You need to implement eCommerce for OpenCart Version 3.0.3.6

Development of a SaaS platform and software for self-service kiosks. 1. General project description Development of a B2B SaaS platform based on the HaaS/RaaS model (Hardware/Retail as a Service) for automating sales in barbershops and beauty salons. The product consists of a cloud management panel (Web Admin Panel) and a client web application (Kiosk Frontend) operating on 24-inch vertical touch screens in a secure mode. 2. System architecture Backend (Cloud server): Data storage (PostgreSQL/Supabase), subscription management for owners, processing API requests. Web Admin Panel: Owner's personal account. Kiosk Application: Terminal interface. Hardware Bridge: Local wrapper program (Electron.js or Python) for connecting the web tab of the browser with the physical ports (USB/COM) of the payment terminal and receipt printer. 3. Owner's personal account (Web Admin Panel) Access is provided by subscription. The panel should be as intuitive as possible, without complex drag-and-drop mechanics. Module "Constructor" (CMS) • Uploading the salon logo. • Choosing a visual theme from 3 presets (Light Minimalistic, Dark, Branded). • Tabular input: adding masters (photo + name), service categories, and price list. • "Publish / Launch" button: saves settings and generates a unique secure link. When this link is opened on the kiosk, a ready-to-use interface is launched. Module "Marketing and Upsell" • Adding complementary products (cosmetics) for additional sales. • Setting up automatic discounts ("Happy Hours"). Module "Analytics and AI" • Dashboard: revenue, number of transactions, statistics for each master (including collected tips). • AI Assistant (based on LLM), which summarizes the week's results in text and gives sales advice. 4. Kiosk application (Kiosk Frontend) Vertical interface (aspect ratio 9:16), operating in full-screen Kiosk Mode (strict lockout of access to the operating system). Main navigation and multilingual support • A language selector is located in the corner of the screen. • Localization (i18n): English and Polish languages are hardcoded in the code for instant loading. Other languages (Spanish, French) are translated dynamically via API (DeepL/Google) with mandatory caching of translations in the salon's database to save requests. • Three main buttons on the start screen: "New Visit," "Repeat Visit," "Purchase Products." Scenario "Repeat Visit" and loyalty program • The client enters their phone number for identification. • Hidden loyalty: the system checks the visit counter in the database. If the condition set by the owner is met (for example, "6th haircut"), an animation of a gift is displayed, and a 100% discount is automatically applied. • An offer to repeat the last service with the same master in one click. Scenario "New Visit" and payment • Choosing a master. • Choosing a service. • Upsell screen (offering to add shampoo, paste, or an additional service). • "Smart Tips" screen: a pop-up before the final amount — "Will you leave a tip for the barber [Name]?" Action buttons: "No, thank you," quick denominations (e.g., 5 zł, 10 zł, 20 zł), and "Other Amount" button (calls the numeric keypad). • Payment: transferring the final amount (service + tips + products) through the Hardware Bridge to the bank terminal. Payment waiting animation. Transaction completion and marketing • SMS receipts and Google Maps: an offer to send the receipt via SMS. The SMS integrates a link to the electronic receipt and a request to leave a review on Google Maps (the link to the maps is set in the admin panel). • Quality assessment: the last screen with a photo of the master and 5 stars — "Rate the work." One touch sends the rating to the owner's admin panel and returns the kiosk to the main screen. 5. Hardware and stability requirements Integration with acquiring • Direct API integration with Polish terminals (Polcard, eService). • The system must correctly handle errors: insufficient funds, cancellation by the client, timeout. Integration with printer • Automatic printing of fiscal receipts. Offline resilience • In the event of a short-term Wi-Fi network drop, the kiosk saves visit data locally and synchronizes it with the server when the connection is restored. 6. Recommended technology stack Frontend (Admin Panel + Kiosk) • React • Next.js • TailwindCSS Backend & Database • Supabase (PostgreSQL) • Node.js Hardware Bridge • Electron.js (for packaging the web version into a desktop application with access to USB/COM ports of the hardware) AI & External API • OpenAI API (AI analytics) • Twilio or SMSAPI (sending SMS receipts)

Good day. We are looking for a specialist who understands e-commerce websites for selling products abroad. We need not just a website developer who will "make a beautiful page," but a person who understands: — how websites for custom-sized products should work; — how to properly implement a size chart / price calculator / product parameter selection; — how to design a product card so that the client understands how to order; — how to make the website convenient for advertising, SEO, and further promotion; — how to launch such websites in foreign markets. We have made-to-order products where the client must choose parameters: size, color, type of fabric, installation option, etc. Therefore, it is important that the specialist has practical experience with similar projects. These do not necessarily have to be curtains. Experience with any custom-made products will be suitable, for example: — custom-sized furniture; — blinds / shades / pleated shades; — windows / doors; — clothing with a size chart; — mattresses; — products with a price calculator; — any product where the price depends on the client's parameters. At the first stage, we need to get a consultation / audit and understand: What type of website is best to create for our product. Which platform is better to launch on: Shopify, WordPress/WooCommerce, PrestaShop, OpenCart, or others. How to properly implement the selection of size and product parameters. How the product card should look so that the client does not get confused. How to best create a price calculator or order form. What must be on the website to build client trust. How to prepare the website for Google / Meta advertising. How to prepare the website for the foreign market. What mistakes should not be made at the start. What is the minimum version of the website that can be created for demand testing. It is important for us not just to "make a website," but to understand the correct launch strategy: structure, logic, functionality, technical base, promotion, and further scaling. We expect from the specialist: — practical cases of similar websites; — understanding of e-commerce abroad; — experience with custom-made products or products with a size chart; — the ability to explain in simple terms what is best to do at the start; — preferably experience with websites that were launched for advertising or SEO. At the first stage, we want to conduct a consultation of 60–90 minutes or receive a brief audit/launch plan. In your response, please write: Do you have experience with websites for custom-sized products? What specific projects can you show? What platforms have you worked on? What would you recommend for the start: a full-fledged website or a test version? What is the cost of the consultation or initial audit? When can you have a short call?
