The project centers on tailoring our existing ERP so the HR, Inventory, and Finance modules align perfectly with the way we work. ERP Version & Platform Constraints - Version & Environment: Target environment is Odoo (v16 / v17) running on a self-hosted cloud VPS / [login to view URL] environment. - Architectural Rules: All customizations must strictly follow standard Odoo module inheritance and ORM guidelines (no modifying core source files) to maintain database integrity and ensure seamless future version upgrades. - Performance Boundary: Dashboard queries must rely on indexed PostgreSQL custom views or clean ORM methods to avoid slow load times on heavy transactional data ([login to view URL], [login to view URL], [login to view URL]). Hybrid Focus (40% New Feature / 60% Module Optimization): New Feature Development (40%): - Building the Supplier Performance Dashboard module from scratch (custom SQL data views, backend models, and front-end dashboard UI). Optimization & Customization (60%): - Enhancing existing native modules (HR, Inventory, and Finance) by adding custom fields, configuring automated workflow triggers, and building custom reporting templates. Across all three areas you will: • Write clean server-side scripts and front-end tweaks that slot into the current ERP framework. • Expose or consume REST/JSON APIs where integration with third-party services is needed. • Build automated workflows that eliminate manual hand-offs. • Produce flexible reporting templates the team can edit without code. • Test every scenario, squash regressions, and document configuration choices, code changes, and deployment steps in clear English. Deliverables (acceptance criteria) 1. Updated HR, Inventory, and Finance modules running in our staging environment with all enhancements enabled. 2. Source-controlled scripts, API connectors, and workflow definitions. 3. Test log proving core use-cases pass and no existing function is broken. 4. A concise technical handbook covering setup, maintenance, and rollback. The current instance is live, so careful version control, rollback planning, and clear communication are essential throughout the engagement.

Hi, I understand this is an ERP customization project, not a rebuild. The priority is to connect HR, Inventory and Finance workflows so employee, procurement, stock and financial data work together without disrupting the live system. I have 13+ years of experience with ERP customization, backend scripting, REST APIs, workflow automation, databases and reporting systems. I’ll handle: • HR onboarding → payroll → performance management integration • Inventory rules and automated PR → PO → receipt workflows • Supplier dashboard with real-time KPIs • Finance chart of accounts and cost-center customization • Cross-module approval workflows and data synchronization • REST/JSON API integrations • Editable reporting templates • Staging-first development with Git/version control • Regression testing, rollback planning and deployment documentation I’ll first audit the existing ERP framework and current workflows, then implement changes incrementally in staging before production deployment. I can provide milestone-based delivery, complete source-controlled changes, test evidence and a concise technical handbook. Let’s review the current ERP stack and existing HR/Inventory/Finance workflows to finalize the implementation plan.

Hi, I’m interested in your ERP customization project and understand the main priority is protecting HR, Inventory, and Finance flows while new rules are integrated. My approach would be to first map the current module logic, then implement changes in a staging branch with version control and rollback safety before any production update. I can support the onboarding-to-payroll flow, stock-to-purchase automation, approval logic, COA and cost center adjustments, server-side scripts, REST/JSON integrations, and front-end changes. I’ll also make reporting templates editable without affecting the core codebase. Initial focus: Review current HR, Inventory, and Finance workflows Extend onboarding and payroll handoff Refine stock and purchase automation Adjust COA, cost centers, and approvals Run regression testing on core cases One question: are these custom workflows already available in the existing ERP codebase, or will some require new API endpoints and database tables? I’m available to discuss this through Freelancer chat or video call between 11 AM and 8 PM IST. Please share the current setup, and I can outline the safest implementation plan.

I’ve worked on complex system customizations where multiple modules need to stay in sync without breaking live operations, and your ERP scope fits that well. The HR, Inventory, and Finance dependencies here need careful scripting, workflow design, API handling, regression testing, and rollback planning, not just isolated edits. I can help implement the enhancements cleanly in staging and document everything properly so your team can maintain it later. If you want, I can also outline the execution phases clearly before we begin.

Hi there, I understand you need comprehensive ERP customization for your HR, Inventory, and Finance modules to match your operational workflow. Your focus on extending the employee onboarding process and creating tight integrations between modules is clear. My approach involves analyzing your current ERP architecture to identify customization touchpoints. For the HR module, I'll develop automated onboarding workflows with document management, approval processes, and data synchronization across departments. The Inventory integration will include real-time tracking, automated reordering, and multi-location management. For Finance, I'll create automated reporting, expense tracking, and budget allocation features. I'll leverage AI-driven automation for repetitive tasks, ensure robust network security throughout the implementation, and provide comprehensive documentation for future maintenance. My experience includes similar ERP customizations where I've successfully automated manual processes, reducing operational overhead by 40-60%. The system will include proper user access controls, audit trails, and seamless data flow between all three modules while maintaining security standards. Best Regards, Khorshed Alam, RS Software

The real job is making the HR, Inventory, and Finance ERP modules all talk to each other and also to how you actually work. I will build out the employee onboarding, connecting it to payroll and also adding a performance layer pulling from HR and Finance data. Inventory stock rules get refined, with automated order processing from request to receipt, also building a supplier dashboard showing real-time KPIs. For Finance, charts of accounts, cost-center allocations, and approval flows will be adjusted to match the custom HR and Inventory logic. This means writing server-side scripts and front-end tweaks that integrate with the current ERP framework. I will not offer a full module rebuild; we will customize and automate existing ones. One thing not clear is the exact data structure for performance metrics. 8 reviews on here, everything delivered on time and on the agreed price so far, plus Preferred Freelancer status. Send over the current ERP documentation, and I will send back a detailed technical approach with a timeline.

Hello, "Custom ERP Module Scripts & Automated Workflows" - you need HR, Inventory, and Finance modules tailored and automated. I’ll extend the onboarding and inventory flows using Python/Node.js scripts that run as background jobs, keeping the UI responsive; I’ll store changes in version‑controlled Git and use Docker containers for easy rollback. I automated a similar cloud‑backup workflow with API calls and scheduled jobs: https://www.freelancer.com/projects/automation/Automate-Reolink-Video-Backup-Script/reviews To keep data consistent across modules, I’ll wrap the HR‑Finance and Inventory updates in database transactions, so any failure rolls back all related changes automatically. Do you have existing API documentation for the current ERP system, or should I start by reverse‑engineering the endpoints? Looking forward to working with you. Artur Giżycki

Hi, I can customize your existing ERP across HR, Inventory and Finance without disrupting the workflows already running in production. The important part is treating the three modules as connected processes rather than making isolated changes. Approach: • Map existing workflows and dependencies • Extend HR onboarding and payroll logic • Connect performance data with Finance • Refine inventory and purchasing workflows • Build supplier KPI reporting • Align Finance with HR and Inventory transactions • Add APIs and automation where required • Develop on staging with version control • Test regression scenarios before release What I will deliver: • Updated HR, Inventory and Finance modules • Workflow automation • REST/JSON integrations • Editable reporting templates • Source-controlled changes • Test and regression log • Deployment and rollback documentation Because the current ERP is live, I’ll avoid direct production changes during development. Each change will be traceable, tested in staging and prepared for controlled deployment with a rollback path. I can first review the current ERP version, custom modules and existing workflows, then provide a practical implementation plan and milestones. Regards, Shubham
