We build custom POS systems for retail chains, restaurants, clinics, and service businesses in Noida and Delhi NCR — fast billing, inventory sync, multi-location reporting, loyalty programmes, and integrations with your payment gateway, accounting, and delivery platforms.
Web Development Service #22 / 58
Generic POS software handles average retail. Your business has specific product configurations, pricing rules, staff permissions, discount structures, and reporting requirements that generic software forces you to work around. We build POS systems that work exactly the way your counter works — fast, reliable, and integrated with the rest of your business.
Marketing Wise has delivered 20+ custom POS systems for retail chains, QSR and restaurant groups, diagnostic labs, salons, and service centres across Noida, Delhi, and Gurugram. Our builds range from single-outlet tablet POS for boutique retailers to multi-location cloud POS networks with centralised reporting, kitchen order ticketing, and loyalty programme management across hundreds of outlets.
We build POS systems that are fast above all else — a billing transaction that takes more than 10 seconds is a problem at a busy counter. We also build for reliability: offline mode that keeps billing running when the internet goes down, and sync that reconciles all transactions when connectivity restores. A POS that fails at peak hour is not a software problem; it is a revenue problem.

No mystery phases. Four gates every POS engagement crosses — from counter workflow mapping to live billing.
We map every billing scenario at your counter — product types, pricing rules, discount structures, payment modes, and edge cases (void, refund, exchange, split bill). Hardware requirements are assessed — printer model, scanner type, payment terminal, and whether offline mode is required.
Product catalogue, billing flow, GST invoicing, payment gateway integration, and real-time inventory deduction are built and tested. A test counter setup with your actual hardware is done mid-build to catch printer and scanner compatibility issues before UAT.
Multi-outlet support, centralised reporting, promotion engine, loyalty programme, and third-party integrations (Tally, delivery platforms, kitchen display) are built. A full end-of-day reconciliation test is run across all outlets to verify settlement accuracy before go-live clearance.
One pilot outlet goes live first — staff are trained, the first week's transactions are reviewed daily, and issues are fixed rapidly. Once the pilot outlet is stable, remaining outlets roll out on a weekly schedule. Each outlet goes live with a half-day training session and a quick-reference card for staff.
Billing time per transaction reduced from 3.5 minutes to 48 seconds. Stock discrepancy across outlets reduced to near-zero. Central management visibility into real-time sales by outlet improved decision-making speed significantly.
The chain was running 3 different POS systems across 18 outlets — some on Tally, some on a legacy system, one on paper. Stock data was unavailable centrally. Management got a consolidated sales figure only once a week. Promotions were communicated by WhatsApp and applied inconsistently.
We built a unified cloud POS with barcode billing, GST invoicing, outlet-level and SKU-level real-time stock, a centralised promotion engine, a loyalty programme across all 18 outlets, and a management dashboard with live sales, stock, and conversion data per outlet.

Kitchen order error rate reduced from 8.3% to 0.4%. Average table turnaround time improved by 22%. Zomato and Swiggy order management consolidated into the same POS, eliminating the separate tablet per platform.
The QSR chain was using separate systems for dine-in (manual KOT on paper), takeaway (manual billing), and delivery (Zomato and Swiggy tablets). Kitchen staff received inconsistent order tickets, errors were frequent, and management had no consolidated view of covers, revenue, or item popularity across channels.
We built a restaurant POS with digital KOT routed to kitchen display screens, table management with cover count and order merging, integration with Zomato and Swiggy order APIs so delivery orders appear in the same POS queue as dine-in, and a centralised analytics dashboard showing channel-wise revenue and item velocity.
React (POS + KDS), Node.js, PostgreSQL, Zomato/Swiggy API, Razorpay, Redis, WebSocket (real-time KOT)
Patient wait time at billing counter reduced from 12 minutes to 3 minutes. Test result delivery time improved by 34%. TPA claim submission errors eliminated.
Each collection centre billed patients using Tally with manual test entry. TPA patients required looking up empanelment and co-pay amounts from a printed rate card. Sample tracking between collection centre and lab was done by phone. Results were emailed manually.
We built a lab POS with patient record management, test catalogue with doctor-wise ordering and package bundling, automatic TPA co-pay calculation for empanelled insurers, sample barcode printing at collection with tracking through lab processing stages, and automated WhatsApp result delivery when the report is approved.

"They delivered our platform in 12 weeks, on budget and exactly to spec. Weekly demos kept us informed at every stage and the final product matched the requirements document line by line."
"The API architecture they designed handles our peak load without breaking a sweat. We have had zero downtime in eight months of production. The codebase is clean, documented, and our internal team can extend it independently."
"We evaluated three development agencies before choosing Marketing Wise. Their scoping process was the most rigorous — they produced a requirements document that found two gaps we had not identified ourselves."
"The backend they built scaled from 500 to 15,000 daily active users in six months without a single architecture change. That kind of headroom built into the design is rare from an agency engagement."
"Post-launch support was exceptional. They flagged and fixed two edge cases we had not anticipated within 24 hours. The handover package — source code, infra docs, runbook — meant our team could take ownership immediately."

"Custom software built around your exact workflow — not a template, not a shortcut. Engineered to scale, secured from the ground up, and yours outright."
Marketing Wise builds custom point of sale systems for businesses in Noida and Delhi NCR — fast billing, GST-compliant invoicing, real-time inventory sync, multi-location reporting, loyalty programmes, offline mode, and integration with payment gateways, Tally, and delivery platforms.

A focused single-outlet POS with billing, inventory sync, GST invoicing, and basic reporting starts at ₹7 lakhs. Multi-location cloud POS with loyalty, promotion management, kitchen display, and delivery integration typically ranges from ₹12–25 lakhs depending on outlet count and feature scope.
A focused single-location POS takes 10–12 weeks. Multi-location systems with loyalty, promotion engine, and third-party delivery integration take 14–18 weeks. Hardware procurement and testing (thermal printers, scanners, payment terminals) adds 2–3 weeks to deployment timelines.
Yes. Our POS runs as a web application in any modern browser — it works on Windows tablets, iPads, and Android tablets without a separate app installation. Thermal printer pairing, barcode scanner input, and Razorpay terminal integration all work from the browser via standard USB/Bluetooth HID protocols.
Yes. We integrate the NIC e-invoice API (IRP) so B2B invoices above the applicable turnover threshold automatically generate an IRN and QR code. The e-invoice details are printed on the customer copy and stored against the transaction record for GST return preparation.
Yes. Our POS systems are designed for outlet addition as a configuration operation — new outlet name, stock location, staff accounts, and tax registration details are added from the admin panel. No development work is required to onboard a new outlet once the core system is live.
