Custom Retail Platform Development

I’m seeking an experienced development team to build a retail platform under my own brand, with all the features of Shopify and Lightspeed Retail, plus custom functionality. I need a software platform with all the features of Shopify, Shopify POS, and Lightspeed. We will use it across our businesses and sell subscriptions to other companies, each with a separate, secure account. Required capabilities: Ecommerce, POS, offline selling, inventory, purchasing, shipping, returns, wholesale, and multi-store management. Fingerprint clock-in/out with notifications. Camera integration and cash drawer opening/closing alerts. Employee logins showing only their own sales, with management-controlled reporting dates. Live sales updates with timestamps down to the second. Inventory alerts, store transfers, best-seller reports, sales, live transaction notifications. Automatic staff bonuses, commissions, and customer loyalty points. Custom financial reports showing net sales and net profit. International payment integrations and multiple currencies. Subscription billing and an owner dashboard. Our company must own the custom source code and data, control hosting accounts, and receive full documentation. Please provide relevant project examples, your recommended technology, phased timeline, itemized pricing, and ongoing support costs. Include a feature comparison against agreed Shopify and Lightspeed plans, identifying integrations and hardware limitations. We are seeking a long-term partner, starting with discovery and a pilot in our stores.
