I sell across Amazon and Shopify and keep stock in several separate locations, so I’m ready to replace the spreadsheets and mismatched apps with a single, purpose-built inventory management platform. Core scope The software must pull products, orders and stock levels from both Amazon (SP-API) and Shopify, then push automated stock updates back to each channel in near real time. I also need a clear sales-analytics dashboard so I can spot fast movers, slow sellers and margin trends without exporting CSVs. Because my units sit in more than one warehouse, the system has to allocate stock by location, let me transfer it internally and prevent overselling by combining totals where appropriate. Reporting Daily and weekly snapshots should be generated automatically, while a flexible report builder lets me choose custom date ranges, SKUs or warehouses on demand. Deliverables • Fully functional web app (responsive UI) • Modules for multi-warehouse management, sales analytics and customizable reporting • Source code in a private repo plus a brief hand-over call or video walkthrough I’m happy to hear your recommendations. Please outline relevant experience with this type of software, proposed timeline and any questions you need answered before starting.

Hello Valuable Client, CnEL India can build a centralized inventory platform that keeps Amazon, Shopify and multiple warehouse locations synchronized through a reliable API-driven architecture. Our methodology: • Connect Amazon SP-API and Shopify to securely pull products, orders and inventory data. • Normalize SKU/product data into a centralized database with clear warehouse-level stock records. • Implement near-real-time stock synchronization with controlled update queues, retries and error logging. • Build multi-warehouse allocation and internal stock-transfer workflows while applying overselling safeguards. • Develop analytics for sales velocity, fast/slow movers and margin trends without requiring CSV exports. • Automate daily and weekly snapshots and provide a flexible report builder for dates, SKUs and warehouses. • Create a responsive dashboard for inventory, orders, synchronization status and reporting. • Test synchronization, stock adjustments, transfers and edge cases before production deployment. • Deliver the complete source code in a private repository with documentation and handover. We would first validate the Amazon/Shopify data flows and inventory rules, then build the platform incrementally around them. Best regards, CnEL India

I’ll begin by designing a unified inventory schema that maps Amazon and Shopify product IDs to internal SKUs and warehouse locations, then build a Node.js service that pulls product, order, and stock data from SP‑API and Shopify Admin API into PostgreSQL. From there, I’ll implement real‑time stock updates, multi‑warehouse allocation, and a responsive Angular dashboard for sales analytics and reporting. I’ve built a similar multi‑warehouse ERP with Angular/Node/Postgres at app.dawaadost.com. I can deliver the full web app in 45 days. Do you need real‑time push updates to Amazon and Shopify, or is a 5‑minute interval acceptable?

Hello, This inventory platform needs to become the single source of truth between Amazon, Shopify, and multiple warehouse locations not just another stock dashboard. I’ve already developed inventory software with multi-channel synchronization, stock management, warehouse workflows, order processing, and reporting, so I understand the importance of keeping inventory accurate while preventing overselling across channels. I can build a responsive web application integrating Amazon SP-API and Shopify to synchronize products, orders, inventory and stock changes, with automated near-real-time updates back to both sales channels. The system will include multi-warehouse stock allocation, internal transfers, SKU-level inventory visibility, and intelligent availability calculations across locations. The analytics dashboard will surface fast movers, slow sellers, sales performance and margin trends, while automated daily/weekly snapshots and flexible reports will allow filtering by dates, SKUs and warehouses without relying on CSV exports. I’ll also implement reliable synchronization, error handling and reconciliation so API failures or conflicting updates don’t leave your inventory inconsistent. The complete source code will be delivered in your private repository with a handover walkthrough. Regards, Nikita Gupta

Near real-time sync between Amazon and Shopify only works reliably if Amazon is the source of truth for stock, since SP-API throttles harder than Shopify's webhooks. I'll build the app on Laravel with a React dashboard, wire SP-API and Shopify webhooks into a central stock ledger keyed by warehouse, and add the report builder with scheduled snapshots. I can start right away. 1) How many SKUs and warehouses, and do any share pooled stock? 2) Any existing FBA inventory to treat separately from your own locations? Thanks Shayan

Managing stock across Amazon and Shopify with multiple warehouses is a nightmare of race conditions and API rate limits. We build and actively maintain these exact bidirectional sync engines for high-volume sellers. Because we have done this multiple times, we can deliver this purpose-built platform for you in just 2 weeks. Here is our strategy to keep costs down and quality high: Private SP-API Integration: Instead of building a generic public app that requires months of Amazon compliance audits, we will configure a Private SP-API integration using your direct seller credentials. This is significantly cheaper, highly secure, and lets us pull your Amazon data immediately. The Sync Engine: We will wire Shopify webhooks and Amazon SP-API to a central database. It will automatically push near real-time stock updates to both channels to definitively prevent overselling. Multi-Warehouse Routing: The system will treat your various locations as independent nodes, allowing you to seamlessly log internal transfers and allocate specific stock pools to specific sales channels. Analytics Dashboard: We will build a clean, responsive UI that generates your daily snapshots, highlights fast movers, and calculates true margins without you ever needing to export a CSV again. I am ready to review your current warehouse setup and get this engine built. Let's talk.

