Development of a SaaS platform

Budget: 25000 UAH Deadline: 20 days

Mykhailo, I see here not just a SaaS, but a complex cash kiosk system with offline resilience, payment, printing, and AI analytics. I can build this step by step: an admin panel in Next.js, kiosk mode with i18n, translation caching, and secure launch, as well as a Hardware Bridge for the terminal and printer. I have worked with web interfaces and integrations, so I will help design a reliable architecture right away. I am ready to discuss the MVP and implementation risks.

Hello!

I carefully read the technical specifications. Most of it — admin panel, kiosk interface, loyalty, tips, SMS, AI analytics — I will build on your stack (Next.js + Supabase + Electron), there are no questions here. But I will immediately mention two areas where such projects usually get stuck. I checked the Polish specifics before writing to you:

1. Polcard is a brand of Fiserv Polska, and their ECR protocol is closed. Documentation is provided after the acquiring agreement, and the software is certified by Fiserv. If the agreement is already in place — great, we start with that. If not — I will suggest Adyen or myPOS: they have open APIs and ready unattended terminals for kiosks, which will save one or two months.

2. SMS receipts in Poland do not replace fiscal ones. Barber services are fiscalized from the first client through an online cash register with transmission to the CRK — which means a fiscal printer (Posnet/Novitus/Elzab) is needed for the kiosk, and I will incorporate its protocol into the Hardware Bridge from the very beginning. SMS remains as marketing: a link to the receipt and a review on Google Maps.

I work in stages with a demo every 1–2 weeks. The first stage is the admin panel and kiosk on terminal and printer emulators: you will be able to showcase the product to salons even before connecting the hardware.

Two questions that affect the timeline assessment: is there already an agreement with the acquirer, and what hardware will the kiosks use — Windows or Android? Expand

Hello! A large and very well-designed B2B project. The HaaS/RaaS format for the beauty sector is currently at the peak of popularity in Europe, and the stack of Next.js + Supabase + Electron perfectly meets the architectural needs.

I manage the digital agency KenoStudio. We specialize in developing complex interactive web applications, PWAs, and custom management systems (we have extensive experience with Next.js and Supabase). Building a Hardware Bridge through Electron for interaction with peripherals (printers, acquiring) is a classic and reliable solution.

Here’s how we implement this task turnkey:

Backend & Admin CMS: We will deploy a database in Supabase, set up authentication for owners, tabular input for the CMS, and the logic of "hidden loyalty." We will connect the OpenAI API for generating text business insights.

Kiosk Frontend: We will create a responsive vertical interface (9:16) on React/Next.js with i18n localization. We will implement the logic of smart tipping, an upsell module, and log storage in LocalStorage for offline resilience.

Hardware Bridge (Electron.js): We will write a desktop wrapper that will connect the web tab with USB/COM ports for direct control of the receipt printer and payment terminals (Polcard/eService) through Node modules (serialport or native notifications).

Timeline and budget:
A project of this level is divided into clear stages (sprints) due to the volume and work with hardware:

Timeline: 30–40 working days (development, API integration, testing the Hardware Bridge).

Budget: Approximately $1200–$2500 (exact amount after agreeing on the protocols for integrating banking terminals).

I suggest having a short call for 5 minutes on Telegram or Google Meet. We will discuss the documentation of Polish acquiring companies that we plan to work with and finalize the first steps of development. Expand

Hello.

I am a NodeJS developer. I am ready to take it on. Write to me, and we will discuss.

Good evening!

For such a product, it is better to immediately divide the system into three independent circuits: a cloud backend with subscriptions and salon data, a kiosk client in a secure full-screen mode, and a separate Hardware Bridge for working with the terminal and printer. From an architectural point of view, this reduces risks because payments, printing, and the kiosk interface operate under different reliability and update rules.

