I need a single, web-based CRM that pulls together three core functions for my business: • Sales tracking – real-time dashboards, pipeline stages, and downloadable reports that let me slice data by product, rep, and date range. • Stock control – live inventory counts with low-stock alerts and the ability to adjust quantities manually or via barcode scan. • Customer invoicing – branded PDF invoices, automatic numbering, tax calculation, and payment status updates. Role-based access is essential. Administrators must see and edit everything, sales reps should handle their own leads and quotes, while warehouse staff need inventory screens only. Please build these levels so I can change permissions later without code edits. The system must run in any modern browser and be responsive on tablets. Clean UI, quick loading, and secure login (HTTPS, hashed passwords) are non-negotiable. While there are no mandatory third-party integrations right now, keeping the architecture open for future links to email, accounting, or payment APIs will be a plus. Deliverables 1. Deployed web application with the three modules fully functional. 2. Source code and database schema. 3. Short admin guide covering user management, backups, and basic configuration. 4. A one-hour hand-over call or video to walk through the setup. I’ll test by creating sample users, entering dummy sales and inventory data, and generating an invoice. Everything should display correctly across Chrome, Edge, and Safari. Let me know the framework you plan to use, your estimated timeline, and any similar projects you’ve delivered. This contest for existing solutions with or with our user based, SaaS or non SaaS based as well. In case you have a a code based solution then feel free to contest but offer a well explained solution in chat. No diagrams.

control, and invoicing in one place, rather than as three disconnected tools. The key is to keep the system simple for day-to-day use while structuring the data model correctly so sales, inventory, and invoices remain consistent with each other. My recommendation would be to build this as a responsive web application with a clean internal UI, role-based access that can be adjusted from the admin side, and a modular architecture so future integrations with email, accounting, or payments can be added without reworking the core. The most important part is not only having dashboards and forms, but making sure pipeline stages, inventory movements, invoice generation, tax logic, and permissions behave coherently across the whole system. Given the budget and your note that existing/code-based solutions are welcome, I would approach this in the most practical way possible: either by starting from a strong internal foundation that already covers part of the workflow, or by delivering a focused custom V1 with the three modules you described, keeping the implementation clean and extendable. That gives you a usable system quickly, without overengineering the first release. Nico – widuIT - Top Freelancer LATAM

Hello, I sense you’re aiming for a single, secure, future-proof CRM that unifies sales, stock, and invoicing, without compromising speed or user experience. I’m Asad, and I’ve led several end-to-end CRM builds using ASP.NET and MySQL, delivering real-time dashboards, barcode-enabled stock control, and auto-generated branded invoices with tax calculations. I’ll design a clean, responsive UI that runs smoothly in Chrome, Edge, and Safari, with role-based access that’s easy to tweak later without touching code. The system will be modular from day one, so you can add email, accounting, or payment integrations later without architectural churn. Deliverables include a deployed app with all three modules, source and DB schema, a short admin guide, and a 1-hour handover call. I’ve shared an initial estimate based on your description, and once we go over a few technical details, I’ll confirm the exact cost and delivery schedule. What is your preferred RBAC approach for future permission tweaks (e.g., granular per-module roles), and do you have any existing data migration considerations or formats I should plan for? Best regards, Asad

Hi I can provide a web-based CRM solution that unifies sales tracking, stock control, and invoicing in one responsive system with clean role-based access management. A major technical issue in this type of platform is keeping permissions, inventory updates, and invoice data consistent across different user roles without creating security or data integrity gaps. I solve this by building a modular architecture with RBAC, secure authentication, and clearly separated sales, warehouse, and admin workflows that remain easy to expand later. The CRM will include real-time dashboards, filterable reporting, live stock updates with alert logic and barcode-ready input flow, plus branded PDF invoicing with numbering, tax handling, and payment status tracking. I would use a robust stack such as React with Node.js/Express or Laravel, backed by PostgreSQL or MySQL, depending on your preference for scalability and maintainability. The UI will be optimized for modern browsers and tablets, with HTTPS, hashed passwords, and a codebase structured for future API integrations like accounting, email, or payments. I can also present an existing solution approach clearly in chat and adapt it to your required modules and permission model. Thanks, Hercules

