Custom Retail POS System Development - 29/08/2026 10:22 EDT

# Senior POS Developer / Architect Needed – Custom Retail POS Platform I am looking for an experienced **POS software developer or development team** to build a custom retail Point-of-Sale system from the ground up. The initial system will be used in my own retail stores, but the long-term goal is to develop this into a **commercial POS platform that can eventually be offered to other businesses**. ### General Requirements The system should include: * Modern, fast retail POS interface * Product and inventory management * Barcode scanning * Employee accounts and permissions * Cash register management * Sales, returns, refunds and discounts * Customer management * Receipt printing * Reporting and analytics * Multi-store support * Cloud-based administration * Reliable synchronization between locations/registers * Integration with POS hardware such as barcode scanners, receipt printers, cash drawers and payment terminals ### Payment Processing A major part of the project will be **integrated credit/debit card processing**. I want the POS to communicate directly with a compatible payment terminal so the cashier can initiate a transaction from the POS and the customer can tap/insert/swipe their card on the terminal. The payment architecture should be flexible enough to potentially support **multiple payment processors in the future**. Long term, I am interested in developing a business model where the platform could potentially generate revenue through: * POS subscriptions * Hardware * Payment processing * Additional software/services Experience with payment processors such as **Square, Stripe, Adyen, Fiserv, Worldpay, Global Payments, Clover**, or similar platforms is highly desirable. ### Long-Term Architecture The system should be designed with future growth in mind, including: * Multiple businesses/merchants * Multiple locations * Multiple registers * Cloud administration * Multi-tenant architecture * Payment integrations * Merchant onboarding * Third-party integrations * Scalable infrastructure ### Development Approach I would like to begin with a **paid discovery/architecture phase**. I will provide an existing POS system as a **functional reference** so the developer can understand the type of workflow and functionality I am looking for. The first phase should determine: * System architecture * Technology stack * Database structure * Payment architecture * Hardware integration * Development roadmap * Estimated cost and timeline After the architecture phase, I would like to move into full development with the right developer/team. ### Who I Am Looking For I am specifically looking for someone with **real-world POS development experience**, not just general web development. Ideal experience includes: * Retail POS * Inventory systems * Payment processing * Payment terminals * POS hardware * Multi-location systems * Cloud/SaaS platforms * APIs * Multi-tenant applications * Security and payment compliance Please provide examples of **POS systems you have personally built or worked on**, including any payment terminal integrations. I am looking for a **long-term development partner**, not just someone to complete a quick project
