We default to declarative HubSpot configuration for one reason: it’s easier to maintain. Workflows, custom properties, and standard modules survive product updates without breakage. The next admin can read them. Most businesses don’t need a line of custom code. Then there’s the other 20% of cases. A CMS Hub website that needs more than the standard themes. A workflow that needs a custom-coded action because the declarative actions can’t reach. An integration with a proprietary system that doesn’t have a marketplace app. A custom module a marketing team uses across 50 landing pages. That’s where platform development comes in. This site — aeyecrm.com — runs on HubSpot CMS Hub. We use HubL daily. The work we do for clients is the work we do on our own. ## What HubSpot platform development covers CMS ### CMS Hub websites Full HubSpot CMS Hub website builds. Themed, branded, performant, with proper schema, sitemap, robots.txt, and meta management baked in. HubL ### HubL templating & custom modules Custom modules in HubL so marketing can spin up landing pages without engineering. Reusable, accessible, on-brand. Actions ### Custom-coded workflow actions JavaScript actions inside HubSpot workflows. Anything the HubSpot API can do, your workflows can do too. API ### HubSpot API integrations Server-to-server integrations with proprietary systems. Inbound webhooks, outbound API calls, and event-driven sync. Migrate ### Website migrations to CMS Hub WordPress to HubSpot. Webflow to HubSpot. Carrd to HubSpot. URL preservation, redirect maps, 301 chains, and schema migration. Optimize ### Performance & SEO Core Web Vitals tuning, image optimization, schema markup, structured data, and proper Open Graph/Twitter Card configuration. **Principle #7: Code is a liability, not an asset.** Every line of custom HubL you ship is something the next admin has to maintain. We write code only when declarative configuration can’t do the job — and we document why every time. ## How a HubSpot development project runs 1. ### Week 1: Requirements & alternatives review Document the requirement. Confirm declarative HubSpot configuration can’t solve it. Choose the lightest-weight technical approach. 2. ### Week 2: Technical design HubL module structure, custom-coded action design, API integration plan, theme structure. Reviewed before code is written. 3. ### Week 3-4: Build & test Code written in a staging environment. Module testing in design preview, action testing with sample data, API testing with sandbox endpoints. 4. ### Week 5: Deploy & document Deploy to production. Deliver written documentation: what the code does, why it exists, how to debug it, and how to extend it. 5. ### Ongoing: Maintenance HubSpot product updates occasionally break custom code. We maintain what we built or hand off clean documentation. ## Who this is for ### A good fit if you’re… - Declarative HubSpot workflows can't handle your automation requirement - Need a custom module marketing can reuse without engineering - Migrating a WordPress, Webflow, or Carrd site to CMS Hub - Integrating with a system that has no marketplace app - Need a CMS Hub website with real performance and SEO standards ### Not a fit if you want… - Want code written before declarative options are exhausted - Need cheapest possible HubL developer-hour rate - Looking for offshore staff augmentation only - Don't want tests, documentation, or code review **Independent HubSpot Consultants · HubSpot & Salesforce Experience**Marketing Hub, Sales Hub, Service Hub, CMS Hub, Operations Hub.

[Book a Call](https://calendar.app.google/dFQEPDnkW4JizDkr5) ## Frequently asked questions How much does HubSpot development cost? Development engagements start at $3,000 for focused work (a single custom module, a single workflow action, a small CMS Hub setup). Larger custom builds land in the $15K-$50K range. Do you build full HubSpot CMS Hub websites? Yes — full builds and migrations from WordPress, Webflow, Carrd, and Squarespace. We run this site on CMS Hub. We know the platform deeply. Can you write HubL templates and custom modules? Yes — HubL is our daily working language. Custom modules, partials, theme components, and template overrides for blog, landing pages, and site pages. Do you do HubSpot-WordPress migrations? Yes. URL preservation, 301 redirect maps, schema migration, and template rebuilds in HubL. We’ve done WordPress, Webflow, Carrd, and Squarespace migrations to CMS Hub. Can you fix custom HubL written by another developer? Yes. We do code review, refactoring, and bug fixes on inherited HubL. Sometimes faster to rewrite than to fix — we’ll be honest about which one your code is. ## Related HubSpot services [Implementation →](https://aeyecrm.com/crm-services/hubspot/implementation-services)[Integration →](https://aeyecrm.com/crm-services/hubspot/integration-services)[Customization →](https://aeyecrm.com/crm-services/hubspot/customization-services) ## Build the HubSpot code your business actually needs — and nothing more Sales Process Automation, built on The 7 Principles.
