What HubSpot integrations does Big Presence build?
Big Presence builds HubSpot integrations for field service, payments and finance, bookings and operations, and marketing software, plus custom API integrations for anything else. Examples include BigChange, Stripe, Xero, Airtable and booking platforms. Every integration runs through middleware, so if a platform changes its API, Big Presence updates the middleware instead of rebuilding.
- Who builds them: Big Presence, a HubSpot Platinum Solutions Partner based in Wilmslow, Cheshire, UK.
- Partner status: a BigChange partner and implementation partner, and a Simpro partner.
- How they are built: through a middleware layer between HubSpot and the other software.
- Price: a fixed price once the work is scoped.
- After launch: we host and support it, or hand over the working code and repository.

Why do businesses come to Big Presence for HubSpot integrations?
HubSpot is strong at sales and marketing. However, the rest of the business often runs somewhere else, and the gaps cost time.
The same data typed twice
Customers go into HubSpot, then again into the job, booking or finance system.
No single version of a customer
Each system holds part of the story. As a result, nobody sees the whole thing.
Off-the-shelf connectors that fall short
A standard connector covers the basics, but not the way your business actually works.
Which software can Big Presence connect to HubSpot?
Pick a category, or scroll the full list. Each page then explains what moves between the systems and how we build it.
| Software | Category | What the integration does |
|---|---|---|
| BigChange | Field service | Customers, sites, contacts and jobs created in BigChange from HubSpot. |
| Simpro | Field service | Our approach to connecting Simpro and HubSpot, as a Simpro partner. |
| JobLogic | Field service | Sales, payments and jobs talking to each other. |
| Stripe | Payments and finance | Custom logic around payments, deal stages and deposits. |
| Xero | Payments and finance | Help when the standard Xero connection is not enough. |
| Booking platforms | Bookings and operations | Course and event bookings in the same record as the customer. |
| Link (Bikeability) | Bookings and operations | Bookings in HubSpot create deliveries in Link. Outcomes then come back. |
| Airtable | Bookings and operations | Operations in Airtable and sales in HubSpot, kept in step. |
| PandaDoc and e-sign | Bookings and operations | Contract and signature data back in HubSpot. |
| n8n, Instantly, ActiveCampaign | Marketing | Campaigns and outbound sent elsewhere, with HubSpot as the record. |
| Anything else | Custom | Custom API integration and middleware for software not listed here. |
Looking for an off-the-shelf app instead? HubSpot lists ready-made connectors in its App Marketplace. We help, however, when those do not fit how your business works.

How is every HubSpot integration built?
Every integration runs through a middleware layer between HubSpot and the other software. Middleware is a small service in the middle that moves and translates the data. So if one platform changes its API, we update the middleware instead of rebuilding.
Scope
Which systems, how they connect and roughly how much data flows.
Map
Every field agreed: where it lives and which system owns it.
Build and test
We build and test, then your team tests before go live.
Host and support
We host it or hand it over, and support it after launch.

HubSpot integrations FAQs
How much does a custom HubSpot integration cost?
A custom HubSpot integration typically costs between £3,000 and £8,000 plus VAT when it connects one system to HubSpot, and between £10,000 and £30,000 plus VAT for multi-system builds or complex two-way logic. Most go live in 3 to 8 weeks. We confirm a fixed price once the project is scoped, and new scope gets a new estimate.
How long does a HubSpot integration take?
The time a HubSpot integration takes depends on the number of systems and data flows. We give you a timeline after scoping. Every project follows the same stages: scope, map, build and test, your testing, go live and support.
My software is not on the list. Can you still connect it?
Software that is not on the list can usually still be connected to HubSpot. Our custom API and middleware page explains how we approach software we have not connected before.
Why not use a ready-made app from the HubSpot App Marketplace?
A ready-made app from the HubSpot App Marketplace is the right choice if it does what you need. We build custom integrations when your process, data or systems need more than a standard connector offers.
Who looks after the integration once it is live?
A live HubSpot integration can be hosted and looked after by Big Presence through a monthly support package, or hosted by you with the code and repository handed over.
What do you need from us?
Big Presence needs access to the software, API documentation or credentials, a test account where possible, and information within 5 working days of asking.
Not sure which integrations you need?
A Growth Gap Analysis finds where your business is losing growth before we build anything. Alternatively, book a scoping call if you already know what you want to connect.
