Deployable EPOS with Mobile App

@softsolution2000

I understand you need a fully-functioning EPOS system with a Windows installer, web back-office, card payment integration, mobile app, and database sync. I will ensure all essential features are met, including real-time transactions, multi-gateway support, and deployment notes. I will deliver a functional software, admin side, and ensure Stripe payment test and product sync work flawlessly. My expertise in PHP, C#, and web development ensures a seamless delivery. Let's discuss further to align on the project scope and budget.

I can help with this, I will deliver a production-ready Windows EPOS package with touchscreen till interface, receipt printing, and a web back-office for product management, stock control, reports, and staff roles. Payment processing will cover Stripe, PayPal, and Square through a unified API layer with real-time settlement. The companion app will be built in Flutter for iOS and Android, covering live sales, stock views, and price updates. For offline resilience, I will set up a local SQLite database with a background sync service that queues transactions and resolves conflicts automatically once connectivity returns. Questions: 1) Which receipt printer hardware are you using — thermal ESC/POS, or another protocol? 2) Do you need multi-location support in the back-office, or is this a single-store setup? 3) For card payments, will you provide your own Stripe/Square merchant accounts, or do you need help setting those up? Looking forward to talking through the details. Kamran

Hi there, I’ve read your EPOS brief and I’m confident I can package and hand you a production-ready Windows-based EPOS with a robust web admin and cross-platform mobile companion. I’ll start from your solid core and deliver a drop‑in installer or portable EXE, touchscreen-optimized till UI, and reliable offline mode with nightly cloud sync. I’ll build a web back-office for bulk image uploads, stock edits, reports, and staff management, plus Stripe, PayPal, and Square as core gateways integrated in a single payment layer with real-time settlements and clear on-screen confirmations. For the mobile app, I’ll provide a shared codebase (Flutter or React Native) with iOS/Android builds and a future parity plan for quick store submissions. A local database with resilient sync ensures the till stays operational during outages, and I’ll include thorough deployment notes and a concise hand‑over session for your onsite tech. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. The plan emphasizes clear collaboration and a pragmatic, solution-focused approach rather than hype. What are your preferred deployment targets and versioning strategy for the Windows installer, and do you want automated tests for the core POS flows (sell, refund, stock adjust) in the admin panel? Also, should I prepare a pilot with a single store to validate the end-to-end flow before wider roll

Hi, I can build and deliver a ready to use EPOS system for Windows with a smooth touchscreen till interface, receipt printing, web admin panel for products stock reports and staff, real time card payments with Stripe PayPal and Square, mobile app support for iOS and Android, offline ready local database with cloud sync, and full installer setup with deployment guide so your team can run it without issues from day one. I have strong experience working with POS and retail systems where reliability and speed are critical. I have handled payment integrations, offline sync systems, and admin dashboards that control daily operations like stock, users, and reporting. I understand how important it is that the system works even without internet and syncs data properly when back online. I focus on delivering stable builds quickly, especially when a near ready solution is needed with minor adjustments instead of starting from zero. I can provide a working demo where you can test a full sale flow with live payment and instant dashboard update and I am ready to start fast and deliver a production ready package with full setup support and handover. Ping me on chat to discuss all the things in detail and move forward. I'm waiting for your response. Thanks.

Hello, I understand you need a ready-to-use EPOS system for a Windows POS terminal with core features stable and some minor tweaks allowed. I will provide a Windows installer or portable executable that runs a touchscreen-friendly till interface, supports printing receipts, and works smoothly. The web back-office will let you manage stock, upload product images, handle staff, and generate reports easily. Payment integration with Stripe, PayPal, and Square will allow real-time transactions with instant confirmation. The companion mobile app supporting both iOS and Android will show live sales, stock, and enable price updates, built with a single codebase like Flutter. The system will use a local database syncing automatically with the cloud, ensuring offline operation if the connection drops. I will supply clear deployment notes and run a hand-over session for your onsite tech. To deliver the right solution, I need to clarify a few points: What versions of Windows will the POS terminals run on? Do you have existing white-label EPOS software or parts ready, or should I set up everything from packaging the stable core? Which payment gateways should have top priority for integration beyond Stripe, PayPal, and Square? What reporting features do you need from the web back-office? Do you need ongoing support after deployment or just the hand-over session? What Windows versions do your POS terminals use and do you already have any parts of the EPOS system ready for packaging?

Hi! I can help you with this EPOS project. I've built similar POS systems with offline-first local databases that sync nightly to the cloud, and the payment integration side with Stripe and Square is something I've done before. For the companion mobile app, Flutter is my main stack so a single codebase for both iOS and Android works perfectly. The front office till interface, web back-office with bulk uploads and reporting, and the real-time payment confirmations are all things I've handled in past projects. I'm Edward, 10+ years of experience across Flutter and PHP. If you've got a white-label base that covers most of this, even better since I can adapt fast. Let me know if you want to chat through the details.

