Hi, I've worked on similar WMS, inventory, logistics, and ERP systems, including inward/outward workflows, warehouse inventory, stock tracking, and database-driven business processes. We’re also comfortable extending existing CodeIgniter/PHP systems rather than rebuilding them. For your Perfex CRM, I’d first review the existing codebase, database relationships, and operational workflows on staging, then implement the WMS features phase-by-phase. I’ll take backups before changes, preserve existing data/modules, document database changes, and thoroughly test each workflow before deployment. The box-level Actual/Volumetric/Chargeable Weight logic will also be handled correctly, including aggregation and the higher-value rule. I can personally handle the development and provide source code, modified-file lists, documentation, and staging-to-production deployment support. I’d be happy to review the current system and provide a realistic timeline after understanding the existing customization. Thanks

Hi, I have 10+ years of experience with PHP, CodeIgniter, MySQL, CRM/ERP and database-driven applications. I’m comfortable customizing existing Perfex CRM codebases without rebuilding or disrupting operational data. I can handle WMS workflows, inventory, PO/Gate-In, box-level weight calculations, warehouse locations, permissions and reporting. I’ll work on staging, take backups, review dependencies first, and provide clean, unencrypted source code with testing and documentation. Perfex supports modular CodeIgniter-based extensions, which fits this approach.

@jayantkumar314

Hi, I carefully reviewed your WMS requirements. The key point I understand is that this is an existing Perfex/CodeIgniter system with live operational data, so the goal should be to extend the current functionality safely rather than rebuild it. I would first review the existing codebase, database relationships and current workflow on staging, with a complete backup before making any changes. I can work phase-by-phase on Supplier/PO mapping, Booking & Gate-In improvements, inward workflow, box-level inventory, warehouse/rack/location management, damage/repacking, outbound orders, reports and role-based visibility. I also understand your weight rule: each box must maintain Actual and Volumetric Weight, while Chargeable Weight must always use the higher value and aggregate correctly where required. My experience includes PHP, MySQL, MVC applications, APIs, admin/CRUD systems and debugging existing database-driven projects. I am comfortable understanding an existing customized codebase and implementing new business workflows carefully. I will work personally on the project, test each phase on staging, document database changes and provide all modified source files. I’m ready to start with a code/database review and then confirm the implementation milestones and timeline.

@jagratip3

Hi, I’m an experienced PHP/CodeIgniter backend developer with strong expertise in working with existing, customized CRM/ERP codebases rather than rebuilding systems unnecessarily. I’m comfortable with Perfex CRM, MySQL, JavaScript/AJAX, inventory, warehouse, logistics, and database-driven workflows. I can extend your current WMS safely across Supplier/PO mapping, Booking, Gate-In, inward/outward workflows, box-level inventory, dimensions, volumetric/chargeable weight, warehouse locations, damage/repacking, delivery orders, reports, and role-based visibility. I’ll work strictly on staging first, take verified backups, analyze existing relationships, make incremental changes, document migrations, list modified files, and test complete workflows before production. Existing data and working modules will not be deleted or disturbed. I personally handle development and can work phase-by-phase after reviewing the current codebase. I’m ready to begin with a technical audit and provide a realistic timeline after assessment.

@accelaronix

Hi, I can extend your existing Perfex/CodeIgniter WMS without rebuilding what already works. My first priority would be understanding the current codebase, database relationships and operational workflows so new functionality can be added without risking existing data. **Approach:** • Review codebase and database • Take verified backups • Work phase-by-phase on staging • Extend existing modules where practical • Build box-level inventory workflows • Implement accurate weight calculations • Connect inward, storage and outbound flows • Test database and workflow integrity For the weight logic, I would centralize the calculation so Chargeable Weight always uses the higher of Actual and Volumetric Weight, both at box level and wherever shipment totals are required. **What I will deliver:** • WMS enhancements • Safe database changes • Source code • Modified-file list • Database documentation • Staging-tested workflows • Production handover I’m comfortable working with existing database-driven systems where preserving current functionality is critical. I can first review your Perfex version, custom modules and database structure, then provide a realistic phased timeline. Regards, Shubham

Judge me on an audit before I touch your database. Day two you get an ER diagram of your current schema, a list of every core Perfex file already customised in your install, and a fixed price per module. If it doesn't convince you, stop there and keep it. After that, everything goes in as a Perfex module under application/modules with its own migrations and hooks, never edits to core files, because those get wiped on the next Perfex update. Supplier Master and PO Master come first since the mapping, the BR changes and all four documents reference them. Additive migrations only, each with a working down(), a full mysqldump before every run, staging clone before production. You get unencrypted source, a modified-files list and a short README. E-Way Bill is the fork worth settling now. Capturing the fields and printing them on invoice, challan and docket sits inside this phase. Live generation through the NIC/GSP API is separate work, needs your GSP credentials and a sandbox cycle, so I would quote that off the audit instead of guessing at it here. Straight about my record: 3 reviews on this account, 100% completion, 97% on time. My backend work is the DKERPS file-sharing platform plus PHP/MySQL and Python full-stack contracts, not Perfex specifically. That is exactly why the audit comes first, so you decide on a real deliverable rather than on my word.

I can help extend your existing Perfex CRM/CodeIgniter WMS safely, without disrupting live operations. My approach is to first review the current database, workflows, and custom modules, then implement changes in phases on your staging server with backups before every change. I’ll focus on the logistics and ERP flow you described: customer→supplier→PO mapping, booking request improvements, gate-in matching, inward tasks, box-wise inventory, rack/location tracking, damage reporting, repacking, packing list, outbound delivery flow, and the chargeable weight logic where Actual Weight vs Volumetric Weight always resolves to the higher value at box and aggregate level. I work carefully with existing codebases, document database changes, provide source code and modified file lists, and test the full workflow before handover. Which Perfex CRM version and staging access details can you share for the initial codebase audit? If helpful, I can start by auditing the current Perfex structure and then give you a phased implementation plan after review. Imran

Hi, I can enhance your existing Perfex CRM / CodeIgniter WMS safely without rebuilding or disturbing current operational data. I will first review your existing codebase, database structure, active modules, booking flow, Gate-In process, inventory flow, and staging setup. Then I’ll work phase by phase, take backups, document database changes, and extend the current system carefully. I’m comfortable with PHP, CodeIgniter, MySQL, JavaScript/AJAX, Perfex CRM customization, logistics workflows, inventory systems, inward/outward processes, warehouse/rack/location tracking, PO mapping, reports, permissions, and ERP-style modules. I can add or improve Supplier Master, PO Master, Booking Request, Gate-In matching, inward task flow, unloading, box-wise inventory, dimensions, actual weight, volumetric weight, chargeable weight logic, damage reporting, repacking, packing list, outbound/delivery order, stock reports, and role-based rate/amount visibility. To protect your existing data, I will work only on staging first, take backups before changes, avoid deleting data, provide all source code, share the modified file list, document DB changes, and test the full workflow before handover. I’ll focus on safe enhancement, clean database handling, and reliable WMS workflow improvements. Best regards Ankit

@Ashoksahu001

Hello, This is a strong fit for my backend/database experience because you need someone to extend a live Perfex/CodeIgniter WMS safely—not rebuild it or risk existing operational data. I bring 7+ years of PHP/backend experience with MySQL, REST APIs, database optimisation, production debugging and logistics systems. My relevant work includes a Logistics & Shipment Tracking System handling consignment lifecycle, real-time status updates, partner APIs, reconciliation jobs and delayed-shipment alerts, plus an e-commerce marketplace with transaction-safe inventory. 0 Relevant projects: • Logistics & Shipment Tracking System — REST APIs, status workflows, reconciliation, database indexing • E-Commerce Marketplace — inventory, orders, transaction-safe stock and payment settlement • CRM — workflow automation and legacy-schema migration • Analytics Platform — large-data reporting and optimised database queries 1 I’m comfortable working phase-by-phase on staging. My process would be: full code/database audit → backup → schema/relationship mapping → isolated development → workflow testing → data-integrity verification → production deployment. The chargeable-weight rule is straightforward to enforce at box level and aggregate safely using MAX(Actual Weight, Volumetric Weight), while preserving both source values for auditability.

@mikes126

Hi there , let's have short meeting if you wanna discuss your Perfex CRM warehouse build. I have customized Perfex CRM before and understand its CodeIgniter structure deeply. I will extend your existing WMS without touching working modules or deleting any data. All changes will be tested on staging first with full backups and clear documentation. I will build customer supplier PO mapping booking requests and gate in workflows. The system will handle actual weight volumetric weight and chargeable weight correctly. Box wise inventory rack management damage reporting and outbound delivery will be added. I will provide all source code with no encryption plus a list of every modified file. I have built similar WMS and logistics systems before and can share project examples.

@shaun4014

Hi, Yes, I am comfortable working with an existing customized Perfex CRM / CodeIgniter codebase and extending functionality without disrupting current operations. I have experience with PHP, CodeIgniter, MySQL, ERP, inventory management, warehouse workflows, and custom business applications. My approach would be to first review the existing database structure, modules, workflows, and customizations before proposing any changes. For data safety: • Full database and file backups before every deployment • Development and testing on a staging server only • No deletion of existing operational data • Database change scripts documented and version-controlled • Complete workflow testing before production release • Detailed list of modified files provided during handover The WMS requirements you listed—including PO management, supplier master, gate-in workflow, box-wise inventory, rack/location management, damage tracking, packing lists, delivery orders, stock reports, and chargeable weight calculations—can be implemented as extensions to the existing architecture wherever possible instead of rebuilding modules unnecessarily. The chargeable weight logic will be handled at both box and aggregate levels using: Chargeable Weight = Max(Actual Weight, Volumetric Weight) I personally handle development and can work phase-by-phase on your staging environment with regular progress updates.
