BigChange HubSpot integration, built and looked after
A BigChange HubSpot integration connects HubSpot to BigChange, so leads, quotes and jobs line up, without anyone typing the same customer in twice.


What is a BigChange HubSpot integration?
A BigChange HubSpot integration connects HubSpot, where your sales and marketing run, to BigChange, where your jobs and field teams run. Big Presence builds it through a middleware layer, so customers, sites, contacts and jobs created in HubSpot appear in BigChange without anyone retyping them.
- Who builds it: Big Presence, a HubSpot Platinum Solutions Partner and a BigChange partner and implementation partner.
- Experience: several BigChange to HubSpot integrations built, for clients from £1m to £50m+ turnover.
- How it is built: through middleware, so an API change means an update, not a rebuild.
- Price: fixed once scoped. New scope gets a new estimate.
- After launch: we host and support it, or hand over the working code.

Why connect BigChange to HubSpot?
Many BigChange users run sales and marketing in a separate system or a spreadsheet. BigChange has CRM tools of its own, but teams that use HubSpot for sales and marketing still need the two to agree. As a result, when the two disagree, you see this:
Double entry and duplicates
The office retypes customers from the sales system into BigChange. As a result, small differences create duplicate records.
Won work that stalls
A deal is won in HubSpot, but the job does not appear in BigChange until someone remembers to create it.
Quotes sitting in inboxes
Quotes live in email threads. So nobody can see which ones need chasing.
No marketing numbers next to jobs
You cannot see which campaigns produced the jobs your engineers are out doing.
Reports you cannot trust
Sales reports and job reports come from different places, so the numbers never match.
What data does a BigChange HubSpot integration move?
Every build starts from your process. These are the data flows we design around. In most builds, HubSpot is the source of truth for customer data, while BigChange runs the work.
| From | To | What moves | Direction |
|---|---|---|---|
| HubSpot | BigChange | Customer, site and contact records, created or updated | One way |
| HubSpot | BigChange | Jobs and their line items, created from HubSpot | One way |
| HubSpot | BigChange | Companies with several sites, kept in the right structure | One way |
| HubSpot | BigChange | Updates agreed at scoping, using API calls in both directions | Two way |
| BigChange | HubSpot | Job status and completion | Back to HubSpot |
BigChange offers a REST API and event-driven webhooks. An API is the doorway one system uses to read and write data in another. In addition, webhooks let BigChange tell the middleware when something happens. Meanwhile, HubSpot has its own developer API on the other side.
How is a BigChange HubSpot integration built?
Scope
First, we look at your systems, how they should connect and roughly how much data flows. Then we give you a fixed price.
Map
We map every field: which system owns it, what it is called in each, and what happens when it changes.
Build and test
Next, we build the middleware and test it. Your team then tests it in user acceptance testing before go live.
Host and support
Finally, we stay after go live. That means we monitor the integration and keep it working through ongoing support.
Has Big Presence built BigChange HubSpot integrations before?
A UK renewable energy and retrofit delivery partner
We connected HubSpot Enterprise to their core systems by API, including two-way calls between HubSpot and BigChange. As a result, HubSpot is now a single source of truth across sales, operations and customer engagement. This integration is live.
A UK renewable energy provider
We integrated HubSpot Sales Pro and Marketing Pro with their field service software. Survey bookings, quotations and follow-ups are now connected, so they get better reporting across surveys and sales. This integration is live.
Why choose Big Presence for BigChange and HubSpot?
We are a revenue operations partner, not just a HubSpot implementer.
Partners on both sides
We are a HubSpot Platinum Solutions Partner and a BigChange partner and implementation partner. In fact, we are the only business that is a partner of both BigChange and Simpro.
Done this before
We have built several BigChange to HubSpot integrations, for clients from £1m to £50m+ turnover.
Built to survive change
Our integrations run through a middleware layer. So if BigChange or HubSpot changes its API, we update the middleware instead of rebuilding.
Who hosts and supports a BigChange HubSpot integration?
We host it
We host the middleware and look after it. That includes monitoring it, fixing breakages, handling API changes and rotating keys.
You host it
Prefer to keep it in house? We hand over the working code and the repository.
Ongoing support runs through a monthly support package: Big, Bigger or Biggest. We also help you pick the right one at scoping.
BigChange HubSpot integration FAQs
How much does a BigChange HubSpot integration cost?
A BigChange 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 it take?
The timeline for a BigChange HubSpot integration depends on how many systems and data flows are involved. We give you a timeline once scoping is done. Every project runs through the same stages: scope, map the data, build and test, your testing, go live, then ongoing support.
Do I need a certain BigChange plan to use the API or webhooks?
The integration needs access to the BigChange API and webhooks. BigChange controls API permissions and keys, so check with BigChange that your plan includes API and webhook access. We can help you ask the right questions.
Who hosts the middleware?
The middleware can be hosted by Big Presence or by you. If we host it, we look after it, including monitoring, fixes, API changes and key rotation. If you host it, we hand over the working code and repository.
Can you connect more than one BigChange account?
Big Presence can connect more than one BigChange account to one HubSpot portal. We look at how your accounts are set up during scoping and design the middleware around it.
Does HubSpot replace BigChange?
HubSpot does not replace BigChange. HubSpot runs sales and marketing, and BigChange runs jobs and field teams. The integration lets each system do its own job while sharing the data both need.
What happens if BigChange or HubSpot changes its API?
When BigChange or HubSpot changes its API, Big Presence updates the middleware instead of rebuilding the integration. That is the reason every integration runs through middleware.
What do you need from us to get started?
To start a BigChange HubSpot integration, we need access to the software, API documentation or credentials, a test account where possible, and information within 5 working days of asking.