@Herculesz

Hi The main challenge here is not building POS screens alone, but delivering a production-ready EPOS that works reliably on a Windows terminal, stays operational offline, syncs cleanly to the cloud, and keeps payments, stock, and reporting consistent across till, web admin, and mobile. I have experience with full-stack POS and commerce systems involving desktop deployment, local database sync, web back-office tools, payment gateway integrations, and cross-platform mobile apps. I can help either adapt a strong existing EPOS base or finalize a near-ready solution with the right packaging, configuration, and targeted adjustments for your workflow. I would structure this with a stable front-office app for touchscreen use, receipt printing, and offline sales, plus an admin panel for products, images, stock, staff, and reporting, all connected through a clean sync and payment integration layer. Stripe, PayPal, and Square can be handled through a unified transaction architecture so confirmations, settlement status, and dashboard visibility remain consistent in real time. My focus is a dependable handover-ready system with clear install notes, organized codebase, and a practical deployment path for your onsite tech. Thanks, Hercules

@zainalitariq245

Hi I have carefully reviewed your project details and understand that you’re not looking to build a POS system from scratch but need a fully working EPOS solution that is already stable and can be packaged configured and deployed directly on a Windows based terminal with minimal adjustments. The system will include a touchscreen friendly front office interface for handling sales receipts and daily operations along with a web based admin panel where you can manage products stock staff and reports easily. I will ensure seamless payment integration with Stripe PayPal and Square with real time transaction confirmation while also setting up a local database that keeps the POS running offline and syncs automatically with the cloud.

Your offline-first requirement is the critical piece here. Most off-the-shelf EPOS solutions fail catastrophically when the network drops because they rely on constant cloud connectivity. If your POS terminal loses connection during a Saturday rush, you're losing revenue every minute the system is down. Before I recommend an integration strategy, I need clarity on two things: What's your expected transaction volume per terminal during peak hours - are we talking 50 sales or 500? And does your current infrastructure support local SQL Server or PostgreSQL, or are you running lightweight SQLite that might bottleneck under concurrent writes? Here's the architectural approach: - WINDOWS DEPLOYMENT: Package the POS as a ClickOnce installer with embedded Chromium for the UI layer, ensuring touchscreen drivers work across HP, Toshiba and Epson hardware without manual calibration. - PAYMENT GATEWAY INTEGRATION: Build a unified payment abstraction layer that routes Stripe, PayPal and Square through a single interface with automatic fallback - if Stripe times out, the system tries PayPal within 2 seconds to prevent abandoned transactions. - OFFLINE SYNC ARCHITECTURE: Implement a conflict-resolution queue using SQLite for local transactions with timestamp-based merging - when connectivity returns, the system reconciles cloud data without overwriting legitimate sales records. - FLUTTER MOBILE APP: Deploy a single codebase targeting iOS 13+ and Android 8+ with real-time WebSocket updates, so price changes pushed from the back-office appear on manager devices within 5 seconds without requiring app restarts. - DATABASE SCHEMA: Design normalized tables with proper indexing on product SKUs and transaction timestamps to handle 10K products and 100K historical sales without query degradation. I've deployed similar hybrid POS systems for 3 retail chains that needed offline resilience during internet outages. The last one processed £2.4M in its first year without a single payment failure. Let's schedule a 20-minute technical call to walk through your existing infrastructure and confirm the deployment timeline - I don't start builds until edge cases like receipt printer compatibility and VAT calculation rules are documented.

@Feriver

Hello, I can deliver a fully deployable Windows EPOS system with a stable till interface, touchscreen support, receipt printing, and real-time payment integration via Stripe, PayPal, and Square. The platform will include a web-based back-office for product management, stock control, staff administration, and basic reporting. Local databases will sync nightly with the cloud, ensuring offline functionality and seamless updates. A companion mobile app (iOS/Android) can be provided later, built from a single codebase for live sales monitoring, stock checks, and price adjustments. The system will include full deployment notes, hand-over instructions, and optional demo to verify front-office and admin functions. All source code, DB schema, and config files will be delivered in a single package, ready for replication and future extensions. I can also adapt an existing white-label EPOS to meet your acceptance criteria, ensuring rapid deployment while maintaining stability, realism, and store-ready performance. Questions: 1. Do you prefer the initial Windows EPOS to include any sample products or start with an empty catalog? 2. Should card payments settle directly into live accounts during demo, or can test/sandbox mode be used initially? Thanks, Asif

@kareemmaize

Hi there To get this EPOS live quickly, the most critical part is turning the current system into a dependable production package with stable payments, offline-safe sync, and a back office that works cleanly in daily use. I’ll approach this by auditing the existing EPOS foundation first, then tightening the Windows deployment flow, payment layer, and sync cycle so the till, admin panel, and future mobile app stay in sync without fragile workarounds. This ensures you get a system that is ready to install and operate, not just a demo. This means I understand how to handle “package, configure and hand over a production-ready build” while keeping card payments, receipt printing, and touchscreen usability dependable. I’ve worked on operational systems where deployment reliability, payment flow correctness, and cross-platform coordination mattered more than starting from scratch. My process is simple: review the current build and gaps → stabilize POS, admin, payments, and sync → validate test sale, stock/image sync, and deployment flow → deliver handoff package and documentation. I’m ready to begin with a technical audit of the current EPOS and define the fastest path to a production-ready release..

Hi there, I have read your project requirement. You need a native Android application (Kotlin) that runs as a persistent background service to perform scheduled screen recording using MediaProjection, with configurable schedules, overlay indicator, local storage management, and full compliance with Android 10+ restrictions. We have strong experience building Android background services and system-level features using Kotlin. We can develop a stable solution using foreground services, proper permission handling, and a clean MVVM architecture to ensure maintainability and scalability. Our approach: ============ Implement MediaProjection-based screen recording with scheduled triggers Build a persistent foreground service with notification channel (Android compliance) Create scheduling system (time ranges, dates, custom rules) Develop a simple UI for managing recording plans Add a non-intrusive overlay indicator during recording Implement local storage management (rotation, auto-delete by size/age) Ensure compatibility across Android 10+ with proper lifecycle handling A few quick questions: =================== Do you need audio recording (internal/mic) along with screen capture? Should recordings be encrypted or is plain local storage fine? Do you want export/share options for recorded files? Any future requirement for cloud sync or remote control? Best Regards, Srashtasoft Team

@royalwebraisers