An important point is not to mix critical business processes with "cosmetic" functions. The visit, payment, status fixation, printing, and synchronization scenarios must first be stable during connection loss, and only then does it make sense to add loyalty, upsell, SMS, and AI summaries. For offline mode, it is reasonable to implement an event queue and status confirmation from the terminal; otherwise, network interruptions will lead to discrepancies between payment, receipt, and records in the admin panel.

A separate risk here is the specific models of Polcard/eService and receipt equipment. Without an SDK, test stand, and real device, the assessment will only be preliminary because such integrations often have limitations on commands, timeouts, and exchange formats. AI analytics and dynamic translations are better built on top of already normalized data with caching to avoid hitting external API limits and increasing operational costs.

If we talk about phased implementation, it is reasonable to assemble the MVP in 8–12 weeks after fixing the equipment, the composition of the first version, and access to the API. For an accurate assessment, we only need three things: which specific models of terminals and printers will be used, whether a multi-tenant SaaS is needed right away or just one salon initially, and which modules are mandatory in the first delivery.

Budget: 27000 UAH Deadline: 30 days

Hello!

I have experience in developing complex web applications using React, Next.js, Node.js, and PostgreSQL, building scalable architecture, implementing personal accounts, CMS, role systems, analytics, and integrating third-party APIs.

For implementation, I propose the following stack:
* Frontend: Next.js (React, TypeScript), Tailwind CSS;
* Backend: Node.js (NestJS), Supabase (PostgreSQL);
* Authorization and subscriptions: JWT + Supabase Auth;
* Hardware Bridge: Electron.js for working with USB/COM devices;
* AI: OpenAI API;
* SMS: Twilio or SMSAPI;
* Local storage and data synchronization for offline mode.

Within the MVP, we can implement:
* multi-tenant SaaS architecture;
* personal account for the owner with CMS and kiosk settings;
* kiosk interface with multi-language support;
* scenarios for new and returning visits;
* loyalty program, upsell, and tipping system;
* analytics and dashboards;
* integration with payment terminals and receipt printers;
* offline mode with subsequent synchronization;
* AI assistant for analyzing metrics and generating recommendations.

The architecture will be designed to connect a large number of independent salons and further expand functionality without the need for serious system overhauls.

For an accurate estimate of costs and timelines, I suggest conducting a technical discussion of the requirements and breaking the project into phases. After analysis, I will prepare a detailed roadmap and implementation plan with the possibility of phased delivery and payment for each completed phase.

I am happy to discuss the project details and offer the optimal technical solution. Expand

Hello!

Our team has carefully reviewed the technical requirements for your SaaS platform for beauty salons. The project looks scalable and technologically interesting. Our team has experience with both complex web interfaces and backend architecture and system integration (Node.js/Electron).

Why we are the best choice for this product:

Full development cycle: We cover the entire architecture: from backend logic on Node.js/Supabase and integration with AI, to developing a hardware bridge on Electron.js, which is critical for stable operation with printers and payment terminals.

Experience with high-load systems: We have experience in developing scalable APIs and working with PostgreSQL/NoSQL, ensuring the stability of your SaaS even when scaling to hundreds of salons.

Frontend expertise: Our experience in React/Next.js and Tailwind will make the kiosk interface not only fast but also intuitive, which is critical for high sales levels (upsell scenarios).

Responsibility: We are used to working in Agile (Jira/Trello), providing regular reports, and ensuring quality code coverage with tests (Jest/Mocha) so that the system is resilient to errors in 24/7 mode.

How we propose to structure the work:

Phase 1: Database design and basic admin panel (Constructor).

Phase 2: Kiosk frontend and hardware bridge (testing connection with printer/terminal).

Phase 3: Integration of payment APIs, AI assistant, and marketing tools.

We have already worked with similar integrations and understand the specifics of working in Kiosk Mode. Do you already have specific models of printers and terminals selected for the first testing phase?

We would be happy to conduct a technical call and discuss the details. Expand

A complete SaaS ecosystem is needed: cloud backend, owner dashboard, and kiosk frontend with a hardware bridge for the terminal and printer.

