HubSpot Development

TL;DR

What it is: HubSpot development involves building custom themes, templates, integrations, and CRM configurations on the HubSpot platform. Businesses use HubSpot for marketing, sales, and customer service, and they need developers to customize it beyond what the default setup offers.

What you'll do:

• Build custom CMS themes, landing pages, and email templates using HubL
• Create workflow automations and CRM customizations
• Develop integrations between HubSpot and third-party tools
• Build and sell custom modules on the HubSpot Marketplace

Time to learn: 3-6 months if you already know HTML, CSS, and JavaScript, practicing 8-10 hours/week. Starting from scratch with no web development background, expect 9-15 months.

What you need: Web development fundamentals (HTML, CSS, JS), willingness to learn HubSpot's proprietary tools, and a free HubSpot developer account.

Note: Platforms may charge fees or commissions. We don't track specific rates as they change frequently. Check each platform's current pricing before signing up.

HubSpot development sits at the intersection of web development and marketing technology. Over 200,000 businesses use HubSpot, and most of them need customization that goes beyond the default templates and settings.

This isn't general web development. You're working within HubSpot's ecosystem, using their templating language (HubL), their CMS, their APIs, and their design tools. The upside is that this specialization means less competition. The downside is that your skills are tied to one platform.

What This Actually Is

HubSpot is a CRM and marketing platform that includes a CMS, email marketing, sales pipelines, customer service tools, and automation workflows. Companies pay significant monthly subscriptions for it, and they want it configured to match their specific business processes.

As a HubSpot developer, you're the person who makes that happen. You're not just building websites. You're building the technical infrastructure that marketing and sales teams rely on daily.

The work breaks down into a few main areas: CMS development (themes, templates, custom modules), CRM configuration (custom properties, pipelines, automations), integrations (connecting HubSpot to other tools via APIs), and marketplace products (themes and modules sold to other HubSpot users).

What You'll Actually Do

Day-to-day work varies, but here's what typical projects look like.

CMS and theme development is the most common entry point. You build custom website themes, landing pages, blog templates, and email templates using HubL, HubSpot's Jinja-based templating language. Clients want their HubSpot site to look and function differently from the default templates, and that's where you come in.

Custom module development involves creating reusable components that marketers can drag and drop into their pages. Think pricing tables, testimonial carousels, comparison charts, or interactive calculators. These modules need to be flexible enough that non-technical marketers can edit content without breaking layouts.

CRM customization means setting up custom properties, deal pipelines, lead scoring models, and automation workflows. A sales team might need their CRM to automatically assign leads based on territory, send follow-up sequences, or sync data with their accounting software.

Integration work connects HubSpot to other business tools. Common integrations include Salesforce, Shopify, QuickBooks, Slack, and various ERPs. You use HubSpot's APIs to ensure data flows correctly between systems.

Marketplace products are themes and modules you build once and sell to multiple HubSpot users. This is the closest thing to passive income in this space, though building quality marketplace products takes significant upfront effort.

Skills You Need

You need solid HTML, CSS, and JavaScript. These aren't optional. HubSpot's CMS is built on web technologies, and every customization requires them.

HubL is HubSpot's proprietary templating language based on Jinja. It handles variables, loops, conditionals, and macros. If you've used Jinja, Twig, or Liquid, HubL will feel familiar. If not, it's learnable but takes practice.

Understanding HubSpot's API is essential for integration work. You need to know how REST APIs function, how to authenticate requests, handle pagination, and manage rate limits.

CRM knowledge matters more than you'd expect. You need to understand how marketing funnels, sales pipelines, and customer lifecycle stages work. Without this context, you'll build technically correct solutions that don't actually serve the business need.

Basic design sense helps. You're often translating design mockups into HubSpot themes. Understanding responsive design, accessibility basics, and UX principles makes your work more valuable.

Getting Started

Start with a free HubSpot developer account. This gives you access to a sandbox portal where you can build and test without affecting live sites.

Get the HubSpot CMS Developer certification. It's free, covers the fundamentals, and signals credibility to potential clients. The certification covers HubL, the design manager, custom modules, and CMS best practices. Consider the CMS for Developers II certification once you're comfortable with the basics.

Build 2-3 portfolio pieces in your sandbox:

• A custom theme with at least 3-4 page templates
• Two or three custom modules with editable fields
• A simple integration that syncs data between HubSpot and another service

Learn the HubSpot CLI. It lets you develop locally with your preferred code editor and version control, rather than being stuck in HubSpot's browser-based design manager. This is how professional HubSpot developers work.

Consider listing a free or low-cost module on the HubSpot Marketplace. It demonstrates your ability to build production-quality components and generates visibility. You need at least 3 active installs from real users to maintain a marketplace listing.

Income Reality

Market rates vary based on experience, project type, and how you find clients. Income depends on your skill level, specialization, and time invested.

Some developers doing basic HubSpot CMS work like template modifications, simple landing pages, and email templates report earning ₹30,000-50,000/month part-time.

Intermediate developers handling custom themes, module development, and CRM configuration report ₹60,000-1,00,000/month. This typically requires understanding both the technical and marketing sides of HubSpot.