Hello, I’m excited about your project for developing a comprehensive web-based CRM that merges sales tracking, stock control, and customer invoicing. With over five years of experience in designing and deploying similar solutions, I understand the importance of a clean UI and secure architecture. To tackle this project, I propose using ASP.NET with a MySQL database to ensure robust performance and scalability. The CRM will feature real-time dashboards, live inventory counts, and branded invoices, all while allowing role-based access control for administrators, sales reps, and warehouse staff. One improvement idea is to add data export options for inventory and sales, enabling better reporting. I recently completed a similar CRM for a retail client, enhancing their inventory management and sales processes. I anticipate a delivery timeline of about 6 weeks. Regards, Khurshid Ahmed

My toolkit spans the full creative spectrum: WordPress, Shopify, HTML/CSS/JS, PHP, Laravel, Figma, Photoshop, and Illustrator.

Hi Abid K., Just last week I completed a similar task successfully, so I can get started on this without any ramp-up time. How should tax be calculated (single rate, per product, or by customer location), and do you need separate invoice numbering sequences per brand/branch? For inventory, is it single or multi-warehouse, and should barcode scanning use device cameras (BarcodeDetector/QuaggaJS) or dedicated USB scanners? Suggestions: Use policy-based RBAC with DB-stored permissions and an admin UI so you can change access later without code; power real-time dashboards from read-optimized tables/materialized views with WebSocket pushes for speed. Architect a modular REST API (NestJS + PostgreSQL) with versioned endpoints and an event outbox to keep future integrations reliable. Action Plan: - Stack: React (TypeScript) + NestJS + PostgreSQL; Auth: HTTPS, Argon2, JWT (HttpOnly); PDFs: Puppeteer. - Phase 1 (3–4d): confirm workflows, fields, invoice template, role matrix. - Phase 2 (1.5w): auth/RBAC, users/roles, audit; responsive UI shell. - Phase 3 (1.5w): Sales (pipeline, filters by product/rep/date, exports) + real-time dashboards. - Phase 4 (1w): Inventory (counts, adjustments, low-stock alerts, barcode). - Phase 5 (1w): Invoicing (branding, numbering, tax, statuses, PDFs) Best Regards, Sid

Hello from sunny South Africa. While I can source and install a CRM that will work for you it will be better to build one. CRMs are one of the drivers of your business and you should not have to deal with something thats forced to fit. We start with the three Sales Tracking, Stock control, and Customer Invoicing you have defined but leep it scalable so we can add as many other modules as needed. Yes role based with permissions is a must. THis is the kind of thing I live to do. It will be perfect. Please contact me for a link to my portfolio and I can all do a video call with screenshare and walk you through similar projects I have created.

Hi there, The risk with multi-module CRMs is "Data Fragmentation"—where your stock counts and sales invoices fall out of sync because the database wasn't architected for real-time reconciliation. I don’t just build "screens"; I architect robust relational systems that ensure when an invoice is generated, your inventory reflects the change instantly and securely. I specialize in building custom, web-based platforms with Role-Based Access Control (RBAC). I’ll ensure your Admin, Sales, and Warehouse staff see exactly what they need—and nothing they don't—through a clean, high-performance UI optimized for both desktop and tablet. My Execution Strategy for your CRM: Relational Architecture: I’ll use a MySQL/PostgreSQL backend to handle the complex handshake between Product IDs, Sales Reps, and Stock Levels, ensuring 100% data accuracy. The "3-Module" Sync: I’ll build a unified dashboard where Sales Pipelines feed directly into the Invoicing engine, with automated tax calculations and low-stock triggers. Secure & Scalable Build: I’ll implement HTTPS and hashed password protocols from day one, using a modular framework (like ASP.NET or Laravel) that allows for future API links to accounting or email tools. Experience: I’ve delivered similar SaaS-style platforms focusing on inventory-to-invoice workflows, ensuring "zero-leakage" in stock management. Best regards, Waqas Ahmad

Recent similar work: I helped a mid-size distributor deploy a three-module CRM for sales, stock, and invoicing. They saw faster invoice creation and closer stock control, reducing cycle time by about 40%. Let's chat - I can walk you through my approach in 15 minutes.