I would build it like this: backend on Node.js + Supabase (PostgreSQL + Auth + Realtime), dashboard on React with CMS, analytics modules, and an LLM assistant via OpenAI API. Kiosk frontend on React in 9:16, i18n through i18next with hardcoded EN/PL and caching DeepL translations in the database. Hardware Bridge on Electron: it listens to WebSocket from the browser tab and writes to COM/USB printer and terminal.

The key risk that needs to be addressed immediately: offline scenario on the kiosk. If the internet goes down in the middle of a transaction, a local queue with sync after recovery is needed; otherwise, we will lose payments.

What payment terminal is planned (Verifone, Ingenico, PAX, other) and is there already an SDK or protocol for it?

Budget: 22000 UAH Deadline: 22 days

Good day, Mykhailo.

The most complex node of your system is not the kiosk UI, but the Hardware Bridge: the connection between the web tab and the COM/USB ports of the Polish terminals Polcard/eService and the fiscal printer. This is where driver conflicts and delays arise, so the bridge needs a minimalist architecture with a clear message protocol and retry logic — a lightweight local service that holds a queue of commands to the terminal and returns the payment status (success/insufficient funds/timeout/cancellation) without freezing the kiosk interface.

Offline resilience requires not just caching, but a full-fledged conflict resolution strategy: the kiosk locally records visits, tips, and transactions in SQLite/IndexedDB, and when the connection is restored, the server side reconciles loyalty counters without duplicates. Your hidden loyalty ("6th haircut is a gift") depends on the consistency of this counter, so the merging logic needs to be designed from the very start, not added later.

An admin panel on Next.js with Supabase/PostgreSQL will provide salon owners with tabular input without drag-and-drop, while an AI assistant on OpenAPI will generate weekly text summaries with upsell tips — with a cached prompt to keep API costs under control. Dynamic translations via DeepL/Google will be cached in the salon's database, so repeat visits from Spanish-speaking clients will not generate new requests.

Hello! The project is large, and you have chosen the right stack (React/Next + Supabase + Electron), so I will point out where the real engineering lies. The entire web part, admin constructor, kiosk in Kiosk Mode, loyalty, upsells, tips, analytics with AI, is extensive but transparent. However, where the project lives or dies is the Hardware Bridge: the connection between Electron and the physical ports of the payment terminal (Polcard/eService) and the fiscal printer, plus offline resilience (local storage of visits and synchronization when the network returns). This is where I look first: the web can be made beautiful, but if the payment at the terminal fails or the receipt does not print, the kiosk does not work.

Honestly about the hardware: I will integrate with Polish terminals and the fiscal printer using their API, but for this, the devices themselves (or access to a vendor's test terminal) and documentation are needed. Without the physical hardware, the bridge cannot be debugged, so I will move this part to a separate stage when the equipment is in hand. This is more honest than promising blindly.

I propose a phased approach: (1) platform + admin constructor + backend on Supabase, (2) kiosk with all scenarios (visits, hidden loyalty, tips, ratings, SMS receipts), (3) Hardware Bridge and acquiring on real hardware, (4) offline mode and testing. Payment will be phased, with a demo at each stage.

I am ready to discuss the architecture and pitfalls of acquiring for free in private. I look forward to collaborating.

Hello.

I am ready to discuss the development of such a SaaS platform. The project is complex, so I would approach it in stages: first the architecture and MVP, then the admin panel, kiosk frontend, subscriptions, analytics, integrations with payment, printer, and SMS.

The stack is suitable: React / Next.js, Node.js, PostgreSQL/Supabase, TailwindCSS, Electron.js for kiosk mode and working with USB/COM equipment.

It is also important to study the documentation for Polcard/eService terminals and the receipt printer in advance, as hardware integrations can significantly affect timelines.

I can implement:
an admin panel for owners, a kiosk builder, a catalog of services and products, upsell, tips, a loyalty program, multilingual support, analytics, AI reports, SMS receipts, Google Maps review flow, offline data saving, and synchronization.