Hi, I build full-stack applications with real-time API integrations and multi-source data sync, which is exactly what this inventory platform needs. My approach: Integrations — Connect to Amazon SP-API and Shopify to pull products, orders, and stock levels, with near-real-time push-back of stock updates to both channels Multi-warehouse logic — Stock allocation by location, internal transfer capability, and combined-total logic to prevent overselling across warehouses Sales analytics dashboard — Live view of fast movers, slow sellers, and margin trends, no CSV exports needed Reporting — Automated daily/weekly snapshots plus a flexible report builder for custom date ranges, SKUs, or warehouses Architecture: Responsive web app (PHP or Node.js backend, MySQL) with modular structure so warehouse management, analytics, and reporting can evolve independently. Delivery: Source code in a private repo, plus a hand-off call/video walkthrough covering how everything fits together. On timeline: Given the scope (two-platform sync + multi-warehouse inventory logic + analytics), I'd suggest we align on priorities first — likely starting with the Amazon/Shopify sync core, then layering in warehouse allocation and reporting — so you see working functionality early rather than waiting for everything at once. Happy to discuss further and answer any questions before we start.

Hi, I can build this custom multi-channel inventory management platform for Amazon and Shopify, with centralized inventory and multi-warehouse support. I have experience developing custom management systems using Laravel, MySQL, REST APIs, dashboards, reporting, and automated background processes. Key features I can develop: * Amazon SP-API + Shopify integration * Centralized inventory and SKU management * Multi-warehouse stock tracking and transfers * Automated stock synchronization * Product and order synchronization * Overselling prevention with stock allocation/reservation * Sales, fast/slow-moving product and margin analytics * Daily/weekly automated reports * Custom reports with SKU, warehouse, and date filters * Responsive web dashboard * Sync logs, error handling, and audit history I would use Laravel + MySQL with queues and scheduled jobs for reliable synchronization and a scalable architecture. Estimated timeline: 2 -10 weeks, depending on the number of SKUs, orders, warehouses, and exact Amazon requirements. Before starting, I’d like to confirm the number of Amazon marketplaces, Shopify stores, warehouses, and approximate monthly order volume. I can provide the complete source code in a private repository along with a handover walkthrough. Thanks!

Hi there, The hardest part of your inventory platform isn't the dashboard—it’s keeping Amazon, Shopify, and multiple warehouses synchronized without overselling or creating conflicting stock. I understand you need: • Amazon SP-API + Shopify product/order/stock synchronization • Near-real-time inventory updates in both directions • Multi-warehouse allocation and internal transfers • Overselling prevention and reliable stock calculations • Sales analytics, scheduled snapshots, and flexible reporting • Responsive web app with private-repo source and handover My approach: 1. Design a centralized inventory model with SKU/channel/warehouse mapping. 2. Integrate Amazon SP-API and Shopify using webhooks + scheduled reconciliation. 3. Implement stock reservation/locking and warehouse allocation to prevent race-condition overselling. 4. Build analytics and report generation around the normalized data. 5. Add logging, retry handling, sync monitoring, and end-to-end testing. I have experience with PHP, JavaScript, MySQL, REST APIs, web applications, automation, and database-driven systems, and can structure this for future channel expansion. A few questions: 1. How many SKUs and warehouses do you currently manage? 2. Do you need FBA inventory included alongside your own warehouses? 3. Is the ₹37,500 ceiling intended for a complete MVP or the entire production system? Once these are confirmed, I can provide a realistic milestone plan and timeline. Best regards, Ankit

Amazon and Shopify stock, several warehouses, and sales you can read without a spreadsheet. I can start right now. In 24 to 48 hours you get a live sample: your products, orders, stock by location, and fast movers on one screen. Then auto stock updates so neither shop oversells, warehouse transfers, daily and weekly snapshots, and a report by date, SKU, or warehouse. Source code and a short walkthrough are yours. I ship live systems with logins, timed jobs, and dashboards. Amazon’s seller link is the part I prove first on your account. Share both shop access and your warehouse list so I can start the live sample?

Your inventory platform needs to solve one hard problem well: keeping Amazon, Shopify, and multiple warehouses synchronized without overselling. I’d build the system around a centralized inventory service, with Amazon SP-API and Shopify integrations feeding into one source of truth, then pushing stock changes back automatically. My approach: Centralized SKU/inventory database with warehouse-level quantities Amazon SP-API + Shopify product/order/inventory synchronization Near-real-time stock updates with retry/error handling for API failures Warehouse transfers, allocations, reserved stock, and overselling protection Sales dashboard for fast/slow movers, revenue, costs and margin trends Automated daily/weekly snapshots Custom reports by date range, SKU and warehouse Responsive web UI with role-ready architecture Private Git repository + handover walkthrough For reliability, I’d also keep an inventory transaction/audit history so every stock adjustment and channel update can be traced rather than relying only on the current quantity. Estimated timeline: 4–6 weeks for a solid first production version, depending mainly on the number of warehouses/SKUs and the exact reporting and margin requirements.

Hi, I can build a purpose-built inventory management platform that connects Amazon and Shopify into one centralized system, replacing spreadsheets and disconnected tools. The platform can include: • Amazon SP-API and Shopify integration for products, orders and inventory • Near real-time stock synchronization across both channels • Multi-warehouse inventory with location-wise stock tracking • Internal stock transfers between warehouses • Automated stock allocation and overselling prevention • Sales dashboard showing fast/slow movers, sales trends and margins • Automated daily and weekly reports • Custom report builder with date, SKU and warehouse filters • Responsive web interface with a clean, easy-to-use dashboard • Secure API handling, logging and error monitoring • Private Git repository with complete source code and documentation I’ll structure the system in a modular way so additional marketplaces, warehouses or reporting features can be added later without rebuilding the platform. I can first map the Amazon/Shopify data flow and warehouse rules, then develop the integrations, inventory engine, analytics and reporting modules in milestones. Please share your current SKU/warehouse structure and any existing API setup so I can suggest the best architecture, timeline and fixed-price estimate.
