietly disappears.

Grows with you

Simple enough for one counter. Serious enough for many branches.

Same product, same interface — the depth is there when you're ready to reach for it.

Small business

Single counter, single owner

Bill, print, track stock, log payments. Everything essential, nothing to configure.

  • One login, one location
  • Cash + UPI receipts
  • Basic reports for the CA
Growing team

Staff, roles, and reconciliation

Add cashiers and accountants with scoped access. Ageing and collections become part of the day.

  • Multi-user with role scoping
  • Party ledgers & statements
  • Purchase order workflow
Enterprise

Multi-branch, multi-GSTIN

Consolidated dashboards across branches, per-GSTIN tax registers, branch-level roles and reporting.

  • Multiple branches & warehouses
  • Multi-GSTIN tax registers
  • API access & custom exports
Straight answers

Questions worth asking before you commit.

Is SmartBill-GST cloud-based or does it run on my own machine?
Both, depending on what suits your business. The default deployment is web-based so you can bill from any counter, phone, or laptop. On-premise installations for shops with intermittent internet are supported — data syncs when connectivity is available.
Does it handle e-invoicing (IRN generation)?
The invoice format is aligned with the government e-invoice JSON schema. IRN generation via the IRP is available for businesses above the applicable turnover threshold, with the QR code and IRN printed back onto the invoice.
Can my accountant work directly in the system?
Yes. Create an accountant role with access to sales, purchases, tax registers, and reports — but not to product master or settings. Exports for GSTR-1 and GSTR-3B summaries are one click away.
What happens to my data if I stop using the product?
Your data is yours. Full exports of invoices, ledgers, and masters are available at any time in standard formats (Excel, CSV, JSON, PDF). No hostage-taking, no format lock-in.
How does support work?
SmartBill-GST is developed and supported by SP System. You get direct email support at spsystem0@gmail.com, onboarding assistance for data migration, and product updates as GST rules evolve.
