Hello Gordon, I hope this proposal finds you well and excited about the Square POS System Setup project brief you've shared. I've carefully reviewed the objectives and scope of the project, and I'm confident in my ability to deliver the required functionalities. I propose to develop a comprehensive system that auto-applies member discounts via payment cards on Square for Retail. The system will seamlessly detect membership through payment card fingerprints, support various membership types, and include an admin portal for enrollment and management. The high-level flow involves staff creating Square customer profiles, registering members, detecting fingerprints, mapping to memberships, and applying discounts during checkout. The system will utilize Square APIs like webhooks, Payments API, Customers API, and Orders API for seamless integration. The backend data model will include tables for memberships, member identities, payment fingerprints, discount rules, and events audit to ensure smooth operations and tracking. For the discount logic, the system will prioritize active memberships, apply one discount per order by default, and support optional rules like category restrictions and max discounts. The admin/ops requirements will be fulfilled with a role-based web portal for membership management, fingerprint linking, viewing logs, and exporting CSV logs. I suggest a budget range of £250 - £400 for the project, with a duration of 15 - 20 days for completion. I look forwa

@forgeahead

Hi, I’ve carefully reviewed your project brief and have direct experience building Square API–integrated middleware, real-time webhook processors, and secure admin portals for retail workflows. This project aligns perfectly with my expertise in Node.js/Python backends, PostgreSQL data modeling, and PCI/GDPR-compliant payment handling. Here’s how I can deliver your MVP within scope: -Square API/Webhook Integration -Membership & Family Plan Logic -Pre-Payment Discount Injection -Secure Admin Portal -Edge Case Handling Tech Approach: -Backend: Node.js (TypeScript) + Express or Python (FastAPI) -DB: PostgreSQL with unique fingerprint constraints Infra: AWS Fargate/Lambda with HTTPS, WAF, and OpenTelemetry monitoring -Admin UI: React or lightweight Vue with secure JWT authentication Questions before starting: -Do you already have Square Catalog discount objects created, or should I provision them? -Is a staging Square account available for UAT before production rollout? -Do you want full-feature family membership support in MVP or phase it in later? -Will the admin portal require multi-language support? I can start immediately and aim to deliver a tested, documented MVP within your performance targets. Let's connect and discuss about this!!
