The situation

Billing and stock are tracked separately, so the figure on screen and the goods on the shelf disagree. Invoices are slow to produce at the counter, outstanding payments are known approximately, and the monthly reconciliation exercise exists purely because the two systems were never connected.

What this solution does

This solution joins billing and inventory into one record. Every invoice reduces stock, every purchase increases it, reorder alerts come from real consumption, and outstanding payments are visible by customer and age — with reminders that go out without anyone remembering to send them.

How it works

  1. Masters set up

    Items with units, HSN codes, barcodes and rates; customers with GSTIN, price category and credit terms; suppliers and tax configuration.

  2. Purchases recorded

    Goods inward against purchase orders updates stock, costing and supplier payables in one entry.

  3. Billing at the counter

    Barcode scanning or quick item search produces a GST-compliant invoice in seconds, with stock reduced automatically.

  4. Payments tracked

    Receipts recorded against invoices, including part payments and advances, with live ageing by customer.

  5. Review and act

    Reorder suggestions from actual consumption, non-moving stock reports, and automated payment reminders to overdue accounts.

The difference it makes

What changes once this is in place

Stock and books agree

One record for both means the monthly reconciliation exercise largely disappears.

Faster counter, shorter queues

Barcode billing with saved rates means seconds per invoice at the busiest hour.

Money collected sooner

Live ageing plus automatic reminders measurably shortens how long payments stay outstanding.

Working capital freed

Reorder suggestions and non-moving reports stop you funding stock that will not sell.

What's included

  • Item, customer and supplier masters with multiple price lists
  • GST-compliant invoicing with e-invoicing support where applicable
  • Barcode-based billing and stock entry
  • Multi-location stock with transfers and in-transit visibility
  • Batch, serial and expiry tracking where relevant
  • Purchase orders, goods receipt and supplier payables
  • Payment recording, ageing analysis and automated reminders
  • Reorder level alerts and purchase suggestions from consumption data
  • Reports: daily sales, item movement, stock valuation, ageing, GST summary
  • Tally integration and Excel export

This is a good fit if

  • You maintain stock and issue invoices, currently in separate places
  • Physical stock and recorded stock routinely disagree
  • Outstanding payments are tracked informally
  • Billing is slow at peak hours

Limitations you should know about

Every solution has constraints. We would rather you read them here than discover them after signing.

  • The system cannot correct movements that happen without an entry; gate and counter discipline is a prerequisite
  • Statutory accounting, audit and return filing are better left to accounting software; we integrate rather than replace
  • Browser-based operation needs connectivity, so sites with unreliable internet should consider local deployment or an offline queue
  • Tax rules change, and your CA should review the tax configuration before go-live

Technology we typically use

  • Next.js
  • PostgreSQL
  • FastAPI
  • Barcode scanning
  • GSP e-invoicing APIs
  • Thermal printing

Questions

Inventory & Billing System — common questions

Will this replace Tally?
For billing, stock and receivables, yes. For statutory accounting, audit and GST filing, we recommend keeping Tally and syncing to it, because your accountant and auditor already work there and replacing that creates risk without benefit.
Can it handle our unit conversions?
Yes — purchase in bags and sell in kilograms, buy in cartons and issue in pieces. Conversion factors are set per item and the audit trail is kept in both units.
Do we need new hardware?
Usually not. It runs in a browser on your existing computer and works with common barcode scanners and thermal printers. A tablet suffices for a secondary counter.
What happens if the internet goes down?
If billing cannot stop, we deploy locally with cloud sync or add an offline queue that holds invoices and submits them on reconnection. We size the approach to how much downtime risk you actually carry.
