HubSpot rarely runs a business on its own. It sits at the center of the revenue stack and connects out to the systems that finish the job — finance, payments, e-signature, data, and support. Done well, HubSpot integrations turn a pile of disconnected tools into one connected revenue process. Done badly, they create duplicate data, broken syncs, and a CRM nobody trusts. This guide covers the integrations that actually matter for revenue teams and how to choose an approach.
What is a HubSpot integration?
A HubSpot integration is a connection that moves data between HubSpot and another system so the two stay in sync. That can be as simple as pushing form fills into HubSpot, or as involved as a two-way sync between your CRM and your ERP where a closed deal becomes a sales order and invoice status flows back to sales. The value isn't the connection itself — it's that every team works from the same numbers.
Types of HubSpot integrations
- ERP & finance — the highest-impact integration for most revenue teams: connecting HubSpot to an ERP like NetSuite so quote-to-cash runs end to end.
- Payments & e-signature — collecting signatures and payment on the deal record through Commerce Hub.
- Data & reporting — syncing HubSpot with a data warehouse or BI tool for a single source of revenue truth.
- Marketing & ads — connecting ad platforms and marketing tools for closed-loop attribution.
- Support & success — tying help desk and customer data back to the account so sales and CS share context.
The integration that matters most for quote-to-cash
For revenue teams, the CRM-to-ERP connection is the one that pays for itself. It's the seam where sales hands off to finance — and the seam where quotes stall, invoices lag, and forecasts drift when it's manual. Our flagship build is the HubSpot–NetSuite integration, which turns a closed deal into a sales order automatically and syncs fulfillment and invoice status back to sales. If you're weighing the two systems first, see NetSuite vs HubSpot, and for the full picture read how a HubSpot NetSuite integration works. It's the backbone of a connected quote-to-cash process.
Popular HubSpot integrations we build
The integrations revenue teams ask us for most — each one closing a specific gap in the quote-to-cash process:
- HubSpot & NetSuite — the CRM-to-ERP backbone: deals become sales orders, fulfillment and invoices sync back.
- HubSpot & Salesforce — two-way sync when you run both, or a clean migration onto HubSpot.
- HubSpot & QuickBooks — sync customers, invoices, and payment status for smaller finance stacks.
- HubSpot & Stripe — collect payments on quotes and track subscriptions and ARR in the CRM.
Native connector vs iPaaS vs custom
There are three ways to build a HubSpot integration, and the right one depends on your process:
- Native / marketplace connector — fastest to stand up, but limited to the fields and logic the connector predefines.
- iPaaS middleware — flexible and visual, good for many-system workflows, with an ongoing subscription cost.
- Custom integration — built on HubSpot's open APIs and tailored to your exact process, for when off-the-shelf can't model how you actually work.
Common integration pitfalls
- Syncing everything instead of the fields that actually drive decisions.
- No clear source of truth, so the two systems drift out of sync.
- One-way syncs that leave one team blind to what the other sees.
- No plan for maintenance, so the integration quietly breaks after a schema change.
HubSpot integrations FAQs
What integrations does HubSpot have?
HubSpot connects to well over a thousand tools through its App Marketplace, spanning ERP and finance, payments, e-signature, data warehouses, marketing and ads, support, and more. Beyond marketplace connectors, HubSpot's open APIs let you build custom integrations for anything not covered off the shelf, such as a tailored CRM-to-ERP sync.
How do I integrate HubSpot with another system?
There are three common paths: a native or marketplace connector (fastest, but limited to predefined fields), an iPaaS middleware platform (flexible, with ongoing cost), or a custom integration built on HubSpot's APIs (tailored to your exact process). The right choice depends on data volume, how custom your process is, and how much control you need.
Are HubSpot integrations free?
Many App Marketplace connectors are free or included with your HubSpot subscription, though some third-party apps and iPaaS platforms charge separately. Custom integrations are a build cost. The larger cost is usually not the connector itself but scoping, mapping, and maintaining the sync so the two systems stay accurate.
