Stock Availability Indicator, UI Integration & MOQ Logic Implementation

We're looking for a developer to implement a stock availability indicator with UI integration and minimum order quantity (MOQ) logic across our web platform. All tasks are bundled into a single fixed-price contract of $200 USD, paid as one milestone upon completion. What needs to be done: 1) Stock Availability Indicator - Backend and CRM ($130): Build the backend logic to track and expose product stock status. Integrate the stock state into the CRM so that product records display real-time or near-real-time availability. The backend should support per-product stock flags, handle edge cases (out of stock, low stock), and expose the status via the existing data layer. 2) MOQ Logic Implementation ($70): Implement minimum order quantity rules on the product and ordering side. Enforce that orders below the defined MOQ threshold are blocked or flagged with a clear message to the user. MOQ values should be configurable per product and enforced at both the UI and backend levels. Deliverables: - Backend stock indicator logic with CRM integration. - Frontend UI showing stock status on relevant product pages. - MOQ enforcement with per-product configuration and clear user-facing messaging. - Brief notes explaining what was changed and where. Timeline: roughly 4 to 6 business days total. Revisions: up to 2 rounds of revisions per task within original scope, included. IP and Confidentiality: All code becomes our property upon final payment. Contractor agrees not to share or reuse the codebase or business logic. Ideal candidate: Intermediate full-stack developer comfortable with PHP, JavaScript, and web-based CRM interfaces. When applying, please briefly mention similar inventory or ordering logic work you've done.
