Most HubSpot problems don’t need code. The ones that do, really do.

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.

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.
