Deliverables

Context

Multi-Prêts is one of Quebec’s largest mortgage brokerage networks, connecting thousands of Canadians with the best mortgage rates and financing solutions. As the flagship brand of the M3 Tech group, Multi-Prêts operates a high-traffic enterprise website serving both brokers and consumers across the province.

Multi-Prêts is one of five brands of the M3 Tech group that share one WordPress platform: one parent theme and block library, with a child theme per brand. WPlook Studio took the platform over from a previous agency and developed it from 2021 to 2025, as one engagement covering all five brands. Our role covered WordPress and systems architecture: the front-end redesign, custom Gutenberg blocks, the broker, office and franchise backend, infrastructure and SEO consulting. This page gives the most detail of the five, including the blocks built for the Multi-Prêts child theme. The other brands on the platform are Mortgage Alliance, Invis, Mortgage Intelligence and Intelligence Hypothécaire.

The Challenge

The existing platform suffered from 16-second page loads, an infrastructure sprawl of 12 Azure servers, and a codebase that needed modernization. Multi-Prêts needed someone who could manage the full stack, from the Azure servers to the front end, and work with product owners, marketing teams and stakeholders to keep improving the platform.

What We Delivered

Custom Gutenberg Blocks & Front-End Redesign

  • Built 32 custom Gutenberg blocks in the M3 parent theme, the one block library all five brands share: section, row, column, display, hero, background, toggle-content, latest-posts, category-list, page-relations, regions and accordion blocks
  • Developed 15+ additional blocks in the Multi-Prêts child theme: CTA variants (9 styles), container, header and a dynamic locations-list block pulling from the BOSS API
  • Built dynamic blocks for mortgage rates, lenders, broker information, broker locations, and broker list
  • Developed server-rendered blocks for contact forms, contest forms, newsletter signup and job applications
  • Redesigned the front-end using Bootstrap 5 with custom SASS theming and brand-specific color overrides

Backend: Broker, Office & Franchise Management

  • Built custom post types for Employees (brokers), Offices, Franchises, Regions, Jobs, and Mortgage Lenders
  • Integrated with the BOSS API: a JWT-authenticated sync brings broker, office and franchise data from the CRM in real time
  • React-based admin interfaces for managing broker profiles, office locations, and franchise data
  • Custom admin columns, sortable fields, and force-update meta boxes for manual sync triggers
  • Broker-specific features: per-broker GTM codes, Facebook pixels, custom action links, and canonical URL handling

Mortgage Calculators & Interactive Tools

  • 7 interactive mortgage calculators: affordability, payment, refinance, rent-vs-buy, debt consolidation, closing fees, and custom rate calculator
  • Dynamic rate display by province with data from BOSS API’s Rate_Merge system
  • Broker search with Google Maps API integration and geocoding
  • Custom mega menu system with broker-specific link injection and mega menu features

SEO & Structured Data

  • JSON-LD structured data: Organization, LocalBusiness, Financial Service and Breadcrumb schemas
  • Custom broker sitemap added to robots.txt for search engine indexing
  • SEO consulting across all 5 M3 brands: keyword strategy, Core Web Vitals optimization and technical SEO audits
  • Bilingual support via Polylang with hreflang tags and brand-specific translation strings

Infrastructure & Performance

  • Migrated from Azure Web App to Azure VM with cPanel for better control
  • Consolidated 12 servers down to 2 (production + staging), eliminating auto-scaling
  • Webpack 5 build system with code splitting: blocks, frontend, and admin bundles
  • CI/CD pipelines for continuous deployment
  • Didomi consent management for GDPR/privacy compliance
  • Google Tag Manager with per-brand container IDs

Results

  • Page load reduced from 16s to under 1s on the shared platform
  • 12 servers consolidated to 2 (production and staging) on Azure, which the group already used, lowering hosting costs
  • 47+ custom Gutenberg blocks across parent and child themes
  • 7 mortgage calculators with dynamic rate data
  • Improved Core Web Vitals across all properties
  • Faster deployment cycles through modernized CI/CD
