Hi Efstathios, I see the depth of your requirement for a custom web-based software that centralizes quotations, invoices, and financial tracking while giving you full ownership and control. Your detailed flow for material selection, pricing, and user roles speaks to a clear vision — I specialize in building robust, scalable web apps with PHP and database management that precisely fit such complex workflows. I will ensure the system is secure, user-friendly, and reflects your brand with clear visual elements (icons and drawings) on quotations and PDFs. Starting step-by-step, I’ll build the quotation and pricing core first, then expand into invoicing and payments per your roadmap. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. What database system do you currently prefer or have in place for hosting this software? Thanks, Asad

Hello, I’m a full-stack developer with 8+ years of experience building custom web-based business systems (quotations, invoicing, CRM, and performance dashboards). I can build your software on your own hosting with full ownership, starting from quotation creation and expanding to full financial and sales management. Workflow (in points): • Requirements confirmation: review all flows (quotation, pricing, delivery, invoices, payments, statistics) and define data models and permissions. • Architecture & setup: build a secure web app with Admin + unlimited salesperson users, role-based access control, and audit logs. • Quotation module: implement material, color, opening type, glass, and mosquito options with visual icons; calculate prices automatically using admin-managed price lists. • Delivery cost: compute based on distance and per-km rate. • Quotation management: save, export PDF, archive old versions when edited, and generate new quotation numbers automatically. • Invoice generation: convert approved quotations into invoices and send to customers via email. • Payments & receipts: support partial payments with adjustable percentages, upload bank slips, and generate receipts. • Customer financial tracking: total, paid, outstanding, and payment history. • Sales statistics: per-user and admin dashboards for closing ratios, monthly/quarterly performance, and global overview. Thanks Julian

Hi Efstathios, I am excited about the opportunity to develop a web-based software tailored to your company's needs. With a strong background in web development and experience in creating similar systems, I can ensure your software will streamline quotation creation, invoicing, and financial tracking seamlessly. The software will be designed to provide full control, allowing you to manage users, roles, and permissions effectively.

My approach will be iterative, focusing first on the quotation creation flow and gradually expanding to encompass all financial management features. I propose a timeline of 8 weeks to complete the initial phase of the project. This will include designing the core functionalities, such as real-time pricing calculations and moisture management capabilities.

I understand your requirement for a fully owned, web-based quotation, invoicing, and sales management system with role-based access, pricing logic, and performance tracking.I deliver clean, reliable, and scalable software, and can build this step by step, starting with quotation creation and automated pricing, then expanding to full financial and analytics features.I can start immediately and manage the full process from system design through deployment on your website.I would be glad to discuss your workflow, timeline, and technical approach further.

@rbtech1984

Hello There!!! ⚜⭐⭐⭐⭐⚜(( Web based quotation and sales management system with full ownership ))⚜⭐⭐⭐⭐⚜ Your brief is unusually clear and structured, which tells me you care about building a system that actually runs the business, not just generates quotes. This is a long term internal platform starting with quotations and pricing, then expanding into finance and performance tracking. You are looking for a fully web based solution hosted on your own website, with clear role separation between admin and sales users, precise pricing logic per square meter, and strict control over edits, history, and financial records. I have strong experience designing PHP based web applications with role based permissions, pricing engines, PDF generation, and customer level financial tracking. I focus on building clean data structures early so the system can grow step by step without rewrites. My approach would start with quotation flow and admin price lists, then layer invoices, payments, and analytics in controlled phases. Three core elements of the system: Admin managed pricing with automated quotation calculations Quotation to invoice workflow with version history Customer level financial tracking and sales performance statistics If you would like, we can start by mapping phase one and defining a clear delivery plan before development begins. Warm Regards, Farhin B.
