Build a custom coded HubSpot JavaScript solution

Need HubSpot to do something that isn't possible using standard workflow actions?

I develop custom JavaScript solutions inside HubSpot to extend the platform and automate complex CRM processes.

Custom code can retrieve, process, calculate and update data in ways that aren't possible using HubSpot's standard workflow tools.

I can build solutions for:

✔️ Processing associated contacts, companies and deals
✔️ Combining data from multiple associated records
✔️ Complex calculations and business rules
✔️ Creating intelligent customer or deal statuses
✔️ Data transformation and validation
✔️ Automated summaries and calculated outputs
✔️ Advanced workflow decision logic
✔️ Record creation and updating
✔️ Lead or record allocation logic
✔️ API calls and external data processing
✔️ Multi-pipeline and multi-deal processes
✔️ Other requirements beyond standard HubSpot functionality

How it works

Tell me what you need HubSpot to achieve, rather than worrying about how it should be coded.

I'll review the requirement and determine whether custom code is the right solution.

I'll then design, develop and test the JavaScript action and integrate it into your HubSpot workflow.

Where appropriate, I'll include safeguards, error handling and logging so the solution isn't simply code that works once, but something that can operate reliably as part of your CRM.

What you'll receive

The £350 Offer covers one clearly defined custom-coded HubSpot solution, including:

Requirement review → solution design → JavaScript development → HubSpot implementation → testing

Larger applications, extensive API integrations or solutions requiring multiple custom-coded actions can be scoped separately.
