CORE DOMAIN CALCULATION ENGINE

The 13-Phase Pricing Architecture

The heart of Matrix UK is the calculator engine written in custom OOP PHP (class-pricing-calculator.php). It calculates base material rates, shapes, and frames in parallel for GBP and USD.

Calculation Phases

1. SQM Floor Enforcement: Min 0.5 SQM validation rule.
2. Material Rates Lookup: Reads custom meta cards dynamically (Earth, Green, Ecowood, Biowood, Basswood).
3. Style Discounts: Applies panel-only (-5.45%) or fixed (-3.45%) uplifts.
4-8. Custom Shapes Surcharges: Adds combi, arched, or tracked position parameters.
9. Buildout Rule: Sets fixed 20% surcharge if frame depth + buildout > 100mm.
10-12. Frame, Hinge, and Posts: Adds stiles, hinges (concealed/locking), and bay window post adjustments.

$sqm = ($width * $height) / 1000000;
if ($sqm < 0.5) $sqm = 0.5;

$base_gbp = $sqm * $material_rate_gbp;
$base_usd = $sqm * $material_rate_usd;

if ($frame_depth + $buildout > 100) {
    $surcharge = $base_gbp * 0.20;
}
if ($panel_width < 200) {
    $panel_fee = 30; // GBP
}

Custom Database Tables & Post Types

By avoiding the generic WordPress postmeta table mapping for configurator dimensions, Matrix UK leverages a optimized custom relational schema in MySQL:
