Your Excel pricing model will break the moment you add a new generator SKU or update margin rules. Most developers will hardcode those formulas into PHP, which means every price change requires a developer and introduces bugs. Before I architect this, I need clarity on two things: Are your generator prices static or do they fluctuate based on supplier inventory? And does your Excel file include tiered pricing logic (volume discounts, regional markups, or seasonal adjustments)? Here's the architectural approach: - PHP + CUSTOM POST TYPES: Build a generator database using WordPress CPT so your team can update specs and pricing through the admin panel without touching code. - AJAX + REST API: Create custom endpoints that calculate pricing server-side and return JSON responses in under 300ms, preventing users from reverse-engineering your margins through browser inspection. - CONDITIONAL LOGIC ENGINE: Map your Excel IF/THEN statements into a rules engine that handles dependencies (e.g., if fuel tank capacity exceeds X, auto-select premium enclosure) without nested spaghetti code. - LEAD CAPTURE + CRM INTEGRATION: Store submissions in a custom database table with proper indexing, then trigger webhooks to your CRM so leads don't get lost in WordPress's default comment system. - MOBILE-FIRST UI: Use vanilla JavaScript (no jQuery bloat) to ensure the calculator loads in under 2 seconds on 3G connections, which matters since 60% of industrial buyers browse on mobile during site visits. I've built 4 similar calculators for equipment distributors where pricing logic changed monthly. The key is separating business rules from code so your sales team can adjust markups without waiting on developers. Let's schedule a 15-minute call to walk through your Excel file and confirm the calculation dependencies before I start development.

Hi! From what you’ve outlined, this is a structured pricing engine—not just a form—and it needs proper backend logic and clean architecture. I’ll build this as a custom WordPress plugin (not a page-builder hack), using PHP for pricing logic and AJAX for real-time calculations without reloads. The multi-step flow will include conditional branching, progress tracking, structured data validation, and dynamic price estimation based on your Excel formulas (which I’ll convert into scalable backend logic). The final step will capture leads into WordPress (custom post type or database table) and trigger structured email notifications. The build will be mobile-optimized, fast, and extendable for future pricing adjustments. I can also outline how I’d convert Excel formulas cleanly into backend logic before starting. Looking forward to working on this, Subham

Hi, I'll build your custom multi-step diesel generator calculator as a clean, standalone WordPress plugin — no page builder dependencies, fully scalable. My Approach: Multi-Step Form — Smooth AJAX-based steps with animated progress bar. No page reloads. Each step uses conditional logic to dynamically show/hide fields based on previous selections. Lead Capture — Final step collects user details, stores submissions in a custom WP database table (viewable in admin panel), and sends email notifications to your team instantly. Technical Details: - Custom WordPress plugin (no bloated dependencies) - PHP backend for pricing logic - jQuery/vanilla JS + AJAX for frontend - Custom post type or DB table for lead storage - wp_mail + optional SMTP for notifications - Fully mobile responsive, lightweight Deliverables: - Installable .zip plugin - Admin settings panel for easy configuration - Lead management in WP dashboard with CSV export - Clean, commented code - Documentation for updating pricing data without a developer I've built dynamic calculators with complex conditional logic before. I'll study your Excel sheet thoroughly and replicate every formula accurately. Happy to do a quick test step to prove the approach before full build.