Experienced developers working on complex integrations, marketplace products, or serving as fractional HubSpot consultants report ₹1,50,000-2,50,000/month. Some charge ₹3,000-6,000/hour for consulting and architecture work.

Marketplace products can generate additional recurring income, though building quality themes takes weeks of development and ongoing maintenance effort.

These are market observations, not guarantees. Your actual income depends on skill, niche, effort, location, and market conditions.

What Different Work Actually Pays

Not all HubSpot work pays equally. Here's how different project types compare.

Template and landing page customization is the most accessible but lowest-paying work. It's a good starting point but hard to scale income on.

Custom module development pays better because it requires deeper HubL knowledge and the ability to create flexible, reusable components.

CRM configuration and workflow automation pays well because it directly impacts business operations. Clients see clear ROI when their sales process gets automated.

Integration development commands the highest project rates. Connecting HubSpot to Salesforce, ERP systems, or custom applications requires API expertise and careful data mapping.

Marketplace themes and modules offer the potential for recurring income without trading time for money, but the upfront investment is significant and competition is growing.

Where to Find Work

HubSpot's own ecosystem is the best starting point. The HubSpot Solutions Marketplace connects businesses with service providers. Getting listed requires some effort, but it puts you in front of buyers actively looking for HubSpot help.

Freelance platforms like Upwork and Fiverr have steady HubSpot development work. Search for HubSpot-related projects to see what clients are asking for. The demand outpaces supply on these platforms for developers with verified HubSpot skills.

HubSpot partner agencies often subcontract development work when they're overloaded. Building relationships with agencies gives you a steady pipeline without needing to find clients yourself.

The HubSpot Community forums and developer groups are where HubSpot users ask questions and look for help. Being active and helpful there builds your reputation and leads to inbound inquiries.

Direct outreach to businesses using HubSpot can work well. You can identify companies using HubSpot through their website source code or tools that track technology stacks. Reaching out with specific observations about how their HubSpot setup could improve is far more effective than generic pitches.

Common Challenges

Platform lock-in is real. Your HubL knowledge doesn't transfer to other platforms. If HubSpot changes direction or a client migrates away, your specialized skills lose value. Balance HubSpot-specific learning with broader web development skills.

HubSpot updates frequently. The platform changes features, deprecates APIs, and introduces new tools regularly. What you built six months ago might need updating. You need to stay current with HubSpot's changelog and developer blog.

Client subscription tiers limit what you can build. A client on HubSpot Starter has different capabilities than one on Enterprise. You'll regularly encounter situations where the best technical solution requires a higher subscription tier the client isn't willing to pay for.

Scope creep is constant. "Can you also set up our email sequences?" quickly follows a CMS project. Marketing teams often don't distinguish between development work and platform configuration. Set clear boundaries in your project scope.

Debugging across layers is frustrating. When something breaks, the issue could be in your HubL code, a HubSpot platform bug, a JavaScript conflict, or a CRM configuration problem. The layered nature of HubSpot's system makes troubleshooting slower than standard web development.

Tips That Actually Help

Get certified before pitching clients. The free HubSpot certifications take a few days each but significantly increase trust. Clients filter for certified developers.

Specialize in one area first. Trying to offer CMS development, CRM configuration, integrations, and marketplace products all at once dilutes your expertise. Pick one, get good at it, then expand.

Build templates and modules you can reuse across clients. A well-built base theme saves weeks of work on future projects and increases your effective hourly rate.

Learn to speak marketing, not just code. Your clients are marketers and sales teams. Explaining technical decisions in terms of conversion rates, lead generation, and customer experience resonates better than talking about code architecture.

Version control your HubSpot work with the CLI. It's tempting to do quick edits in the design manager, but you'll regret not having version history when something breaks.

Join the HubSpot developer community. The community forums and developer Slack channels are where you'll find answers to obscure HubL questions and hear about platform changes before they hit your projects.

Document your work thoroughly. HubSpot projects often get handed off to internal marketing teams or other developers. Clear documentation of custom modules, integrations, and configurations protects your reputation and reduces support requests.

Is This For You

HubSpot development works well if you enjoy web development but want to specialize in a platform with strong market demand and less competition than general freelancing. The combination of technical and marketing knowledge creates a niche that's harder for generalist developers to enter.

It's a good fit if you're comfortable learning a proprietary ecosystem and accepting the trade-off of platform-specific skills for higher rates and less competition. The marketing tech space values developers who understand business context, not just code.

It's not a great fit if you want maximum portability of your skills, prefer working with open-source technologies, or dislike working within platform constraints. The proprietary nature of HubL and HubSpot's tooling means you're investing in one ecosystem.

Note on specialization: This is a platform-specific field that requires understanding HubSpot's tools, APIs, and business context. Success depends heavily on knowing the nuances of HubSpot's ecosystem and how marketing teams actually use the platform. Consider this only if you have genuine interest in marketing technology and willingness to learn HubSpot's specific way of doing things.

If you already know HTML, CSS, and JavaScript, the learning curve is manageable. The free certifications give you a clear path, and the demand for skilled HubSpot developers consistently outpaces supply. Start with the CMS developer certification, build a few portfolio pieces in your sandbox, and take on a small project to test the waters.
