Read our most frequently asked questions about custom integrations to discover solutions for common challenges.

What is a custom HubSpot integration?

A custom HubSpot integration is a tailored connection between HubSpot and another system that’s built using code to meet your specific business needs.

Unlike pre-built or native integrations, custom integrations allow for precise data syncing, workflow automation, and functionality that aligns with your unique processes and tech stack.

When do I need a custom integration instead of an out-of-the-box HubSpot connector?

You need a custom HubSpot integration instead of an out-of-the-box connector when your systems or workflows require functionality that native integrations can’t support.

This includes syncing with niche platforms, enabling advanced data mapping, or automating complex processes that standard connectors don’t handle effectively.

What types of systems can Mole Street integrate with HubSpot?

Mole Street can integrate HubSpot with a wide range of systems. This includes CRMs like Salesforce and Dynamics, ERPs like NetSuite and SAP, accounting and practice management platforms like Practice CS and STAR, and custom-built tools.

If the system has an accessible API, we can likely build a secure and reliable integration.

How long does a custom HubSpot integration typically take to complete?

A custom HubSpot integration typically takes 4 to 12 weeks depending on the complexity of the systems involved, the level of customization required, and the clarity of your integration requirements.

We follow a phased process that includes discovery, development, testing, and deployment to ensure accuracy and minimal disruption.

Will a custom integration cause downtime or impact business operations?

A custom integration with Mole Street is designed to avoid downtime and minimize disruption to your operations.

Our team builds, tests, and deploys integrations using a controlled rollout approach, ensuring business continuity while creating a seamless transition to your unified system.
