Hello, I will deliver your pilot-ready POS platform in Flutter — Android smart terminal build, local-first SQLite/Hive data layer with cloud sync, and the payment abstraction layer for semi-integrated EMV integration. For offline-first conflict resolution, I will implement a CRDT-based merge strategy with vector clocks on each transaction record. This ensures that when two terminals process sales during an outage, the sync engine resolves conflicts deterministically without data loss — critical for multi-tender tabs that may be open across shifts. Questions: 1) Which semi-integrated EMV terminal or processor are you targeting first — PAX, Ingenico, or another? 2) For multi-tenant isolation, do you prefer schema-per-tenant or row-level security at the database layer? Send me a message and we can go over the details. Best regards, Kamran

Hi, Your POS platform is exactly the kind of complex, long-term product I enjoy building. I have experience delivering production-grade Flutter applications with offline capabilities, payment integrations, multi-tenant architectures, and scalable backend systems. For this engagement, my team can provide a detailed module-level breakdown covering POS workflows, offline-first synchronization, EMV abstraction, inventory, tab management, employee controls, customer displays, and pilot deployment readiness. We understand that reliability is critical in hospitality environments where operations must continue even without internet connectivity. Our approach would include: • Flutter architecture optimized for Android smart terminals and future Windows support. • Local database with conflict-aware cloud synchronization. • Processor-agnostic payment abstraction to support semi-integrated EMV terminals. • Secure multi-tenant design with tenant isolation and branding capabilities. • Comprehensive testing, documentation, and deployment preparation. We can provide both fixed-price and time-and-material proposals with assumptions, contingencies, team composition, and a realistic pilot timeline after reviewing the detailed specification under NDA. I would welcome a brief call to discuss the specification and share relevant experience involving offline applications, SaaS platforms, and payment integrations to establish an accurate scope and quote. Best Regards, Jemin Sagar

Hi there, I understand you are seeking an experienced team to deliver the first pilot-ready phase of a Flutter-based POS platform for bars and lounges, including offline-first operation, multi-tenant architecture, semi-integrated EMV payments, pricing rules, dual pricing, multi-tender settlement, tab management, inventory, kitchen routing, customer display, and Windows extensibility from the same codebase. I have experience delivering complex Flutter applications, payment-integrated systems, offline synchronization architectures, role-based security, multi-tenant SaaS platforms, inventory workflows, and production-grade transaction systems where reliability, auditability, and operational continuity are critical. I would begin with a detailed review of the specification under NDA, break the pilot scope into modules with effort estimates, define the local-first sync architecture and payment abstraction layer, identify certification dependencies early, and provide both fixed-price and time-and-materials options with assumptions, risks, and a phased roadmap toward production deployment. Q1: Which semi-integrated payment processor and terminal hardware are currently preferred for the pilot phase? Q2: Is the cloud backend already selected (AWS, Azure, GCP, Supabase, custom), or should architecture recommendations be included in the proposal? Q3: For the pilot deployment, how many locations, terminals, and concurrent users should the system be sized for? Best regards, Stratos

@CANWS

Hi, Your focus on offline-first operation, EMV payment abstraction, and multi-tenant architecture is exactly what makes this project interesting. Building a POS for live bar environments requires reliable transaction handling, sync resilience, and payment workflows that continue working when connectivity doesn’t. I’ve worked on Flutter-based business applications involving payment integrations, role-based access, inventory workflows, and cloud synchronization. After reviewing the specification under NDA, I can provide a detailed phase-one proposal with module-level estimates, timeline, fixed-bid and T&M options, EMV certification considerations, assumptions, and risk assessment. A quick question: which semi-integrated payment processor are you targeting for the first release? I’d be happy to review the specification and discuss the pilot rollout requirements. Thanks

@aadips

Bar and lounge POS has specific demands that generic restaurant POS systems usually fail. Open tabs that move with the customer from the bar to a table, split-by-item billing, fast bottle service drops, and reliable offline mode when the venue WiFi inevitably drops on a Friday night. My approach: Flutter for both mobile (server pads, manager dashboard) and desktop (countertop POS) with a shared business logic layer. Backend in Node.js with Postgres for transactional integrity, Redis for live tab state, and a sync engine that resolves conflicts cleanly when devices reconnect. Stripe and Razorpay for payments, integrated cash drawer and thermal printer support. Inventory management with stock alerts, recipe-based pour costing, and bottle-deposit tracking. Live dashboard for the owner showing covers, average spend, and stock movement. Webneco has shipped 6+ Flutter POS systems including cafe and quick-service builds. 4.9 stars across 118 reviews, 97 percent on-budget, 15 member team. How many venues launch initially, and is hardware (printers, cash drawers, barcode scanners) already chosen or part of this scope?

Open tabs spanning hours, drinks from multiple staff on shift, and unreliable venue WiFi on a packed Saturday. A bar POS has to be built around those constraints from day one, not patched in later. The architecture I'd use: offline-first Flutter client with a local SQLite queue, idempotent order and payment writes keyed on client-generated UUIDs, and a SaaS backend that reconciles on reconnect. A waiter can take six drink orders during a network drop and they all land correctly when the signal comes back, no duplicates, no lost tabs. Inventory I'd model at the ingredient level with a recipe layer. A cocktail depletes from multiple ingredients per pour, and that detail matters for waste tracking and cost analysis. Bottle-level tracking is quick to build but gives you coarse numbers. M1: Auth, tenant setup, Flutter shell, offline sync core. 144,400 INR, 8 days. M2: Order management, open tab model, multi-staff table assignments. 144,400 INR, 10 days. M3: Inventory and recipe engine, per-pour depletion, low-stock alerts. 144,400 INR, 9 days. M4: Payment processing, split bills, offline payment queue, end-of-night reconciliation. 144,400 INR, 10 days. M5: Reporting dashboard, shift summaries, SaaS billing and subscription management. 144,400 INR, 8 days. Total: 722,000 INR, 45 days. Before I lock in the data model: are you building this for a single venue or as a multi-tenant SaaS from the start? That shapes the backend meaningfully and I want to get it right before M1.
