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.