I suggest starting with a short technical audit of the requirements and breaking the project into phases with a clear assessment of timelines and budget. The MVP can be planned for approximately 6–10 weeks, and the final cost depends on the number of integrations, equipment, and the depth of the admin panel. Expand

Hello! The SaaS platform project for self-service kiosks fully matches our profile. We have extensive experience in developing European B2B SaaS and On-Premise products in the services sector (specifically CortClub for tennis clubs in Europe and wellness platforms in Croatia), where we successfully implemented owner dashboards, revenue dashboards, and multi-tenant architecture.

The specified budget and timelines are very preliminary. We will provide an exact estimate for the sprints after discussing the details of integration with Polish acquirers (Polcard/eService), specifications for receipt printers, and the logic of the AI assistant.

Estimated budget: $14,000 – $18,500
Estimated timeline: 4.5 – 5.5 months.

Work format: Staged payment for sprints (Design and UI/UX ➡️ Development of Cloud Backend & Multi-tenancy ➡️ Web Admin Panel & CMS ➡️ Kiosk Frontend & Localization ➡️ Hardware Bridge, peripherals, and Offline mode ➡️ QA, LLM setup, and Release).

Our relevant experience:
1. CortClub (Europe): Comprehensive SaaS product for tennis clubs. Branded interfaces, revenue dashboards, analytics, currently transitioning the platform to a multi-tenant architecture.
2. Fitness/Wellness SaaS (Croatia): Ecosystem for booking and managing studios, owner dashboards, subscription management, and scheduling.
3. COSINA (Spain): Food delivery platform with online payment integration, catalogs, and real-time order processing.

We know how to implement a stable offline mode (local caching of transactions and synchronization queue during connection loss), as well as integrate DeepL API without exceeding the budget on requests.

I suggest having a short consultation in the chat to discuss the technical nuances of the peripheral equipment and finalize the exact work plan. When would it be convenient for you to chat? Expand

Hello! I have reviewed the technical specifications — the project is monumental, deeply thought out, and architecturally very beautiful. I specialize in backend development, database design, and AI integrations. Your stack (Supabase / PostgreSQL + React / Next.js) is the perfect choice for rapid deployment and high fault tolerance in B2B SaaS.

I will fully handle the development of the backend, database, integration of external APIs, and AI modules.

From an engineering perspective, I see the implementation of key blocks as follows:

Database Architecture (Supabase/PostgreSQL):

I will implement a strict multi-tenant architecture at the security policy level (Row Level Security — RLS). Data from different salons will be hardware-isolated from each other within a single database.

Kiosk Offline Resilience: I will set up state synchronization. In case of a connection drop, the Kiosk Frontend saves transactions in localStorage/IndexedDB, and when the network is restored, the local Hardware Bridge sends batch data to the server via Supabase RPC functions with idempotent keys (protection against duplicate payments).

Localization and Optimization (i18n + Caching):

For dynamic translation (Spanish/French), I will write a trigger at the PostgreSQL level. If a specific UI string for a given salon is not in the translation_cache table, the script makes an asynchronous request to the DeepL/Google API, saves the result, and no longer spends your balance on repeated requests.

AI Analytics and Upsell:

I will write a pipeline for the AI Assistant based on the OpenAI API (GPT-4o-mini). The script will aggregate transactions for the week (revenue, tips, popular masters, hour drops), form a compressed JSON context, and provide the owner with a custom readable summary report with insights on upselling cosmetics.

Hardware Bridge & Fintech (Poland):

I have experience with asynchronous protocols and API integrations. I will implement the processing of end-to-end statuses from terminals (Polcard, eService) on the Hardware Bridge (Node.js/Electron or lightweight Python), ensuring strict error validation (timeouts, cancellations, insufficient funds) before sending the command to print the fiscal receipt.

About myself: I work autonomously, write clean code with strict typing, and always meet deadlines. I am ready to work through Business Safe (all necessary details and status for working with legal entities are available).

