POS Software
A point-of-sale system processes transactions at checkout, manages inventory in real time, and reconciles sales against stock. Beacon Coders builds these starting from a proven module set for transaction processing and inventory sync, with a specific design constraint most generic POS products handle poorly: the system needs to keep taking payments during an internet outage and reconcile cleanly the moment connectivity returns, since retail checkout cannot simply stop because a connection dropped. Projects start at ₹3,50,000 / $4,200 and typically run 10 to 18 weeks.
The standard module set
Every POS build includes transaction processing with support for cash, card and UPI payments, real-time inventory deduction on sale, a returns and exchange workflow, and daily sales reporting and reconciliation. Multi-terminal support for stores with more than one checkout point is standard, with all terminals syncing to a central inventory record.
Offline-first design, and why it matters
Retail environments — particularly in India, where connectivity can be inconsistent even in urban areas — cannot afford a POS that stops working the moment the internet drops. We build offline-first architecture as standard: the terminal continues processing transactions locally during an outage, queuing them for sync, and reconciles automatically against the central system once connectivity returns, including resolving conflicts if the same inventory item was sold from two disconnected terminals during the outage window. This reconciliation logic is often the single most technically demanding part of a POS build and the part most likely to be under-built in a cheaper generic product.
GST and Indian retail compliance
GST-compliant billing is built into the transaction module as standard for Indian retailers, including correct tax calculation by product category, HSN code assignment, and GST-compliant invoice formatting. For retailers above the e-invoicing threshold, IRN generation against the government portal is built into the billing flow rather than left as a manual export step.
What typically needs customising
Loyalty and discount program logic varies significantly between retailers — tiered membership discounts, point accumulation, and promotional pricing rules are common customisations beyond the standard transaction flow. Integration with a specific weighing scale or barcode printer already in use, and multi-location inventory transfer logic for retailers with several stores, are also frequent requirements.
Integration points
POS systems typically integrate with payment gateways for card and UPI processing, accounting software for sales reconciliation, barcode scanning and label printing hardware, and in some cases an ecommerce platform for retailers running both physical and online stores that need a single inventory record across both.
When to buy off-the-shelf POS software instead
If you run a single store with straightforward inventory and no unusual offline reliability requirements, an established product like Vyapar, Petpooja, or similar will likely serve you at lower cost. Custom POS development earns its cost once your offline reliability requirements, multi-location inventory complexity, or integration needs with existing systems genuinely exceed what an off-the-shelf product handles well.
Frequently asked questions
The terminal continues processing transactions locally, storing them in a local queue rather than blocking checkout. Once connectivity returns, queued transactions sync to the central system automatically, with conflict resolution logic handling the rare case where the same inventory item was sold from two disconnected terminals during the outage.
Yes, GST calculation by product category and HSN code assignment are built into the transaction module as standard, along with GST-compliant invoice formatting and IRN generation for retailers above the e-invoicing threshold.
Yes, this is a common requirement we scope explicitly during discovery — whether you need a single consolidated inventory view across locations, per-location stock with transfer capability between stores, or both, depending on how your retail operation actually runs.
Yes, where retailers run both physical and online channels, we integrate inventory so a sale on either channel updates the same stock record, preventing the common problem of overselling an item that shows available online but was already sold in-store.
We integrate with standard barcode scanners, receipt printers, cash drawers, and card payment terminals, and can work with weighing scales for retailers like grocery stores that need weight-based pricing. Specific hardware compatibility is confirmed during discovery against what you already own or plan to purchase.
Yes, every POS project includes a support agreement with named response times, treated with particular urgency given that POS downtime directly stops a retailer from taking payments — this is one of the few solution categories where we recommend a same-day response tier as standard rather than optional.
Yes, this is a common customisation — point accumulation, tiered membership discounts, and targeted promotional pricing are built against your actual loyalty program rules during discovery, linked to a customer record so repeat customers are recognised automatically at checkout rather than requiring manual discount entry.
End-of-day reconciliation consolidates transactions from every terminal and payment method into a single report, flagging discrepancies between expected and actual cash drawer totals automatically. For multi-location retailers, this rolls up into a consolidated daily report across all stores, so a manager does not need to review each location's numbers separately.
