POS Software Development & uniCenta POS Customisation Services

Why we build POS on uniCenta

uniCenta oPOS is a mature open-source point of sale with a Java codebase, a real database behind it and support for the peripherals a counter actually uses. It is the same commercial argument as the rest of our open-source practice: there is no per-till licence fee, so a chain that opens its fourth outlet pays for hardware and configuration rather than for permission to bill.

What uniCenta does not ship is your business. Tender types, receipt layout, discount authority, batch handling, tax treatment and the link to your accounts all have to be built. That customisation is the engagement — the platform is just where it starts.

The till has to work when the line goes down

Retail connectivity in India is not dependable, and a counter that stops billing because a link dropped loses the sale, not just the transaction. Tills hold a local database and continue billing, printing and taking payment offline. Queued sales post to the central ledger when the connection returns, and the sync is reconciled rather than assumed — a till that has not checked in is visible from the back office.

Hardware at the counter

Barcode scanners, thermal receipt printers, cash drawers, customer displays and card terminals are handled through standard interfaces, so you are not tied to one supplier's kit. Weighing scales integrate for loose goods, which matters in grocery, provisions and produce where the item is priced by weight at the counter. Batch and expiry data is captured at the till, so expired stock cannot be billed and near-expiry stock is reported while it can still be moved.

We supply and set up the hardware where you want that handled, and train staff at the counter rather than in a classroom.

One ledger, not two

The point of integrating POS with ERP is that nobody types the day's takings anywhere. Sales, tenders, discounts and returns post into the accounting ledger from the transaction itself. Stock moves out of the outlet in the same operation. Shift and cashier reconciliation, cash declaration and Z-reports come from the same data, so a short till is identified at closing rather than at month-end.

For multi-store operators, prices and promotions are set centrally and pushed to every counter, and each outlet reports on the same basis without a store-level spreadsheet in between.

GST billing and e-invoicing

Counter bills are GST-compliant with correct HSN, rate and tax split. B2B invoices raise an IRN against the e-invoice portal directly from the sale, and the QR code prints on the invoice. Thresholds and rules change, so the configuration is set against what is in force at go-live and revisited as part of support.

From one counter to a chain

A single shop moving off a standalone billing package and a twenty-outlet chain are the same platform with different amounts of work between them. We scope both the same way: study the counter first, then decide what standard uniCenta covers and what has to be built.