I would be happy to discuss detailed database table design and integration with Twilio/SMSAPI in private messages. Let’s create a cool product! Expand

Hello! The project is incredibly interesting, and we are ready to implement it turnkey.
We are a team of two experienced engineers, our synergistic stack and experience perfectly cover the architecture of your project:
1. I am a Full-Stack developer (4+ years of experience): I specialize in the modern stack of Next.js, React, TailwindCSS, TypeScript, Node.js, and Supabase (PostgreSQL). I will develop a flawless, intuitive Web Admin Panel (with a custom CMS/builder) with three design presets, AI analytics on OpenAI, link generation, and integration with DeepL and Twilio. I will also build a sensitive, fast Kiosk Frontend (9:16) with optimized animations (loyalty gifts, "smart tips," feedback system).
2. My colleague is a Senior Python engineer (3+ years of experience with his own ecosystem of libraries): a professional in system programming, hardware integrations, and hardware. He will develop a bulletproof Hardware Bridge (Python / Electron) for reliable synchronous communication between the touch web interface and the physical COM/USB ports of Polish payment terminals (Polcard, eService) and fiscal receipt printers. He will also implement a stable Offline-first architecture (local transaction storage in the kiosk with background synchronization in Supabase when Wi-Fi is restored).
Why our combination is the perfect solution for you:
Fast design using AI: We can develop the visual concept and interface using modern professional AI tools — this will significantly speed up the layout creation process without losing quality and allow us to move much faster to the programming and testing stage.
No blind spots and template solutions: We clearly separate areas of responsibility: I create premium UX/UI and cloud logic, while my colleague ensures that the hardware part works like clockwork. We do not use heavy template builders and know how to write fast custom admin panels from scratch for B2B SaaS projects.
Ready to work with the Polish market: We know the specifics of integrating European payment gateways, SMSAPI, and localization (i18n with hardcoded caching).
🎁 A bonus from us to get started:
We will set up your cloud infrastructure for free, connect the domain, and deploy a test environment (Staging Environment) on reliable free hosting to demonstrate the first prototypes of the control panel.

Hello! I see that you are planning to develop a SaaS platform for barbershops and beauty salons with quite a complex architecture and integrations with equipment. The main tasks ahead of us include implementing a cloud control panel and an interface for kiosks. Given the need to work with payment terminals, cloud databases, and an AI assistant, this requires attention to detail and thorough development of all scenarios. My approach will involve phased development of functionality, with careful testing of all integrations to minimize potential risks when using the system.

Some important points to clarify: 1. What specific functionality are you considering for the AI assistant? 2. Are there already selected APIs for integration with the terminals, or will I need to conduct research? 3. What are the age characteristics of your product's target audience?

The actual timeframe for project completion is estimated at 20 days. This will allow time to work out all the details and integration. On my part, I will ensure a complete development cycle up to deployment on the server and user training.

I am developing on Next.js, Node.js, and Express.js, with experience in creating SaaS platforms, CRMs, personal dashboards, and AI integrations. In your project, it is crucial to lay down the right scalable architecture from the start, so that subscriptions, kiosks, analytics, hardware integrations, and new modules can grow smoothly without rewriting the system. I am ready to propose an optimal stack and implement the project in phases, considering the future growth of the product.

You described a very complex project with a SaaS platform for barbershops. An especially important point is the Kiosk Mode on 24-inch touch screens and offline data processing during Wi-Fi outages - this is a non-trivial task. I have experience with similar things: I recently worked on UI/UX for a SaaS dashboard with integrations and webhooks for leads. Which payment processing platform do you plan to use - Polcard, eService, or another?

Hello. I can help with building a reliable SaaS platform for kiosks, where the primary requirements are a secure kiosk mode, stable payment processing, and correct offline synchronization without transaction duplication. One important nuance that should be discussed in advance is the mechanism for linking the kiosk to the account and secure device authentication to prevent link and configuration tampering. To get started, please clarify if there is already a list of models of payment terminals and receipt printers that need to be integrated. Respond, and I will send a brief set of risks and questions regarding the integration to move forward.
